While doing some urban exploration in an abandoned hotel, I saw these locks on all of the hotel rooms doors. I am wondering what the pin to the right of the keyway is for. The pin appears to be spring-loaded. The locks ia a sargent.

Just a guess here, but I'm going to say that if you put in a master or control key, and press the pin you can pull the core and take it down to the hotel's keyshop and have the lock rekeyed if a change key was lost by the person staying in the room.

How far is your urban exploration going? Are you actually picking those locks and checking out what is behind them. Man I'm envious-- it would be a lot of fun to have something to explore.

because the lock face is large and the plug is in the center, I am betting that it may be a variation on the corbin ring cylinder (hope i named that right) which is a system that has a master key setup that cannot be "rights amplified" in the way described by matt blaze. There is a second cylinder between the plug and the lockcylinder, and the master key unlocks this one. as for the little pin, that most likely is the lockout to keep the maid from walking in on the guest, its a common old type of hotel lock, and this function can be operated from the inside of the door, but a managers masterkey likely could open it. If you get a copy of one of these locks and dissasemble it, let us know what you find.

A second look at the picture tells me that its just a kik with the privacy lock and not the variation on a corbin ring cylinder, I saw that tulip knob as a cylinder rather than a knob and thats how I made the mistake. This is a common hotel lock, of maybe the 1980z. when the privacy function is applied, the little pin comes out and indicates to the maid that its locked from the inside, it also disengages the ability of the maids key to function, but as I said, the manager has a key that will open it. you can just press some button on the inside and see the pin pop out. I would assume that the system is mentioned in Lss

raimundo is correct, the pin location indicates whether someone is actually in the room or not. On the inside knob the center button is used to push that little pin out. This causes normally cut keys to be unable to operate. Generally the masterkey has an undercut near the tip which can bypass this function to allow entrance.

Thanks. There is a little sign above the lockset (in the room) that says something like: "Do not push in center while leaving room, only push while in room for complete privacy".
Lockedin: There's no need to go around picking locks; the doors, including the rear door are all open. Plus, the keycabinet in the building is wide open. When I came to the vending machines, I had a good laugh. The machine's locks were ripped open, the money was gone, but the machines were still half filled with sealed sodas! I know I shouldn't have, but I drank one.

Shrub, it's funny how the cash registers in the bar and manager's office were still intact.
Yea, the soda was pretty warm but I was sweating something fierce. Next time I'm bringing some ice. You can always skinny dip in the pool, too. (even if there is some mold.)

Now that does supprise me, cash registers etc would be the first to dissapear all together in this country and then find their way on to ebay,
Perhaps theyve been putting rat poison in the cans of soda with syringes
