Help

Not used my car for a month or so, and just been stood on the drive, however i have charged the battery up and started the car, but my blackjax wont take my code, so now it is going off and i cant stop it

It has done this on the odd occasion before and usually after a few minutes sorts itself out and accepts my code again

This time it wont, and its going off on my drive, and i really need to either get it to accept my code, or disable the damn thing, if nothing just to stop the lights flashing and siren from going off all night

PM me please (for obvious reasons)
