Why is my car's security light blinking?
Thereof, what does a flashing security light mean?
The Pass-Lock security system can be effected if the battery was disconnected or dead, as well as if something like the ignition switch was replaced. If nothing happens or the engine starts and dies, the security light will be flashing. Wait ten minutes. The flashing light should go off or illuminate without flashing.
Beside above, why is the anti theft light blinking?
Some anti-theft lights blink by default ( a small red light near the dash, for example is there to warn off thieves ). If this is some other type of light then disconnect your battery (negative first then positive) for 30 minutes and reconnect in reverse order (positive then negative). This should reset the computer.
When the security Warning Light is illuminated, that means that the theft-deterrent system may not be working properly. Tip Like all warning lights, the security Warning Light will briefly illuminate when your vehicle is turned on. The light is only a problem if it stays lit when the engine is running.
