Transponder Keys

What is a Transponder key?

Transponder keys may also be called "chip keys". Transponder keys are automotive ignition keys with signal-emitting circuits built inside.

Jim's Locksmiths can duplicate most Transponder Car Keys for much less than the cost of an original.

How a Transponder key works

When the key is turned in the ignition cylinder, the car's computer transmits a radio signal to the transponder circuit. The circuit has no battery; it is energized by the radio signal itself. The circuit typically has a computer chip that is programmed to respond by sending a coded signal back to the car's computer. Many cars immobilize if intruders use the wrong key. Chip Keys successfully protect cars from theft in two ways: forcing the ignition cylinder won't start the car, and the keys are difficult to duplicate. This is why chip keys are popular in modern cars and help decrease car theft.
