Thanks that was tried at the time but it did nothing, it’s in the list of codes i posted up at the time, I ended up getting new locks and they worked straight away. Could have kicked myself for not thinking that earlier but what are the chances of both being faulty!
I went in a different direction with the alarm, although I did manage to get my home made interior sensors and siren working (though still a bit glitchy), I found out that the alarm wasn’t Cat 1 as required by my insurance so had an aftermarket one fitted.
