Ok basically my key fob just randomly stopped opening an locking the car last Thursday so I was baffled I then on the same day thought I could open an start with jus the key. So I unlocked the car with the key an boom my alarm starts going off in a blind panic I popped the bonnet an disconnect my battery the alarm went off for another 2min an shut off. So I've left it unlocked an ordered a new battery today for my fob. So the new Lil battery came today so happy I installed it then I went outside to my car plug the battery back then the hazard lights flashed for about 15seconds then the siren went off with the lights my fob still wasn't doing anything what do I do I've hear of some alarm sequence but don't know it! I'm beyond ****ed off now just want my car back! I never had any alarm issues before!
