Lock replacement
When the lock itself is the problem, replace it.
- Matched to your door's prep
- Grades explained before you choose
- Price confirmed first
A cylinder that grinds, a deadbolt that's been kicked, a handle hanging loose: these call for a lock change, not just new keys. The tech removes the old hardware, checks the door's bore and backset, and fits a lock replacement that suits the door and how you use it, for homes and businesses in Los Angeles County.
If the lock still works and you only need old keys retired, rekeying is the lighter option. Want to move up to keypad or app control? That's covered under deadbolt and smart lock installation.

Lock grades, explained
ANSI/BHMA Grade 1
The highest grade in the standard, aimed at heavy commercial use. A strong choice for exposed or high-traffic doors.
Grade 2
A common residential grade, also used in light commercial settings. Suits most home entry doors.
Grade 3
The minimum residential grade in the standard. Fine for interior doors, less suited to a main entry.
Signs it's time for a lock change
Replace rather than repair when:
- The cylinder spins or grindsInternal parts are worn or broken.
- The lock was damaged in a break-inBent bolts and cracked housings can't be relied on to hold again.
- Rust or corrosion is setting inCommon on exterior hardware exposed to sprinklers and coastal air.
- Keys are hard to getOlder or discontinued locks can be difficult to rekey or duplicate.
- You want a stronger gradeMoving a main entry from a basic lock to a sturdier deadbolt.
Safety first. If a lock fails while the door is locked, don't pull screws or force the bolt with a screwdriver. You can bend the bolt and turn a simple replacement into a drilled lock.
