The "Easy Entrie V5" is a wonderful bit of kit. It will also cut a key from the data you enter into your laptop, take readings off a key for later use, reproduce almost any key perfectly, cut lots of keys without hassle, and there is a "replay" so you can cut a key multiple times from one reading.
You also don't have to use the clever blanks, it will cut a key from standard blanks if you want it to.
It can't do one of the anti-bump KABA lock with an overhang in the key, it can't do those with ball-bearings, etc. obviously, and it might not do Mul-T-Lock style, and won't do Abloy. Might be possible to do mortice lock keys.
Aside from that, it does everything, whether or not you have the blank!
We cut a few hundred keys without a hitch.
