To reset the anti-theft system, follow these steps:
1. You have a little red light on your dashboard-press it to disarm the alarm
2. Try turning the key and moving the shift from park to drive and back, then try starting it again
3. Disconnect the battery and let it breathe for 20 minutes and more, and reconnect it, that may do the trick
4. If all else fails, you may need to go down to the dealership to reprogram the key
SOURCE: how do you reset the anti theft system
Try disconnecting your battery cables then wait about 10 minutes. The computer should reset itself. Reconnect the wires to the battery. It is normal for the theft light to blink about every 5 seconds when the ignition key is out or in the off position. This means the system is armed and working properly. Hope this helps. God bless!

Put the key in the ignition, and turn forward all the way just before cranking. Then within 5 seconds, locate, press and hold in the valet/overide button, found under the dash area, (push button, spring loaded)until the installed LED (the blinking light) in your dash area goes on solid, and the siren chirps once (your valet switch might be the toggle (on/off) type. in this case, key on, flip switch in opposite direction, then turn the key off.).
This should reset the alarm, and resetthe grounded relay on the starter wire, allowing you to start the engine.
At this point, the only thing working would be the keyless entry from the alarm, if it came equipped that way.
Just Repeat these steps to place itback to usable armed mode. You may get 2 chirps, confirming it,and the lights may flash twice as well. That should do it.

A factory anti-theft system does not have a reset button.
Have you tried a different key?

Turn the vehicle on. The engine does not need to be running but the ignition should be on to power the stereo.
