Get some WD40 and spray all of the ignition wires, coils.
WD40 can work wonders, gets to places other lubricants can't even imagine :-)
put some wd40 and shve it up yo a$$
Could be a few problems, but start with squirting some WD40 in with one of those thin red tubes.
Sometimes wear on the key and/or ignition barrel can cause this. sometimes the steering lock is under load , and jostleing the wheel while turning the key can help.Try a little squirt of WD40 down the key hole.
Spray powdered graphite into the tumbler. Can be purchsed at a hobbie store and WalMart. Do not use WD40.
You probably need ignition work, but here's a test--spray WD40 on the distributor cap and plug wires and see if things improve.
Edited 6-10-09 Cause is the passlocks contact behind the lock, The female end in the housing section are corroded and a simple solution would be to spray a very small amount of electrical lubricant or wd40 and the the security system should detect the new ignition when inserted.
put the key in the ignition and turn it clockwise
This will sound crazy, but I read it on the Internet and it works. I sprayed WD40 into the ignition after it locked up on me and I had to tow it home; key would not turn and the wheel was locked in place. Put your key in the ignition and whack it hard with a small two by four. It took three quick hits and I reached over and the key turn as if nothing was ever wrong with it. I thought it was a crazy idea until I tried it. Worked like a charm. Good luck
Probably a sticking door switch, give it some wd40. The switch should be where the door hinges.
It already has electronic ignition.
