Yes, you need the correct resistor chip in the key for the PASS- key system to allow starting and the injectors to work. The computer will sense the correct resistance from the PASS- key and allow car to start.
PASS means Personal Auto Security System. Visit a locksmith who understands the PASS-key security system. Or the dealer. One of them should help you resolve it.

what is the make and model please

actually a pretty easy fix. The pass key computer lost its programming. Put the key in and leave it on with the security light flashing. Just turn off all your accessories and make sure battery is pretty good charge. Anyway after you leave the key on for ten minutes the security light will come on steady so turn key off and right back on and start car. If security light still starts blinking and car stalls then do it again. It will usually work the first time but can take a few times to get it right.

Your vehicle is equipped with the PASS-Key II (Personalized Automotive Security System) theft-deterrent system.
PASS-Key II is a passive theft-deterrent system. It works when you insert or remove the key from the ignition.
PASS-Key II uses a resistor pellet in the ignition key that matches a decoder in your vehicle. When the PASS-Key II system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. For about three minutes, the starter won't
work and fuel won't go to the engine. If someone tries to start your vehicle again or uses another key during this time, the vehicle will not start. This discourages someone from randomly trying different keys with different resistor pellets in an attempt to make a match.

The ignition key must be clean and dry before it's inserted in the ignition or the engine may not start. If the engine does not start and the SECURITY light stays on when you try to start the vehicle, the key may be dirty or wet. Turn the ignition off.

Clean and dry the key. Wait about three minutes and try again. The SECURITY light may remain on during this time. If the starter still won't work, and the key appears to be clean and dry, wait about three minutes and try another ignition key. At this time, you may also want to check the fuses (see "Fuses and Circuit Breakers" in the Index). If the starter won't work with the other key, your vehicle needs service. If your vehicle does start, the first ignition key may be faulty. See your dealer or a locksmith who can service the PASS-Key II.

If you accidentally use a key that has a damaged or missing resistor pellet, the starter won't work. The SECURITY light will flash. But you don't have to wait three minutes before trying another ignition key.

See your dealer or a locksmith who can service the PASS-Key II to have a new key made.

If you're ever driving and the SECURITY light comes on and stays on, you will be able to restart your engine if you turn it off. Your PASS-Key II system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the PASS-Key II system. If you lose or damage a PASS-Key II ignition key, see your dealer or a locksmith who can service PASS-Key II to have a new key made. In an emergency, call the Chevrolet Roadside Assistance Center at 1-800-CHEV-USA or 1-800-243-8872 (In Canada call 1-800-268-6800).
