I am not sure but if you find out PLEASE POST it here I am having the exact same problem and was looking for an answer also!!! It will start sometimes I have had it in the shop several times and it starts perfect for them almost everytime.. they have ran diagonistic test on it and it shows NOTHING is wrong I have gotten a new key with the same code in it (cost 47.00) not the problem, I put a new starter on it they told me that was the problem NOPE it still did it... I put a new battery in it NOPE.. New spark plugs NOPE.. New ignition switch NOPE... I have tried almost everything and still nothing!!! It has to be something simple but NO ONE can seem to find it ... I LOVE my car it is one of the BEST I have ever owned as far as a GREAT riding vehicle just this crazy security problem!!! THANK YOU
I had the EXACT same problems with my 1995 LeSabre. My mechanic disconnected my remote starter and the automatic door/trunk locks, and it starts up fine now--ALL THE TIME! I cannot use my remote starter anymore, and I have to unlock my doors and trunk with a key, but the car starts up perfectly every time! My repair bill was only $65.00!
I am currently having the same problem with my 95 LeSabre. I have been told to replace the ignition lock cylinder because the problem could be in the wires running to the VATS system from the ignition. I have also been told it could be the VATS system itself. Well I found a site that give you the ability to bypass the system!! I haven't tried it yet but think I'm going to. Here is the link:

You can't bypass or reset security system, bring it to the dealer.
Supposedly there are bypass modules....some are so that the remote start systems can function with the security system in the car....others are just strictly to bypass the security system intirely. I have seen some websites that sell these modules such as Ebay but there are some more specific car sites that sell them too. I have read a few things on this recently and it looks as though GM has used the Passkey I, II and III systems. The year, make and model of the car depends on what system was used and what type of bypass you will need.
You might have to bypass the security system or replace it. GM used the Passkey I, II and III security systems.....bypass kits for these can be found on Ebay and some other car websites.
