my alarm went off today when i was opening the car. it would not stop sounding even when i tried blipped the key. i managed to start thr car and and i drove it with the alarm sounding. after 5 mins the alarm stopped and i drove one. however when i parked the car only the central locking worked. the light dont flash when i blip the key and the alrm does not activate. the led on the dash flashes at all times now.
