What is this lock?

by **m3ph15t0** » 20 Jan 2007 15:21

What is this, and why are the keys shaped so weird? I see these around my school all the time and was wondering whats with them. Plus, the keys are kind of saw toothed on the bottom. [/img]

wow I screwed that image up royally, could someone fix it please?
And I think that the lock might be sfic or somthing. Unfortunatly I only have the vaguest idea of what that means, and I was wondering if someone could explain what goes on inside of a sfic lock, even if this isn't what that is.

can't really tell you the keyway exactly, but either it's just a regular corbin russwin SFIC (small format interchangeable core) cylinder. SFIC means a special key can be used to remove the entire "8" shaped core to switch it instead of rekeying on the spot. if the key has a weird bump on the bottom where it's normally flat than it's "pyramid" which is a key controlled high security lock.

I have never seen a key with bumps on the bottom. any one have a picture of one?

by **m3ph15t0** » 21 Jan 2007 1:32

Thats not the real keyway, and the key doesn't have a bump, it has a kind of sawtooth pattern with squared off teeth on the bottom. Thanks for the fix shrub.

That sounds like an Emhart key, with the cuts on the bottom. The cuts are necessary for the interlocking pins to pass through the key bottom when the key is rotated past the 180 degree point.

by **m3ph15t0** » 21 Jan 2007 2:42

Wait, what?
interlocking pins?
I've seen my teachers twist the key way past 180 before, but I have no idea what youre talking about. Could you elaborate a little on those pins please?

Yes, the only lock I know that has "saw teeth" on the bottom of the key is the Corbin Emhart. Here's a little article I wrote on how Corbin Emhart's system works.

Holy crap, my school is that secure? It's a government building, I would just expect ten dollar kwiksets!

Ah, so it is a corbin emhart?

Yes, they are very good locks.

at our institutions we have a schlage key that has grooves in the bottom that we use for restroom locks. when locked fro mthe inside a normal key will not operate the lock but these with the grooves will. i will take a picture and post it up, also it could be a full size ic similar to the schlage design, heck the pcsb purchased a keyway from schlage to help secure our institutions,

Yeah, not all of the keys in our school have the grooves, only the ones for certain doors, like the major ones into the different areas of the school. Also only those people who are high muckety mucks get to have the grooved keys. Could they be master keys by department or somthing?

Schools invest a good bit into security. At my school all the doors have keys with 5-6 dimples on the the side plus a fair number of pins.
