A lock does not last forever. Springs weaken, latches stick, finishes wear through, keys get harder to turn, and a door that has been forced or kicked can leave hardware that no longer does its job. Replacing the lock, rather than patching it, is often the cleanest way to get a door you can trust again.

Crenshaw Lock Company has served Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to visit. We bring the work to your front door, back door, patio door or garage entry, and we replace the hardware right there. Owner and lead technician David Shar built the company on honest, hands-on work.

Lock replacement is different from rekeying. Rekeying changes the inner pins so old keys stop working while the lock stays. Replacement installs a new lock entirely, which makes sense when the hardware is damaged, loose, outdated, mismatched across doors, or simply no longer the level of security you want. We will tell you which one fits your situation.

How our lock replacement service works

  1. 1

    Tell us about the door and the problem

    Call (323) 997-8867 and describe what is happening: a sticking deadbolt, a broken handle, a break-in, a move-in, or a desire to upgrade. We note the door type and what hardware you have now.

  2. 2

    We come to you

    Because we are fully mobile, a technician drives to your home with hardware and tools. We are available around the clock, including nights, weekends and holidays.

  3. 3

    Inspect the existing lock and door

    We check the lock, strike plate, latch alignment and the door itself. If the lock can be repaired or rekeyed more sensibly, we say so before replacing anything.

  4. 4

    Choose the new hardware

    We go over options for knobs, levers, deadbolts and keyed-alike sets, plus finishes and security features, so the new lock fits how you use the door.

  5. 5

    Install and fit

    We remove the old lock, install the new one, and make sure the bolt throws fully into a solid strike plate. Where we can, we adjust the fit so it operates smoothly.

  6. 6

    Test and hand over keys

    We test the lock repeatedly from both sides with the door open and closed, then hand you the keys and show you how everything works.

What affects the price

  • The type of lock: a basic knob, a lever, a single-cylinder deadbolt, or a higher-security or smart-capable model all differ in hardware cost.
  • How many locks are being replaced, and whether you want them keyed alike so one key opens every door.
  • The condition of the door and frame, since a damaged strike plate, loose jamb or misaligned bore may need extra work.
  • Finish and style choices, which vary the hardware cost.
  • The time of day and your location within our service area, since after-hours and longer drives can affect the total.
  • Whether the job is a planned replacement or an urgent one after a break-in or lockout.

Why choose us

  • Fully mobile service: we do the work at your door, so you never carry a lock to a shop or leave your home unsecured.
  • In business since 1987, with owner and lead technician David Shar behind the work.
  • We tell you honestly when a rekey or repair will do instead of a full replacement.
  • Available 24/7 for urgent situations such as a forced door or a lock that has failed.
  • We test every new lock from both sides and walk you through it before we leave.
  • We can match several locks to one key so your household is not carrying a ring of keys.

Lock Replacement — FAQs

What is the difference between lock replacement and rekeying?
Rekeying changes the internal pins so old keys no longer work, while keeping the same lock. Replacement installs entirely new hardware. If your lock is damaged, worn or outdated, replacement is usually better. Call (323) 997-8867 and we will help you decide.
When should I replace a lock instead of repairing it?
Replace it if the lock sticks or jams often, the key is hard to turn, parts are loose or broken, the finish has failed, or the door was forced. A lock that no longer matches your security needs is also a good candidate.
Can you replace locks at night or on weekends?
Yes. We are available 24/7, including nights, weekends and holidays. Call (323) 997-8867 and we will come to your home.
Can all my doors use the same key?
In most cases yes. We can install new locks keyed alike so one key operates your front, back and side doors, depending on the hardware you choose.
Do I need to be home?
Someone should be present, or you must arrange access, so we can verify the work is for your property and test the locks with you before finishing.
Will a new lock fit my existing door?
Most standard residential doors accept common replacement locks. We check the bore holes, latch and strike plate first, and if the door needs adjustment we explain what is required.
What if my door was damaged in a break-in?
We inspect the lock, strike plate and frame. Often we can replace the lock and reinforce or repair the strike area so the door is secure again. Call (323) 997-8867 for prompt help.
Do you have a shop I can visit?
No. We are fully mobile and come to you throughout Greater Los Angeles and parts of Ventura County, so everything is done at your door.
