Master Lock NightWatch Deadbolts

[lockedin]

I saw this while browsing the Master Lock door hardware site. I thought it was pretty cool, but it still leaves an unauthorized person with a copy of the key open to entering when nobody is home. I was wondering what you guys thought:

One last thing-- I must warn you that the video is one of the cheesiest things I've seen.

"Master Lock - A name you've come to rely upon for quality and innovation"

Is that so?

We have this system in the UK, and it's been around for a while. You slide down a small button and no key will operate it, untill you deactivate it.

If it could stop people getting unauthorised keys in the first place I think it'd be a far better idea.

Wow,

I actually have to say that the idea is great for night time use when you're home to pull the red thing out, but obviously anyone with a key like an ex room mate who comes back during the day when you're at work, would not be stopped.

I also have a glass window so I have keys on both sides. I wish they'd invent something that I could turn my inside key 360 degrees and deadlock the outside keyhole from accepting a key or freespinning like that. (but I do have glass so, they could just break it and undeadlock the lock with their key)

And If it's possible to pull out the Master core and put in a Medeco or even a Schlage, dare I say I'd recommend it for people with solid (non-windowed) doors. I think it's a cool idea.

Thanks for sharing that link that was interesting,

I saw one at Target the other day, meant to pick it up when I went back the next time but they had run out... I understand the principle but how exactly does it work? I understand that by pulling the bolt you disengage it but how does that work?

[Octillion]

I'm guessing that it just pulls the axle away from the lock cylinder, so that with a key the cylinder will just freely rotate, unable to disengage the deadbolt.

I was amused with the disney-esque production of this thing. The lock was pretty cool though - it would be nice if they could make something that was day-guard watch though, I'm quite positive nobody is going to try and get in while I am at home. It is when I am not at home that I generally worry - anyways.

Hi undeadspacehippie,

I was just thinking about what you said about a daywatch mode, and if you mean something so when you go to work you can make the keyway freespin until you get home..

hmm.. I like playing with motors, servos and solenoids... and I'm wondering if you could buy a keyless vehicle entry system on ebay, buy a door solenoid for it, and attach the solenoid to the door with some kind of plate that would slide between the latch and door (but still allow the latch to turn left and right) then you could walk outside, use the key to lock the door, then use the alarm remote to pop the latch away from the door, disabling the keyway.

When you get home, press the remote, solenoid (somehow attached to latch) pushes latch back in, key works, door opens, voila!

I feel the creative juices flowing...

Its pretty smple how this works. You know how most cheap double sided deadboltss have a square thing that goes inside another square thing in order to link the two sides. That square thing goes through the part to pull the bolt in or push it out in the doorframe. Well I think its basically the same thing, except the thumbturn thing pulls out, which effectively disconnects the square thing from the other square thing. (That didnt make sense, I know)

In Texas, at least in apartment buildings, all units have to have this interesting device known as a night bolt. No lock, no keyway, no nothing... on the outside. When it's thrown, the only way you're opening the door from the outside is a Hooligan prybar or ram tool.

And that makes a lot of noise, which is useful for us Texan gun owners

This is quite a good idea, if an obvious one. I love the video.

I would like to see a form of cylinder, or, ideally, of multi-point boltwork that combines the three main options:

unlocked from the inside without key, from the outside not at all (e.g. a common bolt)
unlocked from the inside without key, from the outside with key (e.g. deadbolt with thumbturn)
unlocked from the inside with key, from the outside with key (e.g. lever mortice lock)

Obviously, there are other permutations, but these are the ones that seem useful in a domestic context.

Come to think of it, there's also "unlocked from inside not at all, from outside with key".

You get this if you double-lock a single-cylinder nightlatch, such as an Ingersoll.
