Matching Transmitter(S) To Your Vehicle - GMC 2000 Safari Owner's Manual

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
D
Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.
D
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.
D
Check to determine if battery replacement or
transmitter resynchronization is necessary.
See the instructions that follow.
D
If you're still having trouble, see your dealer or
a qualified technician for service.

Matching Transmitter(s) To Your Vehicle

Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only two transmitters
matched to it.
