Turn the ignition switch into the "On" position and leave for approximately 30 minutes. The security light will remain flashing for approx. 10-15 minutes. Then, will turn off and the modulator will reset. Then, turn the ignition to the off position take the keys out and the reinsert and start the car. The "security" light at this point will be off. Due to the security modular, the fuel pump is being shut off to control the theft of the car.

Put the key in the ignition and turn it to the on position. Leave in this position for ten minutes. Turn key to off then to start. This should reset the security and the car should start right up.


.You can reset the antitheft system, on your 2003 Chevrolet Cavalier, by removing the fuse. Keep the fuse out for 10 seconds. Replace the fuse to its original slot

GM cars do not have inertia/reset switches.


The 2003 Alero does not have the hour and minute buttons to change the time. The instructions for the clock are also not in the 2003 Alero Owner Handbook either. The steps to change the time:At the top right of the radio there should be two tiny holesInsert a paperclip into one of the holes and hold it thereOnce you hear a beep you should be able to reset the time


When playing with the electrical system to a car, it is important to have a diagram. A diagram for a 2003 Alero can be found in online forums and in maintenance books.


You will have to do a full global reset. To do this, disconnect both of the battery cables for 5 minutes and then tape or hold them together while they are disconnected for another 2 minutes. Reconnect everything and it will be reset.


in the internal fuse box on the back unplug the cables that go into the board. REMEMBER TO MARK WHAT GOES WHERE.

Oil Filter 2003 Alero V6 3.4L part no. 3387


my guess is that it DOES have an alarm system. take off the cover to your fuse panels. if you see a clear plastic recantangle on each side {driver and passenger} you have the anti-theft system and just need the proper remotes to match


Not 100% sure about a 2003, but on a 1998 you reset the security system by locking and unlocking the doors from the outside with you remote key fob. Hope that helps.


Car will not start because I think that anti theft is the only have a key no remote


Probably a problem with you key being worn and the theft lock system not recognizing it, so it thinks you are trying to steal you car because the key is not an exact match to what is programmed into the ignition switch, thus grinding but it will not start!


brake fluid, the clutch works the same way your brakes do.


It should reset by itself, unless there is a problem with the system. Have it checked or check the sensor.


The system is "reset with a scan tool. If the cause of the light is not repaired, it will come back on.The system is "reset with a scan tool. If the cause of the light is not repaired, it will come back on.
