Disassembly information for old Wilka cylindrical lock

Submitted by Hexabor t3_125xsf3 in DIY

Hi!

I have an old Wilka lock on a door and I want to disassemble it.

The question is that I can't figure out how to do it. I see that the lock has on the inside a kind of notch that may have to be used to disassemble it. But no screws or anything else...

For more tests that I have done I have not been able to find the solution to disassemble it. I don't know what else to try...

Anyone knows how to do it?

These are some pictures of the lock (from the inside, the outside doesn't have any notch or screw. Just the cilinder):

Thank you very much!

Cheers.

EDIT: Finally I wrote Wilka (the lock Trademark) and they send me the original instructions (in spanish and german. Here it is, just in case is useful for someone.

Thank you all!!

Remove the faceplate on the edge of the door (at the bolt). On one or both sides of the bolt, look for a small hole. If present, there may be setscrews in those holes that I believe engage the slot you mentioned. If so, back out the setscrew(s) and then the cylinder should unscrew from the internal lock body. Good luck!

Hi!

Thanks for the answer. I appreciate it.

I'm afraid there are only two screws in the faceplate but it seems they are to set the lock agains the door only. Anyway I removed them:

I cleaned the lock with a driller but I dont see any other holes on it.

This is very strange.

Many thanks any way!

Remove that plate and underneath it you will find the set screw

As kitwashere suggested, did you remove the edge plate and look for 1 or 2 small holes just to one side or both sides of the bolt (the holes would be covered by that plate)? The hole(s), if there, would be very small and hard to notice unless you knew to look for anything there. I think a small hex driver (perhaps ~.063", .078", 2mm...) is typically used to back out the setscrew(s).

Many thanks!

Ah, so that probably explains what those scratches along the groove were about. They match perfectly with the use of a wire tool.

Glad it worked out. Thanks for the update!
