Transponder Key Programming — No Dealership Required

Your car has a secret handshake — and your transponder key is the only one that knows the code. Every vehicle manufactured since the mid-1990s uses a microchip embedded in the key head to communicate with the car's immobilizer system. When you insert the key and turn the ignition, the ECU broadcasts a radio frequency signal. The chip responds with a unique encrypted code. Only a verified match allows the engine to start. This anti-theft system is highly effective — and highly inconvenient when you lose your only key.

A standard key copy from a hardware store won't work. The blade might be cut correctly, but without the chip programmed to your specific vehicle, the car simply won't start. Transponder keys must be cut AND programmed by a locksmith with OBD-II diagnostic equipment capable of writing directly to your vehicle's onboard computer.

That's exactly what Cabrera's Key Fob does — at your location, same day, without the dealership markup. The typical dealer cost for a transponder key is $150–$400 for common models, and can exceed $500 for European vehicles. We program transponder keys for Toyota, Honda, Ford, Chevrolet, GMC, Nissan, Hyundai, Kia, Subaru, Mazda, Dodge, Jeep, BMW, Mercedes-Benz, Volkswagen, Chrysler, and virtually every major brand sold in the US market. Call (408) 794-8016 for a free, no-obligation quote.

We support transponder key programming for an extensive range of vehicles including Toyota, Lexus, Honda, Acura, Ford, Lincoln, Mercury, Chevrolet, GMC, Cadillac, Buick, Pontiac, Dodge, Chrysler, Jeep, Ram, Nissan, Infiniti, Hyundai, Kia, BMW, Mini, Mercedes-Benz, Volkswagen, Audi, Subaru, Mazda, Mitsubishi, and many more. Whether your vehicle uses a basic glass chip key, a carbon transponder key, a rolling code chip key, or a high-security transponder key, we have the tools and expertise to cut and program it correctly.

Choosing Cabrera's over a dealership can save you 40–60% on transponder key replacement costs. There's no need for towing, no service department appointment, and no waiting days for a key to be ordered. We bring the solution directly to you with same-day service available throughout the South Bay.

Frequently Asked Questions — Transponder Key Programming

What is a transponder key and does my car have one?

A transponder key contains a microchip embedded in the key head that communicates with your vehicle's immobilizer system via radio frequency. Most cars built after 1995 use transponder keys as a factory anti-theft measure. If your car has an immobilizer system — meaning it won't start with an unrecognized key — you have a transponder key system. Not sure? Call us at (408) 794-8016 and we can help you identify your key type.

Can I use a copy shop to duplicate my transponder key?

A regular key copy shop can cut the physical blade of the key, but they cannot program the transponder chip. Without programming, the cut key will fit the lock and ignition physically, but the car will not start because the immobilizer won't recognize the chip. You need a professional auto locksmith with OBD-II programming equipment — call Cabrera's at (408) 794-8016.

I lost all my transponder keys — can you still help?

Yes. Even if you've lost every key to your vehicle, we can program brand-new transponder keys using your vehicle's VIN and our specialized programming equipment. This process may take longer than a standard duplication, but we handle it all on-site. We'll need proof of vehicle ownership such as your registration or title. Call us at (408) 794-8016 to get started.
