Residential Locksmith Guide
Residential locksmith needs generally fall into a few categories: deciding between rekeying and replacing locks, handling a home lockout, knowing when to rekey, and addressing deadbolt problems or a broken key stuck in a lock. This guide covers each of these situations and links to a detailed article on each.

Rekey or Replace?
Rekeying changes which keys operate an existing lock without replacing the hardware, making sense when the lock itself is in good condition and the concern is who has a working key. Replacement is the better fit when the lock is worn, damaged, or you want different features. Rekeying applies to locks compatible with that process; not every lock can be rekeyed, so confirming compatibility with your specific hardware is part of this decision.
See Should You Rekey or Replace Your Locks? for how to decide between them.

Locked Out of Your House
If you’re locked out, contact anyone authorized who may have a spare key or legitimate access and avoid forcing or attempting to bypass the lock. A qualified locksmith can evaluate an appropriate authorized-entry method.
See What to Do When Locked Out of Your House for the fuller immediate steps.

When to Rekey Your Locks
Common situations that call for rekeying include moving into a new home, losing keys, a change in who should have access after a relationship or living situation changes, or after a contractor or service provider has had temporary access. These are all about resetting who has a working key rather than addressing a mechanical problem with the lock itself.
See When Should Home Locks Be Rekeyed? for these situations in more detail.

Deadbolt Problems
Some lock or deadbolt problems may involve alignment, wear or maintenance, while damaged hardware may require professional repair or replacement. Avoid forcing a lock that is binding or damaged.
See Deadbolt Problems and Repair for how to diagnose these issues.
A Broken Key in a Lock
If a key breaks off inside a lock, avoid trying to remove it with household tools, since this risks pushing the fragment deeper or damaging the lock. A locksmith uses specialized tools to extract the broken piece and can typically cut a replacement if a working spare is available.
See Broken House Key in Lock for what to do and what to avoid.
