As I understand it, this is a delicate matter, you can make a lot of keys and chips for entrances, car keys here. There are practically no problems, but here is the main condition of the master, if there is a problem, you need to see the lock or the core, although after thinking about it, this is understandable. The equipment can be seen that it is branded, the prices are lower than in the advertised company "Sam master" and the attitude is different, do not let go))
I recommend it if you want to do it the first time and at a reasonable price.
