It's a clever design, but that key looks extremely flimsy. What if it breaks off in the lock?

I'm all for better locks, but are homes still broken into by picking the lock? Most of what I hear are home invasions, broken windows, or crashed doors.

I can buy an Abloy Protec large format cylinder for about US$90 and make a Schlage or Yale interchangeable cylinder key-in-knob or deadbolt virtually pickproof also. The easy way through my door (or the wall beside it) is with a chainsaw.
I talked to someone who spoke with a thief in prison, and the thief said that the best practical preventative is multi-point locks because most attacks bypass the lock by flexing the door frame. I always thought that Tectus hinges that can allow the door to be flush with the frame on the outside would be nice for door security also.

Is there a lock that could change lever that could be set from a smart phone?

I would rather spend just a few more bucks and buy a Bilock or a current-generation Medeco deadbolt. They don't cost that much more if you shop around. The latter has a proven history over the last few decades and authorized locksmiths can make duplicate keys for you, unlike the Bowley, where only the manufacturer can cut new keys. Since Bowley is new, there's no guarantee they won't go out of business next year and leave you high and dry. The Bowley Kickstarter page makes it sound like buying from an established company is bad, but there are advantages from a hard-earned reputation and substantial corporate assets behind a product.

Unless you plan to make the door frame out of steel plate, I don't see the purpose of a pick proof lock.

A little corrosion in the lock would likely increase the effort to turn the key and allow it to be twisted or break off. While cheap conventional locks are fairly easy to pick, the more expensive ones are quite a challenge. The key in this video also looks like something that would snag threads or other objects in my pocket. I do like the idea of inserting the key and rotating it 180 degrees before inserting it further to engage the pins but I don't like the shape of the key.

That key is actually ULTRA strong!

"Lockman28" Has video review on YouTube showing that it is much stronger than any other key on the market. This is because it's made from very high grade steel.

This is very similar to an earlier and I would suggest a better more robust product idea, which I think was also posted on this site. That being a lock where you are required to put the whole key inside the lock and close a sealed port before you can rotate the mechanism with a handle on the outside i.e. You cannot pick what you cannot get at.
That said this design is still vulnerable to an endoscopic-pick, should one be constructed, for which I claim naming rights.

After watching the demo video it does not change my earlier statement except to say that very rarely indeed to criminals pick locks, preferring quicker and easier targets, windows etc.
But if they are forced to gain entry by getting through this lock then it is not difficult to imagine that a deadbolt sitting proud of the doors surface is vulnerable to being hit from the side (concussive picking) to remove the whole lock so that the drive pin can be turned manually. Oh, and even if you sink this fluch into a door, it better be strong enough to resist being jackhammered through the door.
