Thanks guys, yes disconecting the battery did the trick

Getting a message on my dashboard saying code, a input for a four digit code box comes up on the screen and the alarm goes off, I can stop this with my key buttons but the screen won't change and the car won't start, I've tried the blou tooth code but that don't help, any ideas please

Anybody tell me what the set of Cd or dvd holders are for in the bottom of my centre consul please
