I had to replace a keyless remote for my 2001 dakota. I found one off od E-bay then I had to program it using the programing sequence in the owners manual. It was really simple. I only paid something like ten buck for the remote and have had no problems.
how do you program a keyless entry remote to a 2000 Pontiac grandprix programyourremote.com (program your remote.com)
go to http://www.programyourremote.com/ they have programs for many makes and models
Try the mirror control.
Open the keyless remote and you will see the battery take it out and replace it with the same size.
