Did all 2003 buick Centurys come with keyless remote or was that an option?
It was an option - the only wasy to know for sure is to call the parts deptartment at a buick dealer and give him the VIN # of your car. He can tell by that whether or not your century is equipped for keyless remote.
in your trunk there is a white tag with a black strip on top that lists a bunch of 3 digit codes on it (usually on the bottom side of the trunk liner that covers the spare)- look for code AUO- if it is there , then it has factory keyless entry. If you don't see the tag there, look in the glove box. I hope this helps.
Disagree with AUO code. All 2003 buick centurys came standard with keyless entry. Look it up!
they made a value pkg that didn't have it and I sold a bunch of them new, so no, they DON'T come standard with it- look up the code.
