A lock does not fail all at once. A deadbolt that needs a little lift to throw, a key that sticks and has to be wiggled, a knob that spins loosely in the door: these are the signs that the hardware has had its years. In El Monte, where so much of the housing was built in the 1940s through the 1960s, a lot of front doors are still carrying original-era Kwikset or Schlage knobs and deadbolts that have been turned thousands of times, rekeyed by nobody, and handed down through several tenants or owners.

Lock replacement means removing the old hardware and installing new locks that fit the door properly and are keyed the way you need. Sometimes that is a straight swap of a worn deadbolt. Sometimes it is a full set of entry hardware matched to one key so you are not carrying a ring of them. Sometimes it is a reaction to something specific: a lost set of keys, a break-in attempt that damaged the strike or latch, or a new household moving in and wanting no unknown keys in circulation.

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 and available around the clock. There is no storefront to visit; we bring the tools and hardware options to your door in El Monte and do the work on site.

How it works in El Monte

  1. 1

    Tell us what is going on

    Call (323) 997-8867 and describe the door and the problem: a worn deadbolt, a damaged latch, a lost key, or a tenant turnover. Mention whether it is a house, apartment, mobile-home unit or a business, since each uses different hardware.

  2. 2

    We come to you

    Because we are mobile, the work happens at your property. We look at the door, the existing lock, the bore holes, the strike plate and the frame, because a new lock is only as good as the door it is sitting in.

  3. 3

    Choose the right hardware

    We talk through options that suit your door and how you use it: standard knob and deadbolt sets, keyed-alike sets, higher-security deadbolts, or specialty hardware for narrow-stile and park-model doors. We explain the tradeoffs plainly and you decide.

  4. 4

    Remove the old lock and install the new

    We take out the worn hardware, check that the door prep is clean, and fit the new lock so the bolt throws smoothly into a properly seated strike. Where a strike plate or latch is loose from age or forced entry, we address that too.

  5. 5

    Test and hand over keys

    We operate every lock repeatedly with the door open and closed, confirm the keys work cleanly, and make sure the door latches without force. You leave with working keys and a door that locks the way it should.

What affects the price

  • The number of locks being replaced, from a single deadbolt to every exterior door on a house or a full apartment building.
  • The type and grade of hardware you choose, since basic residential sets and higher-security deadbolts differ in construction and cost.
  • Whether the doors are standard or specialty, such as mobile-home doors with narrow stiles and park-model latch systems, or aluminum storefront doors and roll-up gate locks.
  • The condition of the door and frame, including any damaged bore holes, strike plates or latches that need repair for the new lock to work properly.
  • Whether you want locks keyed alike, or a master-key arrangement for a multi-unit property.
  • Timing and location, including after-hours or urgent calls, which we will explain when you phone.

Why El Monte chooses us

  • Fully mobile service: we work at your door, so there is nothing to drop off and no store to visit.
  • In business since 1987, with long familiarity with the Kwikset and Schlage hardware common in postwar tract homes like those around El Monte.
  • Available 24/7, including nights and weekends, when a break-in or lost key cannot wait.
  • Experience with the less common doors in town: courtyard apartment units, mobile-home park doors and aluminum storefronts with security gates.
  • We check the door and frame, not just the lock, so the new hardware actually performs.
  • Straight explanations of your options, without pressure to buy more than the door needs.

Lock Replacement across El Monte

El Monte is a city of mostly single-story stucco homes laid out in postwar tracts, and many of those front doors still hold their original-era knob-and-deadbolt hardware. In Norwood and around the older downtown core near Valley Mall, you will also find 1920s and 1930s bungalows where doors have been refitted over the decades and the bore holes and strikes may no longer line up cleanly. Replacing a lock there often means paying attention to the door itself, not just swapping a cylinder. In Mountain View, we see the same mix of aging tract hardware and households wanting fresh keys after a move.

The city also has a large base of courtyard and garden apartments, including buildings off Garvey Ave where a tenant move-out is a common reason to replace or rekey locks so old keys stop working. Several mobile-home parks in the area use narrow-stile doors and park-model latch systems that standard hardware does not always fit, so we match the replacement to the door. Along Valley Blvd and Garvey Ave, aluminum-storefront shops with roll-up gates sometimes need a seized or jammed cylinder replaced.

We serve all El Monte ZIP codes, including 91731, 91732, 91733, 91734 and 91735, from the area around the El Monte Bus Station and Metrolink station to homes near Gibson Mariposa Park and the Rio Hondo and San Gabriel River corridor. With the I-10, I-605, Peck Rd and Santa Anita Ave all close by, call (323) 997-8867 any hour and we will work out how to get to you.

Lock Replacement in El Monte — FAQs

When should I replace a lock instead of rekeying it?
Rekeying changes the internal pins so old keys stop working, and it is a good fit when the hardware is still in good shape. Replacement makes sense when the lock is worn, damaged, loose in the door, outdated, or when you want better security. Call (323) 997-8867 and we can help you decide.
Can you replace locks at night or on weekends in El Monte?
Yes. We are a 24/7 mobile locksmith, so you can call (323) 997-8867 at any hour about a damaged lock, a lost key, or a door that will not secure.
My house is an older El Monte tract home. Will new locks fit?
Usually yes. Many postwar homes use standard-bore doors that accept common deadbolts and knob sets. If the door has been drilled badly or the frame is worn, we adjust or repair so the new lock sits correctly.
Do you handle mobile-home park doors?
Yes. Mobile-home and park-model doors often have narrow stiles and different latch systems, so we match hardware to the door rather than forcing a standard set.
I manage an apartment building off Garvey Ave. Can you replace locks after a tenant moves out?
We can replace or rekey locks between tenants, and set up units keyed alike or on a master arrangement where appropriate. Call (323) 997-8867 to describe the building.
My storefront gate lock on Valley Blvd is jammed. Can that be replaced?
Yes. Seized or jammed cylinders on roll-up security gates and aluminum storefront doors are something we replace on site.
Do I need to be home during the replacement?
Someone authorized should be present, or we should confirm access arrangements in advance, so we can test the locks and hand over keys.
How do you set the price for a lock replacement?
It depends on the number of locks, hardware grade, door type, and the condition of the door and frame. We do not quote figures on this page, but we will explain what affects the cost when you call.
