Hi,
It seems he has i his wisdom somehow changed the codes when messing around with it.
The only way is to try 4321 which is the default code (user) then reset, r the default enginer code is 1234 then press program then reset.The only other thing then is to get an alarm engineer to crash and re-program the system.
Its always difficult to solve faults from text!
Where abouts in spain are you living as i know an alarm company over there?
Cheers hope this works
