Pinning for Pick and Bump Resistance?

[s3curity]

Anyone have any thoughts on pinning that will resist lock bumping and picking in general in common locks especially such as Kwikset?

[GWiens2001]

Bumping - use different strength springs, or modify the plug so it has a pin sticking into the keyway from the side as an inactive 'check' pin - if the key (or bump key) does not have a divot/cut at that point in the side of the key, the check pin is forced into a groove or cut in the shell, locking the cylinder. The bump key won't have that cut (especially if you don't tell ANYONE that you have a modified lock, so the lock will never bump open.

Pinning - high-low-high-low-high bittings are typically harder to pick than the standard bittings. But face it - you are talking a Kwikset. Unless you modify the lock with security pins and threading the pin channels, the lock will not be that difficult to pick. But if you do modify the lock as mentioned, it can get pretty fiendish, depending on the modifications you make.

You could also try using the ILCO Bump Halt pins. They are not 100% effective at blocking bumping but they do make it harder, especially if you use more than one pin. They are also more difficult to pick than standard driver pins.

If its your own lock you are using all the time on your house you will have to test it to prove it can be bumped first. If it can be bumped you will have to test it again after modifiation to prove it cant be bumped with the original bump key and a few others just to be sure. The chances are it will not bump after the testing because bumping damages every active part of the lock which in effect increases bump resistance and more importantly reduces the life and reliability of the lock. So if you want to improve bump resisance change the lock if even only to an uncommon profile to reduce availability of the bumpkeys in the first place

Best of all, it costs virtually nothing but your time

Cute idea. Also, for Kwikset put in a #7 pin. Since it is exactly level with the shear line any attempt to bump will only push it above the shear thus confounding the bump process.

If this works then won't using a .315 bottom pin in schlage and making a #10 depth key with my framon also work on schlage locks?

I dont see why it wouldnt make bumping more difficult. Not impossible, just unexpected. Kind of like putting a very heavy stainless steel spring above a '0' length bottom pin. Can normal bumping really get that kind of pin separation?

I've done one masterkey system on a very large building using 12 custom depths instead of the usual 10. (.015 increment and 2-step progression) This maxed out the available pin space on the plug.

It seems like the easiest remedy would be using small ball bearings combined with the top pin springs. I just don't know how small the bearings need to be, as I don't
understand if the bearings need to be small enough to move through the inside of each spring.

Lets face it, any lock that is meant to open can be picked or bypassed at some point. There is no full proof way to secure a lock.

I completely disagree.

Guess you have never heard of Knock-n-lock

Someone tried to break into my house. So I rekeyed all the locks, Thaught I came up with a tough key cut (I could not pick it for a long time). Replaced the springs with a little oversized springs from lab kit. And installed all spool pins in the top. Was impressed when I tested it out for a couple days untill I tried a bump key. !st couple hits opened all the locks. Now I am trying to learn about bump proof will keep looking at postings.

Interesting technology. I can foresee a problem if it fails in locked mode, though...how would you bypass?

Very clever! Might be a problem integrating it into an existing system though-unless you wanted it to work in just a few doors.

That would stop anyone who didn't know about the keys. It would also ensure that you would have to make copies of the keys for them. But I think I would rather sell someone a high security key way instead. Interesting idea, thanks.
