How to Start a Buick When the Key Fob Battery is Dead?

Eject the mechanical key from the remote key fob and insert it into the door keyhole to enter the vehicle. Remove the cup holder, place the key fob in the designated slot, press the brake pedal, then push the start button to ignite the engine. Replace with a new battery afterward.

Last time I drove my Buick, I also ran into a dead key fob battery—what a panic! Don't worry, first take out the hidden mechanical key blade inside the fob, insert it into the driver's door handle hole, and twist to open the door. Once inside, place the key fob against the small induction area near the steering wheel (the manual specifies the exact location), then press the start button to fire up the engine. The induction spot may vary across Buick models—for SUVs like the Envision, it's under the cup holder, while sedans like the Regal have it on the side of the console. It never hurts to check the manual. The key fob uses a CR2032 battery, which costs just a few bucks at convenience stores—keep a couple spares to avoid future hassle. Don’t tough it out if this happens; deal with it promptly to avoid getting stranded. If all else fails, call the dealership for roadside assistance.
