Remote Keyless Entry System Operation - GMC 2007 Yukon XL Owner's Manual

At times you may notice a decrease in operating
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:
•
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
•
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.
•
Check to determine if battery replacement is
necessary. See "Battery Replacement" under
Remote Keyless Entry System Operation on
page 113.
•
If you are still having trouble, see your dealer or
a qualified technician for service.
Remote Keyless Entry System
Operation
The vehicle's doors can be locked and unlocked
from about 3 feet (1 m) up to 65 feet (20 m)
away with the Remote Keyless Entry (RKE)
transmitter.
If your vehicle has the remote start feature you can
also start your vehicle with the RKE transmitter.
The RKE transmitter, with the remote start button,
provides an increased operating range of 195 feet
(60 m) away. However, the operating range may be
less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off
than you were to start it.
There are other conditions which can affect the
performance of the transmitter. See Remote
Keyless Entry System on page 112.
