I've been driving a Buick for several years now, and replacing the remote key battery myself is a hassle-free task. Look for the small gap on the back of the remote, then gently pry open the cover with a fingernail or a small screwdriver—don't use too much force to avoid damaging the plastic. When removing the old battery, remember the positive and negative orientation; it's usually a CR2032 model with the positive side facing up. After inserting the new battery, snap the cover back on until you hear a 'click.' Test the buttons—if the red light turns on, you've succeeded. It's recommended to replace the battery every two years, and you can save money by buying CR2032 batteries online for just a few dollars. Note that some Buick models come with flip-out keys, so make sure to pop out the key first before proceeding to avoid unnecessary hassle and make the process easier.
