PROGRAMMING A NEW THEFT DETERRENT MODULE
IMPORTANT: Any new PASS-Key II Theft Deterrent Module will automatically program to the resistance of the key (or interrogator setting) being
used at the first ignition "ON" cycle. This can only be done once for the life of the module.
New modules are unprogrammed. Before the system will function properly after a new module has been installed, it must be programmed to the code
that matches the customer1s keys. Programming a new module is very simple:
1. Install the new, unprogrammed module.
2. Insert one of the customer's keys in the ignition lock cylinder and turn it to the "ON" position. It's a good idea to start the Engine at this time to
verify system operation.
3. Observe the "PASSKEY" indicator Lamp:
The indicator lamp should light for about five seconds and then go out. If the wiring or contacts to the Key Resistance Pellet or the key is
defective or intermittent and a new module is installed, the Engine will start but the "PASSKEY" indicator will flash at a rate of one flash
per second until the Ignition Switch is turned off. This indicates that the module did not program and that the system components, wiring
and contacts should be checked for a fault.
IMPORTANT: Before connecting the interrogrator to the ignition lock cylinder circuit, always verify vehicle key code and set the code into the
interrogrator using the "key code" knob. This will prevent programming an unprogrammed module with an undesired key code.
