L322 Battery Drain (Interior Alarm)

I've been having problems with battery drain, my battery would drain within a few hours, However i've found out what it is but not sure how to fix, The interior alarm is draining the battery really quickly but if i turn it off by locking the car twice i get no battery drain, How would i resolve this to be able to leave the interior alarm on.

Any Ideas?

Lock it twice.

What's annoying your interior alarm? Why is it working so hard? You got mices?

Nope, I don't have mice lol. It just really annoying that i can't leave the interior alarm on, There is nothing in the car that would make it work harder and the alarm doesn't go off when it's active, I'm at a loss as how to solve.

Maybe a daft question but, is your alarm sounder working ?
If not the alarm going off could be draining your battery.
Can you beg, borrow or steel a interior sensor and swap it to see if your problem goes away ?

The interior sensor is a common cause of battery drain. It may/should be possible to just unplug the interior sensor and job done - or better still, replace it.

As someone else who has a battery drain, could anyone tell me where this interior sensor is located and what it looks like. A picture would be even better
Cheers
