Cheap Mazda 8C transponder key copy

Total spent:
€10 for 2 keys (with transponders in them) and 2 remote controls. All from junk yard from two different 626s.
€10 for cutting two keys
$7 for two flip keys
About lets say €25 for two sets of key + remote.

The idea is simple - 8C transponder chips are re-usable. These chips are used in almost all models (121, 323, 626, BT-50, Demio, MX-5 (Miata), MPV and Premacy) produced in the late 90s and early 2000s. Procedure shown here is more specific to the 626, but it should be about the same for the others. USE AT YOUR OWN RISK! I'M NOT RESPONSIBLE IF YOU DO ANY DAMAGE TO YOU CAR.
