Most vehicles built since the late 1990s will not start with a plain metal key. Inside the plastic head of the key is a small transponder chip, and the car's immobilizer checks that chip before it lets the engine run. If you have lost your only key, snapped one off, or want a spare before that happens, the new key has to be cut and then programmed to your specific vehicle. That is the work we do.
In Acton this matters more than it might in a dense city. Parcels are spread far apart, many households rely on a truck or SUV to haul feed, trailers and tools, and the nearest dealership is a long drive down CA-14. Being stranded without a working key on a ranch property off Soledad Canyon Rd or Crown Valley Rd is a real inconvenience. Because Crenshaw Lock Company is fully mobile, we bring the equipment to you instead of asking you to get a car you cannot start to a shop.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward, honest automotive and residential work. We have no storefront to visit. Everything happens at your vehicle, and we are available around the clock, including nights, weekends and holidays.
How it works in Acton
- 1
Call and describe the situation
Phone (323) 997-8867 and tell us the make, model and year of the vehicle, and whether you have any working key or none at all. Because Acton properties can be tricky to find, we also ask for clear directions, gate codes if there are any, and a nearby landmark or cross road.
- 2
Confirm the vehicle and key type
Different vehicles use different chip types, blade profiles and programming procedures. We confirm what your vehicle needs before we start, including whether it uses a traditional chip key, a flip key or a push-button start fob, so the right key blank is on hand.
- 3
Verify ownership
Before creating a key for any vehicle, we ask for reasonable proof that it is yours, such as an ID and registration or title. This protects you and every other vehicle owner.
- 4
Cut the key if needed
If you need a new physical key, we cut it on site to match your vehicle's lock. If you already have a blade that turns the ignition, we can move straight to programming.
- 5
Program the transponder to the immobilizer
We connect our programming equipment to the vehicle and register the new chip so the immobilizer recognizes it. Depending on the vehicle, this can also include removing a lost key from the system so it no longer starts the car.
- 6
Test everything before we leave
We test the key in the door, ignition and any remote functions, and start the engine more than once. You should drive away with a key that works, not one that nearly works.

What affects the price
- The make, model and year of the vehicle, since some manufacturers require more involved programming procedures than others.
- Whether you have a working key already or have lost every key, which changes how much work is involved in getting the immobilizer to accept a new one.
- The type of key: a basic chip key, a flip key, a proximity fob or a push-button start key all differ in cost and complexity.
- How many keys you want programmed in one visit, since adding a spare while we are already there is usually more practical than a second trip.
- Your location and access, because Acton parcels can be far apart, and a long drive on a rural access road affects the visit.
- The time of day or night you need service, as true after-hours work is different from a scheduled daytime appointment.
Why Acton chooses us
- Fully mobile service: we come to your driveway, barn lot, trailhead or roadside rather than asking you to tow a vehicle somewhere.
- Available 24/7, which matters when a key goes missing late at night at a rural property with no other option nearby.
- In business since 1987, with David Shar leading the work, so you are dealing with an established local locksmith rather than a call center.
- We explain what your vehicle needs before work starts, including whether an extra spare makes sense, so there are no surprises.
- We handle both the physical key cutting and the electronic programming in one visit for most vehicles.
- We also understand rural property needs, from gated driveways to barn padlocks, so we can help with more than just the car if you need it.
Transponder Key Programming across Acton
Acton covers a lot of ground, from the Acton townsite near Sierra Highway and the Metrolink Acton station to the quieter parcels of Crown Valley, Aliso Canyon and Soledad Canyon. In ZIP code 93510, homes are often custom houses or older ranch homes on acreage, and driveways can be long and gated. When you call (323) 997-8867, a good set of directions, a gate code and a description of where the vehicle sits on the property help us find you without wasted time.
People here depend on their vehicles. A truck that pulls a horse trailer, a work van, or an SUV used for the daily commute down CA-14 cannot sit idle for long. If a key has gone missing on a trail ride near Escondido Canyon or after a weekend at Vasquez Rocks Natural Area Park, we can program a replacement at your location. Visitors staying at the Acton KOA who have lost a key can call us too.
We also know that locks around Acton are not limited to cars. Barn and tack room padlocks seize up, rusted hasps need replacing, and gated driveway keypads need service. If you have a key problem and a property lock problem at the same time, tell us on the phone, and we can plan the visit around both. We are mobile only, with no shop to visit, so every job happens where you are.
