My remote does not work in my 300 and I replaced the battery. I need instructions on how to progam the remote now that I have replaced the battery.
Thanks

 

shouldn't need to reprogram it due to a battery replacement. is this a seperate key fob or built into the key. I have seen a lot of the built in key fobs get a bad connection inside the key. unfortunately to fix that you need a new key or fob. but it will still start the car.
