Customer Question

We were given a 1997 Toyota Corolla. The car has an aftermarket Pioneer radio that would not come on. I took the radio out of the dash to make sure all connections were secure. Some were not and I resecured them with appropriate connectors. When I reconnected the battery, the radio still would not come on, but all of my other electrical dash features(headlights, turn signals, A/C fan,etc) do. The big problem though, is that I can't get the key to turn past ACC and to the LOCK position so I can remove the key. The engine goes off, but I can't get the key out of the ignition. When I disconnect the battery again, the key easily moves to the LOCK position and the key slides right out.When I reconnected the wiring, I reconnected each wire according to how I found them. That's when I first figured out I couldn't get the key out.According to the Toyota color coding some of those Pioneer wires were not connected to the correct Toyota radio wires, so I reconnected them again as follows.Toyota: Blue/yellow(battery) to yellow Pioneer
Gray(ignition/accessory) to red Pioneer
Black(ground) to black PioneerStill had the problem.What did I do? How can I fix it?
JA: Soon. I'm trying to find the right Toyota Mechanic for you right now. As soon as they are ready, I will let you know. Have you checked the fuses? Have you checked the bulbs?
Customer: I have checked all the fuses. The radio fuse was missing and I replaced it. Some of my other fuses were the incorrect size and I replaced them with correct size.
JA: Are you hoping to fix this yourself? What have you tried so far?

hello and welcome to just answer and allowing me to assist you. the problem your having is due to a faulty shift lock switch or modal. it is stuck in gear mode and sending a signal to the ignition lock solenoid that it's in gear.It is located in the console with the shiftier mechanism. Hope this helps your problem .If you need further assistance I'll be happy to do so. here are two pics that may help you , the location and what the shift lock controller looks like. check to make sure the switch is OK first on the shift lever.
