Hello everyone, I'm hoping there is a DIY solution for this.

I have 2 original key fobs and the vehicle is a 2010 T&C Ltd 4.0. I just got a new vehicle battery (still had the original). I drove it afterwards with the suspicious fob. One day later that fob stopped working. At first I thought it was the fob battery so I replaced that. Still didn't work. I took the battery from the good fob and tried it, no go. Then I tried ALL the batteries in the good fob and ALL worked. I tried the bad fob again and noticed the "wrong key" message on my vehicle display.

So far I tried disconnecting the vehicle battery for 10 minutes, but that did nothing. The one fob still won't work.

I have not found ANY T&C drivers with this issue, only some 2013 RAM trucks owners. They had the problem early on in ownership and the only advice was to go to the dealer.

Any ideas? Thanks!

 

Basically a bad key not the battery the battery is used for the remotes the transmitting for unlocking the doors
