Older GM Passkey system

First thing I need to know is what year and model saturn you really have. You listed a 1986 saturn they didn't make the first saturn model year until 1991. They didn't use pass lock sensor's in the S model saturn's until 2000. Let me know so I can help you out.

Even if you have a 1997 saturn there is no pass lock system on that car.I have worked for saturn for over 16yrs and I know my saturn's in 1996 they added the rke module that performed key less entry function with a starter disable no pass lock. In 2000 they added the pass lock and the body control module that operated the pass lock on the S model. The L model came out in 2000 and had a pass lock also. If you tell me which year and model saturn you have and what the problem is I can help you out. Like what it's doing?

So with your door lock's all hooked up do they stay running all the time?If you have a 1996 then you have a rke module that control's the starter disable. Let's start by checking if it could be the starter disable do you have a multimeter or a test light to do some checking?Also have you had the battery tested and made sure the battery cable's are clean and tight.

There is no relearn for the key no pass lock or chip in the key on that car. Make sure your lock's, body, and chime fuse aren't blown in the inside fuse box. After that Make sure all lock's fuse's relay's are in with the lock's going crazy unplug the driver's side lock switch on the door see if the power lock's calm down and work. If they don't also unplug the passenger door lock switch see if the lock's calm down. Most common reason for the lock's to go crazy are the door switches being bad keeping the lock's running all the time. Most of the time it's the drivers door switch. Do you have a key fob we can program?No for testing to see if your rke module is keeping your starter from getting power I posted a diagram of where neutral safety switch on the transmission is. There are two heavy gauge wire's that are red on it. When the key is turned to the start position those two wire's should have battery voltage. Let me know what you find.

If your getting battery voltage to both those red wire's on the neutral safety switch when the key is in the start position then your starter disable is not stopping the starter from operating. Now you need to go to the starter and check the purple wire it should have battery voltage when the switch is in the start position. Then make sure the positive cable to the starter is clean and tight. If all that check's out bad starter.
