10 Minute Re-Learn Procedure (Bravada, Envoy, Envoy XL & Trailblazer)

NOTE: When performing the 10 Minute Re-Learn Procedure, 2 master Passkey® III+ (PK3+) keys are required. If a Gray valet key is learned first, the theft deterrent control module will not allow additional keys to be learned.

NOTE: When performing the 10 Minute Re-Learn Procedure, all previously learned keys will be erased from the theft deterrent control module's memory.

NOTE: Additional keys may be learned immediately after the 10 Minute Re-Learn Procedure.

Use this procedure after replacing any of the following components:

The Passkey® III+ (PK3+) keys.
