Lock Replacement After a Burglary: 4 Checks Before You Buy Parts
If a break-in damaged your lock, make sure you are safe, call the police, and photograph everything before you touch it. Then check the cylinder, deadbolt, strike plate, and frame. Rekey or swap parts when only the internal lock is hurt. Replace the lock and call a locksmith when the bolt, jamb, or hinges are damaged. We at Progressive Locksmith Cerrajero help with all of it.
TL;DR:
Rekey the cylinder only when it remains undamaged and the bolt, latch, jamb, and hinges are intact; drilled pins or a broken key require replacement.
A bent bolt, split jamb, or loose hinges requires a locksmith and possibly carpentry, because replacing the lock alone leaves the entry point weak.
For protection, choose a Grade 1 deadbolt and reinforce its strike plate with hardened screws; weak anchoring can defeat even a strong lock.
Most homeowners spend $60 to $350 for replacement, while emergency or after hours calls can add $50 to $150; daytime appointments can avoid the surcharge.
For insurance claims, keep every receipt and technician note, and confirm whether your insurer requires a police report before repairs begin.

How to assess the damage: a quick diagnostic you can do now
Start outside, then work inward. Look closely before you replace anything, because the visible damage often points to a hidden problem in the door frame.
Exterior check: Look for bent metal, pry marks, and splintered wood around the jamb and strike plate.
Key test: Insert your key and turn it. Note if it sticks, spins freely, or won’t go in.
Knob and deadbolt test: Work each one and watch the latch and bolt move. Slow, rough, or uneven movement means internal damage.
Frame and hinge check: Look for pulled screws, loose hinges, or a split jamb. These mean the door itself is compromised.
Treat the whole entry point as one system. Security experts note that a high-security cylinder does little good when the door, frame, hinges, or strike plate are weak or damaged. A shiny new lock on a cracked frame will fail the same way the old one did.
Pro Tip: Photograph every angle before you adjust anything. Your insurer will want the original damage, not your repairs.
Which parts typically need replacing after forced entry
Forced entry usually hits one or two parts hard and leaves the rest alone. Knowing which is which keeps you from overspending or under-fixing.
Cylinder or core: If it works and shows no physical damage, rekeying is enough. If a key broke inside or the pins were drilled, the cylinder must be swapped. Our guide on a broken key in a lock covers when extraction is safe to try.
Deadbolt: A sheared or bent bolt means a new deadbolt. Don’t reuse it.
Latch and strike plate: Short screws are the usual weak spot. Consumer Reports lab testing found many locks fail kick-in tests because of weak strike-plate anchoring, and a reinforced strike plate improves resistance.
Hinges and jamb: A split jamb or loose hinges need carpentry plus new hardware before any lock goes back on.
If you’re weighing rekeying against full replacement, this partner article on rekeying versus replacing locks offers another useful perspective.
Where to buy replacement locks and how to pick the right one
You have several sourcing options: a local locksmith, a big-box hardware store, a specialty online retailer, or an architectural salvage yard for older finishes. A locksmith is the best choice for fit and security because the part arrives matched to your door.
Before you buy, measure carefully:
Backset: the distance from the door edge to the center of the bore hole.
Door thickness: most residential doors are standard, but check yours.
Bore-hole diameter: the main hole the lock sits in.
Handing: which way the door swings, since some locks are handed.
Finish: match your existing hardware so it looks consistent.
Then choose by grade. BHMA’s Certified SecureHome program uses ANSI/BHMA standards A156.39 for locksets and A156.40 for deadbolts to rate performance. Match the grade to your risk and to how strong your door and frame really are. Our explainer on deadbolt grades walks through the differences.
DIY repair vs hiring a locksmith: clear rules for choosing
DIY works when the frame is intact and the job is a straightforward knob or deadbolt swap. You’ll need screwdrivers, a drill, a chisel, and the patience to measure twice. Bob Vila’s step-by-step guide shows the repeatable process.
Call a locksmith when any of these apply:
The deadbolt, jamb, or hinges are damaged.
A broken key needs extraction.
You’re installing a smart lock that needs programming.
You want a technician’s notes and receipt as proof for insurance.
A DIY install on a weakened frame can leave you with a lock that looks new and fails just as fast. It can also muddy your claim if nobody documented the work.
Pro Tip: If the damage isn’t urgent, schedule your visit during business hours. After-hours calls usually carry a surcharge.
Typical costs and insurance: what to expect and how to document a claim
Angi reports that most homeowners spend between $60 and $350 to replace a lock, and that emergency or after-hours calls can add $50–$150. Basic parts often run $20–$80, while higher-end deadbolts and smart locks cost more. Locksmith labor and service fees vary depending on the job and provider.
A simple decision rule: compare the repair cost with the replacement cost, and replace the lock if repair is not worthwhile.
Most homeowners spend $60 to $350 to replace a lock, according to Angi’s cost data. Your final number depends on the lock grade, the labor, and what time you call.
To protect your claim:
Take photos of all damage before any repair.
File a police report if your insurer requires one.
Keep every receipt and technician note.
Temporary fixes to secure the door while you arrange replacement
You may need a few hours or a few days before the permanent fix. These steps reduce your risk in the meantime:
Lock every other entry point and let a neighbor know what happened.
Keep valuables out of sight, and avoid sleeping near a compromised door if you can.
Swap the short strike-plate screws for 3-inch hardened screws that reach the framing.
Tighten loose hinge screws.
Fit a temporary deadbolt or slide bolt if one is compatible with your door.
Pro Tip: Never block your own exit. Anything that stops you from leaving fast in a fire can also complicate your insurance.
A concise step-by-step checklist to finish the job
Work through these in order, and use the timing as a guide.
Immediately: Photograph and document the damage.
Immediately: Call the police if entry occurred.
Within hours: Secure the door with temporary fixes.
Soon: Decide whether to rekey, repair, or replace.
Afterward: Buy parts or book a locksmith.
Afterward: Keep receipts and update your insurance and records.
Once the lock is done, run through our home security audit checklist to catch other weak points.
Why a professional assessment often beats DIY after forced entry
We assess the frame and strike plate as well as the lock body. A quick part swap on a weak frame often gets kicked in the same way again. A locksmith can check the whole entry point, install suitable parts, and provide documentation. Our own guide on how frame strength shapes your lock choice explains the logic.

FAQ
What is the hardest lock to break into?
No lock is unbreakable, but Grade 1 deadbolts are the strongest residential option. Locksmith Ledger reports they’re tested with 1,350 pounds of force and at least 400,000 cycles. Pair one with a reinforced frame to strengthen the entry point.
How much does it cost to replace a broken lock?
Most homeowners pay between $60 and $350, according to Angi. Emergency calls cost more than scheduled visits. The grade of lock and the labor involved also change the total.
Can you just replace the lock cylinder?
Yes, if only the cylinder is damaged and the deadbolt, latch, and frame are intact. If the bolt is bent or the jamb is split, replacing the cylinder alone won’t restore security. A locksmith can tell you which case you have.
What is the best door lock to prevent break-ins?
Choose an ANSI/BHMA Grade 1 deadbolt with the BHMA Certified SecureHome label, then reinforce the strike plate with longer, hardened screws. LockLab notes this is often the most cost-effective upgrade, because many failures come from weak anchoring, not the lock.
