After a break-in or attempted burglary, the locks on your doors are the first thing that needs attention — before insurance paperwork, before new curtains, before anything else. This guide walks Middlesex County homeowners through what to check before hiring someone to rekey locks after a break-in in 2026, and which upgrades are worth doing at the same visit.
- Rekey locks after a break-in within 24 hours — a picked or bumped cylinder stays compromised until it's changed.
- Apex Lock N Key rekeys standard deadbolts same-day across Middlesex County — Buy for immediate security.
- Forced or bent cylinders need extraction and replacement, not a basic rekey — Buy when there's visible damage.
- Electronic deadbolts remove the copied-key risk entirely — Consider if a spare key may have been taken.
- Skip a locksmith who won't put the work in writing — insurance claims need that paperwork.
Why this matters
A break-in changes what you know about your own locks: you no longer know who might have a key, an impression, or a photo of one. Rekeying resets that unknown back to zero without the cost of swapping every deadbolt on the house.
Apex Lock N Key handles this as a same-day emergency call, not a scheduled appointment three days out — that gap matters when the person who tried your door knows the attempt failed and might come back.
Insurance adjusters also ask for proof of security changes after a claim. A rekey invoice with a date on it is part of that file, not an afterthought.
Who this is for
This guide is for homeowners in Middlesex County, Massachusetts who just experienced a break-in, an attempted forced entry, or a lock that was picked, bumped, or damaged during the attempt — and now need to decide what to fix, in what order, before the next night falls.
What to look for in a rekey after a break-in
Same-day response, not next-week scheduling
A lock compromised tonight is still compromised tomorrow morning. Any locksmith worth calling after a break-in should be able to get a technician to your door the same day, not book you into next week's calendar.
Licensing and insurance you can verify
Someone handling the physical security of your home should be licensed and insured, and should say so without you having to ask twice. This isn't paperwork for its own sake — it's what protects you if something goes wrong during the job.
The rekey-vs-replace judgment call
A lock that was picked but not physically damaged can usually just be rekeyed. A lock that was pried, drilled, or has a bent strike plate needs the hardware replaced, not just the pins swapped. A technician should tell you which one you're dealing with before quoting a price.
Documentation for your insurance claim
If you're filing a claim, you need a dated invoice describing exactly what was changed. Ask upfront whether the locksmith provides this in writing — some hand you a receipt with no service detail, which won't satisfy an adjuster.
Upgrade options offered on the same visit
A break-in is the moment most homeowners actually consider an electronic deadbolt installation instead of another traditional cylinder. The best technicians can quote both on the spot instead of making you schedule a second visit.
Coordination across every entry point
A break-in attempt at the front door doesn't mean the back door, garage service door, and basement bulkhead are fine. If any of those share a spare key with the compromised lock, they need attention too.
Top picks: what to actually do after a break-in
The baseline fix: standard cylinder rekey
This reuses your existing deadbolt hardware and swaps the internal pins so old keys, copies, or impressions stop working. It's the right call when the lock itself wasn't physically damaged during the attempt — just tried. A standard single-cylinder rekey is a same-day job, typically finished in under an hour per door. Verdict: Buy for any lock that was targeted but not broken.
The forced-entry fix: broken key and cylinder extraction
When a lock was pried, drilled, or a key snapped off inside the cylinder during the attempt, rekeying alone won't fix it — the hardware itself is compromised. Broken key extraction service removes the damaged components and rebuilds the lock rather than just resetting the pins. If there's any visible prying damage on the door frame or strike plate, this is the fix you need, not a basic rekey. Verdict: Buy for anything showing forced-entry marks.
The proactive upgrade: electronic deadbolt install
If you suspect a spare key was taken — hidden under a mat, left with a dog walker, given to a contractor — a traditional rekey doesn't remove that risk entirely, because a new physical key can still be copied again. An electronic deadbolt installation replaces the key entirely with a code or app-based entry, which closes that loophole. Verdict: Consider if a spare key's whereabouts are unclear.
The whole-property fix: rekey every entry point at once
When one lock was targeted, the smart move is coordinating all door locks onto the same rekey visit rather than fixing one door and leaving the rest on old keys. This catches the garage service door, slider, and any secondary entrance that shares a key with the compromised lock. Verdict: Buy whenever more than one door uses the same key.
“If a lock was pried or drilled during the attempt, rekeying it just resets a broken part — the hardware needs replacing, not resetting.”
What to avoid
- DIY rekey kits bought online after a break-in. These require precise pin measurements and the right tools — a rushed job the same night often leaves the lock functional but weaker than before.
- Phone-only price quotes with no in-person confirmation. A locksmith who quotes a firm price before seeing the damaged lock is guessing, and guesses get revised upward once they're at your door.
- Fixing only the door that was hit. If the back door or garage entry uses the same key, leaving it untouched defeats the point of rekeying at all.

FAQ
What's the best way to rekey locks after a break-in?
The fastest reliable fix is a same-day cylinder rekey on any lock that was targeted, paired with extraction and replacement on any hardware that shows prying or drilling damage. A licensed locksmith can tell you which one applies within minutes of looking at the lock.
Is rekeying enough, or do I need new locks entirely?
Rekeying is enough when the lock wasn't physically damaged during the attempt — it resets the pins so old keys stop working. If the strike plate, cylinder, or frame was pried or bent, the hardware needs replacing, not just rekeying.
How much does it cost to rekey a house in Massachusetts in 2026?
Cost depends on the number of doors, the hardware brand, and whether any locks need full replacement versus a standard rekey. A locksmith quote page can walk through current 2026 pricing before you book a visit.
Should I rekey or replace after an attempted burglary where nothing was damaged?
Rekey. If the lock still functions and shows no prying, drilling, or cracking, changing the internal pins is enough to invalidate any key or copy that might exist.
How fast can a locksmith get to my house after a break-in?
A same-day emergency response is standard for break-in calls in 2026 — this isn't a scheduled-appointment situation, it's a same-day priority job.
Do I need to rekey every door or just the one that was forced?
Rekey every door that shares a key with the one that was forced. Leaving a back door or garage entry on the old key defeats the purpose if it opens with the same compromised key.
Will my insurance company ask for proof of rekeying?
Many adjusters request a dated invoice describing the security work done as part of a break-in claim. Ask your locksmith for written documentation at the time of service, not after the fact.
Is an electronic deadbolt better than a rekeyed traditional lock after a break-in?
An electronic deadbolt removes the risk of a physical key being copied again, which matters if you suspect a spare key was taken. A rekeyed traditional lock is faster and cheaper if the concern is limited to the lock that was targeted.
One last thing
The detail most homeowners miss in 2026 isn't the front door — it's the secondary entry points that share a key with it. A garage service door or a sliding door lock left untouched after a rekey is still opened by any key or copy that existed before the break-in, which makes a single-door fix incomplete more often than not.
