You likely either need to replace the lock cylinder or bypass the security system.

    It is easier to replace the lock cylinder. I'm not sure of the price. I can tell you how to bypass the system, but it takes a little work. Let me know, I can tell you how to replace the cylinder also.

The security light on car wont start


You should try a different key if available. If no other key is available, you can try cleaning the chip embedded in the key

The security light comes on but it wont even turn over


When the light is on, the security feature of immobilizing car-wont allow starting-is active. Pretty difficult and time-consuming to permanently disable the security system, but some have figured it out and published their research over the internet. If yours gets worse, if the light stays on more frequently, you may want it permanently removed. I think it was a ruse by GM and car makers to add cost, and cause more frequent repair visits, but that just me.
Google "disable vehicle security system" or some such, to see results.

Hey have you recently changed your head unit. I have a 2000 s10 2.2 and i recently hardwired my pioneer 4000ub head unit and the security light came on upon not starting. every time you try to start the car while the security light is on it will add 10 minutes onto your time. For the security light not to come on you need to check your wiring. just remember dont keep trying becuase it wont work!!! find the problem and fix it.
