A break-in changes how your home feels the second you see the damaged door, missing property, or a window that will not lock. If you are asking whether to change locks after break in, the short answer is usually yes – but the right service may be rekeying, lock replacement, repair, or a combination of all three. The goal is not just to put a lock back on the door. It is to make sure nobody who gained access can come back.
First, get yourself and your family somewhere safe. Call 911 if there is any chance the intruder is still nearby or you need police assistance. Avoid touching disturbed areas until officers have had a chance to document the scene. Once the immediate emergency is under control, a trained mobile locksmith can secure the entry point at your home and help you make a clear decision about the locks.
Why You Should Change Locks After Break In
A burglar may have forced a door open, picked a lock, taken a spare key, or found a key that was left in an obvious place. You may never know exactly how access was gained. That uncertainty is why restoring security means more than replacing a broken piece of hardware.
If a key was stolen, lost during the incident, or possibly copied before the break-in, the old key can still work even when the lock looks fine. Rekeying changes the internal pins in an existing lock so old keys no longer operate it. It is often a smart, cost-conscious option when the lock is in good condition and you are comfortable keeping the same hardware.
Replacement is the better choice when a lock is bent, loose, drilled, cracked, poorly installed, or simply not providing the level of protection your home needs. A forced entry can also damage the strike plate, door frame, deadbolt opening, hinges, and latch. Installing a new lock without addressing that damage can leave the door vulnerable again.
For many Phoenix-area homes, the best answer is a rekey of every exterior lock plus repairs or upgrades at the door that was targeted. A locksmith can inspect the condition of each opening on-site instead of guessing based on what is visible from the outside.
Rekeying vs. Replacing Locks After a Break-In
Rekeying is fast and practical when the existing deadbolt and knob or lever lock are quality hardware, operate smoothly, and show no sign of tampering. The locksmith changes the key combination inside the cylinder and provides new keys. This prevents old house keys, stolen keys, contractor keys, or an unknown duplicate from opening that lock.
Changing the lock means installing new hardware or, in some cases, replacing the lock cylinder. It makes sense if the intruder damaged the lock, if the hardware is worn out, or if you want a stronger deadbolt, a different keyway, or a smart lock. It can also be the right move when your current locks are mismatched and you want a single key to work across the home.
There is a trade-off. Rekeying can save money and avoids replacing perfectly functional hardware. New locks offer an opportunity to improve durability, key control, and convenience. A professional should be honest about which option your door actually needs. You should not be sold a full replacement simply because a rekey is easier to overlook, and you should not rekey a lock that is too damaged to trust.
Secure the Door, Not Just the Lock
Deadbolts get most of the attention after a burglary, but the lock is only one part of the door system. A strong deadbolt installed in a weak frame can still fail under force. The door should close squarely, the latch and bolt should extend fully, and the strike plate should be firmly attached to solid framing.
After an attempted or successful forced entry, have the technician inspect the strike plate and the screws holding it in place. Longer screws that reach the wall framing can make a major difference. A split or soft door jamb may need repair before a new deadbolt is installed. If the door itself is cracked around the lock, replacing hardware alone will not fix the problem.
Do not forget sliding glass doors, garage-to-home doors, side gates, patio doors, and windows. Burglars often choose the least visible or least protected opening, not necessarily the front door. A technician can identify weak points and help prioritize the work if you need to manage a budget.
What to Do in the First 24 Hours
The hours after a break-in can feel chaotic. Focus on a few actions that protect your safety, documentation, and access to the home:
- File a police report and keep the report number for your insurance claim.
- Take photos of damaged doors, locks, frames, windows, and missing or disturbed property before repairs begin.
- Secure the entry point immediately, even if that means temporary boarding or an emergency lock repair.
- Rekey or replace exterior locks if keys are missing, access is uncertain, or the hardware was compromised.
- Update alarm, camera, garage-door, and smart-lock codes if devices or credentials may have been exposed.
If your wallet, mail, phone, computer, or documents were stolen, change passwords and monitor financial accounts as well. A house key paired with an ID showing your address creates a different level of risk than a key taken by itself. Tell the locksmith what was missing so the security plan fits the situation.
Consider Who Else May Have a Key
A break-in is also a good time to take inventory of key access. Former roommates, tenants, babysitters, house cleaners, maintenance workers, neighbors, relatives, and past contractors may have keys that you cannot account for. That does not mean they were involved. It means you deserve certainty about who can enter your home now.
Rekeying all exterior doors to a new key is usually simpler than chasing down every old copy. If you are a landlord or property manager, make sure the work follows your lease obligations and any applicable property requirements. For renters, contact the property owner or manager promptly, but do not leave a damaged entry unsecured while waiting for a decision.
When a Smart Lock or High-Security Lock Makes Sense
A break-in can be the moment homeowners decide to upgrade, but the most expensive option is not automatically the best one. Smart locks can be convenient for families that need temporary codes for guests, dog walkers, or service providers. They can also make it easier to remove access without collecting keys. However, they still need a properly secured door, good installation, and sensible account security.
High-security or restricted key systems can be valuable when you want tighter control over key duplication. They are often a strong fit for homes with frequent service access, rental properties, home offices, or valuable equipment. For other households, a quality deadbolt, reinforced strike plate, rekeyed cylinders, and better lighting may provide the most practical improvement.
The right approach depends on how the intruder entered, the condition of the door, who needs access, and what will help you feel secure when you lock up at night. A locksmith should explain those options in plain language, not pressure you into a package that does not match your home.
