I recently found out that my cobra alarm doesn't lock the doors when i am generatting it! instead when i am locking the doors with the key all the doors are locked. so there is no problem with the central locking system! if you open the doors and the alarm is armed there is no alarm sound but if you get in the car or turn on the engine the alarm sound, starts screamming! i do not have the alarm diagram!!! the model is COBRA 5804. could someone help me please? i already emailed cobra company to send me the diagram but i am still waiting a response!

sounds like a fuse gone on the feed to the C/L depending on the C/L system it is either positive or (Corsa) negative. Basicly the alarm takes the feed and passes a momentary signal to the existing C/L wires to the driver's door motor which in turn opperates the other door(s) and boot.
There should be a bunch of fuses near the alarm, poss, ignition, (some have earth too) left and right indicators and C/L feed.

Sorted?

problem sorted but now i am looking how to make the windows close when i trigger the alarm! anyone?

i think this would be a extra add-on and would need setting up. if you find out let me know i also have a cobra alarm

i am looking for this! i heard that it's noe needed but i am not sure! as soon as i find out, i will let you know! which model is yours?

There is a window closure module available for Cobras which takes it signle from the brown neg pulse wire. I have on on my Mercedes Cosworth.
