The method of removing the Mazda key anti-theft chip is as follows, 1 without remote control version, to destroy the disassembly! Lay the key flat and slowly scrape the plastic with the blade at a vertical Angle of 90 degrees, so that you do not have to worry about hanging on the chip, because the chip is in the groove of the steel key embryo!
2 With remote control version, buckle the Mazda logo sticker on the back (some do not) remove the screw, pry the key from the end of the key with a blade, you can see!
Remove the key, and when it comes down there's a little square in it, and it just comes off
