Ill make this quick, i have never been able to lock the doors in my 86.5. Not manually with the key or with the lock button. Is there a way to disable the power lock, so i can least get my doors locked? If not what might be wrong

One problem might be that the switch in the ignition has worn out. Cause the Supra won't allow the doors to lock if the key is still in the ignition. If the switch is worn out the ignition will still think the key is in. Also, you probably already know this, but you have to lift the handle when closing the door or it will keep unlocking. If all else fails pull the fuse till you figure it out.

Ok I tried pulling the fuses for the ignition...no luck, i have no clue how to get to the relays. When the key is in the ignition the dinger is going, when i remove the key it stops, could the igintion still be defective?
If i try to manually push the lock lever from inside it dosen't want to move. I don't know how i can get this thing to manually lock. Please help

It sounds like its door panel pulling time. You'll probably have to get in there and check it out. The locks may be jammed, or linkage messed up. At some point in the cars life, someone may have tried to get into it with a 'slim-jim' and messed it up.

Also your car is old enough to have corrosion. My 87 had a couple of interior door parts on both sides with corrosion. My alarm was going off when I opened the driver's side door. I took apart the door and found corrosion.

It sounds to me like your lock cylinders are bad. The part from Jay Marks Toyota (Champion now) is like $140. You can try to find a couple of good ones in this forum for a lot less.

like $5 max. most junk yard owners have no clue about the value of items and you can talk them down easily.

ok, im gonna come clean, after installed the motor to this car i was testing the power and other things and i hooked a battery up to the terminals under the hood wrong, and i blew a couple visible fuses under the hood and in the cabin fuse box, they have all been replaced, and nothing. My wipers also started acting funky, like with the key on accessory they are on. So i rigges a switch to fix that. But do you think it could be a relay. I have a general idea where it is but don't know how to get to it
