Hi, I recently picked up an 06 MCS JCW with one key. The only issue with the car is that the remote key fob doesn't work. I have researched this and tried to pair the key with the car with no luck. However, after hearing that the receiver for the remote was behind the rearview mirror, I put the key fob in that area and it worked! I thought it was the battery but after several 2-3 hour driving sessions I would think the battery should be charged enough to be able to work more than 5 inches from the receiver. Any ideas?
