How to set the automatic locking for Buick Excelle?

[DiEvelyn]

Excelle's automatic locking can be set in the car's central control display screen, and it can also be set using the car's lock button. Press the lock button for about 5 seconds until the hazard indicator flashes twice to complete the setup.

Back when I drove the old Excelle, I looked into this. The auto-lock setup is actually super simple. First, power on the car but don't start the engine. Then press and hold the unlock button on the driver's door panel for about 10 seconds until the dashboard flashes the hazard lights. Release the button and immediately press the lock button - you'll hear a 'click' sound confirming it's done. This trick works for most 2005-2012 models. Once set, the doors will automatically lock when driving over 20km/h, which is especially handy when traveling with kids. Some owners report it doesn't work - usually because they messed up the sequence or didn't hold the button long enough.
