Make a Bump Proof Lock.

[assweasel]

On a 5 pin Weiser, Shalage Or what have you...

Remove the Centre (pin set #3) Pins and spring replace with a long pin you have on hand.

Do not put in a Top spring or pin.

Now when the Bump is tried The new pin shoots up and will always get bound.

Bumping is just a bunch of hype. Scare the public into buying $200 + locks is all. Comes after 911 as well go figure.

I like bypassing locks. Bumping bypasses the lock but it sure is not much of a challenge. I like to match skill and wits against a lock and see who comes out on top.

if the top pin always binds.. then how are you spose to open door with key.

[assweasel]

When the Key is is the long pin is at rest and sits just at or under the sheer line.

When you bump the lock this pin flies upward and gets bound across the sheerline

Sorry was no way to edit above post.

Well i would make a bump key with that pin position removed then

Even the commercial bump proof locks have been proven to be able to be bumped with the correct methods and tools.

Not having a spring on a pin may cause that pin to get stuck very often. Then you have yourself an impregnable lock.

No lock is impossible... We will just have to devise a new method to bypass..

[Kaotik]

impregnable lock! not impossible lock...

I liked the idea.. the name assweasel rocks, but removing a pin will make it that much easier to pick... Besides almost all standard lowes and home depot specials are made pretty much idiot proof so there easy anyway, Just installing them if oyu pay attention you can conjour up about 50 ways to bypass them.. besides anyone bumping your lock will probobly either be a lockie to get you in when your locked out a criminal trying it would do it once or twice jam the lock get mad say the hell with it and kick it in. Or the usual brick through the window.

Leaving the spring at the sheer line will greatly increase the likelihood of the spring getting caught as the cylinder is turned with a key, jamming up the lock and damaging the spring. Good thought, but bad idea.

[assweasel]

Spring? What spring? That pin chamber remains springless.

This is just a thought off the top of the head and was looking for other simple ideas to prevent bumping.

Why??

Well Toool suggest this as the death of this lock type. Not so These locks have been around for quite sometime with little in the way of Mods to them. The design is such that I am sure the Manufacturers will make changes when the need arises.

I prefer Picking myself. Bumping is Ho Hum.... Next Lock.

Ah, OK, I missed that. Carry on...

[LockNewbie21]

Just scrap the idea it wont work, and like i said the locks can be picked easily anyway

[picksmith]

I may be wrong about this but I think the bump key is way more popular in Europe than in the US. Also I think most locks in Europe are mounted upside down. If the lock is mounted upside down this won't work. If I'm wrong, someone from across the pond please correct me. Lol.

Good thought though.

On another note:

The inventor of Mul-T-Lock had a design for an anti bump lock in which there was a special interlocking pin. He had this system set up and was demonstrating it. Basically if you tried to bump the lock the pins would interlock and all attempts at bumping afterwards would not work. I can't remember exactly what happened but i think the bumping caused two pins to interlock and the cylinder would not turn. When the owner got home they would insert their key and try to turn it. The first time it either would not turn or would only slightly turn. The second time they tried to turn it the pins would unlock and their key would work. This would alert the owner that there was a bumping attempt. I think this was supposed to be a special set of pins that would be adaptable to any standard pin tumbler lock. Sorry I can't produce the details but that is what I remember, so I won't state it as a fact until I can find the details. He was looking for a company to buy the patent last I heard.

Of course there are other ways to prevent bumping such as the new Mul-T-Lock key that was mentioned elsewhere in this forum, but I believe you were trying to show a way a regular lock could be made bump proof.

I'm pretty sure you're referring to trap pins. The problem with that is that they render the lock useless afterwards.
