The BMW dealer replaced the main module because the locks were malfunctioning. Sometimes the car couldn't be unlocked with the remote key fob button, so I inserted the key into the door lock to open the drivers door. Pressing the LOCK/UNLOCK button on the center console sometimes would not get a response. Even reaching across to manually open the passenger door would not work.
After the repair, all seemed well until I tried the spare key that had not been used by the dealer. It generates no response from the car when the remote "open" is punched. Nor the trunk.
What the h*ll is going on?
