I recently bought a 1998 1.4 auto corsa b CDX i noticed it had a toad alarm previously fitted after some investigation it was missing the main computer
so i bought a cheap chinese alarm had that fitted so now i have a shock sensor alarm fitted with remote central locking working on the fob.
I was googling my car and came across that its suppose to have deadlocks so i went outside to see if i could get them to work turned key in door and pulled it out when it was horisantal with the window down and i could still pull up the door button so i guess it doesnt work. Whilst doing this the factory alarm went off that i didnt even know it had
so now im wondering what alarm is best to use? also i know how to turn on and off the ultrasonic sensors for the factory alarm but how do i know if there on or off? thanks in advance for any help really appreciated
