1993Toyota Fourrunner anti-theft system

SOURCE: Car won't start - anti-theft light flashing

it sounds like the immobilizer is faulty. this will shut off the electrical feed to the starter motor. you will need to take it to a garage to get this fixed.

hope this helps.

try this.
PASS LOCK RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.

if the vehicle starts then stops and the anti-theft light is flahing you may need to re-set the pass-key system to do this you will need to atempt to start the vehicle and when it stalls leave the key in that position and watch the anti-theft light. it should flash on and off for about 5 to 10 minutes. when it stops flahing turn the ignition to off then try to restart your vehicle

SOURCE: How to remove or bypass the factory installed anti theft vehicle immobilizer.

in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.

try leaving the key on for 5 to 10 minutes
