Transponders keys are programmed to transmit or receive a predetermined frequency. This frequency is unique to the transponder and the device it is communicating with. The device the transmitter interacts with is usually communicating with radar or sonar. For an automobile key transponder, a device behind the steering wheel receives the signal sent by the transponder’s chip.
The car either unlocks, or even starts in some cases, once the signal is recognized by the device.
Keyless entry transponders are featured in many modern automobiles. In these, the ignition key sticks out of a square transponder case.
If the battery is running low or the transponder key chip has been damaged, the key may not work.
When the transponder is not working, it might mean that is transmitting an unrecognizable signal to the device.
