2002 Buick Century Owner's Manual - Page 77

Before your vehicle was shipped from the factory, it was programmed to Mode 3. The mode to which your vehicle was programmed may have been changed since it left the factory. To determine the security feedback unlock mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following: 1. Close all doors and turn the ignition key to RUN. 2. Press and hold the power door lock switch in the unlock position. While holding the door lock switch in the unlock position, press and release the remote keyless entry transmitter UNLOCK button. This will start the customization mode. While in the customization mode, the feature will sound the number of chimes corresponding to the current unlock mode. (If you do not wish to change the current mode, you can either exit the programming mode by following the instructions listed here or program the next feature available on your vehicle.) 3. Each additional press of the remote keyless entry transmitter UNLOCK button will cause your vehicle to advance the unlock mode by one, starting from the current unlock mode. 4. If cycled beyond Mode 4, the vehicle will enter Mode 1. When the door lock switch is released, the vehicle will remain in the most recent unlock mode. The mode you selected is now set. You can either exit the programming mode by following the previous instructions or program the next feature available on your vehicle. Disconnecting the vehicle's battery for up to a year will not change the programmed mode for the lock and unlock security feedback features. 2-13
