Safety
If locked out of a home with a child, elderly person, or pet inside and there is a risk of heat, cold, or medical distress, call emergency services before calling a locksmith. Never attempt to force a deadbolt or kick a door; this can cause injury and often turns a simple lock repair into a full door and frame replacement. Do not climb to second-floor windows or use ladders alone to gain entry; falls are a leading cause of lockout injuries. If a key snaps off inside a lock, stop turning it and do not dig with tools; deeper breakage makes extraction harder. For a car lockout with an engine running or a pet inside, contact roadside assistance or emergency services first. Verify the identity of any technician who arrives and confirm the quoted price before work begins.
Before the visit
Have the property address and a clear description of the door and lock type ready, such as a deadbolt, mortise lock, or knob set. If it is a vehicle issue, note the make, model, and year, and mention whether a fob key replacement or locksmith program key fob service is needed. Be ready to show proof of ID or residency when the technician arrives so keys can be made or locks opened legally. Mention any recent events, such as a break-in attempt, a jammed key, or a lock that has been sticking for weeks. Ask whether the situation needs lock repair or a full replace deadbolt decision, since parts and pricing differ. Keep a phone nearby with a charged battery in case the technician needs photos or directions.
Repair vs replace
A deadbolt or knob lock sticks, grinds, or requires jiggling the key but still opens reliably. A key turns but the latch does not extend or retract fully, a common mortise locksmith repair. A key has snapped inside the cylinder and the broken piece can potentially be extracted. The lock mechanism is loose, the faceplate is shifting, or screws keep working their way out. A rekey is enough after moving in or losing a single copy of a key. Locksmith key fob programming can fix a fob that stopped syncing after a battery change.
When to replace
The deadbolt is rusted, corroded, or has been forced during a break-in attempt. The lock is an old low-security model and a deadbolt installation or upgrade to a higher-grade cylinder is wanted. The key replacement option no longer works because the cylinder is worn beyond rekeying. A mortise lock body is cracked or the mechanism is seized and parts are no longer available. After a tenant turnover, divorce, or lost keys where full replacement offers more peace of mind than rekeying. A vehicle fob is physically damaged or water-logged and a fob key replacement is more reliable than repair.
Common issues
| Symptom | Likely causes | Safe check | Stop when |
|---|---|---|---|
| Key turns but the deadbolt will not extend or retract | Misaligned strike plate, worn deadbolt latch, or a shifted door frame | Close the door slowly and watch where the bolt meets the strike plate; check that hinge screws are tight | The bolt is completely frozen, metal fragments are visible, or the door frame is cracked |
| Key is stuck or hard to remove from the lock | Dry or dirty cylinder, worn key, or damaged pins inside the lock | Try a spare key and apply a small amount of graphite or lock-specific lubricant, never oil-based sprays | The key will not budge at all, or it feels like it may snap off inside the cylinder |
| Key broken off inside the lock | Worn or bent key, frozen cylinder, or forcing a lock that was already sticking | Stop using the lock, leave the broken piece visible, and confirm a spare key exists for another entry point | The broken piece has been pushed deeper into the cylinder or extraction tools are not on hand |
| Car key fob stopped working | Dead fob battery, lost programming, or a damaged vehicle receiver | Replace the fob battery with the correct type and try the physical backup key to confirm the vehicle starts | The vehicle does not recognize the fob after a fresh battery, or the fob casing is cracked and water-damaged |
| Lock spins freely without engaging | Broken tailpiece, disconnected set screw, or internal mechanism failure in a mortise lock | Check whether the knob or cylinder spins on both sides and confirm the door can still be secured another way | The door cannot be locked at all and the property will be left unattended overnight |
| Locked out of home or vehicle | Keys locked inside, lost keys, or a latch that snapped shut behind an auto-locking door | Check all entry points, spare key locations, and whether a roommate or family member can bring a key | A child, pet, or vulnerable person is inside, or a key is visibly dangling in the ignition of a running vehicle |
| Deadbolt misaligned with the strike plate after settling or humidity | Seasonal wood swelling, hinge wear, or foundation movement shifting the door | Test the bolt with the door open; if it works smoothly open, alignment rather than the lock itself is the issue | The door no longer closes flush, hinges are pulling out, or forcing the bolt has bent the latch |
