1999 Pontiac Grand Prix Automatic

I don't know why it happens, but at random times my car will fail to start and a security light flashes on the dash. I have to wait about 10 minutes for this light to go off before trying to start the car again. Normally this only happens once in a while, but the last time it had to go through three cycles before it would start. Why does this happen, and is there a way to by pass this? Thanks.

Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it
