I have a problem with starting my car. I have a brand new battery battery cable and starter. I have the key with the chip in it. I have tested this problem and after being told by the dealer that if the car does not start on the first try, it has a five minute security delay. I used my key and had numerous times that the car would not start. I also used my wife's key, which is not as worn as mine. The dealer says that they have replaced very few key cyladers on the column. With using both keys and the one key being practically new, I believe that leads to the cylander not reading the key code correctly. However, I am concerned that possibly it may be a worn linkage from the key switch to the switch on the column and I am wondering if failure for it to start from that would enact the five minute delay. So my belief is, that it is the key cylander not properly reading the key due the reading devices being to far apart from seven years of wear. If anyone has come across this problem and solved it, please let me know what your solution was. If it was acutally the key cylander or something else. Any help would be appreciated.

Thanks

I would rather think the cylinder is bad than any other part of the pass key system. We rarley see a pass key module go bad, but the cylinders tend to go out on them. The two leads the hook into the back of the cylinder usually seperate creating a no start or an intermittent start.

The cylinder is $50.00
and you will need to buy two new keys as they will be cut differently, but the passkey number will remain the same.
The keys are roughly $25.00 each/

Good luck with it.

Can you believe that although their design sucks, all you have to do is spray WD-40 into your key cylander on your column. The two pressure points that connect to each side of your key get trash, dirt, lint or whatever in them and do not come all the way out. Therefore, you get intermittent failure to contact/read the key. Spraying WD-40 and inserting and removing the key loosens up the contacts. I have not had any problems since. Another nice tidbit of information!!! Take your key to radio shack and have them put an OHMS meter on your key and tell you the resistance factor. Then buy that resister from them. Keep the resister in your glove box. There are two wires. One for each tumbler on each side of the key cylander. Another great design factor. They used a wire about the size of your hair...one hair. A common problem, the wire breaks and you can not start your car. Then you pull out your trusty resister from the glove box and go under your steering column on the floor and look for the wire harness coming out of the steering column. Look for a semi fat orange sheeth with the two wires inside. Cut the wires, install one wire on each end of the resister and you have now bypassed the stupid key system. And now your car will start and you can buy regular keys now. I hope this helps someone else that is having problems with the sorry engineering designs of the Chevrolet designers.
