Lock bumping can be a quick and effective way to get a lock open. You can typically thwart these techniques with one simple change and that is adding zero lift pins. Zero lift pins are keypins that naturally sit at the shearline and they do a great job at preventing lock picking and lock bumping.
Zero lift pins are easily overset during single pin picking and during lock bumping they prevent the plug from turning because they are too tall.
The example I used in this video was on a Kwikset lock. Kwikset locks typically come with keypin lengths 1-6 and the zero lift pin is a 7. A Kwikset bump key comes cut to the maximal depth of 6 for each key pin. When you insert the bump key into the lock with zero lift pins, that keypin will be overset and the lock will not be able to e opened.
Being able to implement this is as easy as changing out 1 keypin and having a new key made.
This technique can be overcome by making a bumpkey cut to the zero lift pins height or if known which chamber the zero lift keypin is in, you can file that part of the bump key down.
This is a quick and effective way to increase your security and I hope it helps!

Finally came across a video that explains the anti bump mechanism. Thanks!
thanks for checking it out
Great tip! I used schlage F series drivers as T pins. As long as the core has construction holes, and put them pointed down with a wafer so with the key it works great and when picked it drops into the construction holes.
And locks up the lock.
Yeah it disables the lock, but I can enter in another way and fix it from inside. But ultimately it's just another way to secure a Kwikset.
I have seen that done before and that is a cool idea as well. It is interesting how some small changes can make a big difference.
I would pick all your locks so no one could get in.... lol
I saw that video and what that does when a pick/bump is tried it makes the lock permanently in operable meaning you can't even use a key to get in afterwards, not sure how you get in or get it off but it sounds like more trouble in the end for the owner!
@@tweetiebird Howdy,
Well as long as the other commenter didn't pick all my locks then I go in the back door and then take the lock apart and pop the cap from the bible and then free up the t-pins.
So not for the non lock person.
But it might mean a call to a locksmith and that is much better than a burglary.
Hope this helps
Also the zero lift pin prevents raking. good idea.
Thank you for checking it out
Man is this a great video I mean truly it took me a couple times to watch it for me to totally grasp the gravity of how cool a number seven pin is thank you thank you thank you
I’m blown away, so easy to do. Thanks for the info. 4:37
I never thought of that. I just add security pins normally.😎✌
I find it to be a fun idea, thank you for the kind words!
Enjoy all your videos! You’re very knowledgeable, helpful and very much underrated in Lock Sport! Also this might sound weird but your intro music is so cool and catchy too! Lol Happy Picking!
Thank you for the kind words
i did that same thing in 2004 when i saw my first bumping video. altho instead of putting the set pin in one i put it in number 4 chamber. works great. also i used a five pin lock. with a number 6 pin in chamber four.. that way when you use a 5 depth bump key that pin goes above the shear line.same thing as you have.
Thanks for sharing!
What am I watching and why do I enjoy it so much ? ;)
Thanks for checking it out! It is a fun and easy way to improve the security of your lock.
Great idea!!
Thank you for checking it out
This was very helpful and appears easy to do too.
Thank you for checking it out
Excellent advice my friend makes perfect sense. Thanks for sharing 😎
SUNCOAST PICKER Thank you for the kind words!
An extra low cut in position 1 would make this key more susceptible to breaking at that spot, especially since it makes the key harder to get in and out of the keyway. Another location may work better in the long run. This technique could also be applied to many other locks but with the same risk. As long as you can find a pin that reaches the sheer line and can file down that position of the key to match, it should work just fine.
I picked posistion 1 because it makes it so easy to overset and also I happened to already have a key with a 6 cut there so I only needed to file a little bit.
I think putting the 7 cut in 4 followed by a short keypin in 5 would make a tough pick and maybe stabilize the key more like you said.
Thanks for the input!
A key (lol) bit of information here is that way back when bump keys weren't made commercially, the key was(at least where I'm from) referred to as just a "777" key, the term "bump" became common a couple years after it became commonplace in a pickers toolkit.
I find it odd that you'd never have seen a bump key cut down to 7, since this used to be the single most common bump key.
Thanks for sharing and yes you do have a fair point. A proper bump key should be cut down to the maximal depth like the uncommon 7 depth on Kwikset. For whatever reason, I have ran into a few sets of bump keys for Kwikset which did not do that.
Either way, thank you for sharing your input and perspective! :)
Interesting and I like the deathlike you provided to back up your point :-)
Lock Noob thank you for the kind words :-)
I’ve noticed that with Schlage and Kwikset keyways you can see what length the first pin is by just looking into the front keyway opening. Would there be any advantage to putting the 7 pin in the second or third position instead? Might make it more difficult for a picker to determine the problem, and slightly more pick resistant.
I agree in a way. I guess his point is valid but I'm sure you can move that gate keeper. It's a sacrifice of one pin to stop a rapid entry technique
I think if you moved it into position 4 and put a really short keypin in 5 that could make for an increased challenge when it comes to SPP.
This isn't a full proof method but it is a cool idea on how one simple change can really make a difference on stopping one technique of rapid entry.
Loren Koehler your right, that's why number 4 chamber is better. you can not see the pin and attempt to bypass it. and i find it only works for bumping. top of the key way tension and a very deep hook gets you in. unless you use security pins in the other chambers that take longer to pick opened.
Thanks for sharing!
Can you use this on a programmable Kwikset lock
I don't believe so
Thank you. Good video, I enjoyed it.
Glad you enjoyed it
were did you get your wand/pick from it looks nice?
charles klein Robert Fisher. Look back a few videos I did a review on them and how to contact him if you're interested
now that was interesting and i thought doubling springs on 1 or 2 of the pins would be the way to do vs bump keys.
That can help but this way is an interesting approach
Cool idea. Thanks for sharing
Thank you for the kind words!
I have 2 Schlage deadbolts and 2 knob sets that I would like to do this to. What would the zero lift pin depth/size be? Also is the #1 spot the best position? Thanks a lot, I enjoy all your videos. 👍🏻
I would have to double check their chart but it should be easy to figure out with a google search. I am sorry I don't remember off the top of my head
HelpfulLockPicker, no problem, I appreciate you getting back to me. Keep up the great work.
Very cool info, thank you for sharing
《THUMPER》 Lock picking, Police accountability thank you for the kind words :-)
Hi, great video! Where do I get the lock and get it modified?
You can buy online
were do you get the #7 pin? you should sell them or make contact with somebody at e-bay.
charles klein I got them from CLK Supply
ry using a .300 lab pin, It should work.
Thank you but can you update a new way to prevent bump keying. An idiot done showed how to bump key new security locks. Thank you
Thank you for sharing
What is the length (measurement) of the zero lift pin #7? Since kwikset pins increases by increments of .023" and #6 is .287" , would #7 then be .310" for zero lift pin length?
I quickly measured one and it was .307"
Awesome.
Thank you for the kind words!
Will this modification work on the Kwikset Smartkey Locks? Would it interfere with the Smartkey reset capability?
The smart key lock uses a completely different locking mechanism and this would not be applicable to that. I would not expect you would be able to bump open one anyway. That does not make them secure though because you can turn the core open with a key blank rather easily
Great info!!!
Thanks for checking it out!
I didnt know about the 7 cut... this actually will help me with a real life situation
Can this be done to a schlage deadbolt.
If you can get the right sized keypins you could for sure
just add a stronger spring or double up 2 springs on 1 of the chambers. Uneven springs = can't be bumped.
Thanks for sharing
@@HelpfulLockPicker non-uniform springs also defeats tubular lock impressioning.
talk a bit slower, no hurry! im stupid so can you show me how to do it and were to get the parts? you explained why but not how? also if cost were no concern how could i make it imposable to pick or bump a lock
charles klein Check out my video [81] on how to take a lock apart and put it back together th-cam.com/video/Z6nEHMbOoHk/w-d-xo.html
What you are doing is putting a keypin in that is too tall for a bump key which will make it not work. For Kwikset it is the #7 keypin and you can buy it at CLK Supply (online).
Once installed, you would need to make a new key since the key pins have changed. You can bring your original key down to the lock Smith and tell them you out a #7 keypin in whatever slot you put it in.
If you want to take the a step further lock picking lawyer did a video on adding t pins to a Kwikset to make it pick resistant if it has construction keying holes
what you are saying is VERY interesting! "Construction" key holes? are you saying "GRUB" screw in set screws? how do you do that do you drill a hole or do they just screw in are they SELF threading! what is the #7 keypin i thought it only had 6 pins? i have not done your video [81] thank you very much! i have seen lock pick lawyer on the "t" pins replacing.
charles klein You need to buy a tool to add the threading but you take the cap of the lock and screw threading into the top of the bible and screw in grub screws. It makes top fitting easier when you go to reset the lock.
I can show you the specific tools if you'd like.
