Mine is a 1989 Eunos so an import . It has a Thatcham Immobiliser fitted no idea when it was fitted though .Fact is I had problems with it and had it removed but left the light flashing so it appears to be working . I never lock my car as I worry they will cut the roof to get in !!  :eek:  :eek:  I also have never fitted expensive Headunits and removable items in the car , anything stolen I have a duplicate at home . Another thing I do is keep only a low level of fuel in it so it would need filling if it was to be driven any distance which brings me to making your car stand out in a crowd . I  live in Minehead , a small town and locals know my car and would be suspicious of it being driven by anyone else .  :cool:

What makes me suspicious I haven't got one is the Two original keys are so small I don't think there's room for a transponder chip!

My old Mk1 Harvard had a seperate two button fob for unlocking the doors.....don't know if it activated/deactivated an immobiliser at the same time?

Didn't the early ones have a button thingy on the dash that you had to touch with a pencil thing to turn the immobiliser off. No transponders in the keys.

Just seen an advert on eBay for a lockset immobilised and it shows a key with the small wing mirror shaped section popped out so I assume that holds the transponder chip!

Mazda advised Thatcham that they started fitting the button on the dash immobiliser with the fob from May 1994 until September 1995 and from September 1995 the cars coming into the country were factory fitted with a new series ECU that connected to a termic immobiliser and an ignition switch antena that required matched keys to start these later cars.

 

Due to stock movements it seems unlikly that there were not a good number of button on the dash immobilisers sold into the market until sometime into early1996.

 

Also it would take a while for the new stock to make it into dealers therefore the factory fitted units would take some time to appear at dealers.
