Bumping on locks with pins up?

[cipher]

Does bumping work on locks that have the pins on the bottom (the key edge facing down instead of up)? I have one of these locks in my house, but bumping doesn't seem to work on it (I've tried a hammer etc).

Also, I didn't shave any off the tip or sholder of the key because I read that you don't need to. Could that be the problem?

Thanks for your replies.

I should work no matter which way the lock is turned.
If you haven't cut the shoulder and tip, then you need to use the pull back method. Insert the key, then pull it back 1 notch, then bump while appling very very light tension on the key.

Dont us a hammer to bump, I've done the experimentation, and the plastic bump hammers or the right plastic screwdriver handle are what you want, reduce the force and just make it a quick hit, not a hard one.then if you are turning at the right time, its open

Also it could be all in your mind that your not doing something right. After a couple unsuccessful bumps you might think "Maybe upside down locks cant be bumped" without really giving it the effort. I could see myself thinking the same thing. Its not any different than a lock that has pins going upward, on a difficulty scale. But you might tell yourself it is. Actually it might be easier but that is just speculation.

It all depends on how you hold to key in contrast to the new situation.

In regards to the shoulder.
Look up the difference between the pullback method and the minimal movement method.
Basically, one method require you to shave the shoulder and is a bit more reliable.
The other doesnt and can have problems with keys cut to 9th depth.

As to everything else, what everyone else said

ok fist off STOP BUMPING YOUR HOUSE DOOR!

Ive had shoulders break on me and actually damage the lock! that was when i was first playing with bumping and hitting 2 hard. i use the minimal movement method.

And yes it will work on upside down locks otherwise everyone would just turn there locks upside down to prevent it.

Thinks to do -

- Half mill of the shoulder
- A single Wipe over each valley if its a true 999 key, it takes them down a bit in case u have a 9 pin.
- Dont hit to hard
- And in the immortal words of Barry. believe it will work and it probably will
- Do a search there are LOADS of threads that go in to more detail about techniques of how to bump



All the best John

'''Believe it will work''' thats a good one, I like it. we could do a survey/poll of the experienced pickers to see if they also experience the power of belief. of course the limitations are there too, nubes who have a preconception about things, often a wrong conception. etc.

Yeah i've found that if i relax and im confident than any lock i try will open but if im not relaxed or focused i can't do it.

That's just how i am and im sure that alot of others are the same way

It takes just a bit of messing around with to get the right pressure with the bumping plastic hammer. Once you get it, it becomes relativly easy. Nick is right though you have to be relaxed and focused or you'll have difficult. The plastic hammer really improves your success rate. I recommend the MII Bump Hammer

Its more that u will hit it with a sharp precise hit rather than a half assed attempt
