How to Rekey Your House After a Break-In or Theft

August 6, 2025

A break-in is more than just a physical violation—it leaves emotional scars and questions about how secure your home truly is. After experiencing theft or any unauthorized entry, one of the most crucial steps you can take to restore safety and peace of mind is to rekey your locks. But what does that mean, how do you do it, and when should you consider replacing instead of rekeying? Let’s break down everything you need to know, step-by-step.


Top 10 Home Security Tips Recommended by Locksmiths


Why Rekeying Is Critical After a Break-In

If someone has had access to your keys—or forced entry through your door—your current locks can no longer be trusted. Even if they didn’t steal your keys, you can't rule out the possibility they duplicated them. Rekeying immediately ensures the old keys no longer work, and only new ones in your possession will provide access. It’s one of the fastest and most affordable ways to regain control of your home’s security.


What Does Rekeying Mean?

Rekeying a lock means changing the internal configuration (the pins inside the lock cylinder) so that it only works with a new key. You keep the same lock hardware on the door—but the old key won’t fit anymore. This is a less expensive alternative to replacing all your locks and just as secure when done correctly.


Should You Rekey or Replace the Locks?

Here’s a quick way to decide:

Rekey your locks if:

  • The locks weren’t physically damaged during the break-in.
  • You want a budget-friendly option.
  • You want all doors to use a single key (keyed alike).
  • Your locks are still high-quality or fairly new.


Replace the locks if:

  • The locks were broken, drilled, or picked.
  • You want to upgrade to more secure or smart locks.
  • The current locks are old, rusty, or unreliable.
  • You’re unsure how many people had copies of the old keys.


How to Rekey Your Locks (DIY or Pro)

You have two options: do it yourself using a rekeying kit, or hire a professional locksmith. Let’s go through both.

Option 1: DIY Rekeying (For Standard Pin Locks)

If you’re comfortable with tools and your locks are from a brand like Kwikset or Schlage, you can buy a rekeying kit from your local hardware store. Here's what the process looks like:

What You’ll Need:

  • Rekeying kit (brand-specific)
  • Original key and new key
  • Plug follower tool
  • Tweezers or a pick tool
  • Screwdriver

Steps:

  1. Remove the doorknob or deadbolt using a screwdriver.
  2. Take out the lock cylinder from the housing.
  3. Use the original key to turn the plug, then push the plug out using the plug follower.
  4. Remove the old pins from the plug.
  5. Insert new pins (they’re color/number coded to match the new key).
  6. Reinsert the plug and reassemble the lock.
  7. Test the new key before reinstalling everything.

Note: If you’re uncomfortable doing this or if you have a smart lock, keypad lock, or high-security lock, it's best to call a locksmith.

Option 2: Hiring a Locksmith

A locksmith can rekey most locks within 15–30 minutes, often for around $20–$50 per lock (plus a service fee). They’ll:

  • Rekey all your locks to work with a single new key (if requested).
  • Inspect locks for damage.
  • Upgrade lock hardware if needed.
  • Install additional reinforcements like strike plates or smart locks.

Bonus: Locksmiths ensure there are no vulnerabilities left behind that you might miss.


Rekeying All Entry Points

After a break-in, don’t just rekey the front door. Burglars often check for weak points:

  • Front and back doors
  • Garage entry doors
  • Side entrances
  • Sliding doors (install additional locks or bars)
  • Windows (install window locks if none exist)
  • Mailboxes or sheds (if locks were compromised)


5 Signs It’s Time to Replace Your Home Door Locks


Consider Upgrading to Smart or High-Security Locks

After a break-in, many homeowners realize it’s time to take security more seriously. Rekeying is a great first step, but it might also be time to consider:

  • Smart locks with remote control, activity logs, and auto-lock features
  • High-security locks with drill/pick resistance and patented keys
  • Keyless entry systems to eliminate physical keys altogether

These upgrades add layers of protection and give you greater control over who enters your space.


Other Security Steps to Take After Rekeying

Securing your home isn’t just about the locks. After rekeying, take the opportunity to:

  1. Install motion-activated lighting around entry points.
  2. Trim bushes and trees to eliminate hiding spots.
  3. Install a doorbell camera or full home security system.
  4. Reinforce strike plates with longer screws and metal plates.
  5. Notify neighbors about the break-in so they stay alert.
  6. Get new spare keys but only give them to trusted individuals.


How Long Does Rekeying Take?

  • DIY rekeying: 20–60 minutes per lock (if you’re handy)
  • Professional locksmith: 15–30 minutes per lock

For 3–4 doors, a locksmith can have you fully rekeyed in under two hours.


How Much Does Rekeying Cost?

DIY kits: $10–$20 per kit (usually rekeys up to 6 locks)
Locksmith service:

  • $20–$50 per lock
  • $75–$150 service call
  • Discounts often available for multiple locks

Still far cheaper than replacing all your hardware.


Final Thoughts: Rekeying Is Empowering

A break-in can make you feel vulnerable and shaken, but rekeying is a quick, smart, and affordable way to reclaim your sense of safety. Whether you choose to DIY or hire a pro, don’t delay this step. Your home should be your safe place—start by making sure you're the only one with access.

Securing basement doors and windows is essential because these entry points are often less visible, less frequently used, and more likely to be overlooked than the main entrances of a home. Reinforcing locks, maintaining the surrounding frames, improving lighting, and regularly inspecting basement access points can significantly reduce the risk of unauthorized entry. Many homeowners spend time securing their front and back doors but pay little attention to the basement. Because basement entrances are often hidden behind landscaping, fences, or below ground level, they can provide the privacy that opportunistic burglars look for. Whether your basement includes exterior doors, hopper windows, sliding windows, or egress windows, treating these access points with the same level of security as the rest of your home is an important part of protecting your property. Quick Answer To secure basement doors and windows, install quality locks, reinforce the door frame, ensure windows close and lock properly, improve outdoor lighting, trim nearby landscaping, and inspect all basement entry points regularly. Keeping these areas well maintained and visible helps reduce vulnerabilities and strengthens your home's overall security. Why Are Basement Entry Points More Vulnerable? Basement entrances often receive less attention than front or back doors because they are used less frequently. Many are located at the side or rear of the property, partially hidden from neighboring homes and street traffic. This additional privacy can make them more appealing to someone attempting unauthorized access. Because homeowners may not inspect these areas regularly, worn hardware, loose locks, or damaged frames can remain unnoticed for long periods. Giving basement doors and windows the same attention as other exterior entry points helps eliminate these common weaknesses. How Important Is a Secure Basement Door? If your basement has an exterior door, it should provide the same level of protection as your front entrance. A quality deadbolt , durable lock cylinder , reinforced strike plate , and solid door frame all contribute to stronger security. The door should close tightly without excessive gaps and allow the deadbolt to extend fully into the strike plate. If the door sticks, sags, or requires extra force to lock, correcting the alignment helps both security and long-term lock performance. A secure basement door forms one of the most important barriers protecting the rest of your home. Why Should Basement Windows Be Inspected Regularly? Basement windows are often smaller than standard windows, but they can still provide access if they are damaged or left unsecured. Over time, window locks may wear out, frames can deteriorate, and windows may no longer close completely because of foundation movement or moisture. Testing every basement window periodically ensures the locking hardware operates properly and that there are no visible gaps that could compromise security. Regular inspections also allow homeowners to identify water damage or structural problems before they become more serious. Can Door Reinforcement Improve Basement Security? Absolutely. Even a high-quality lock provides limited protection if the surrounding door frame is weak. During a forced-entry attempt, the frame and strike plate absorb much of the impact. Reinforcing these components improves the door's ability to withstand force while allowing the deadbolt to perform as intended. A reinforced basement entrance also reduces long-term wear by maintaining proper alignment between the door and locking hardware. Why Does Outdoor Lighting Matter Around Basement Entrances? Basement entrances often remain darker than other areas around the home. Without adequate lighting, someone can approach the door or window with a reduced chance of being noticed. Motion-activated lighting immediately increases visibility whenever movement is detected, making concealed access more difficult. Installing lighting near basement stairwells, exterior doors, and window wells also improves safety for homeowners accessing these areas after dark. Good visibility is one of the simplest and most effective security improvements. Can Landscaping Affect Basement Security? Yes. Dense shrubs, tall plants, or overgrown vegetation around basement windows and doors may provide cover for someone attempting to enter the home unnoticed. Keeping landscaping neatly trimmed improves visibility while reducing hiding places around vulnerable entry points. Clear sightlines also make it easier for neighbors or passing pedestrians to notice suspicious activity near the basement. Balancing privacy with visibility helps create a more secure property. Why Is Proper Lock Maintenance Important? Locks that are rarely used often receive the least maintenance. Dust, moisture, and dirt can accumulate inside the keyway , affecting the smooth movement of internal pins and springs. A lock that feels stiff today may eventually become difficult to operate if ignored. Cleaning and lubricating basement door locks with an appropriate dry lubricant helps extend their lifespan while ensuring reliable performance whenever the entrance is used. Routine maintenance also allows homeowners to identify worn components before they fail. Should Egress Windows Remain Secure? Yes, but they must also remain functional for emergencies. Basement egress windows are designed to provide a safe exit during fires or other emergencies. While they should always be secured against unauthorized entry, any security measures used should still allow occupants to open the window quickly from inside when necessary. Regular testing ensures both the locking hardware and emergency release function correctly. Balancing security with emergency accessibility is especially important for finished basements used as living spaces or bedrooms. Can Smart Security Devices Help Protect Basement Entrances? Smart home technology can provide additional protection for basement access points. Security cameras positioned near basement doors or stairwells allow homeowners to monitor activity remotely. Motion sensors and smart lighting systems can also provide alerts whenever movement is detected around these less frequently used areas. These systems work best when combined with strong physical security such as reinforced doors, quality locks, and properly maintained windows. Technology should enhance—not replace—solid mechanical security. When Should You Have a Locksmith Inspect Basement Entry Points? If your basement doors or windows have not been inspected in several years, a professional evaluation can identify issues that may not be immediately visible. A locksmith can examine the deadbolt , lock cylinder , door frame , strike plate , hinges, and overall door alignment to ensure the entrance provides dependable protection. They can also recommend repairs or adjustments that improve security without necessarily replacing existing hardware. Professional inspections are especially valuable after renovations, foundation movement, or signs of attempted forced entry. Frequently Asked Questions Are basement doors easier to break into? They can be if they have outdated locks, weak door frames, poor lighting, or are hidden from public view. Proper reinforcement greatly improves security. Should basement windows always be locked? Yes. Every basement window should remain securely locked whenever it is not being used for ventilation or emergency access. Can landscaping affect basement security? Yes. Overgrown shrubs and dense vegetation can provide hiding places near basement doors and windows, making unauthorized access easier to conceal. Do basement locks require maintenance? Absolutely. Cleaning and lubricating locks periodically helps maintain smooth operation and extends the life of the locking mechanism. Are security cameras useful for basement entrances? Yes. Cameras help monitor areas that are less frequently used and may discourage suspicious activity around basement doors and windows. When should I call a locksmith? You should contact a locksmith if your basement door becomes difficult to lock, the frame shows signs of damage, the hardware feels loose, or you want a professional security inspection. Final Thoughts on How to Secure Basement Doors and Windows Basement doors and windows deserve the same level of protection as every other exterior entrance. Reinforced door frames , quality deadbolts , secure window locks, proper lighting, and regular maintenance all help reduce vulnerabilities that could otherwise be overlooked. Creating a secure basement is about combining strong physical security with consistent inspections and preventative maintenance. By identifying small problems early and ensuring every basement entry point remains in good condition, homeowners can improve the overall security of their property while gaining greater peace of mind.
