vy doors wont lock and alarm keep going off, NOT COOL

[haydenjtaylor]

i have an 03 vy spack and ever since i brought it every now and then when i hit the lock button on my key the "door open warning"(3 quick loud horns) goes off but all my doors are shut my boot is closed and the bonnet is shut so it shouldnt go off really, i took the car back to the dealership i got it from and they coded me new keys, the problem stopped for about 2 week and i was happy with it, but then it just started doing it again, it not as bad as it used to be but can be embarrassing when the horns go off in a basy car park.

if anyone has had the same problem or know what is wont i would much appreciate the help
thanks

By new keys i assume they installed a new BCM (body control module)?

Are you sure the problem isn't one of the door lock actuators? They can become sticky, and if they aren't 100% of the way down the alarm will go off.

nah its not one of the actuators,
and no they didnt install a new BCM, could that be playing up?
