Alright, so I take the car in for some work and get it back from the shop and the smart start and smart entry didn't work afterward, while the fob worked if I pushed the buttons to unlock/lock the door. Been there done that I figured. Surely they had pressed the key button again and disabled the SKS. That was not the case though. With the button in or out it made no difference, the smart start and entry are not working. I've heard it suggested that if the battery goes out maybe it would allow you to use the door lock and unlock button after the battery was too weak to unlock or start the car remotely. I'm not buying that I can unlock the doors with the button with a weak battery but can't start the car with the fab in the car. Any ideas? I can replace the batteries and maybe both batteries got weak at the same time but since the change occured when the car was at the shop and likely had the battery disconnected I am thinking that is too much of a coincidence and that had something to do with it.
