Replacing Keys (Without SPS) - United States and Mexico only

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

This procedure should be used without existing learned keys being present.
A total of eight keys may be learned to a single vehicle.
This procedure will only learn the vehicle key information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
If the battery voltage is low, charge the battery before continuing with the procedure.

With an unlearned master vehicle key, turn ON the ignition, with the engine OFF.
Observe the security indicator, after approximately 10 min the indicator will turn off.
Turn OFF the ignition and wait 5 s.
Repeat steps 1 - 3 two more times for a total of 3 cycles or 30 min.

NOTE:

The body control module learns the key transponder information upon the ignition transition from OFF to ON. You must turn the ignition OFF before attempting to start the vehicle.

Start the vehicle. The vehicle has now learned the key transponder information.
Additional keys may be learned using the Adding Keys procedure.
Clear all DTCs.
