Automotive Locksmith across greater Los Angeles, Ventura County & the Bay Area.

Here is how One & Only Locksmith handles automotive locksmith work.

Automotive Locksmith work covers car lockouts, keys cut and programmed at the vehicle (transponder, remote and proximity keys), ignition repair and broken key extraction, for most makes and model years.

We dispatch across greater Los Angeles, Ventura County, Silicon Valley and the Bay Area; see the city pages for local detail. The dispatch line at (888) 492-0666 is answered around the clock.

• Lockouts: Car Lockout and Trunk Lockout. Doors and trunks opened at the vehicle without damaging the weatherstrip, paint or electronics.
• Keys cut and programmed: Car Key Replacement, Lost Car Key Replacement and Spare Car Key & Key Duplication. All-keys-lost and spare keys, cut by code and programmed to the immobilizer on site.
• Chip, remote and proximity keys: Transponder Key Programming, Key Fob Programming and Smart / Proximity Key Programming. Transponder chips, remote-head keys, flip keys and push-to-start fobs.
• Ignitions and broken keys: Ignition Repair / Replacement and Broken Key Extraction. Worn or seized cylinders and key fragments removed from doors and ignitions.
• Other vehicles: Motorcycle Key Replacement, RV, Boat & Trailer Key Replacement and Semi-Truck & Fleet Locksmith. Motorcycles, RVs, boats, trailers and commercial fleets.

Each of these has its own page with what is included, what to have ready and the questions people ask about that job.

1. Call (888) 492-0666 with the year, make, model and key type. Plain blade, chip key, remote-head or push-to-start fob, and how many working keys you have, if any.
2. The dispatcher confirms whether it can be done at the vehicle. Most makes and model years can; some late-model vehicles require dealer authorization or a minimum number of existing keys, and you hear that before anyone is sent.
3. The technician verifies ownership at the vehicle. Registration, title or insurance card plus matching photo ID; for company vehicles, authorization from the company.
4. The key is cut and programmed, or the lock is opened. Keys are cut by code or to the original, then paired to the immobilizer or proximity system.
5. Everything is tested. Ignition or push-button start, every door, the trunk or hatch and the remote functions.
6. A spare can be cut at the same visit, and you receive a receipt. Adding a second key while the programmer is connected is simpler than a return trip.

We cover most makes and model years; we confirm your year, make and model on the phone. The key type determines what has to happen at the vehicle.

• Plain cut keys: mostly older vehicles with no chip; cut to code or to the original.
• Transponder (chip) keys: the chip must be programmed to the immobilizer. A cut blade alone will open the door but will not start the car.
• Remote-head and flip keys: blade, chip and remote in one unit; both the chip and the remote are paired.
• Smart and proximity fobs: push-to-start vehicles; paired to the vehicle's keyless system.
• High-security (laser-cut or sidewinder) blades: cut on a dedicated machine rather than a standard duplicator.
• Motorcycle, RV, trailer and fleet keys: many are plain or coded cuts; some late-model motorcycles use chips too.
• Limits: some late-model makes require dealer authorization or a security gateway login, and some need a minimum number of existing keys to add one. The dispatcher confirms this by year, make and model before sending anyone.

The price follows from a few things you can tell the dispatcher on the phone.

• Year, make and model: the key blank, chip type and programming method all follow from the vehicle.
• Key type: a plain cut blade, a transponder key, a remote-head key or a push-to-start proximity fob are different parts with different programming.
• All keys lost versus adding a spare: with no working key, the lock or immobilizer has to be read or decoded first.
• Dealer-only steps: some late-model makes require dealer authorization or a security gateway login, which changes what can be done at the roadside.
• Time of day and distance: ask the dispatcher whether an after-hours charge applies to your location.

Once the dispatcher knows the lock, door or vehicle, they can give you a range on the phone. The technician confirms a written quote before any work starts, and if you decide not to proceed at that point, you say so then.

Payment is by Cash, Credit Card, Debit Card, Apple Pay and Google Pay, and you receive an itemized receipt listing what was done.
