How to test if your home locks are pick-resistant

May 20, 2025

In an age where security threats can be both digital and physical, protecting your home starts at the front door—literally. While you might invest in surveillance cameras or motion sensors, the very first line of defense is your lock. But here's the critical question: is your home lock truly pick-resistant? Many homeowners assume their locks are secure simply because they’re installed or come from a known brand. However, not all locks are created equal, and some can be picked in mere seconds with basic tools. That’s why testing your locks for pick-resistance isn’t just smart—it’s essential. Let’s walk through how to evaluate the security of your home locks the right way.


What to do if your front door lock keeps spinning!



Understanding What “Pick-Resistant” Really Means

Before diving into the test, it’s important to understand what pick-resistance actually involves. A pick-resistant lock isn’t pick-proof—there’s no such thing as a completely unpickable lock. What makes a lock “resistant” is its ability to withstand tampering through traditional lockpicking techniques like single pin picking, raking, or bumping.

High-security locks often feature security pins (like spool or mushroom pins), complex keyways, and reinforced cores. These design elements increase the difficulty of picking but don't guarantee immunity. A truly pick-resistant lock buys you time and discourages intruders—not just by physical resistance but by psychological deterrent.


Start with a Visual Inspection: Clues from the Outside

Sometimes, you don’t need fancy tools to know your lock might be vulnerable. Start with a close visual inspection. Look at the keyway—if it’s wide and smooth, that could mean it's easier to insert a lockpick or bump key. Simpler locks, like older pin tumbler designs or basic knob locks, usually lack internal complexity.

Next, examine the faceplate or cylinder. Do you see any markings like “ANSI Grade 1” or “Grade 2”? Grade 1 is the highest residential rating and usually indicates a more secure build. Brands like Medeco, Mul-T-Lock, and Schlage Primus typically incorporate extra anti-pick features, whereas off-brand or low-cost hardware store locks tend to cut corners.

This isn't a foolproof method—but as a first step, it offers valuable hints.


Step-by-Step: Simulate a Lock Picking Attempt (Responsibly)

Now comes the part that requires more care—testing the lock manually. While you don’t need to be a locksmith to perform a basic check, you do need to be responsible. If you're not experienced, we don’t recommend trying to pick your own locks, as you could damage the mechanism or unintentionally compromise your security. However, you can hire a trusted locksmith or use a lock-testing kit specifically designed for educational purposes.

If you do proceed with testing (with caution and consent):

  1. Use a practice lock first. Before touching your actual home lock, try a transparent lock or repurposed lock with a lockpick set to understand how lockpicking works.
  2. Attempt basic raking or tensioning. Use a tension wrench to apply slight torque and a rake pick to jiggle the pins. If the lock opens quickly, that’s a red flag. Most low-grade locks will yield within seconds to this method.
  3. Test with a bump key. Bump keys can open many locks with a quick strike. If your lock is susceptible to bumping, it lacks pick-resistance. Again, use caution—bumping can damage a lock over time.
  4. Record resistance time. If the lock resists for more than a couple of minutes, it likely has anti-pick features like spool or serrated pins.

Remember, these tests should never be used on someone else's property and should only be done on your own locks or in professional settings. If unsure, consult a certified locksmith.


Red Flags: Signs That Your Lock Is Easily Pickable

When assessing the pick-resistance of your home locks, some warning signs are easy to spot—if you know what to look for. These red flags could mean your lock isn’t just outdated, but dangerously vulnerable to intrusion. Let’s walk through each one in detail, so you know exactly what to check and why it matters.

1. The Lock Feels Loose or Wobbly

A well-secured, quality lock should feel solid when you insert the key. If the cylinder wiggles, shifts, or feels like it’s not anchored properly inside the door, that’s a major vulnerability. Loose hardware makes it easier for intruders to manipulate the internal mechanisms with basic lockpicking tools or bump keys. It also signals wear and tear that can weaken overall protection. In many cases, criminals look for these signs because they indicate a potential quick win.

2. Key Turns Too Easily or Offers No Resistance

Every lock should offer some tactile feedback—some resistance—when turning a key. If your lock turns without any effort or tension, it might be a sign that the internal pins are worn down or the tolerances are too loose. In pick-resistant locks, the pins are designed to make picking more time-consuming and difficult. When resistance is absent, the lock becomes far easier to bypass with even beginner-level tools. This seemingly small detail can make all the difference between a secure home and one that's vulnerable.

3. Wide-Open or Oversimplified Keyway Design

Take a close look at your lock’s keyhole, also known as the keyway. Is it wide and straight, with plenty of room to insert things other than your key? Simpler keyway designs are more susceptible to lockpicking, because they offer pick tools plenty of maneuvering room. High-security locks often use paracentric or complex keyways, which curve or restrict access, making it significantly harder for intruders to manipulate the lock. A basic keyway might look harmless—but it can be a major weak point.

4. You Can Open It With a Paperclip or Bobby Pin

Let’s be honest—if your lock can be jimmied open with something as basic as a bobby pin, paperclip, or cheap lockpick set, it’s time for an upgrade. While it's tempting to see this as a fun DIY experiment, what it really shows is that the lock isn't built to withstand even the most amateur-level intrusion attempts. Any lock that offers so little resistance to such improvised tools shouldn’t be securing anything more valuable than a toy chest—let alone the front door to your home.

5. No Sign of Certification or Security Rating

Professional-grade locks are typically certified by ANSI (American National Standards Institute) or BHMA (Builders Hardware Manufacturers Association), which test for things like durability, pick resistance, and force tolerance. If your lock doesn’t have a visible grade or rating—like ANSI Grade 1, 2, or 3—it may not have passed any security standard at all. Locks that skip this certification process are often mass-produced with cheap materials and zero anti-pick design features. Always look for a rating—it’s more than just a label, it’s your first line of defense.

6. It’s From a No-Name or Bargain Brand

We all like a good deal, but with locks, you really do get what you pay for. Locks made by unknown manufacturers or sold under generic labels often lack innovation, durability, and proper quality control. These budget-friendly locks typically forgo any internal security pins or special features that resist picking or drilling. In contrast, brands known for security—like Medeco, Schlage, or Mul-T-Lock—build products with enhanced protection in mind. If you can’t trace the brand or find security specs, that’s a problem in itself.

7. The Lock Is Old—Over 10 Years or More

Locks age just like any mechanical system, and older models weren’t built with today’s burglars in mind. A lock that’s been installed for more than a decade is likely missing critical updates in design and materials. For example, it might not have spool pins, sidebar mechanisms, or anti-drill plates—features that are now standard in high-security locks. Even if the lock hasn’t failed yet, the longer it’s been in service, the more likely it is to give way under stress. Think of an old lock like a worn-out tire—it may work for now, but it’s no longer safe.


Expert Recommendations: When to Upgrade Your Lock

If your lock fails the basic test—or you simply want peace of mind—consider investing in high-security locks certified by recognized standards. Brands like ASSA Abloy, Medeco, and Mul-T-Lock offer bump- and pick-resistant designs, often using sidebar mechanisms and complex pin systems.

Professional locksmiths recommend replacing locks every 5-10 years, especially if you’ve recently moved in, lost keys, or had a break-in nearby. Always choose locks with an ANSI/BHMA Grade 1 rating for residential doors. For even better security, consider pairing the lock with a smart deadbolt that alerts you of tampering attempts in real time.


Additional Preventive Measures for Lock Security

Even the best lock benefits from backup security. Reinforce the door frame with strike plates and longer screws to prevent forced entry. Use a door camera or peephole to monitor outside activity. If you're tech-savvy, smart locks with biometric or coded entry can offer another layer of protection—though they come with their own learning curve and maintenance.

Finally, don’t underestimate the power of routine checks. Lubricate your locks, test the tension, and replace keys as they wear down. Maintenance ensures your locks remain in good shape—and keeps you alert to changes that could signal a problem.


Conclusion: Make Security a Habit, Not Just a Hardware Choice

Your home’s safety depends on much more than a sturdy lock—but the lock is where it begins. By testing your locks for pick-resistance, you're taking a proactive step toward security, awareness, and peace of mind. Whether you hire a professional or test with a kit, the insights you gain are invaluable. And if you discover vulnerabilities, don’t panic—use it as an opportunity to upgrade to a stronger, smarter locking system.

Because in home security, it’s better to be proactive than reactive—and better safe than sorry.

Wondering if a locksmith can fix your water-damaged car key fob? Discover how water affects key fobs, what to do immediately after damage, and how Brothers Locksmith can repair, reprogram, or replace your fob quickly and affordably — anytime, anywhere.
By Youmna Rehman October 6, 2025
Modern vehicles are wonderfully convenient — push-button starts, keyless entry, and digital fobs make daily life easier. But convenience creates new attack surfaces. A key fob relay attack is a type of theft where criminals amplify or relay the signal from your car’s key fob so that the vehicle “thinks” the fob is nearby and unlocks or starts. In recent years, these attacks have grown in frequency because they can be carried out quickly with relatively inexpensive equipment. The result: owners return to find their car gone and insurance claims that are messy and stressful. Understanding how relay attacks work and what you can do to prevent them is essential for every modern car owner. How Mobile Apps Are Revolutionizing Automotive Lock Services What Is a Key Fob Relay Attack? A relay attack uses two devices and two attackers (or one attacker with two devices). One device is placed near the car to capture signals; the other is placed or carried near the house where the legitimate key fob is stored. The devices communicate, relaying the key fob’s signal to the car so it behaves as if the owner is standing next to it. Once the vehicle is unlocked, thieves can often start it and drive away. Importantly, the criminals don’t need to hack encryption or physically touch the key — they simply extend the fob’s wireless presence. Why Keyless-Entry Systems Are Vulnerable Keyless systems were designed for convenience, not to withstand the creative methods thieves now employ. Many fobs broadcast low-power radio signals that are sufficient for short-range use but can be picked up and boosted. Manufacturers added rolling codes and encryption to combat simple replay attacks, but relay attacks bypass these protections by forwarding the live signal rather than replaying a recorded one. Additionally, vehicles that rely purely on proximity checks without additional authentication are intrinsically more exposed. Signs Your Car May Have Been Attacked Detecting a relay attack can be tricky because it often leaves little forensic. However, there are clues to watch for. If you find your car unlocked with no sign of forced entry, or if the vehicle is missing and there’s no broken window or tow evidence, a relay attack is a prime suspect. Unexplained battery drains in your key fob, or the car responding when the fob is nowhere nearby, can also be early warning signs that someone has tampered with the wireless environment around your home or vehicle. Practical Steps You Can Take Right Now Prevention starts with small habit changes that greatly reduce your risk. The most immediate step is to stop leaving the fob next to an exterior door or in a coat pocket by the entrance. Criminals commonly position relay devices just outside front doors and windows to capture signals from fobs left on hallway tables. Keep your fob in a signal-blocking pouch (Faraday pouch) or a metal container when at home. These inexpensive items prevent radio waves from being transmitted and are widely available. If you don’t have a pouch, placing the key fob inside a microwave or a metal tin temporarily will also block the signal. Store spare fobs away from doors and windows — ideally in a central area of the house or inside a Faraday-lined container. Disable passive entry if your car allows it. Many vehicles offer a setting to turn off walk-up unlocking so the doors only unlock when you press the fob. This removes the always-on proximity behavior that relay attacks exploit. Similarly, when possible, configure your car to require the fob to be present and a button press on the fob for engine start rather than only relying on proximity detection. For overnight or extended parking, lock your car in a locked garage if available. A physical barrier — a door that must be opened to access the vehicle — adds a layer attackers must overcome and makes relay operations much more difficult in practice. Technology and Hardware Countermeasures Manufacturers and aftermarket vendors have introduced technical mitigations. Some carmakers are implementing motion- or sleep-sensing in fobs so the fob only transmits when it’s moving, drastically reducing the window of opportunity for relay attacks. Others use time-of-flight or angle-of-arrival radio techniques to estimate the physical distance between fob and vehicle more accurately, making it harder to spoof proximity. Aftermarket signal-blocking products, hardened steering-wheel locks, and wheel clamps still serve as effective physical deterrents. You can combine a Faraday pouch for daily storage with a visible mechanical deterrent such as a steering wheel lock when parking in public or in high-risk neighborhoods. Evidence shows opportunistic thieves are less likely to attempt thefts where the effort and time required are clearly higher. If you want a robust, manufacturer-level solution, check whether your carmaker offers a software update or an optional accessory that strengthens authentication. Some newer vehicles support phone-based digital keys that use secure elements and require biometric unlock on the phone — this stacks additional layers of security beyond raw radio proximity. Can a Locksmith Recover a Lost Digital Lock Passcode? Best Practices for Key Fob Handling and Car Storage Always carry the key fob on your person rather than leaving it at home during travel. Don’t stash spares in obvious places such as glove compartments, under the car, or in external boxes — thieves know where people hide keys. For families, distribute access carefully: issue digital keys with time-limited permissions if your vehicle supports it, rather than sharing physical fobs with everyone. When parking overnight on the street, choose well-lit and busy locations with camera coverage if possible. Public CCTV and visible neighbors act as deterrents. For short errands, keep windows up and doors locked; even if the vehicle remains unlocked, a thief is less likely to approach a car that sits in a visible, active environment. Vehicle Settings and Software Hygiene Just as you update your phone, keep your vehicle’s firmware and key fob software current. Many automakers release patches that adjust how fobs communicate or add new anti-tampering logic. Check your owner’s portal or dealer communications for recalls and security bulletins. If your car supports disabling passive entry, consider turning it off or using it selectively. Finally, avoid installing untrusted aftermarket modules that interact with the vehicle network, as poorly coded devices can introduce new vulnerabilities. How Dealers and Locksmiths Can Help A trusted dealer or certified automotive locksmith can assist in multiple ways. Professionals can check whether your vehicle has a passive-entry disable option and help configure it. They can evaluate key fob battery health and sensor alignment to reduce accidental transmissions. If you suspect your fob is compromised or malfunctioning, locksmiths can reprogram or replace the fob, and where possible, pair it with motion-sensing variants that minimize broadcast windows. At Brothers Locksmith , we specialize in automotive security services and can provide fast on-site diagnostics, key fob programming, and advice on the best physical and technical deterrents for your model. If a relay attack has occurred, our technicians can assist with immediate steps to secure replacement keys and recommend anti-theft upgrades. Advanced Detection and Forensics Detecting a relay attack after the fact can be challenging but not impossible. Some advanced systems and security services can scan for suspicious RF activity near your home or car. RF detectors can identify nearby devices operating on typical key fob frequencies. If you have reason to believe you’ve been targeted, a professional sweep can reveal anomalies that ordinary users won’t notice. For high-risk situations — fleets, high-value vehicles, or corporate car parks — consider installing monitoring solutions that log remote unlock requests and correlate them to time, location, and user credentials. Logging creates an audit trail which can be invaluable for investigations and insurance claims. Insurance, Liability, and Reporting Theft If your car is stolen via a relay attack, contact local law enforcement immediately and file an insurance claim with as much detail as possible. Document anomalies such as lack of forced entry, missing or damaged key fobs, and any RF detection logs if available. Some insurers are updating policy terms around keyless thefts, so consult your provider on coverage specifics and required safeguards. Keeping records of any security improvements — like Faraday pouches or steering locks — can demonstrate you took reasonable precautions. Community and Neighborhood Measures Prevention is easier together. Neighborhood watch groups and communities can spread awareness about relay attacks and encourage household practices like storing fobs centrally and using Faraday pouches. Businesses with parking lots can invest in CCTV and physical barriers or attendants who check vehicle access. Public awareness campaigns by local authorities or police can reduce the number of successful attacks simply by making thieves’ methods less effective through education. The Future: Where Vehicle Security Is Heading Vehicle security is evolving. Manufacturers are exploring multi-factor authentication for keyless systems, combining proximity with user biometrics or phone-based secure elements. Quantum-resistant cryptography and secure enclaves in smartphones could harden digital keys dramatically. Meanwhile, carmakers may more widely adopt distance-measurement techniques to validate a key’s true location. For owners, this means upgrades and retrofits will become available over time to retrofit older models with stronger authentication methods. When to Call a Professional If you notice unexplained unlocks, excessive key fob battery drain, or your car is missing without signs of forced entry, call a professional immediately. A qualified automotive locksmith can reprogram keys, assess whether your fob is leaking, install hardware anti-theft devices, and recommend best-in-class countermeasures for your car model. For immediate emergency response, Brothers Locksmith provides 24/7 automotive locksmith services, including on-site key replacement and security assessments. Practical Checklist: Quick Actions You Can Take Today Store your key fob in a Faraday pouch or metal container at home. Disable passive entry if your vehicle allows it; otherwise turn off auto-unlock features. Park in secured, well-lit, or attended areas whenever possible. Use a visible mechanical deterrent (steering wheel lock or wheel clamp) for added delay and deterrence. Keep vehicle and fob firmware updated and check with your dealer for security patches. Consider motion-sensing or low-broadcast fobs when replacing worn units. If targeted, document everything, notify police, and contact your insurer promptly.
