Master lock anti bumping pin

by **raimundo** » 18 Dec 2007 9:55

this may be old news but i saw a video on You tube from the master lock co about there new anti bumping pin, I was unaware of this pin before seeing that.
It occurs to me that some threads by nubes are about difficulties with master locks, and the video says that they are now putting this pin in all their locks. I suspect that to pick it you must first find this pin and pick it first.
To determine if your master lock has it, a method I would suggest is to hold the lock in your hand with a finger on the yellow brass cylinder end to pin down all the moveables, then shake it near your ear to see if that loose bottom pin is shaking around in there.

Who has picked these knowing that that pin is in there? Tell us about it.

To see the video go to youtube and type master lock anti bumping in the search terms.

The special pin is thicker than the other pins and would seem to take all the pressure from tension, so it must be picked first, or perhaps because the end of the pin is smaller in diameter it won't affect picking. who has the answer, are master locks still just as easy as ever for pickers?

Odd... I was sure there was a thread on here somewhere with some good discussion of this... but I can't find it.

The Master Lock Bump Stop website has some good info on the new pin. I haven't yet had a chance to play with one of these -- but I suspect that it won't have much effect on picking, for the reason you suggest (i.e., the pins under the "bump stop" driver can be easily identified, as they will have no spring tension on them while at rest). Unless they've made several different styles of "bump stop" drivers, picking those pin stacks should actually be easier: simply raise the bottom pin until you start to feel spring tension... and then raise it an additional (constant) extra bit to lift the "bump stop" driver above the shear line. (As with many things, that sounds good in theory, anyhow...) :wink:

I actually spoke with a Master Lock rep at this past CA locksmith convention and they told me that they would not be allowing places like Home Depot to carry the BumpStop padlocks except for locksmiths.

Reason?

They said it's because the stuff they sell at hardware stores are for residential and light duty applications and that the new BumpStop locks are for heavy duty commercial and industrial purposes where the extra security and cost is justified.

I'm not sure if this is true or not but I have periodically stopped by Home Depot now and then since Master was supposed to have released this thing and none of the locks have any BumpStop symbols or anything identifying it as special on the packages.

If this is all true I personally think this is just a way for Master Lock to try to keep these locks out of the hand of hobbyists for as long as possible or at least make it a little more difficult for us to get one so we don't figure out a way to defeat this thing too quickly.

Funny this thread came around today. I just saw this lock last noght in the HL Flake catalog and was curious about it. Prices are from $5.61 to $8.44

For the locksmith yeah. But for the customers, they'll probably be paying double that. Maybe even triple if the shop is in an area thats willing to care about security.

What does it mean when it says "4x more bump resistant" and "the lock is also capable of detecting bump attempts." How does a lock detect bump attempts? Ridiculous.

The "secret" is not nly the bottom pin which is an exagerated spool pin and the top pin or driver which, while not obvious to the naked eye, is cone-shaped enough that if forced as in bumping, it leave a gounge in the stack hole.

The top pin (driver) will only enter the pin stack in one direction. The bottom pin of the stack is no more than a 1,2, or 3 depth.

You would really have to look at Master's video to understand it, but there are definite marks left from bumping attempts. I think there is a shortened version of the video on Youtube

Interesting tho,can see it working if that red pin is loaded with weight :!:

meaning you will need the force of your hand to push the key and turn

Do people even bump these? I have an easier time picking them than bumping them.

Where did you get one?

Me? If you're asking me, I was taking about those master locks in general.

Oh. Guess I'll have to just order it at work.

Don't anyone start the debate again about how Master showed in video footage that the "pins separate on the way down" when being bumped :shock:

Sure they do - to exchange insults in the corridor. The marketing guys can't understand how the scientists can be so dumb. The scientists can't understand how the marketing guys can make such dumb promises to the customers
