A dead or missing key fob is a bigger problem in Acton than in most places. Parcels here are spread out, the nearest dealership is a long drive down CA-14, and many households rely on their vehicles for everything from hauling feed to commuting toward the Metrolink Acton station. When the fob stops working, towing a car to a dealer is often the slowest and most expensive way to fix it.
Crenshaw Lock Company is fully mobile. We have no storefront, so there is nothing to drive to. We bring the equipment to wherever the vehicle is parked: at your home on acreage in Crown Valley, at a trailhead near Vasquez Rocks, or on the shoulder of a rural road. We have served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar leads the work our crew does.
We replace and program remote key fobs, flip keys, and smart or proximity keys. That includes the situation where you have lost every key and need a new one created from scratch, as well as simply replacing a worn-out fob while you still have a working spare. We will tell you honestly what your vehicle needs before any work begins.
How it works in Acton
- 1
Call and describe the situation
Call (323) 997-8867 any time, day or night. Tell us the make, model, and year, whether you have any working key, and where the vehicle is. In Acton, good directions matter, so mention the cross street, gate code, or landmark that will help us find you along a long access road.
- 2
Confirm the vehicle and key type
Not every fob is the same. Some vehicles use a basic remote with a separate blade, others use a transponder flip key, and newer ones use a push-button smart key. We work out which type your vehicle uses so the right fob is ready.
- 3
Verify ownership
Before we create or program a key, we ask for proof that the vehicle is yours, such as registration and a matching ID. This protects you and is a normal part of responsible locksmith work.
- 4
Cut and program the new fob
If a key blade is needed, we cut it on site. We then program the transponder and remote functions to your vehicle's computer. If you have lost all keys, we generate a new one so the car recognizes it.
- 5
Test every function
We test starting the engine, locking and unlocking, the trunk or hatch, and any panic or remote start buttons. If you have older fobs you no longer have, we can discuss removing them from the vehicle's memory where the system allows.
- 6
Leave you with spares in mind
We suggest having a second working key made while we are already there. A spare costs much less effort now than a lost-all-keys call later, especially on a rural property where help is far away.

24/7 Mobile Locksmith across Greater Los Angeles & Ventura County. We answer 24/7.
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, a transponder flip key, or a proximity smart key all involve different parts and programming.
- Whether you have a working key to copy or all keys are lost, which changes the programming steps required.
- Whether a mechanical key blade must be cut in addition to programming the electronics.
- Distance and location of the parcel, since Acton properties can be far apart and travel time is part of the job.
- Time of day, as after-hours and overnight calls differ from daytime appointments.
Why Acton chooses us
- Fully mobile service, so your car never needs to be towed to a dealership to get a working fob.
- In business since 1987, with owner David Shar personally involved in the work.
- Available 24/7, which matters when you are stranded far from town after a hike or a late shift.
- Honest guidance about whether you need a full replacement, a reprogram, or just a new battery or shell.
- Experience with rural access, including long gravel roads and gated driveways, so we plan for the trip.
- We explain what the job involves before we begin and do not push work you do not need.
Key Fob Replacement across Acton
Acton is a spread-out community, and that shapes how we handle key fob jobs. Whether you live in the Acton townsite, up in Crown Valley, along Aliso Canyon Rd, or out toward Soledad Canyon, we come to your driveway. Many properties here are large-lot horse and ranch parcels with gated entries and long access roads, so a clear address, gate code, and description of the turn-off help us arrive without delay.
Fob trouble does not always happen at home. Hikers and visitors at Vasquez Rocks Natural Area Park, campers at the Acton KOA, and people visiting the Shambala Preserve sometimes find a fob lost on a trail or drained of battery far from services. Commuters parking near the Metrolink Acton station can also be stuck at the end of a long day. If you are anywhere in ZIP code 93510, call (323) 997-8867 and we will come to the vehicle.
We also see cases along CA-14, Sierra Highway, and Soledad Canyon Rd, where a vehicle owner is stranded without a working key and cell coverage can be uneven near Escondido Canyon. Tell us your location as precisely as you can, and we will plan the best route. Because we are mobile only, there is no shop visit; the work happens right where you are.
