Scorpion car alarm?

Hi,

I have inherited my son's car which has Scorpion alarm and remote locking fitted. It is giving me a lot of problems. If I use the remote locking fob after few minutes the alarm goes on and I have difficulty turning it off.

I would like some help either to make it to work or suggest how to disable the alarm but keep the remote locking facility if possible. Has any one got a instruction manual or a circuit diagram
