Disarming an Armed System/Silencing an Alarm

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

If system arming has been requested by the power door lock switch or the keyless entry transmitter, it must be disarmed.

IMPORTANT: Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent (CTD) arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.

To disarm the CTD system in standby mode, perform one of the following:
- Press the UNLOCK button on the keyless entry transmitter.
- Insert a valid key into the ignition and switch to the ON position.
To disarm the CTD system in the armed mode (non-event) or when activated (during an alarm event):
- Press the UNLOCK button on the keyless entry transmitter.
- Insert a valid key into the ignition and switch to the ON position
