Should You Change Locks After a House Cleaner or Repairman Visit?

December 3, 2025

There’s something oddly unsettling about realizing a stranger—no matter how polite or professional—has walked through your home while you weren’t there. Maybe it was your house cleaner, an appliance repair technician, the plumber, or the painter. And now, the thought hits you:
“Should I change my locks after this visit?”

This is a question homeowners don’t usually ask out loud, but they think about it more often than you’d imagine. As locksmiths, we’ve seen everything from harmless situations to full-blown security risks that started with a simple service visit. That’s why this topic matters—because your peace of mind starts with the doors that protect your home.

How to Tell If Your Home Is Being Targeted for a Break-In

Why letting someone into your home can become a security risk—even unintentionally

Most service workers are honest people simply doing their jobs. But access is access. Anyone inside your home can observe how your locks work, whether your backdoor fully latches, or whether your spare key bowl is sitting on the kitchen counter.
Even if they never misuse that information, your home’s exposure increases, and that alone raises the question of whether your locks need a security refresh.

Locksmiths like Brothers Locksmith often get calls from people who say things like:

“The contractor was the last person with access before something went missing.”
“My cleaner left on good terms, but I don’t want her old employee having the spare key.”
“A different technician showed up than the one the company promised.”

Security concerns don’t always come from distrust—they come from being practical.

Do professionals have access to your keys without you realizing?

This surprises many homeowners, but yes—there are subtle ways key access can happen:

1. Keys can be briefly borrowed or copied in under 2 minutes

A quick photo. A fast duplication. A key impression made using a soft material.
These things don’t require your physical key to be gone for long.

2. Some cleaning staff operate in teams

You may trust the main cleaner, but today’s shift might include someone you’ve never met.

3. Unvetted third-party contractors

If a plumbing company outsources a job to a freelancer, you might not know who actually entered your home.

You’re not being paranoid—you’re simply acknowledging real-world security gaps.

When it is smart to change or rekey your locks

You don’t need to change your locks after every visit, but certain situations absolutely warrant it.
Here are the scenarios locksmiths see most often:

When you handed over a physical key

Even if it was temporary, a key can be copied in minutes.
In many U.S. states, there’s no law preventing someone from duplicating a key you lent them.

When a service provider worked alone inside the house

You were at work or running errands. They had unrestricted access. Changing or rekeying afterward adds peace of mind.

If you noticed someone checking windows, back doors, or unusual areas

Even curious glances matter. Anything that feels “off” should be taken seriously.

When a company rotates staff frequently

If you never know which cleaner or technician will show up, rekeying once a year is a smart habit.

If you recently fired a cleaner or ended a contract

Breakups—personal or professional—can turn ugly fast. Rekeying protects you regardless of emotions.

Should you rekey or replace? (Insider locksmith advice)

Many homeowners assume they need an entirely new lock, but that’s not always the case.

Rekeying (recommended in most cases)

A locksmith changes the internal pins so old keys stop working.
It’s affordable, fast, and restores full control over who has access.

Replacing the lock

This is necessary when:

Your current lock is low-quality or outdated
You want to upgrade to smart locks
The lock shows signs of tampering
You want higher-grade security for long-term safety

Brothers Locksmith often recommends rekeying unless the lock is already worn or poorly built. No point keeping a weak lock just because the key works.

Smart locks: Do they eliminate this problem?

Smart locks don’t use physical keys—so no one can copy anything.
But there are other considerations:

Many smart locks log who enters and when

Some allow temporary access codes for cleaners or repairmen

You can delete or change those codes after every visit

Some can auto-lock, removing the “I forgot to lock the door” problem

A lot of homeowners who switch to smart locks with code-based access say they feel much safer giving temporary entry.

And if you’re not sure which smart lock works best for your home layout or lifestyle, Brothers Locksmith can recommend ones that actually hold up.

The hidden factor most homeowners forget: your spare keys

Even if you never gave someone a key, think about where your extras are:

Junk drawer
Key bowl in the kitchen
Hook near the entryway
A drawer in your study

That “secret place” near the front porch (which is never as secret as we think)

Visitors notice things without trying to.
A service worker might not care—but someone in their company or someone who overhears information might.

Security breaches often start with very small oversights.

What to do if your instinct says something felt “off”

If the visit left you uneasy—even if you can’t explain why—trust that feeling.
Professionals who work security know that intuition is one of the most accurate early warnings.

Here’s what locksmiths usually recommend:

Rekey the locks (most affordable peace-of-mind option)
Check the deadbolt alignment
Inspect for any signs of lock tampering
Consider upgrading to a pick-resistant or smart lock
Doing this proactively is always easier than dealing with a break-in later.

So, should you change your locks? Here’s the simplest rule.

If someone outside your household has had unsupervised or repeated access to your home, it’s reasonable—sometimes necessary—to update your locks.

It’s not about accusing anyone.
It’s about maintaining the safety of the place you sleep.

Brothers Locksmith always tells customers:

“Locks protect your home, but rekeying protects your peace of mind.”

And honestly, that peace of mind is priceless.

When to call a professional locksmith

Call a locksmith if:

You handed someone a key
You ended a cleaning or repair service
You felt uneasy after a visit
Your locks are old and due for an upgrade
You’re considering smart lock options
You want temporary access codes for cleaners or guests

A quick rekeying or a well-chosen lock upgrade can close a security gap you didn’t even realize existed.

Brothers Locksmith can help assess your doors, your locks, and your access points—and guide you toward the safest, most practical solution.

How to Secure Basement Doors and Windows

By Ghulam Mustafa • August 1, 2026

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.
