Hi,
I have fitted a remote locking kit to my wifes 1995 5dr Corsa. It had full central locking on the key, and the factory fitted alarm which is set when the drivers door is deadlocked.
Is there any way to set the alarm when I lock the doors with the remote? I don't really care about remote deadlocks, but having the alarm set would be nice. I managed to blow a diode in the central locking unit when I was 'playing' with the alarm/central locking but fortunately managed to replace it and everything seems to work again 
I am not interested in adding a third party alarm, I really just want to make use of the factory one if possible. Has anyone done this or know how I could wire it to make it work?
Many thanks,
Nick

all you need to do is find the wire on the deadlock circuit that sends the trigger to the alarm to activate it, find out whether its a negative or positive trigger, and connect this wire to the appropriate switched output from the central locking when its activated.

Thanks for your reply.
I think I found the wire that the deadlock circuit switches, but it doesn't appear to be straight forward (well to me anyway). When I was 'playing' with the CL module, I was shorting this wire, which seemed to operate the deadlocks, but then I frazzled the diode  Maybe that was coz it is positive triggered? I think the alarm might be a bit more clever than a simple set/unset (only guessing though)? I have been using a multimeter which can be a bit misleading when watching pulses, maybe a bulb and some wire might be better - but then I don't know how I would distingish between floating and ground? What do other people use to diagnose this type of thing - can't imagine many people have an oscilloscope 
Cheers,
Nick

when the deadlocks are activated, just test the voltage on that wire. Its got to be a permanent voltage to keep the alarm active. Stuff like that wont be more clever i doubt.
