New keys without replacing a good lock
Rekey Home Locks in Los Angeles
When the hardware is compatible and working properly, rekeying can change who has access without changing the whole lock.
Call or text 626-399-7156 with the lock brands, number of cylinders, and whether you want compatible locks keyed alike.
Keep the lock and change the working key
Rekeying changes the internal keying of a serviceable lock cylinder. A new key is prepared to operate the lock, and the previous key no longer works. The existing lock body remains on the door, making this a distinct service from hardware replacement.
Homeowners often request rekeying after moving, when an old key is unaccounted for, or when several compatible locks should use one new key. The lock type, keyway, cylinder design, and condition determine whether rekeying is possible. Different brands or incompatible cylinders may not be keyed together.
If a lock is cracked, badly worn, loose, or failing to latch, changing the keying will not correct the mechanical problem. In that case, repair or replacement may be the more practical recommendation after the hardware is examined.
Rekey versus lock change
Rekey means new keys and the same lock. A lock change means the hardware comes off and a different lock goes on. If you want a new finish, a different function, or the old lock is too worn to keep, use lock change and replacement. If you only need the keys to change, stay here.
Good reasons to consider rekeying
Rekeying is most useful when you want different keys and the current hardware is worth keeping.
You recently moved
Change the working keys when you do not know how many copies were issued to previous occupants.
A key is unaccounted for
Retire an old key without replacing compatible locks that remain in good working condition.
The lock has a mechanical problem
Sticking, binding, looseness, or latch trouble calls for repair evaluation rather than a keying change alone.
You want new hardware
Choose lock replacement when the goal is a different style, finish, function, or lock body.
How residential rekeying is arranged
Lock details and keying goals are reviewed before work begins at the property.
- 1
Count and identify the locks
Note each cylinder, visible brand, available working key, and which doors you want included.
- 2
Discuss compatibility and keying
Explain whether each lock needs its own key or whether compatible cylinders should operate on one key.
- 3
Rekey serviceable cylinders
When the hardware is suitable, internal keying is changed and the new keys are checked at the doors.
A practical approach to key control
The service focuses on compatible cylinders, usable hardware, and the keys you want to retire.
Serviceable hardware can stay
A compatible lock does not have to be discarded solely because you need different keys.
Compatibility is considered first
Brand, keyway, cylinder type, and condition are reviewed before locks are grouped on one key.
Keying goals are clearly defined
You can explain which previous keys should stop working and which doors you want the new keys to open.
Mechanical issues are not overlooked
If the hardware is failing, repair or replacement can be discussed instead of treating rekeying as a fix.

Lock rekeying questions
What changes during a lock rekey?
The locksmith changes the cylinder's internal keying so it responds to a new key. Compatible, serviceable lock hardware stays on the door, while the previous key is intended to stop operating that cylinder.
Can all of my doors use the same new key?
Sometimes. The cylinders generally need compatible keyways and designs, and each lock must be in usable condition. Locks from different systems may require separate keys or different hardware.
Is rekeying appropriate after moving into a home?
It can be a practical choice when you want prior keys to stop working and the existing locks are compatible and serviceable. If you rent, obtain any required property approval before authorizing changes.
Can a damaged or sticking lock simply be rekeyed?
Rekeying changes key access; it does not fix worn parts, alignment trouble, a loose body, or a failing latch. A malfunctioning lock should be evaluated for repair or replacement.
Do I need an existing working key for rekeying?
A working key can be useful, but requirements vary with the cylinder and its condition. Explain whether you have a current key when you call so the specific lock can be discussed.
Can electronic or smart locks be rekeyed?
Some smart locks include a mechanical key cylinder that may have its own service options, but codes, apps, and electronic credentials are different from a mechanical rekey. Provide the exact model before assuming it can be rekeyed.
