hello fellow s-class owners . my key fob went bad so i bought another key fob from a locksmith & car has been great until this week. it started with my car stalling & ESP & ABS would pop up , hard steering . when i cut it off & would start it again everything would be fine until i changed gears or came to a complete stop & tried going again it would stall. i went to the store & when i was going to park the car stalled & warnings popped up on speedometer i turned the car off & went to lock the doors & none of the buttons on the remote worked so i didn’t think nothing of it and went inside the store. when i came back to the car the key would not turn in the ignition. i thought maybe it would be my key fob deprogrammed but i called my locksmith & had him come check it out & he said the key was still programmed. any tips will help in looking in the right direction!!!! he said it is possible a blown fuse or bad sam module .
