If he replaced the Ignition switch, he probably fixed your problem correctly, and you got by a lot cheaper than going to a dealer. If he didn't replace the ignition switch, check to see what he actually did, and see if it makes sense. Remember, Passlock problems are caused by either: 1. Ignition Switch 2. Wiring & connectors 3. Body Control Module Doing the 10 minute reset is not worth $300. Why? Because it only takes 10 seconds to turn the ignition on, and 15 seconds to check to see if it worked 15 minutes later.... Total repair time - less than 30 seconds. |

This is only the 2nd time this has happened, but thankfully we came to this site before calling the insurance for towing like we did the last time! We tried #28 where we put the key on the "on" position and waited until the Security light quit blinking. The car didn't turn over, so we went to Plan B: #695 where we oiled the key and IT WORKED!! THANK YOU for sharing your experiences with this apparently-widespread problem.

Replying to: declo_girl (Nov 16, 2009 5:17 pm) "After attempting to start the engine, if the SECURITY light flashes or stays on, wait ten minutes with the key in ON until the light goes off. Then turn the ignition to OFF before attempting to start the engine again." Note that You must turn the ignition to OFF before attempting to start the engine again. Also, What kind of car do you have? Is it one that uses a special key? (look at the side of your key, just below the black plastic "handle". If there is a "+" stamped on the side of the key, then you have a different kind of Passlock system.) Please post back and let us know, as all of us would like to know why 3-in-1 oil on the key works. |

We tried EVERY suggestion on these posts except cutting wires. The only thing that has worked is the 3-1 oil on the key and in the ignition. Othewise it was turn off the key, get out of the car, wait at least 15 minutes. Then it would start. We did the oil about 2 months ago and it hasn't happened again. And it was getting to the point where it happened every single time my husband tried to start it. SO, thanks for the hint. I suggest anyone with the problem give it a try.

If so, can you please post back here and tell us if you have one of the keys that has the resistor embedded in the key, or one that has the chip in the key. You should be able to tell by looking at your key. It will have a "+" stamped on the side of the key. Please post back. |

Hi folks... wow, I've been absent for ages! But I'm ok and still here; just dealing with some medical issues. A special hello to lovemygrandam as he has assisted me late last year with my 2000GT1. An update... My car STILL HAS the security light constantly illuminated steady, but continues to start fine and run fine for me for the last 12 months. I even passed the Massachusetts yearly car insoection with that light on, as it doesn't throw any trouble codes. So my light is still on, and my car runs fine... I'm happy, but sure wish that mod would have worked for me; darn it... As I mentioned many months ago, my Pontiac dealer installed a new cylinder and cut me new keys.. My steady light seemed to start after the new cylinder was put in. Prior to that cylinder, I would have to do the 10 minute wait process.... that's why I had the new cylinder put in. I am still wondering if the mechanic might have jostled a wire somewhere. I was hoping to check that out but have been in some back pain and still haven't done that yet... So my light burns brightly; oh joy !!! But the car runs fine, lol. I have a ton of catching up to do on this long thread. But I'm still here folks... just been down in the dumps a bit. Take care all; I'll start reading this long thread (if I can find where on earth I left off many many months ago). Tommy, from Massachusetts |

I would like to ask those of you who have managed to solve the Passlock Problem on your vehicles, to PLEASE... When you post the solution, include in your post the Year, Make, and Model of your vehicle. It would also be helpful if you tell us whether your key has a "+" stamped on the side of the shaft just below the plastic handle. This will help us to determine whether you are dealing with Passlock I, Passlock II, or some other form of passlock system. GM used three systems, and the solution to problems with each one is different. Post 695 states that using 3 in 1 oil on your key could cure the problem. I'm sure that this works on some vehicles, because some use a resistor embedded in the key, with tiny electrical contacts that must connect when inserting the key. If these get dirty, 3-in-1 oil can clean them and make them work again. With the systems that work with a hall-effect switch and a magnet in the lock cylinder, it's also possible that getting enough 3-in-1 oil into the lock cylinder may wash away metal filings that accumulate near the magnet, thus making that system work again. So my suggestion is Please include your car's make, year, and model when posting |
