1999 Olds Intrigue - How do I disable my security system It won't let me start my car for 10 minutes I don't know what triggers this Some mornings it starts and some it doesn't?

I have a 2002, the same thing happens. I found out that , if you always lock doors with remote, it will stop. Once I did that, it has not done it since. It happened almost once a week, but not in a year.

When it does that turn the key on but not the engine, wait for the security light to stop flashing . once it is solid than turn off key and start car. it worked for me hope it works for you.
