A key fob stops working at the worst times: in a Colima Road shopping center lot after dinner, at a trailhead near Schabarum Regional Park, or in your driveway on a weekday morning. Sometimes the fob is simply lost. Sometimes the battery is dead, the case is cracked, or the buttons wear out. Either way, you need a replacement that your car will actually accept, and you probably do not want to arrange a tow just to get one.
Crenshaw Lock Company is fully mobile. We have no storefront for you to visit. Our technician drives to your vehicle anywhere in Hacienda Heights, and we are available around the clock. Owner and lead tech David Shar has run the business since 1987, and that history in Greater Los Angeles and Ventura County means we have seen how fobs behave across a very wide range of makes and model years.
This page explains what replacing a fob involves, what affects the cost, and what to expect if you call us from the Heights, the Skyline hillside tracts, the Stimson-area flats, or anywhere nearby. If you would rather just talk it through, call (323) 997-8867.
How it works in Hacienda Heights
- 1
You call and describe the situation
Tell us the make, model, and year of the vehicle, and whether you have any working keys left. Also tell us where the car is parked. Those details help us understand whether you need a simple remote, a transponder key with remote, or a smart proximity key.
- 2
We come to the car
We are mobile only, so the work happens where the vehicle sits: a driveway in the Stimson-area flats, a hillside street in Skyline, or a lot along Hacienda Blvd. There is nothing to tow and no shop to visit.
- 3
Ownership is verified
Before cutting or programming anything, we ask for proof that the vehicle is yours, typically ID and registration or title. This protects you, because it keeps someone else from getting a key to your car.
- 4
The fob is prepared and programmed
Depending on the vehicle, we cut a blade if one is needed, then program the transponder and remote functions to the car. For smart keys, we pair the new key with the vehicle's system so push-button start and keyless entry work.
- 5
Everything is tested before we leave
We check lock, unlock, trunk, panic, and start functions, and confirm that the car recognizes the key. If you want, we can also test or advise on any spare key so you are not caught out again.

Key Fob Replacement across Hacienda Heights
Hacienda Heights is a spread-out, hilly community, and that shapes how people lose or damage fobs. Residents in the Heights and the Skyline hillside tracts often park on steep streets or in driveways above the road, where a fob dropped on a walk or hike can vanish easily. In the Stimson-area flats, many families share vehicles and keep older cars alongside newer ones, so a single missing fob can affect the whole household. We drive to each of these areas, including addresses in ZIP code 91745.
Daily life here also involves a lot of driving. Commuters use SR-60, and errands run along Colima Rd, Hacienda Blvd, and Azusa Ave. Strip centers on those corridors are common places for a dead fob or lost key to leave someone stranded. Visitors to Hsi Lai Temple, Steinmetz Park, and the trails of the Puente Hills may also find themselves far from home without a working key. We meet you at the car instead of asking you to arrange a tow.
Because many homes here are on hillsides with gated or sloped driveways, we plan for tight access and park carefully when we arrive. If you are locked out of your home as well as your car, we can discuss that when you call (323) 997-8867.
