Rekeying changes the inside of a lock so a different key operates it and every old key becomes useless. The lock itself stays on the door. That makes it one of the most practical security steps after you buy or rent a home, end a roommate arrangement, part ways with a contractor, or lose a set of keys.

You rarely need new locks to get that peace of mind. If your deadbolts and knobs are in good working shape, rekeying gives you new key control without replacing hardware you already like. It also lets us set several locks to one key, so you carry one key instead of a ring of them.

Crenshaw Lock Company has served Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, with no storefront to visit. We bring the tools and key stock to your door, day or night, and we will tell you honestly if a lock is too worn or damaged to rekey well.

How our lock rekeying service works

  1. 1

    Tell us about your locks

    Call (323) 997-8867 and describe the doors involved, the brand of locks if you know it, and why you want them rekeyed. That helps us arrive prepared.

  2. 2

    We come to you

    Our mobile technician travels to your home with pinning kits and key blanks. There is nothing to drop off and no trip to a shop.

  3. 3

    Inspect each lock

    Before taking anything apart we check that each lock operates smoothly and is sound enough to rekey. If one is badly worn or damaged, we explain your options.

  4. 4

    Change the pins and cut new keys

    We remove the cylinder, replace the internal pin configuration, and cut new keys to match. Several locks can be set to the same key if you want.

  5. 5

    Test and hand over

    We reinstall the cylinders, test each lock with the new key, and confirm the old keys no longer turn. You leave with working keys and locks that behave properly.

What affects the price

  • How many locks or cylinders need to be rekeyed
  • Whether you want all locks keyed alike to a single key
  • The brand and type of lock, since some are more involved to rekey than others
  • How many copies of the new keys you need
  • Time of day, since after-hours and emergency visits differ from scheduled daytime work
  • Your location within our service area and travel involved

Why choose us

  • Fully mobile service: we rekey on site at your door, with no storefront or drop-off
  • In business since 1987, with owner David Shar leading the work
  • Honest recommendations: if a lock is worn out, we say so rather than rekeying something that should be replaced
  • Available 24/7 for urgent situations such as a lost key set or a recent break-up or move-out
  • We can set multiple locks to one key so your household carries fewer keys
  • We test every lock before leaving and confirm old keys no longer work

We rekey locks throughout Greater Los Angeles, from the San Fernando Valley and the San Gabriel Valley to the South Bay and Harbor area, the Westside, and the Gateway Cities. We also work across Central and South LA, so whether you are in a house, condo, or apartment, we come to you.

Our service reaches parts of Ventura County as well. Because we are fully mobile, availability depends on where our technician is at the moment, so call (323) 997-8867 and we will talk through your location and timing.

Lock Rekeying — FAQs

What is the difference between rekeying and changing locks?
Rekeying changes the pins inside your existing lock so it works with a new key. Changing locks replaces the hardware entirely. Rekeying is often enough when your locks are in good condition.
Will my old keys still work after rekeying?
No. Once a lock is rekeyed, the old keys no longer turn it. That is the main purpose, especially after a move or lost keys.
Should I rekey after buying or renting a home?
It is a smart step, since you cannot know how many copies of the old keys exist. Call (323) 997-8867 to arrange a visit.
Can you make all my locks use the same key?
Usually yes. We can key several locks alike, such as front and back deadbolts, so one key opens them all.
Can every lock be rekeyed?
Most standard residential locks can. Some are worn, damaged, or low quality and are better replaced. We will inspect and tell you honestly.
Do I need to be home during the rekey?
Someone should be present or arrange access so we can reach each lock and hand you the new keys, and you can test them.
How long does rekeying take?
It depends on the number and type of locks. We can give a general idea when you call (323) 997-8867.
Do you rekey after hours?
Yes, we are available 24/7. Call (323) 997-8867 any time, and note that after-hours visits can affect the cost.
