The Canadian immobilizer standard requires
Canadian owners to see their GM dealer

transmitter is not available. United States
owners are permitted to match a new transmitter
to their vehicle when a recognized transmitter
is not available. The procedure will require
three ten minute cycles to complete the matching
process. Do the following:
1. The vehicle must be off.
2. Place the new, unrecognized transmitter in
the glove box transmitter pocket with the
buttons facing to the right.
