After sitting for a while, my car's battery became dead. After a replacement arrived none of the remotes or tpms would work. Finially i took it to the dealer and they tried reprogramming the keyless entry and tpms but couldn't get the car to recognize thee remotes or tpms. What seems to be the problem. They said they could order a replacement reciever for $100 but i want to find the part online cheeper. Anyone have the same problem? Any suggestions? Anyone know what that part would be called?
