A key fob that stops working rarely does it at a convenient moment. In Alhambra it might happen in a Main Street parking structure after dinner, in a lot off Atlantic Blvd after a shift, or in the driveway of a Craftsman bungalow in the Bean Tract with a car you can't unlock or start. Fobs get lost, cracked, soaked, or simply wear out, and a dead battery is sometimes mistaken for a dead fob.

Crenshaw Lock Company is fully mobile. There is no shop to tow your car to and no storefront to visit; the locksmith drives to you with cutting and programming equipment and works where the vehicle sits. We have served Greater Los Angeles and Ventura County since 1987, under owner and lead technician David Shar, and automotive remotes are a regular part of that work.

This page explains how replacement works, what changes the cost, and what Alhambra drivers should know, from commuters on the I-10 to apartment residents who share a single fob among several people. We cover remote-head keys, flip keys, and smart or proximity keys, and we're available around the clock at (323) 997-8867.

How it works in Alhambra

  1. 1

    Call and describe the situation

    Tell us the make, model, and year, and whether you have any working key left. Say whether the car is locked, whether it starts, and where it's parked. This lets us bring the right fob and programming equipment for your vehicle.

  2. 2

    We drive to your location

    Because we're mobile and available 24/7, we come to you in Alhambra: a curb in Downtown Alhambra, a driveway in Midwick Tract, an apartment carport, or an office lot. We never ask you to tow the car anywhere.

  3. 3

    Verify ownership

    Before cutting or programming anything, we ask for proof that the vehicle is yours, typically a registration or title along with matching photo ID. This protects you and is standard responsible practice.

  4. 4

    Identify and prepare the fob

    We confirm the correct fob type and frequency for your vehicle, and cut an emergency or mechanical key blade if your system uses one. Some vehicles need a transponder chip matched to the car.

  5. 5

    Program and pair with the vehicle

    We pair the new fob to your car's computer so it starts the engine and, where equipped, locks, unlocks, opens the trunk, or triggers a power door. Depending on the vehicle, older fobs may be removed from memory so a lost one can't be used.

  6. 6

    Test everything before we leave

    We test each button, the ignition or push-start function, and the emergency blade, then show you how to use any spare. You leave knowing the new fob works.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others
  • Type of key: a basic remote-head key, a flip key, or a smart proximity key with push-button start
  • Whether you have any working key or this is an all-keys-lost situation that requires creating a key from scratch
  • Whether the fob can be programmed on site or the vehicle needs unusual procedures
  • Number of fobs you need, since adding a spare during the same visit is often more efficient than a second call
  • Time of day and exact location, as after-hours and urgent calls take different scheduling than a planned appointment

Why Alhambra chooses us

  • Fully mobile service: we bring the programming equipment to your car instead of requiring a tow or a trip to a shop.
  • Open 24/7, so a dead fob at midnight near Valley Blvd gets the same attention as a weekday call.
  • In business since 1987 and led by owner David Shar, with decades of hands-on experience across vehicle brands.
  • Ownership verification on every job, which keeps your car safe and keeps us honest.
  • Plain explanations of what is wrong and what your options are, including when a battery swap or fob shell repair is all you need.
  • We also handle home, apartment, and storefront locks, so one call can cover a vehicle and a property issue.

Key Fob Replacement across Alhambra

Alhambra is a city of commuters and homeowners, and fob problems show up in every part of it. In Downtown Alhambra, visitors to the Main Street dining and entertainment corridor and the Garfield Theatre area often park and walk, which is when a lost or cracked fob becomes obvious at the end of the night. Employees at the Alhambra office and retail campus can run into the same problem in a work lot at the end of a shift.

Residential drivers are just as common. Many homes in the Bean Tract, Midwick Tract, and Emery Park are older bungalows with narrow driveways and street parking, so a car may be the only thing locked up when a fob is missing. In Airport Tract and the mid-century apartment buildings across the city, shared cars and a handful of fobs between several family members make duplicates and spares especially useful. We regularly work in 91801 and 91803.

If you drive in from the I-10, along Fremont Ave or Atlantic Blvd, or around the SR-710 gap and Almansor Park, a broken fob can strand you wherever you stop. Call (323) 997-8867 and we'll come to the car, wherever in Alhambra it is.

Key Fob Replacement in Alhambra — FAQs

Can you replace a key fob in Alhambra if I've lost every key?
Yes. An all-keys-lost situation is more involved, but a mobile locksmith can usually create a new key and program it on site. Call (323) 997-8867 with your vehicle details and we'll explain what's needed.
Do I need to tow my car to you?
No. We're fully mobile and there's no storefront to visit. We come to your car in Alhambra, whether it's at home, at work, or on the street.
Is it cheaper than going to the dealer?
We can't promise a comparison for every vehicle, but mobile service removes towing and waiting, and costs depend on your car, key type, and situation. Call (323) 997-8867 to discuss your specific vehicle.
What proof of ownership will you ask for?
Usually the vehicle registration or title plus a matching photo ID. We ask this on every job to protect owners from theft.
Will my old fob still work after you program a new one?
On many vehicles, we can erase lost fobs from the car's memory so they no longer operate it. Whether this is possible depends on the make and model, so ask when you call.
Could my fob just need a new battery?
Often, yes. Weak range, intermittent unlocking, or a dashboard key warning can mean a low battery. If that's the issue, we'll tell you rather than sell you a new fob.
Can you make a spare fob while you're here?
Yes, and it's usually smart to do it during the same visit. Having a spare is useful if several people share one vehicle in an Alhambra household.
Are you available at night and on weekends?
Yes, we're open 24/7. Call (323) 997-8867 any time and we'll arrange to come to your location.
