Keyless Remote Entry Fob battery replacement on 2005 Saturn Relay?
The battery is very low in our car's keyless remote and needs to be replaced, but there are no screws in the back or any way to access a battery compartment. The dealer said that we'd have to order a new remote, at the cost of nearly $100. A few places online offer a replacement remote, but the cheapest is around $65, and they say you still have to pay the dealer a programming fee to get it to work with your car. How big a scam is this, when a $5 battery replacement would do the trick?!
Any ideas about how to get it open?
Thanks for any help!
