giordon g10 car alarm

Hello, My car alarm has got this annoying feature. Every time i open a door, indicator lights blink for several seconds. I don't want to unplug door trigger input wire, because my security will be reduced. My idea was to turn "door ground trigger" into a signal or a momentary input and then notify car alarm, but i don't know how. Any other suggestions except for buying another car alarm? Thanks a lot.

I have to wonder why your lights blink when you open the door, that's a stupid feature that not everyone wants and I wonder if it can be turned off. The relay diagrams on this site may help you with your idea.

Well, i thought of using electric door lock as a trigger. When opened, it's gonna send a signal that security has been breached. But i don't know if it has the same safety level as door trigger. Perhaps, somebody could open the door without unlocking it.
