I had my alarm serviced last year and the guy changed the engineer's code to one of his choosing without checking with me. He won't tell me the number and despite many promises to come round and change it, he never turns up. I'm hacked off, so I'm going to completely reset the system, and put in a new battery at the same time.
I have done it before, and I've changed the battery too, but a step-by-step guide would be V. helpful. I've got the manual but the instructions aren't the greatest - I think it tells you to disconnect the battery at point but doesn't mention reconnecting it.
Feel free to PM me if you're not comfortable just posting this kind of information in plain sight! (assuming you can PM here...)
