1991 500SL locking system problem.
The car will not unlock when using the fob and when the key is used the security system is set off. yesterday it was working just fine but this morning it will not unlock. As I am not a very car savvy guy, I do not have any idea what the problem could be. suggestions would be much appreciated, thank you.
