I have a 2004 TL and the other day I noticed that I was not able to lock the car with either remote and both lock switches on the front doors were inoperable. I had to manually push down the button on each door to lock the car. Unlocking the car however is normal, I can do it from either remote or use the door switches. It seems that the remotes are OK and I don't think it's a fuse problem. Anyone experience this and if so can you tell me how badly is the dealer going to bang me to fix it ? Thanks.
