Rekeying locks in Koreatown
Rekeying changes the inside of the lock so every old key stops working — usually the cheapest way to take back control of who can get in.
What rekeying actually does
A pin-tumbler lock opens when the key lifts a set of small pins to exactly the right heights. Rekeying swaps those pins for a new set, so the lock now needs a new key and none of the old ones work. The lock itself, the handle and the door stay as they are.
When it makes sense
- You've just moved in and don't know how many copies of the old key exist.
- A roommate, partner or employee has moved on.
- You've lost a key and the lock itself is fine.
- You'd like one key for several doors — possible when the locks share a brand and keyway.
If the lock is damaged, worn out, or you want better security, replacing it is the better job — see lock replacement & installation.
Renting? Check this first
Most leases in Los Angeles say you need your landlord's permission before changing or rekeying a lock, and many landlords need a copy of the new key. In older Koreatown buildings with a building master key, rekeying your unit without the building can lock the manager out in an emergency. A quick message to your manager first avoids an awkward conversation later.
How the price works
Rekeying is usually priced per lock plus the visit. Your technician counts the locks, checks they can be rekeyed (some low-cost and some electronic locks can't), and confirms the total before starting. Naklin's service fee is part of that total. More on pricing →

Questions people ask
What's the difference between rekeying and replacing a lock?
Rekeying keeps your lock and changes the pins inside so old keys stop working. Replacing swaps the whole lock — better if it's damaged or worn, or you want a stronger lock.
Can all my locks use one key?
Often, if they're the same brand and take the same type of key. Your technician confirms what's possible — and the price — before starting.
Do I need my landlord's permission to rekey?
If you rent, usually yes: most leases require it, and the building may need a copy of the new key. Check your lease or ask your manager first.
