how do you change the battery for your keyless remote?
my aleros panic button works but rhe locks and trunk dont. new battery or reprogram?

There is a notch in the side of the remote. Use a dime to pop the cover off. The remote should take a CR2032 watch-type battery. They run about $3.00. Best place to find them is at a pharmacy. Good luck.

you may have to hold down two of the buttons while beside the car for a few seconds, after changing the battery. It should say on the inside of the lid or cover or whatever you wanna call the thing.
