Losing a key fob, or watching one die in the middle of a day, is a particular kind of frustration. Modern fobs do more than unlock doors. Many carry a transponder chip the engine immobilizer must recognize, and smart or proximity keys talk to the car wirelessly. Replacing one is not the same as cutting a metal key, and that is why a dealer trip, often with a tow, is what many drivers assume they are stuck with.

Crenshaw Lock Company is fully mobile, so there is no shop to drive to. In West Covina that matters, because the city is spread out along Interstate 10 and SR-60, and most people park at a tract home, an apartment complex, a mall lot, or a hospital garage. We bring the equipment to wherever the vehicle sits and handle the replacement and programming there. David Shar has run the business since 1987, and the work of matching a new fob to a car is something we have done in every kind of setting.

This page explains how fob replacement works, what changes the cost, and what to have ready when you call. We do not quote prices without knowing your vehicle, because the make, model, year, and key type decide almost everything. Call (323) 997-8867 any hour and we will talk through your situation honestly.

How it works in West Covina

  1. 1

    Tell us about the vehicle

    When you call, we ask for the make, model, and year, and what kind of key you have or had: a flip key, a standard remote head key, or a push-button-start smart key. We also ask whether you still have any working key. That determines the approach.

  2. 2

    We come to your location

    We are 24/7 and fully mobile, so we meet you where the car is, whether that is a driveway in the South Hills, an apartment carport off Azusa Ave, or a lot near Plaza West Covina. Nothing needs to be towed.

  3. 3

    Confirm ownership

    Before we create a key for any vehicle, we ask for proof that it is yours, typically a photo ID along with registration or title. This protects you and every other driver on the road.

  4. 4

    Cut and prepare the fob

    If your car uses a physical blade, we cut it to match the vehicle. We then select a fob compatible with your car's frequency and chip type so that it can be programmed properly.

  5. 5

    Program to the vehicle

    We pair the new fob with the car's immobilizer and remote system using professional programming equipment. Depending on the vehicle, we may also add a spare or remove a lost key from the system.

  6. 6

    Test everything

    Before we finish, we test lock and unlock, trunk or hatch, panic, and remote functions, and confirm the car starts and runs with the new key. You leave knowing it all 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, and a push-button smart key differ in hardware and programming effort.
  • Whether you have a working key to copy from or all keys are lost, which can require more extensive programming.
  • How many fobs you want made, since adding a spare during the same visit is often more practical than a second call later.
  • Time of day and location, because after-hours and late-night service is part of how a 24/7 mobile service operates.
  • Whether the old fob has a damaged blade, worn buttons, or a failed battery, which sometimes means a simple repair instead of a full replacement.

Why West Covina chooses us

  • Fully mobile: we work at your vehicle, with no storefront and no need to tow the car to a dealership.
  • In business since 1987, with David Shar as owner and lead technician.
  • Available 24/7, which matters when a fob fails at night, in a hospital garage, or after a late shift.
  • We explain options plainly, including when a battery swap or a repair will solve the problem so you do not pay for a replacement you do not need.
  • Ownership verification on every vehicle, so keys are only made for the rightful owner.
  • Spare fob and lost-key cleanup can be handled in the same visit.

Key Fob Replacement across West Covina

West Covina is a large suburban city, and its parking situations vary widely. In South Hills, many residents park in garages or on steep hillside driveways, and a failed smart key can leave you unable to start a car at home. In Woodside Village and the 1950s and 60s tract neighborhoods, cars often sit in driveways or on the street, and a lost fob usually means a call from the front yard. We handle these at your address, in ZIP codes including 91791 and 91790.

Commercial areas bring a different kind of call. Shoppers and employees at Plaza West Covina and the Eastland Center sometimes find a fob dead or missing after a long shift, and the Eastland / Plaza commercial district has large lots where a mobile technician can work easily. The same goes for staff and visitors near Emanate Health Queen of the Valley Hospital, where people may be parked for many hours and need help at odd times.

With Interstate 10, SR-60, Azusa Ave, Vincent Ave, Glendora Ave, and Sunset Ave running through the city, we serve drivers across ZIP codes 91792 and 91793 as well. Apartment residents near Amar Rd who lose a fob can have a replacement programmed right in the complex parking area. Call (323) 997-8867 and tell us where you are parked.

Key Fob Replacement in West Covina — FAQs

Can you replace a key fob if I lost all my keys?
In many cases, yes. An all-keys-lost situation usually needs more programming than copying from a working key, but we can often do it at your vehicle in West Covina. Call (323) 997-8867 with the make, model, and year.
Do I need to tow my car to a dealer?
Often not. Because we are fully mobile, we bring the cutting and programming equipment to your car, whether it is at home in South Hills or in a lot near Plaza West Covina.
What proof of ownership will you need?
We typically ask for a photo ID and vehicle registration or title that matches the car. We do this for every vehicle to ensure keys go only to the rightful owner.
Is it cheaper to just replace the battery?
Sometimes a dead battery is the whole problem. If a fresh battery or a small repair fixes your fob, we will tell you honestly rather than sell you a replacement. Call (323) 997-8867 and describe the symptoms.
Can you program a fob I bought online?
Sometimes, depending on the vehicle and whether the fob is compatible and unused. Many online fobs are the wrong frequency or are locked to another car, so it is worth calling before you buy.
Do you work at night or on weekends in West Covina?
Yes. We are available 24/7 and mobile, so late-night calls from a mall lot, hospital garage, or your driveway are part of what we do.
Can you make a spare fob while you are there?
Yes, in most cases. Adding a spare during the same visit is often easier and more practical than waiting until the next fob is lost.
Do you handle push-button smart keys as well as basic remotes?
Yes. We work on remote head keys, flip keys, and proximity or smart keys. Coverage depends on the vehicle, so give us the details when you call.
