Vehicle Theft Security Key Transponder, with Fob Integrated Key

Vehicle Theft Security Key Transponder, with Fob Integrated Key

Description

The remote keyless entry fob integrated key uses a transponder chip that is integral to the circuit board of the integrated ignition key to communicate with the wireless ignition node. Ignition keys are supplied with the vehicle when it is shipped from the factory.

Operation

Each FOBIK has a unique transponder identification code permanently programmed into it by the manufacturer. Likewise, WIN has a unique "Secret Key" code programmed into it by the manufacturer as well. When a FOBIK is programmed into the memory of the WIN, the WIN stores the transponder identification code from the FOBIK, and the FOBIK learns the "Secret Key" code from the WIN. Once the FOBIK learns the "Secret Key" code of the WIN, it is also permanently programmed into the transponder's memory. Therefore, blank keys for the WIN must be programmed by the WIN. Refer to => [ Vehicle Theft Security Key Transponder with Fob Integrated Key, Programming ] Vehicle Theft Security Key Transponder with Fob Integrated Key, Programming.

The FOBIK transponder is within the range of the WIN transceiver antenna ring when it is inserted into the ignition WIN. When the ignition switch is turned to the ON position, the WIN communicates with the FOBIK via a radio frequency signal. The WIN will determine if a valid key is present based on the information it receives from the FOBIK. If a valid key is detected, that fact is communicated to the PCM via the PCI Bus and the vehicle is allowed to continue running. If an invalid key is received by the PCM or no status at all is communicated, the vehicle will stall after two (2) seconds of running. The indicator light will be flashing at this point. The FOBIK transponder can not be repaired. If it is faulty or damaged, it must be replaced.

Common communication problem:

• Two transponder keys too close together.

Solid indicator that there is a system failure.

• Loss of PCM communication.

• Failed antenna circuit.
