Does the security light flash or come on steady ? Have a lot of thing's on your key ring ? Other key's with transponder inside , Do you know what a transponder is ? The Ignition Key (Transponder) The ignition key for PASS-Key® III equipped vehicles is a typical ignition key using a transponder pellet located in the end of the key. The ignition key transponder value is used in order to determine if a valid ignition key is being used in order to start the vehicle. When the ignition key is inserted into the ignition cylinder and the PASS-Key® III module detects the ignition voltage (the ignition switch is in RUN or START) the module measures the transponder pellet value. The PASS-Key® III module validates this value and performs the following functions: • If the ignition key transponder value is valid, the PASS-Key® III module performs the following (system enable) functions: - The PASS-Key® III module sends a pulse width modulated signal to the PCM to request fuel enable. - The PCM enables the fuel system. - This function enables the engine to start. • If the ignition key transponder value is invalid, the PASS-Key® performs the following (system disable) functions: - The PASS-Key® III module does not send the fuel request signal to the PCM. - The PCM does not enable the fuel system. - This function does not enable the engine to start and run. The engine may start and then stall due to residual fuel in the fuel system. The PASS-Key® III module can identify up to 10 valid key codes to operate the vehicle. Having excess thing's on you ring , including other PASS-Key® III keys , can confuse the computers .
