Rekeying changes the inside of a lock so that a new key works and every old key becomes useless. The lock itself stays on the door. For a lot of La Puente homes, that is the most sensible way to regain control after you buy a house, go through a breakup, let a roommate go, or hand over a rental. You do not need to guess who still has a copy of the old key.

La Puente is largely a neighborhood of 1950s and 1960s single-story stucco tract homes, and many still carry original or builder-grade entry locksets and aging deadbolts. Some of those locks are worth rekeying and some are not. We look at the hardware first and tell you honestly which camp yours falls into. A sound deadbolt with a worn cylinder is a great rekey candidate. A deadbolt that sticks, rattles or no longer lines up with the strike plate may be better replaced.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no shop to drive to. We bring the tools and key stock to you, whether that is a house near Hudson, an apartment off Amar Road, or a storefront on Valley Boulevard.

How it works in La Puente

  1. 1

    Call and describe the doors

    Call (323) 997-8867 and tell us how many locks need rekeying, what kind they are (entry knob, deadbolt, garage side door, gate) and why you want the change. If you have an ADU or converted garage, mention it so we can plan for keyed-alike needs.

  2. 2

    We come to you

    We are 24/7 and fully mobile, so we travel to your La Puente address with the tools and parts needed. There is no storefront visit. On arrival we confirm the work with you before we start.

  3. 3

    Inspect each lock

    We check that every lock operates smoothly, the bolt extends fully, and the door and strike line up. Sun-warped doors and settled frames are common in older tract homes, and a misaligned deadbolt can be adjusted or flagged for replacement.

  4. 4

    Rekey the cylinders

    We remove each cylinder, replace the internal pins to match a new key, and reassemble it. Old keys no longer turn the lock. If you want several locks on one key, such as the front door, back door and an ADU, we set them keyed-alike.

  5. 5

    Test and hand over keys

    We test every new key several times on every lock and confirm the old key fails. You get your new keys, and we can cut extras on the spot if you need them for family or tenants.

What affects the price

  • The number of cylinders to rekey. A single front deadbolt is a smaller job than a whole house, a rear door and a garage side door.
  • Whether you want locks keyed-alike so one key works on the main house and an ADU or converted garage, versus each lock on its own key.
  • The condition of the hardware. Worn or sticking locks may need repair or replacement parts in addition to rekeying.
  • The lock brand and type, since some high-security or commercial cylinders take more time and specialized parts.
  • How many new keys you need cut, particularly for a landlord handing keys to several tenants.
  • The time of day and the location of the job, as after-hours calls may be priced differently from daytime appointments.

Why La Puente chooses us

  • Fully mobile service, so the work happens at your door and we are not tied to a storefront counter.
  • Available 24/7, which matters when you discover a missing key late at night or need locks changed right after a move.
  • In business since 1987 under owner and lead tech David Shar, with deep experience in older tract-home hardware.
  • Honest rekey-or-replace advice. If a 1950s deadbolt is too worn to be worth keeping, we say so rather than rekeying it just to make the sale.
  • We handle keyed-alike setups for houses with ADUs and converted garages, a common arrangement in La Puente.
  • We also work on commercial aluminum-storefront cylinders, so one call covers a rental property and a shop.

Lock Rekeying across La Puente

La Puente's housing is mostly modest single-story stucco tract homes from the 1950s and 60s, and rekeying is a regular request across the city, from Hudson and Sunset to the Valinda and Bassett areas next door. In ZIP code 91744 and across 91746 and 91747, we see original entry locksets that have outlasted several owners and many unaccounted-for keys. A rekey is a quick way to start fresh without replacing hardware that still works.

Older homes bring their own quirks. On Valinda-side streets, a sun-warped door can make a deadbolt drag or stick, and rekeying alone will not fix that. We realign the bolt and strike where we can and recommend a fresh lockset when the old one is failing. Landlords with a converted-garage ADU behind the main house often ask us to rekey both doors keyed-alike after a tenant change, so one key covers everything while old tenant keys go dead.

We also work with small businesses along Valley Boulevard and Hacienda Boulevard, where aluminum storefront doors and small strip-mall units have their own cylinder types. Whether you are near La Puente Park, by The Donut Hole, or just off I-10, SR-60 or Amar Road, call (323) 997-8867 and we will come to you.

Lock Rekeying in La Puente — FAQs

What is the difference between rekeying and replacing a lock?
Rekeying changes the internal pins so a new key works and the old keys do not, while the lock stays on the door. Replacing swaps the whole lock. Rekeying suits locks in good shape. Replacement suits worn, damaged or sticking hardware.
Should I rekey after buying a house in La Puente?
Yes, it is a smart first step. You cannot know how many copies of the old keys exist, from previous owners, agents, contractors or neighbors. Call (323) 997-8867 and we can rekey every exterior lock so only your keys work.
Can you rekey the main house and my ADU to the same key?
Yes. We can set locks keyed-alike so one key opens the main house and a converted garage or ADU. If you prefer separate keys for tenants, we can do that instead and keep a master arrangement where appropriate.
My deadbolt sticks on a hot day. Will rekeying fix it?
Not by itself. Sticking is often caused by a warped door or misaligned strike, which is common in older tract homes. We check alignment and adjust it, and if the lock is failing we will suggest replacing it.
Do I need to be home during the rekey?
Someone authorized should be present to let us in and receive the new keys. That is usually the owner, a property manager or a tenant.
Can you rekey commercial doors on Valley Boulevard?
Yes. We work on aluminum-storefront cylinders and other commercial locks. If a storefront deadbolt or pivot has failed, we can advise on a cylinder swap. Call (323) 997-8867 to describe your door.
Are you available at night or on weekends?
Yes. We are available 24/7 and fully mobile, so we can come to your La Puente location at any hour. There is no storefront to visit.
How is the cost of rekeying determined?
Cost depends on how many cylinders, whether they are keyed-alike, the lock type and condition, how many keys you need and when you call. We explain what applies before beginning the work.
