Howard is right... make sure the basics are good; battery starter, voltage, etc.
I had a 2002 impala that would occasionally get a no-start with a flashing security dash light. Wait 15-30 minutes and it might start. I eventually found that there were a lot of GM cars around 2002 that had issues with the PassLock security system. The correct fix is to replace the ignition switch and key.
I ended up bypassing the PassLock system:

Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)

SOURCE: i recently put a new alternator in my 1995 camaro.

The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, 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. Cheap fix: ----- http://vats.likeabigdog.com/ ----- Bypassing the key Never worry again fix: -------- 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

SOURCE: 1994 v6 camaro car wont start because of security light

Without going into a lot of detail, I take it that this Security light gadget is a anti burglar device to really just stop the 'joy-riders' from nicking your vehicle. Follow wires back to were its connected to, the power supply end. [If fuse box, try removing fuse, or is it inserted into a cable bullet? remove from bullet socket]. If unit works by completing a circuit, replace this mechanism [the whole unit], with a new length of correct voltage /ampere type cable inserting [or connecting replacement as other connection is removed, so you will not forget just where the cable came from.

No battery problem either


My guess is that after it ran out of gas, the key was in the forward position for a while and you unknowingly interrupted the antitheft system. Try to reset it.

RELEARN PROCEDURE:
Turn the key on, with the engine OFF.
Try to start the engine, then release the key to ON, Engine will not start.
Watch the security telltale, after about 10 mins, it will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. You must turn the ignition OFF for 30 seconds before attempting to start the vehicle after the 3 cycles. Then start the engine .

My security light is on, on my 97 bonneville, my car wont start does the chip in the key have anything to do with starting it, or the light on?


The chip in the key is not a chip, it is a piece of resistive wire, the key reader See's the resistance of the key is correct and allows the car to start. The common cause of the problem you have is the reader in the ignition lock cylinder. You can't buy that part anymore so you must bypass it, this of course will disable the security system (called the VATS system). Here is how you bypass it, go here to read about the procedure.

Car wont start till i turn key on for 10 minutes


Sounds like a security passcode issue. There is a chip inside the ignition and if your key does not have a chip in it, this is probably the problem. You can bypass the security lock feature but its a pain in the kisser. Unfortunately, that maybe the only solution to bypass the system or you can do nothing except before letting the key go when you start the car make sure it is started.

This car key has the VATS security chip in it. These keys are at least 100 bucks. You can rip into the ignition part and start the car with the wires, but it wont work untill you bypass the SECURITY system. Here is a link about the security. Gives you the 15 possible key chip codes and links to help bypass this system.

Car wont start, the security light is blinking and the car wont start


Your VATS security system is failing. Quick fix, turn key forward 2 clicks till right before it starts. Leave it for 10 minutes. (no less) turn back key and then start again. should be fine. Getting these fixed is about 800 bucks. They sell a bypass for 200 online. I did the "10 minute trick" for over a year, till finally the Computer went. I ended up doing the 200 dollar bypass. Works great, no worries.
Wont crank, wont start, everything else seems fine???? Black chip on key? Read up on this link

Turn ignition key and engine cranks but wont start. Does the security system need to be bypassed or maybe it's a problem with the coded key. Any suggestions?


the security light should be on if its causing the problem,do you hear the fuel pump when you go to start it,should hear a hum for a couple of seconds,does the key have a small plus sighn on it ?
