Losing a key fob is rarely convenient, and in Covina it tends to happen at the worst moments: after a show at the Covina Center for the Performing Arts, in a parking space near Heritage Plaza, or in a driveway in Charter Oak when you realize the only fob is gone. A modern fob is more than a button remote. Many contain a transponder chip, and smart keys talk to the car wirelessly, so a replacement has to be cut where needed and then programmed to your specific vehicle.

Crenshaw Lock Company is fully mobile. We have no storefront for you to drive to, which matters most when you have no working key. Our technician comes to your vehicle, whether it is in a garage, an apartment lot, a street space downtown on Citrus Ave, or a parking lot off Azusa Ave. We have served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business around showing up and doing the work properly.

What we do depends on your situation. Some people have lost every key. Others have one working fob and want a spare before it is too late. Some have a fob with a cracked case, a worn-out button, or a dead battery that did not fix the problem. We handle replacement and programming for remote fobs, flip keys, and smart or proximity keys, and we will tell you plainly what your vehicle requires before any work begins.

How it works in Covina

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 any hour. Tell us the make, model, and year, whether you have any working key, and where the car is in Covina. These details tell us what type of fob and programming the vehicle needs.

  2. 2

    We travel to your location

    Because we are mobile, we meet you at your car, at home, at work, or in a lot near the Metrolink station. There is nothing to tow or drop off in most cases.

  3. 3

    Verify ownership

    Before making or programming a key, we ask for proof that you own the vehicle, such as registration and matching photo ID. This protects you and is standard practice for any responsible locksmith.

  4. 4

    Cut the key and prepare the fob

    If your fob includes a physical key blade, it is cut to match the vehicle. We then check the fob hardware so it is compatible with your car's system.

  5. 5

    Program to the vehicle

    We pair the new fob or smart key with the car so the remote functions, and the immobilizer recognizes the key to start the engine. Where applicable, we can also add a spare or remove a lost fob from the car's memory.

  6. 6

    Test everything before we leave

    We test locking, unlocking, trunk or hatch release, and starting the engine, so you know every function works before we finish.

What affects the price

  • Vehicle make, model, and year, since some brands use more complex security systems than others.
  • Type of key: a basic remote fob, a flip key, or a smart proximity key all involve different hardware and programming.
  • Whether you have a working key already. Cloning or adding a key is often simpler than creating one when all keys are lost.
  • Whether a physical key blade must be cut or a key must be originated from the vehicle's information.
  • Time of day, since we operate 24/7 and late-night or holiday calls can affect the quote.
  • Number of fobs needed, such as adding a spare along with the replacement.

Why Covina chooses us

  • Fully mobile service. We come to your vehicle anywhere in Covina rather than asking you to find a way to a shop.
  • In business since 1987, with owner David Shar leading the work.
  • Available 24/7, so a lost fob at night or on a weekend does not have to wait.
  • Clear explanation upfront of what your vehicle needs, with no vague promises about outcomes.
  • Ownership verification on every job, which protects you from key theft and fraud.
  • Spare and backup options offered at the same visit, so one lost fob does not become a repeat emergency.

Key Fob Replacement across Covina

Covina is an established San Gabriel Valley city, and its car habits reflect that. Residents commute along Interstate 10, the San Bernardino Freeway, and use Azusa Ave, Grand Ave, Badillo St, San Bernardino Rd, and Arrow Hwy for daily errands. Cars sit in Metrolink commuter parking, in apartment lots, and on residential streets, and a lost or failed fob can leave a vehicle stranded in any of them. In ZIP code 91723 near the downtown core, we regularly work around Citrus Ave and the blocks surrounding Heritage Plaza.

Downtown Covina has a walkable historic feel, with 1920s and 30s commercial buildings and Craftsman and Spanish bungalows nearby. Visitors to the Covina Center for the Performing Arts often park on surrounding streets, and a fob lost during an evening out is a call we understand well. We can meet you downtown and program a replacement on the spot.

Further out, Charter Oak (91724) and Covina Hills to the south have ranch-style homes and larger lots, where cars often sit in driveways and garages. ZIP code 91722 is also part of our Covina coverage. If you are in any of these areas and need a key fob replaced, call (323) 997-8867 and we will come to you.

Key Fob Replacement in Covina — FAQs

Can you replace a key fob if I have lost all my keys?
In many cases yes. Replacing when every key is lost takes more steps than copying an existing one, and requirements vary by vehicle. Call (323) 997-8867 with your make, model, and year and we will tell you what is possible.
Do you come to me in Covina?
Yes. We are fully mobile and work at your vehicle, whether at home in Charter Oak, in a lot near downtown, or by the Metrolink station. We do not operate a storefront.
Is key fob replacement available at night?
Yes. We operate 24/7, including nights, weekends, and holidays. Call (323) 997-8867 any time to reach us.
Do I need to prove I own the car?
Yes. We ask for registration or title and matching photo ID before making or programming a key. It is a security safeguard for you.
What is the difference between a remote fob and a smart key?
A remote fob has buttons for locking and unlocking and usually works alongside a key blade or ignition. A smart or proximity key lets you unlock and start the car without taking it out of your pocket. Each needs its own programming.
Will a new fob work if my old one is just dead?
Sometimes a battery swap solves it, and we can check that. If the fob is damaged or the chip has failed, a replacement and programming is the next step.
Can you program a spare fob while you are here?
Usually yes. Adding a spare during the same visit is often simpler than waiting until all keys are lost. Ask when you call.
How is the price determined?
It depends on the vehicle, key type, whether you have a working key, and the time of the call. We explain the factors and give you a clear quote after we know your vehicle. Call (323) 997-8867 to get started.
