Key Extractor Training Accident "KETA"

by **Wrenchman** » 12 Mar 2006 20:53

Hi , I am trying to learn how to take out a broken key from a cylinder, and I already had a broken key piece, and I made the key extractor from a piece of (soft round)steal, which when you hit it a hammer, gets more hard, and I sort of bite it with a wire cutter, it gives it teeth.

I also had success the first about 5 times, then the key extractor broke inside the cylinder together with the broken key!

By the way it is a padlock, Papaiz CR 40, for sale. US$ 7,-, or 15,- R$ Reais in Brazil

Now it is really really difficult, can anyone help, before I panic?

Regards, Wrenchman

If a normal decent extractor wont work then you can try things like a fishing hook bent out or such like if nothing will budge it you may have to drill out the bottom of the key and then insert somthing to pull the bits out.

You may find when you drill with your 1mm drill that its gets stuck, this is great, pull the drill out rather than un-wind it and you may get the bits to come out.

Hammering things into a keyway is not the way to extract things and i think its lesson learnt, howe about a pic to show others that may be thinking of doing such things in furture.

drilling the bottom and getting a bit stuck is not likely going to reward you with being stuck on the key material and not the brass plug as well.

You may find tugging will get you a broken bit to deal with as well.

Drill 1/16" into the bottom of the key, 1/4" depth, being sure NOT to drill the brass plug keyway. It makes burrs and makes an easy job harder.

MAKE an extraction tool from spring steel (using a dremel with FIBERGLASS cut-off wheels) to fit into and hook into that 1/16" hole.

Works 100% on medeco, the hardest pin tumbler lock I have to extract keys from.

Your wrong it does work and if it doesnt you have the bonus of now having a large area to insert a proper extractor.

Medeco are quite big keyways with quite a bit of space around the key compared to the smaller locks out there.

Drilling a hole in the bottom and levering out has the possability of just levering up the key part into the pins more making it harder to pull out.

I wont condem you idea as i havent tried it, the same reasons you shouldnt comment on my suggested method as youve obviously not tryed it.

Bottom half of key missing = a much easier extraction when somthing has been hammered in to the keyway alongside the key other than that i would use extractors and not even consider putting a drill anywhere near the lock.

You're right.
I shouldn't've discounted what you've discovered and works for you.
We are in different markets and likely you see more N/A cylinders than I see of UK.

"Medeco are quite big keyways with quite a bit of space around the key compared to the smaller locks out there."

I disagree.

We may have to continue to disagree on this point.
I can live with that.

Well i dont know where you are in the world but compared to a lot of euopean locks medecos are fatter keyways.

by **S&G** » 13 Mar 2006 19:51

I don't know that naming keyways will help much,
But the bi-axal is narrower than the non-biaxal.
Medeco's Patriot keyway is fairly fat, C,E,G,M,R,S,X,Y,Z are narrow but W is kinda fat like the sky03.
Regular medeco 00 is very fat, 04,08,20 aren't so bad.

But ASSA's got a big /\ss keyway.
Of course abloy, but that's different.

What do you see for high security cylinders?
Any zeiss?

LOL, No fights on my topic!

It looks like Shrub is insinuating that I am hammering something into the Freeway.

What I said was and I

I made the key extractor from a piece of (soft round)steal, which when you hit it with a hammer, gets more hard and flat, and I sort of bite it with a wire cutter, it gives it teeth

This is in the process of making the key extractor, before the tool gets stuck in the lock

Here are some pictures:

A padlock from Papaiz and a Wire cutter from Mayle

A Padlock without a broken key and a padlock with a broken key!(it is the same lock)

Close-up of the special tool developed to take out the broken key extractor piece

Close-up of the new key extractor, that took out the broken key, after the old key extractor piece went out!

Extreme close-up of the broken key extractor piece X 2, it is about 5mm in length!

The broken key which came out, in fact the same day, notice that it has a burr in the end of it, could be due to the fact, that, I did hammer on the broken key while it was in the lock, hoping that I could get the broken key further into the lock :roll:

and that the broken key extractor piece would stay in the front, and thereby fall out, but no! :shock:

Like I said, the key extractor broke in side the lock together with the broken key, because it got stuck, and I took a plier and pulled real hard, thinking that I could take out the key by force,

, well the key extractor obviously had a weak point!

The "broken key extractor piece remover" is less than half a mm in width, and was put in between the broken key and the keyway in the top right corner just below the first pin, where the broken key extractor piece was seen stick out!

After the broken key came out, I tryed a ny technic, the welding technic, goes like this, you take two pieces of electric wire add 110-220v and make a short circuit on the key, which was surposed to make the el-wire get stuck on the key, it didÂ´nt work, maybe less volts, and a fuse to break first :?:

Have not tryed the superglue technic yet, :idea:

LOL, Wrenchman

Ok fair enough i did get the wrong end of the stick slightly but the methods remain the same for removing it, dont use the glue method as its not a mettod and will probably end in tears,

You may have already damaged the lock as in the springs with the heat youve put in it already.

s&g, i was meaning the bi-axial, ive got one of our normal yale cylinders in front of me next to the medeco and if i take the ey from the yale and cut some off the top (the yales are a bit taller keyway) then put it into the medeco it would rattle around. I would not call any of the medecos ive seen a small or tight keyway, the us locks are renown for being larger keyways.

Many American keyways I've seen are looser than Linda Lovelace was.

I triped and fell down an American keyway the other day :lol:

by **Shrub** » 13 Mar 2006 22:03

In the style of the predator film,

Is this an american keyway?

The weird thing was i found a Yale key at the bottom :lol:

by **Shrub** » 13 Mar 2006 22:23

The really weird thing is that the key was in the yale cylinder as well :lol:
