issues with keying a lever lock

[Punkty24]

I have recently disassembled a lever lock I have, and am struggling with making a key for it- see below I have traced the gate positions of the levers, and then shown their relationship tp each other...Can anyone give some guidance as tp the rough shape I'm lookin for plz??

Fastest way would be to impression the lock.

The next way, which would be easier since you have the lock already disassembled, would be to install one lever, and keep trying/cutting that particular bitting on the key until it works. Then add the second lever, and repeat until you have all the levers installed and the key works. At least that would be my method.

Im with GWiens2001. It looks like the levers on a chubb 110. Start with the back lever, and file till you hit gate. then lever 2 and repeat.
Going by your lever tracings its going to look roughly (5 to 1) High,Mid, High,Lowest, Lowish.

I dont think you can impression a Chubb 3g110.

This is a quick snapshot of the inner mechanism, levers intact.... Does this either confirm or refute your theory of the locks obesity issue (Chubb-yness, berdum-CH!) I may have been awake slightly too long right now lol apologies...

Could you possibly scribble a rough sketch of your suggestion of rough silhouette profile shape I should be aiming for with this pleae, I am struggling to get my brain to fold the one image into the 3d projection to the key.

Thank you for helping me with this btw guys I do appreciateit

Yep Im still of the opinion. Start at the back, work your way forward. its on your to do, work list when you wake up.

I'm still unclear as to "high','medium', etc...

Could you possibly scribble a two second guideline idea of the possible shape I'm looking for plz??

You can get the most accuracy not by relying on a drawing, but by doing what we suggested. Put the blank in the lock with one lever, and test/cut/test/cut until that lever works. Add a lever and repeat.

As for high and low, the flag on the key of a lever lock typically faces down. So a 'high' cut has been cut closer to the shaft of the key, and a low cut will have much less cut away for the bitting.

The type-drawing will no doubt have ratlock laughing his head off, but it should give you a rough idea. Very rough! Do NOT try to cut the key like this and then see if it fits.

The "B" is for the bolt, and is what actually moves the locking bolt. Then there are the five levers. Am assuming that this lock is driven by the tip of the key, which not all lever locks do. Ratlock is far more knowledgeable about lever locks than myself. So once he is done laughing, he will probably correct my post.

Good drawing. I got kicked out of art at school so much better than I could do.

nice ascii, but for a 5 lever door lock there would normally a point of reflection and 7 cuts on the key so it could work from either side of the door.

however this is a chubb 3g110, with 5 detainers, so there will be 9 cuts on the key, this is also the lock which is used for the hand cutting a key test for entry to the master locksmiths association in the uk.

if the op doesn't have the correct blanks and good files and plenty of experience, they're not going to do it. and since they don't understand the relationship between the levers and the key, i'm guessing that they don't.

also there are 2 versions of the levers for this lock, the old style and the new. it's impossible to tell which from the op's photo. a better photo with the levers all separated out on some dark paper may help.
