Car alarm is really annoying

DISARM YOUR ALARM WITH YOUR REMOTE

have you checked the fuzes ?

You need remote to lock and unlock doors to reset system.

Interesting, seems alarm has been set-off before<now circuit is ON> and not been re-set back to neutral<re-set circuit to OFF> so when doors are closed, alarm memory retains previous set alarm memory <circuit set to ON>. It'ill go off again whenever door being opened, regardless it have been armed or left open as the memory circuit recognise it still as before alarm set-off<circuit is set ON>.

Solution, 1) Read your car owner's manual in the alarm section, read on how to re-set alarm to neutral if it has been set-off while armed [my experience is by turning the ignition key as if you are going to start the car engine but do not start engine then back to off position, do it 3 times as it will beep after 3rd run]. 2) On 4th run, start the engine, lock all doors then unlock it, 3) Turn off engine, get out from car, lock doors and arm alarm. 4) Dis-arm alarm, open doors and see if it still set-off alarm as before.

If all that doesnot work, go to your local dealer as alarm system has a system fault that can't be fixed without proper equipments.

Follow the instruction on how to accept and mark advise as giving you a core solution. Return a thumb up and praise response. Thank you.

if you unlock the driver door before opening it with the key you can turn the alarm off. Also taking it to a electronics place and having a keyless entry system will bypass the factory alarm as long as you tell them to hook it up and in most cases its less than buying a new factory remote. Also if you dont lock the car with the lock button from the driver door before you close the door the alarm will not arm.

Did you check the alternator? if it is faulty the car will drain all the power from the battery until it goes flat

sounds like the alarm is not disarming

I had this same exact problem in a family member's Saturn. If you are opening the door with the key and not using the key FOB to unlock the doors, then the security system will not allow you to start the car. You will notice when this happens that the dome light will blink and you'll hear the relay in the BCM clicking.

In order to stop the security system from doing this: Make sure the car is locked with the key fob by hitting the lock button. Then hit the unlock button on the key fob once and then once again (I do it out of habit). Then open the driver side door, put the key in and it should start no problem.

it seems that the contact circuit in the driverside door is the problem, it's obviously not the alarm itself others wise the same thing would occure on the passengerside. you have to remove the door panel on the driverside and inspect the wires in that circuit for corrosion which would cause no current to pass between the by pass switch the arms or disarms the alarm. please rate this

put your key in the drivers side from the outside door and turn the key one time to the right to lock your car and two times to unlock it and if your having trouble with the alarm going off open the trunk with the key to disable the alarm if it turned on.
