GMC Sierra Owners Manual
Remote Keyless Entry (RKE) System
See Radio Frequency Statement on page 13‑22 for information regarding Part 15 of the Federal Communications Commission (FCC) rules and Industry Canada Standards RSS-GEN/210/220/310.
If there is a decrease in the RKE operating range:
• Check the distance. The transmitter may be too far from the vehicle.
• Check the location. Other vehicles or objects may be blocking the signal.
• Check the transmitter's battery.
See “Battery Replacement” later in this section.
• If the transmitter is still not working correctly, see your dealer or a qualified technician for service.
