Greetings from your friendly neighborhood locksmith.
I have 18 sets of bump keys for sale. Price is $25 which includes shipping.
The keys are:
Schlage 5 pin
Schlage 6 pin
Kwikset 5 pin
Master Lock 4 pin
American Lock 5 pin.
This is a basic set that covers the most common locks in the US.
So what are bump keys? they're standard keys that have been cut to the lowest depth setting and are used to quickly open locks by inserting the key, backing it out one space and striking it with a screwdriver handle or bump hammer. This imparts kinetic energy through the key and the bottom pins to the top pins, sending them past the shear line and opening the lock. The physics involved are a little more complicated than that but that's the short of it. A rubber washer can be added to the key to allow for more rapid bumping.
Note: Buyer is responsible for ensuring it's legal to purchase/own bump keys in their area. Paypal is prefered payment method.
Sent you an email, shut up and take my money.
Good stuff, and yes, this is the email for payment.
Picked up a set last time, I can vouch for the quality of these keys.
How much extra to ship to Syrupland?
No idea, where at in Canada?
Looks like it's gonna be about the same.

Sorry for the delay in shipping, I didn't get an email notification saying you'd paid so I didn't notice for a couple days. I'm going to expand my key selection sometime after the holidays. I give you 25% off on those if you want.
Your order is in the mail too, email me for the tracking number, for some reason there's no option to send it to you through Paypal.
Are these able to work in smaller locks such as the backup key lock on many smaller gun safes?
It's a weekly occurrence that people bring me these things. The battery died while they where up north and now that they're coming back down for the winter they can't get in because they lost the keys.
I can get in them, but It involves destroying the lock and rendering the safe useless.
The ones I'm selling won't fit, but you can probably find some that do. Cam locks like the one in your post tend to be just cheap wafer locks though so they're retard-easy to pick. I recommend a half-round pick. If you do destroy the lock you can just get a new one at Lowes, Home Depot or the like for between $5 and $10. Though you may have to do some fitting since though cheap safe tend not to be built to any particular standard.
Ben W. here:
I got the package today, can confirm these are bump keys.
Thank you friend
Same for me, pkg got here yesterday.
Now, I've used home made bump keys before but I haven't had any success with these. Does anyone have videos that could help me figure out what I'm doing wrong?
I don't know man I cannot figure this shit out either.
You've had luck in the past with it?
Totally did in the past, maybe I've lost my nack.
Here you go:
Thanks! I want to put a disclaimer here for potential buyers: there is nothing wrong with these keys. This set looks exactly like the ones I used to have. The problem is 100% just me being a retard.
Also if you're trying to tackle a padlock they tend to be more difficult, since you're typically working against the spring pressure and/or security pins. I recommend a Kwikset cylinder like in my video in the OP. If you don't have one in your junk drawer already you might find one at the thrift store or in the junk drawers of friends or family. Make sure it's not a Kwikset Smartkey though, I don't believe those can be bumped. Smartkey locks have a small notch to the side of the keyway to insert the changekey. See pic.
Finally, I still have 15 keysets remaining.
It takes me longer to bump key a door than it does to bump key padlocks.
I think it's just because I practiced almost exclusively on padlocks, so the motion might be more familiar.
These still up for grab?
Where are you shipping from?
Can these be made cheaply too?
If you are serious about picking, just get a Pick gun instead.
They're a little bit more money, keyway specific, easier to use more rapidly, and you can adjust tension of the strike.
You are also going to have a hard time picking any American Pad lock with a bump key, because the you have to over come the tension of the spring on the core. Not saying it's not possible, saying it's very difficult. Locks with free floating cores, deadbolts and residential knobs/levers and Commercial locks that are classroom function are your main target
It's just a trap key. You could get a blank from the hardware store. If a normal key looks like the top picture, you would cut a blank to look like the bottom.
The slopes on either side of a cut/flat spot allow the key to slide in and out as the pins ride along the key.
The bottom just allows the key to slide in, not out. Once you shove it in the lock, if you want something permanent you just break the head of the key with a pair of pliers
Though How I would do it is cut a key blank to 9000 or something similar and then precut the blade with a jeweler's saw to make it easier to break off. You can also slather the ward cuts on the blade with super glue to make it more difficult to remove.
If you're asking me if I could make some I surely could. They're simpler than bump keys. Thing is though their usual purpose is to deny access to a structure, say for instance if you've taken up residence in a old industrial building and you want to limit the number of entrances. For that you would need anywhere from a couple to potentially dozens and they would need to be specific to the keyway. If you knew what you needed and how many that would be fine, but making a bulk supply for a what-if scenario would be excessive.
The cheapest, simplest option would be to fill the keyway with expanding foam.
A trap key is ideal over the expanding foam, as you can still salvage the lock after. You are able to take an extractor to lift up the trapped pin and pull out the key, and thus preventing Extra money from being sent for buying new locks etc.
Expanding by foam is definitely more secure, and a much more permanent solution.
This is true too, I was thinking about it from a more military or police POV where they wouldn't worry about changing locks afterward.
Personally I think disabling locks for security is stupid. You should only do it as a form of insecurity.(Keeping a common area open) Unless a door has a metal frame, or 3 locks across the door, it's going to be kicked in/battered down easily.
Locks are to keep honest people out, and should be treated as such.
