Home locksmith services we offer

House and apartment lockouts

Non-destructive entry wherever the lock allows, then a quick check that the door latches properly again.

Rekeying

New pin combination in your existing locks so old keys stop working. Several doors can be set to one key.

Deadbolt installation

Single or double cylinder deadbolts fitted to the door, with a strike plate secured into the frame.

Lock repair

Sticking cylinders, loose handles and latches that will not catch, repaired or replaced.

Mailbox locks

Replacement mailbox locks and keys for houses and apartment mail panels.

Key cutting and copies

Spare keys cut from your original, plus broken key extraction from jammed locks.

Rekey or replace? How we help you decide

If your locks work smoothly and you only need to cut off old keys, after a move, a lost key or a roommate moving out, rekeying is usually the lower-cost choice. We change the pins inside the cylinder and hand you new keys.

Replacement is the better route when a lock is worn, rusted, forced or simply too basic for the door it guards. We can fit higher-security cylinders, sturdier deadbolts or keypad and smart locks, and we explain the difference in price and protection before you choose.

Common home lock problems we fix

  • Key turns but the door will not open
  • Key snapped inside the cylinder
  • Deadbolt hard to throw or retract
  • Lock damaged after an attempted break-in
  • Keys lost or stolen
  • Sliding door or gate lock not catching
  • Smart lock with a dead battery or fault
  • Need one key for every door

Locks and brands we work with

We service residential hardware from common makers including Schlage, Kwikset, Yale, Baldwin and Mul-T-Lock, along with many builder-grade locks found in Los Angeles apartments. If you are unsure what you have, a photo of the lock face helps us quote.

What to expect when you call

  1. Describe the job

    Tell us the address, the door and what is happening. A photo of the lock helps.

  2. Get a quote

    We give you a price before anyone is dispatched, and confirm when a technician is free.

  3. Work on site

    The technician checks ID for lockouts, explains the plan and completes the work from the van.

  4. Test and pay

    Every lock and key is tested with you before we leave. We accept major credit cards.

Frequently asked questions

Do you need proof that I live there?

For lockouts we ask for ID that matches the address, or other reasonable proof such as a lease or mail, once the door is open. It protects you as much as us.

Can you make all my doors use one key?

Usually, yes, if the locks share a compatible keyway. We can rekey them to a single key or suggest matching replacements.

Do you work with landlords and property managers?

Yes. We rekey between tenants, change apartment locks and fit mailbox locks. See our apartment lock change guide.
