2011 C70 Key Fobs Not Working After Jump-Start

1158 Views 3 Replies 3 Participants Last post by  LRHolland
I had to have a jump-start the other day and since then neither one of my key fobs works. I put new batteries in both with no change.

I'm guessing I need to have them reprogrammed but wanted to check with y'all before I go down that road. It looks like I can't reprogram them myself.

Thanks for the help.

Take a read through this. Should work after you disconnect the negative terminal to the battery/ turn the key to position II and then reconnect, but follow the steps carefully as described.


That was it!! It worked perfectly. Thank you both for the help!
