Hi, I have a 2001 Landrover Discovery series 2. Randomly after I lock the car the alarm goes off. I doesn't go off straight away it seem to happen within the next hour or so. It has been happening when I lock it up in the car park at work and sometime later it goes off. It pars to be happening on hot days. Any advice would be appreciated. I tried to find the door switches to check them but I cant locate them. Thankyou in advance.......Tass
