New Mul-t-lock MT5 (bump-proof lock ?)

[toomush2drink]

The Interactive model is no harder to pick than the classic model - the single difference being that the interactive pin must be lifted to the uncut height, and the inner pin lifted a bit higher.

Please be truthful on this not many can pick open the interactive as easily as the classic if they can pick it at all. Sure it can be picked but it is far from easy. Im getting a little disappointed at the amount of claims on the site at present about "how this is easy and that is easy".All this does is leave beginners feeling a little lacking in confidence when they try to pick a difficult lock.Sure some of the people who visit this site have some exceptional picking ability and others a good knowledge of locks in general but lets not make it sound as easy as making a cup of tea when it is obviously not.

Pah, I can have three Interactive's open before my kettle's even boiled Toomush. The broken kettle, granted...

I agree. Not saying this is the case here but it's pretty obvious some people don't half exaggerate with regards to the ease of picking some locks.

I had to get the reality check in evo as its all getting a little silly and as you and i know its never that easy on a door in the rain with joe public asking how much longer you will be

Can we please agree that a sidebar lock is only "bumpable" if you know the sidebar code, which, IMO, is cheating since you immediately neutralise the sidebar. Without the sidebar code, you are never going to bump it open!!!

Can we please agree that a lock is only bumpable if you know the keyway, which is cheating since you can immediately neutralize the lock. Without knowing the keyway, you are never going to bump it open

I doubt this lock will be sold in MASS quantites here. In most cities lucky enough to have a MT5 dealer, there will probably only be one dealer per city. If you are in two overlapping dealer areas (which would probably only happend in a Metropolis), just take along two bump keys. It's not like you need to carry a keyring with 40 or more keys on it like you would have to with Medeco.

Okay, so this depends on what is meant by the sliders being unique to the dealer.

If the dealer is allocated a set of (hopefully randomly distributed) slider codes, and the machine only allows him to cut from those codes, all's well. Otherwise, we have the Assa Twin situation again, as so often seems to happen.

However, the real question now is: if the sliders provide security, what's the point of the telescoping pins? All having those pins on there does is tempt people to make keying schemes that differ only by the pins, and hence are bumpable. Why not just make a lock with only sliders?

[workstation]

Incidentally, I'm sure the "Alpha spring" is just a ruse, so that their new lock has something patentable in it, for "copy protection". The sliders won't be patentable.

[illusion]

Using only sliders does not provide as much protection, as is offered when it is combined with the telescoping pins characteristic of MTL. Slider locks exist, an example being the Evva 3KS. I do wonder how these locks would respond to overlifting, as is used on worm track type locks?

The Alpha spring would seem to be the new style Interactive element. Probably several different configs to make a wider range of keys.

But is that really the case? Surely you can decode the sliders, then apply the code to your bumpkey, et voila. I realize it's not really that easy, but surely it would be better for the lock to do one thing well.

That sounds interesting; not an expert on this. Do the sliders have to be the sprung for overlifting? They don't appear to be on this lock.

More key differs

I think the smiley wink says it all...

Never mind; at least the pins-in-pins make it look like a Mul-t-lock.

Mul-t-lock last year when the Tool video came out addressed the issue of bumping. They designed new top and bottom pins that would interlock when tension was put on them and with the addition of mushroom pins bumping is not possible. They even flew the guys in the video to Israel and had him try to bump the locks and he could not do it. The lock was certified by the Chech Acreditation Institute as being able to resist bumping. The challenge is for the locksmith to make sure he is using the new pins and to change the pins as the locks come in. That being said, we are not getting customers saying that their locks have been picked by the bump method.

[illusion]

So why do mushrom pins stop bumping???

Well I said that the top pins had been modfied, but apparently I was wrong,

[midnightpro]

the top pins were changed. the first change was the interlocking top and bottom and then interlocking mushroom top pins. The mushroom pins will tilt when pressure isput on them and make it extremely hard to bump. We had a guy that bumped the lock and after we put only one mushroompin in he could not bump it anymore.

[illusion]

Well I don't belive that mushroom pins stop bumping, since well, they get bumped above the sheerline.

Illusion is right, mushroom pins just kind-of resist bumping. That's why you strike the key, then turn it during bumping.

" The lock was certified by the Chech Acreditation Institute as being able to resist bumping. "

Just like the locks that RESIST picking...
