WWII Jeep H700 key core removal

[45G503]

Hello

This is a WWII Jeep spare tire lock and key. This key fit the entire Jeep in WWII, ignition, tool box locks, glove box locks, spare tire lock, and 2 padlocks supplied. And EVERY Jeep was keyed the same! As well as other WWII vehicles! The keys are marked H700 and were made by Hurd, Yale, ILCO and others. Briggs and Stratton type #1 keyway if I am correct?

OK enough of the history lesson!

Anyway, my question is, how do I remove the core? I obviously don't need to pick it as I have the key. I just want to be able to pull the core to clean and lube it and peek inside.

I have read about core keys.. Is that what I need? Where do I get one? Or how can I make one?

Thanks

There will be some way its fastened on the back of the plug, it will be screwed on with a square drive, either something screwed into the plug or the plug will have a thread on it and a nut will hold it together, you just undo that and with the key in pull the core out.

Hi
Thanks, but there is no access from the back nor sides. Its solid all the way around.

Without meaning to sound a git, it was put together somehow so it will come apart somehow.

Is there anything at the bottom of the hole on the second pic?

I take it the key turns and the nut spins so the nut is fastened to the back of the plug.

My advice is leave it alone, spray it full of WD40 until it runs clean then let dry, after oporating the lock a few times then spray a silicone lubricant inside until the WD40 is replaced.

Go and buy another $2 wafer lock and play with that instead,

That way your not spoiling somthing that doesnt need to be destryed by playing with it when your not too sure what to do, its only a basic wafer lock and nothing special hence me answering this thread as auto locks are usually kept the to the advanced sections.

Have a look around for wafer locks and cam locks

Hi
Sorry if I posted to the wrong section...

When unlocked, the bolt (correct term or not?) retracts and the whole lock comes off the special nut.

This is a WWII original, I have a newly made , reproduction of this to play with so I don't harm the original.

Why? Just a curious hobbyist thats all

Thanks

No you havent posted it in the wrong section, you cant get into the relevant one and it would normally be locked except vehicle security has somewhat moved on from when your vehicle was made and also you havent asked how to pick it.

I fully understand how the arrangement works in use but not how you would get the plug out henc my suggestions,

On the second to last pic you showed there was a big nut in th hole, i guess this screws on to the other part by rotating the key and basically screwing the arrangement in place by turning the key, this means the nut part is fastened to the back of the plug, there must be a way of getting the nut from the back of the plug and then the plug will come out from the front.

Look down the mddle of the nut part and see if there is a screw or smaller nut, it is that which you need to undo, if not you will have to hole the nut and unscrew it from the mechs if thats how its made, im guessing it may have a thread of its own on the otherside that screws into the plug or a thread on the plug.

Dont force the key you will break it, do this without the key in and turn the nut, but only try that if its not got anything down the hole that can be undone.

It may also be a left hand thread so it doesnt undo whilst undoing the nut from the wheel.

Hi

No the nut is a seperate piece. One screws the nut on to the stud holding the tire to the spare tire bracket. Then tighten it with the lug wrench. Then the lock unit is snapped on top. There is a spring behind the nut helping it to pop off when unlocked. The lock cylinder is next to, parallel to the nut and spring. Not in line with it.

See the 3rd picture with the nut removed. It shows the bolt and the spring.

Thanks again for helping a rookie.

So the nut i can see on this pickture come out easliy and there nothing behind it?

[Shrub]

If im understanding you right then you remove the nut and your left with the last picture you posted? if thats so whats at the bottom of the spring? can you see a nut or someing?

[Shrub]

Right i see now, the back of the lock will have a cam on it that moves the ball out when the key is turned.

Im not 100% how you would remove the lock then.

If its for playing with, they are only very cheap locks and personally i would go and buy a new lock to play with.

They are rubbish for picking as they are so easy so you wont get much fun out of it, they are the same as most fileing cabinet locks.

Hi

Please don't laugh, a quick crude pic to show how it is arragned. Thanks for the help.

Let's try again

[Shrub]

Yes thats what i thought, without actually seeing it, its going to be hard to suggest anything unless someone is familier with that specific arrangement like a ww2 jeep forum, you could start removing the pain and looking for pins etc that are holding it in but as i say, you know how the mecanisim works as youve drawn it, the lock is crap just buy another one without all the nut retaining part etc and pull that apart, you will find one under the heading cam lock or fileing cabinet lock.

What you have works, and is used, dont start messing with it as its not obvious what to do.

I have some suggestions. These are mechanisms that are in current use, but who knows about how these locks were constructed. It may not be possible to dissassemble that lock non-destructively.

1.) There is an extra wafer in the back of the lock. Lifting this wafer with a pick will alow you to slide the plug of the lock out when the lock is picked.

2). The plug is held in place by a retaining pin inserted into the lock body. The cutout in the plug could be a slot that goes say, 90 degrees around the plug. This would also act as a "stop" for rotation.
