The theft light issue is a good observation. Have you replaced the key tumbler or an ignition component lately? Has there been a lightning storm close very recently?
What the flashing security light is indicating is an attempt to relearn the key you are using.
Turn the key to run position, allow light to flash for 10 minutes, when light stops flashing turn ignition to OFF position for 5 seconds, turn ignition to run position and start over. Do this for 3 consecutive cycles, the the theft system will relearn the key cylinder code and store it once again.
Try that first before you go any further.
Let me know what you find.

Body Control Module (BCM) on both counts. Find a shop in your town that specializes in electrical systems to test it. Beware, these can be intermittent problems, so make sure they keep it until the car does what you have observed. Expect to spend about $450 for the replacment. Dealers quoted me between $700 and $1,100 for the same repair. By the way, a new BCM will probably only last you about 12 months.

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, Try a spare key that is newer or used less. The pins wear down and so do the keys causing security fail. 2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a better rating to help more people on this. Thanks
Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the free affiliate program. Thanks
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.
It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.
