Invisible locks ?

[tepo]

I need to find a bulletproof Invisible lock I can use like thison a small wood door , does any one have any suggestions?

[peterb]

That'll be this one then

I think this is the same as the one you linked to. It is Korean in origin (Hyundai). Not cheap, but probably more reliable buying it from Amazon in the UK, rather than eBay from the US.

how secure is the key encryption? presumably it's sufficiently robust that people can't simply open your door with a master fobb like those cars that were in the press recently?

longevity wise, will they still be robust in say 5 years time?

not sure , whats the alternatives ?

[abaxas]

Most important question is 'are they covered by insurance'.

Also remembering that alarms/etc often increase the chance of left, rather than lower it.

Worth checking with your insurance company. Is this intended to be a primary lock or a secondary one? By that I mean one that you would use when you are in the property (to let someone in remotely) or as a primary lock which is the main form of defence?

If it is secondary, there maybe lower cost alternatives, such as an electromagnetic latch plate that releases the main lock although that would have to be fitted carefully so as not to compromise the strength of the door jam.

If you are in (say) a block of flats with a secure common entrance, other security considerations apply. Hacking attacks might be harder (and as these locks are relatively uncommon, a potential attacker may not consider an electronic attack)

How would a locksmith get past that when it fails and you are on the wrong side of the door?

That consideration applies to any form of non- key operated lock though, including mechanical digital locks. The answer is usually some form of brute force solution. (Unless a copy of the code or, in this case, a spare transmitter, has been left with a trusted friend)

Same way a thief will - Find a more vulnerable point of entry and target that.
There are a surprising number of Non-Destructive Entry tools available to the professional locksmith.

its meant to be primary Peter

I would be wary about using it as the sole primary security device. There is a warning led when the battery level falls to a level where they need changing, but if that is ignored, it looks as if it fails open.

It is difficult to assess the strength of the device, but from the illustrations, it seems to be surface mounted, while a conventional mortise lock is mortised into the door which, if done properly, can give extra strength against forcing.

Where it does offer advantages over a conventional lock is its resistance to picking and other forms of physical attack (apart from brute force).

The encryption security is 'probably' OK, although the technical detail is sparse.

You need to assess the risk of a likely attack, and the ability of the lock to resist them.

As I mentioned earlier, you could use a remote latch release in conjunction with a conventional lock, but of course a conventional lock may be vulnerable to picking etc. Or you could use this device like a night latch, good enough for general use, but supplemented by a conventional (mortise) lock for maximum security, for example at night or if you are Albert in the premises.

However, that is a judgement call that only you can make, based on your particular circumstances.

The battery would need to be recharged regularly as the lock is basically for a trapdoor so I wouldnt see the led . The other worry be would be someone stepping on it but there are ways round that i.e. furniture to cover it

An oubliette?

I think the batteries are disposable rather than rechargeable. I don't think the batteries hold the lock closed, they just throw the bolt. Presumably at low voltage, they throw the lock open. I presume the lock is on the closed side of the space the trapdoor gives access to, in which case failing open is essential ( unless the space is occupied....)

A trapdoor? No going Fritzel on us now. Tech specs suggest it opens when battery's low. A bit awkward for your primary means of security!

More like the batcave , a girl has to keep her secrets somewhere

Thinking of a magnetic bolt / pin I can pull through the floor.
