Transponder Key Service — FAQ
What is a transponder key and how is it different from a regular key?
A transponder key has a small microchip inside the plastic head. When you insert it into the ignition, the chip sends a coded signal to the car’s immobilizer. If the code doesn’t match, the engine won’t start. A regular metal key has no chip and relies only on the physical cut pattern.
Can you make a transponder key if I have no working key at all?
Yes. We can originate a new transponder key using your vehicle’s VIN and our diagnostic equipment, even when no working key is available.
How many transponder keys can my car support?
Most vehicles support between 4 and 8 programmed keys. The exact number varies by manufacturer. We can check how many slots are available when we connect to your vehicle’s system.
