Medeco reassembly

I seem to have done a very stupid thing :oops:

I am putting a Medeco cylinder into a Schlage deadbolt, and they are definitely compatible. However, I at one point forgot that I did not have the rear cap on the Medeco lock and pulled the key out. All of the pins (top/bottom) and springs flew out. The sidebar also came out.

I cannot seem to figure out how the sidebar fits back in. When I reassemble the lock and put the key in, the sidebar doesn't disengage and so I can't turn it. There are some times when the key will not even come out!

As far as I know, the lock is a Medeco #20-0901. It is not the newest, and it's definitely not a G3. The keys have a round top.

Any help would be appreciated, and I can provide pictures if they are needed. Thanks!

Okay, I've played around with it a bit more and can hopefully provide more information.

The lock works fine - my problem is that the sidebar is engaging when it should not be. If I have the lock fully assembled and I insert the key, it will turn fine. However, the sidebar will engage and I am unable to remove the key until I turn the entire lock mechanism to the right so that the sidebar physically falls out of place.

I don't think that the sidebar is supposed to work like that, correct? How can I keep the sidebar from deploying when it shouldn't?

Alright, here are some pictures:

Um... *confused*

How does a Medeco plug fit in a Schlage shell? What kind of Schlage? Does it have accommodations for the sidebar?

I'm afraid I don't get it.

Your problem is that you don't have any springs for the sidebar. The sidebar should have 2 springs on each end pushing it outwards. At least I think that is the problem. It seems to correspond with the key not coming out.

I think he means into a schlage deadbolt assembly. He still has a Medeco shell on it, it's just that some Medeco shells fit into different deadbolt assemblies.

DB: The lock is a Schlage B160 deadbolt. This is where I got it from. It's compatible with the lock; before I disassembled the cylinder itself it worked :oops:

n2oah: Hm, I don't think it ever had any springs. I'll take a look around.

Yes, that's it. I'm sorry, I'm not entirely familiar with the terminology.

Yup, then it's definetly the springs. The springs should push the sidebar out towards the shell when not in use. When in use, the springs compress by the torque exerted on the key, and the sidebar can retract. Ya got me?

Yeah, I get that. I just don't see any springs, and I can't see where they might have gone on the lock.

The springs go in those two tiny holes before the final sidebar fingers on each side.

Noah is right. You are missing the 2 small sidebar springs. Search your floor for them.

by g5 » 28 Oct 2006 0:18

Oh, tiny springs, my favorite :lol:

Well, time to start searching! Thanks for your help, I really appreciate it!

These springs are tiny and they are easily lost, but they hard to find substitutes for.
