Fai Securityguard Sgii Remote Key Not Working

[Guest snake]

Hi i have a securityguard sg II

I have two remote keys one of the old rectangle shape keys which works fine and the other is one of the newer keys sort of triangle shape that wont register with the unit.

I also have the manual but this does not tell me how to set the other key to the alarm.

The key was working but stopped and i never really wanted to pay some tech guy 70 quid to re program the remote to the unit.

so can anyone help with directions on how to program the remote to the main unit.

I can get as far as using the key to turn the system off then back on and using the good remote to get all the u1 u2 and all the other displays. but past that im lost.

Thanks
