I drive a 1999 Mazda SOHO 1.4i ( http://www.lds.za.net/mazda_soho.htm
It seems like the factory fitted Alarm system is not "working" anymore, since it does not deactivate.
I have that computerchip build into the key , and when I turn the ignition, it send some code to the car. Hope this helps
PLEASE could someone help, as I can not drive the car now ;-)
