I made a bump key out of that key, I do not know if its going to work :cry:

. I need to get the lock to try it on, it may need more filing in some spots.

If you insert that key into the lock you will not be able to withdraw it. You need the areas between the bitting surfaces to be cut on angles to help push the pins up when inserting the key and once again when withdrawing the key. The way it is cut now, as soon as a pin falls into the first cuts on the key it will be traped as there will be no leading angle to force the pins up to insert it further or trailing angle to force the pins up to withdraw the key.

Yes, the good news is that you didn't have a lock to try it in, therefore you've saved yourself the hassle of trying to remove that key from the lock.

The bad news is you'll need another key to make a bump key out of. For an idea of how to file the key, think about how a normal bump key works. It has angles cut that still allow the pins to ride up and down the key as the key is moved in and out of the lock. This key would need to have the same. You could get by using a square file and cutting a "V" into the key to a the deepest possible cut on the key, however you'll likely have to guess a little at what that cut might be, as I don't think you'll have an easy time getting proper cut depths for that key. You could always try filing up to the deepest cut that is currently on the key, then cutting a little bit deeper. Should do the trick, thought it'll have to be on a different key because I'm afraid that one is done for.

Cheers!

I cut a bumpkey once and didn't cut both sides of the peaks at angles...

put the key into the padlock all the way, then tried to pull the key back one space.... and that was it... stuck, wouldn't move - I had to get it out one way and that's what led me to make that guide on modifying a tricircle to be repinnable... I got the key out fine after all the pins had been removed lol.

I'm going to make a sodding bump-key for this lock, it's interested me now

All the keys for the display locks in the showroom have 90 degree cuts on them. Stop people taking the keys out when they're looking at the displays.

Does anyone actually know of a bump key being used on a cruciform lock before?

Obviously bumping these locks will work if done properly, but it would be nice to see it proved by a lockpicking101 member.

Quite exciting: the thrill of the new!

it was my idea :twisted:

I assume these keys operate the locks, too? Very interesting idea on behalf of the managemet.

Bump key... nah, not worth the filing time. These locks rake open real easy with the cruciform pick. usually the third or fourth try.

For those so inclined though... Personally... I think the key pictured above is still salvagable. It just needs little peaks made into it.

Why not just leave the cabinet unlocked then if you can't remove the key?

n2oah: Yes, the keys operate the locks, enabling the customer to see the functions of the lockset, but they cannot remove the key.

Db: There's no cabinets involved. These are deadbolts, knobsets, mortise locks with cylinders, leversets, etc. that have been mounted onto a small wooden stand. The key has 90 degree filed cuts on it and is inserted into the lock and left there. It operates the lock and customers can't remove it.

Ohhhh! I misunderstood completely.

Makes sense now.
