How To Reset Security Indicator Light Dead Battery?

Below are the steps to reset the security indicator light dead battery:

Step 1: Reset The Drivers Door Key

Close all of the car’s doors and roll up the windows before getting out. Additionally, shut any rear doors, including the front hood, the rear hatch, and the trunk. Walk away from the vehicle at least ten feet after locking it with the driver’s side lock. Unlock the door after waiting for fifteen minutes; this should reset the security system.

Step 2: Turn On The Key Fob

Numerous manufacturers forbid the automobile from starting after the panic button has been depressed. To reset the immobiliser, hold down the panic button for five seconds.

Next, press the lock button twice and wait ten minutes ten feet away from the car. The security system should then be deactivated by pressing the unlock button twice on the key fob, which should be accompanied by external lights flashing or an audible horn honk. The cancellation of the security light should come after each of these actions. The system has not been reset if this light is blinking while you are trying to start the engine.

Step 3: Turn On The Ignition

The power used by many immobiliser systems must be visible from each power input given by the ignition switch. When the ignition key is inserted and turned to the “on” position, try cranking the engine over, but it won’t start. Wait ten minutes with the key still in the run position, and the security light should blink before going out. Wait five seconds after turning the key off. Follow these instructions three times, each for ten minutes. Any error codes will be cleared after 100 keystrokes, and the car is now prepared to learn the Passlock code again.

Step 4: Remove The Alarm Fuse

Most autos have an alarm fuse in the fuse panel. Remove the fuse to turn off the security system using the owner’s manual. Reinstall the fuse to reactivate the system if the car still won’t start. The immobiliser is being soft rebooted in this manner.

Step 5: Cut The Battery Cord

Due to a voltage surge or a system malfunction, the anti-theft system may occasionally become out of sync. Start by unplugging the negative cable from the battery, wait five minutes, and then plug it back in. As a result, the security system will be able to restart itself hard and reset the alarm protocol, which will assist in the immobiliser starting up in the right order.
