if you really wanted to use this you can replace the batteries with a power adapter that has the same amps and volts as the batteries you use

Not particularly secure, but novel. Makes me think of something that one of those "Spy" companies for kids would make.

Thats awesome. This would be horrible for a stoner, you would never be able to remember how to open your door.

should this actually work, what if you want to lock the deadbolt from the inside, it keeps it covered, unless you have to take it off, then put it back on after locking, which is a bit tedious. pretty sweet work in progress though.

It would be too easy to break in to people`s houses with that. You know everyone is just gonna use that one or jingle bells.

So what do you do if you forgot your knock pattern and left your keys inside? Does it lock you out after 3 tries?

True, it is impractical. The good ol` metallic key will be around for awhile.

It seems as safe for locks as a voice activated password to open your door. Someone hears it and can break in any time.

Cool concept, but very impractical.
