A dead or missing key fob can stop your day fast. In Westmont, plenty of people park on the street in front of a bungalow or duplex, and many drive daily along Western Avenue, Vermont Avenue, and Imperial Highway. When the fob dies, gets lost, or cracks after one drop too many, you need a replacement that actually starts the car, not just one that looks right.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around mobile service. We are fully mobile, with no storefront to visit and no tow to a shop. We bring the equipment to wherever the vehicle is sitting, and we are available 24 hours a day, every day.

We replace and program standard remote fobs, flip-key remotes, and smart or proximity keys. We can often work even when every existing key is gone, which is called an all-keys-lost situation. Because vehicles differ so much by make, model, and year, we confirm what your car needs when you call, so the visit goes smoothly.

How it works in Westmont

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 and tell us the make, model, and year, plus whether you still have any working key. Those details tell us what type of fob and programming your car uses.

  2. 2

    We come to you

    Because we are fully mobile, we drive to your location, whether that is a driveway near Vermont Knolls, a curb in West Athens, or a parking lot along Imperial Highway.

  3. 3

    Verify ownership

    Before cutting or programming anything, we ask for proof that the vehicle is yours, such as registration and photo ID. This protects you and is a standard practice for responsible locksmiths.

  4. 4

    Cut the key and program the fob

    If your fob includes an emergency or flip key blade, we cut it to match. Then we program the new fob or smart key to the vehicle's immobilizer and remote functions.

  5. 5

    Test everything

    We check that the fob starts the engine and that lock, unlock, trunk, and any panic or remote-start buttons work. For smart keys, we confirm push-button start and proximity entry.

  6. 6

    Cleanup and advice

    If an old lost fob is still registered to the car, we can discuss removing it from the system. We also suggest keeping a spare so you aren't stuck again.

What affects the price

  • Vehicle make, model, and year, since some systems are far more complex to program than others.
  • Type of key: a basic remote, a flip key, or a smart proximity key all involve different hardware.
  • Whether you have a working key to copy or are in an all-keys-lost situation that requires more steps.
  • Whether a physical key blade needs to be cut in addition to programming the electronics.
  • Time of day and location, since we serve customers 24/7 and travel to you.
  • Whether you need one fob or additional spares made in the same visit.

Why Westmont chooses us

  • Fully mobile service: we work at your car, so you do not have to arrange a tow or find a shop.
  • In business since 1987, with owner David Shar leading the work.
  • 24/7 availability, which matters when a fob fails late at night or before an early commute.
  • We handle both traditional remote fobs and smart or proximity keys.
  • We verify ownership before programming, a step we consider part of doing the job right.
  • We tell you what your vehicle needs when you call, so you know the plan before we arrive.

Key Fob Replacement across Westmont

Westmont sits in unincorporated Los Angeles County, and daily life here revolves around Western Avenue, Vermont Avenue, Imperial Highway, Manchester Avenue, and Florence Avenue. Many residents park on the street beside 1920s to 1950s stucco bungalows, duplexes, and small apartment buildings, where there is often no garage and no easy way to get a spare key. We regularly serve drivers in ZIP codes 90047 and 90044, from the Western Avenue corridor to the Vermont Avenue corridor.

If your fob quits while you are running errands along the Imperial Highway commercial strip, near the Vermont and Manchester corridor, or after an event at Jesse Owens Community Regional Park on South Western Avenue, we can meet you there. We also help parents and staff near Washington Preparatory High School who find their fob missing at the end of a long day.

Our neighbors in Vermont Knolls and West Athens call us for the same reasons: a lost fob, a worn-out remote, or a cracked case. Westmont also has many homes and small businesses with older locks, and while this page is about vehicle keys, we can also help with home rekeying or lock replacement during the same visit if you need it.

Key Fob Replacement in Westmont — FAQs

Can you replace a key fob if I lost all my keys?
In many cases, yes. All-keys-lost situations take more steps than copying an existing key, but we can often cut and program a new key on site. Call (323) 997-8867 with your vehicle details and we will tell you what to expect.
Do you come to me in Westmont?
Yes. We are fully mobile and have no storefront. We come to your car in Westmont, including the Western Avenue and Vermont Avenue corridors, and neighboring areas like West Athens and Vermont Knolls.
Are you available at night or on weekends?
Yes, we operate 24/7. If your fob fails late at night or on a holiday, call (323) 997-8867 and we will help.
Can you program smart or push-button start keys?
We replace and program smart and proximity keys as well as standard remotes and flip keys. Compatibility depends on the vehicle, so tell us the make, model, and year when you call.
Why not just go to the dealership?
A dealer may be an option for some vehicles, but it usually means getting your car there. With our mobile service, we come to you, which can be a big help if the car will not start or you cannot drive it.
What do I need to show to get a new fob?
We ask for proof of ownership, typically registration or title and a matching photo ID. We do this to make sure keys only go to the rightful owner.
How is the price determined?
It depends on the vehicle, the key type, whether a blade must be cut, and whether you have an existing key. We do not quote numbers on this page, but you can call (323) 997-8867 to discuss your situation.
Should I make a spare fob?
We recommend it. Having a spare programmed during the same visit is often easier than dealing with another emergency later, and it gives you a backup if the first one is lost or damaged.
