GMC 2007 Sierra - Manual (Page 117)

At times you may notice a decrease in range. This
is normal for any RKE 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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
under Remote Keyless Entry System
Operation on page 117.
• If you are still having trouble, see your dealer
or a qualified technician for service.
