How can I reset it. I bought another key and ignition (switch) on eBay and still won't start.
Did you have the new key reprogrammed? If you still have the original key, try setting on top of clam shell cover right above the ignition key on column, Try to start engine, If that doesn't work you may need to reflash the the ECM (Eng Control Module) Need more info to be precise

Yes the security system is doing its job it has shut off the fuel and ignition. Try disconnecting the battery for an hour or so to get it to reset. Good luck. Dont forget to rate.
SOURCE: Car wont start, will not reset, security light always on
try locking and unlocking the drivers door with the key. [sometimes if you reach to un lock door through window it it sets off security]

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.

If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.
