Alarm control unit?

[NWTony]

It rained, water has gotten into the alarm system so the fob doesn't work and I'm locked out. Does anyone know where the Alarm ECU is? Or has anyone else had this issue?

Answers by PM please!

FYI, this has happened before, but not every time it rains, last time it "cured" itself and driving the car was enough to sort out / dry out the alarm. I'd just like to stop it happening again - and get in my car of course

Two things struggle in the wet on my car - windscreen wipers and the alarm system. Perfect!
