Changing the Keyless Access with Push Button Start Components

The design of the keyless access with push button start system is to prevent theft even if the various theft deterrent parts change. The parts that can no longer be changed without the possibility of going into a tamper mode are:

• Key fobs
• The engine control module (ECM)
• The remote control door lock receiver (RCDLR)

If you replace the key fobs, the new key fobs must be relearned to the RCDLR, Refer to Transmitter Programming (Domestic and Japan) or Transmitter Programming (Export - Including Canada) . When replacing a RCDLR you must relearn the existing key fobs to the new RCDLR; the ECM must also be put in learn mode to learn the new RCDLR password, Refer to Transmitter Programming (Domestic and Japan) or Transmitter Programming (Export - Including Canada) in Remote Functions and Programming Theft Deterrent System Components (Domestic, Canada, and Japan) or Programming Theft Deterrent System Components (Export) . When replacing an ECM with a new GM SPO part number, that has not learned a vehicle theft deterrent password from any other vehicle, the ECM will learn the RCDLR vehicle theft deterrent password on the first ignition cycle.
