Pass Key Programming

BCM/PASS-KEY (R) Programming Procedure (Part 1 Of 2):




BCM/PASS-KEY (R) Programming Procedure (Part 2 Of 2):




BCM/PASS-KEY (R) Programming Procedure (Part 3 Of 3):




When an ignition key or the Body Control Module (BCM) is replaced, the BCM must be programmed to accept the resistance value of the new or existing vehicle keys in order to allow PASS-Key(R) operation. When the BCM is replaced, the service replacement BCM is programmed to accept the first PASS-Key(R) resistance value detected. If the BCM is unable to detect a valid PASS-Key(R) resistance value, the BCM will never end the programming sequence and a DTC B2735 will set. The BCM can also be programmed to accept a new PASS-Key(R) code by completing the following BCM/PASS-Key(R) programming procedure.
