Key turns and NOTHING happens. It has to do with the onboard security system. HELP
Depending on the year, you could have either a problem with the small wires that run behind the ignition switch and recognize the PASS-Key system chip in the key, or you could have a larger problem with the ECM. You will have to have this towed and checked out fully by a mechanic to get a complete answer.
This is a common problem on GM vehicles. I have been dealing with these systems for years. Through much trial and error i have found that BYPASSING these systems is alot more cost effective than trying to diagnose and fix them. The cost is too high and mechanics tend to replace as many things as they can before fixing it. Here is a link to educate and guide you in the right direction. This IS something you can fix yourself and once bypassed will NEVER be an issue again. Check out this link and read it carefully. Save some money and do it yourself http://vatspasslockpasskeysecurityhelp.yolasite.com/
How to bypass security without the key
Turn ignition on
Try turning you ignition switch on , without engaging the starter, and leaving it on for 10 mins, then turn it off for 1 min. That should re-set you security lockout. It should then start normally. Works sometimes, not always.
