That's really cool.
I notice they only show a picture of the mechanical key blank. Wonder how tough a tumbler it is.
But I'd bet that it's tougher than most residential doors/jambs (an admittedly low threshold) so the defeat here is just to put a hooligan tool in the door and open it.
I ended up installing the EZ Armor door frame reinforcement that Revdisk has recommended. If this tumbler is at all good, I really like this concept. If for nothing else than all those times I was 10 miles down the road thinking, "did I lock the damn door?"
I'm kinda interested in these high tech locks because I moved into a new office for work last week, and this is the first time I've resided in a Federal building with any 21st century tech. Our locks do a lot of the gee whiz stuff this one does, and are definitely break-in resistant. I'm one of the people with access to building lock programing, and there are some really cool features for various access programming and use tracking. Sadly, the lock system at work prevents me from locking my coworkers in their offices to prevent them from bugging me.
