I have a P-reg Mazda 626 Executive with one key and NO remote. I have fitted a new battery but every time I connect the terminals the alarm goes off. I have tried locking and unlocking the doors, both from the outside and the inside, both with and without ignition on, but haven't sussed it. Is there a particular sequence I have to use? Many thanks

I've done it before, just can't remember what I did!

You can't, factory only it needs an ECU programming number
