Replaced car battery, now keyless remotes don’t work. They do start the car, but cannot lock/unlock remotely. Yes–fob batteries are good. Thx
You may need to reconnect the fobs to the car. That requires a scan tool from the dealer. Since there are no more Saab dealers you need to search for Saab parts and service on google and see where the nearest Saab service is to you.
Or try a locksmith.
Maybe this helps:
