Turn the alarm off with the remote. The alarm is programmed to go on when power is restored, if power was lost (dead battery, disconnecting cables, etc.).

The alarm tripping is often caused by a bad door or hood switch. Since the hood switch is always exposed to water and corrosion, that one usually goes bad first. Check that out. And no, you can't disable it.

Try having the key in the 'on' position then disconnect the engine battery for two minutes , reconnect and check system.

Is it factory alarm remote if so some times u can take driver side door put Key in turn left n right then it go off if. Not then start car up for a minute let it. Reset if aftermarket alarm then pull fuse under Hood userly they have it running to battery

you have a bad feed censorit tells it when its being burguld or the main brain for alarm look for a local alarm company they will fix or disarm permantly

Hi Sophie Probably just the hood store lid.
Unlock the hood. Pull up the rear screen and open the hood store lid. Slam the hood store lid shut making that the locks on BOTH sides are holding it down and then replace the hood. The alarm will not set correctly unless both the locks are in position. Adrian

Hi I wonder if you can advise me ,my central locking and alarm is very unreliable it keeps making a beep before the ignition goes on and clicking,it sometimes sets the alarm off,Ive had the AA round and theyve told me the car battery is dead,which I appreciate,but think the key hub central locking or alarm is running the battery low does the hand held button need a new battery,or can I take the fuse out for the central locking,dont want to pay 66 quid for a new battery if I can pay 2 quid for a new battery for the central locking button,or demobilize it

Had the same problem. I cleaned the bonnet open/close sensor located at the back left of the engine compartment, and sprayed it with wd40. Worked a treat for me. Another solution is to push you lock button twice. This turns off the interior movement sensor.

my is doing the something because i don't have a remote to the car now when i get out of the car my alarm is going to be on and when i get back in to the car the alarm go off to a start the car. i have to keep one of the door open and if i don't the keys are going to be lock in there. I just get a remote for the car but i have to get someone to get it to work with the car i hoping it going to stop everything. I have a lot of trouble with this car. I just want everything to stop.
