I drive a 1990 Lexus Ls-400 v-8 engine. For some reason, Im not able to turn the key to unlock the driverside door. It's happened before, but I was always able to unlock the door in a short time. If the driverside door cant unlock, no matter if you unlock the passenger side, the car wont start. When the lock and key comes together, It's like it unlocks the entire car, including the trunk. I have no Power to start the car without the driver side door being unlocked. Can U help Me?
