New to locksmithing. What kind of lock is this?

[MrWizard]

Here is an example everyone can identify with.

Key blank catalog:



Now look at the end of your Kwikset.



It looks like a mirror image because you have to place the tip of the key on the profile image like it is going into the lock and look down both sides one at a time to match a keyway. Or look at the profile picture in the book and look at the actual lock which is much less accurate but will get you close.

Yep, you guys are right...I had it backwards. Its definitely an H series.

Oh yeah, and just a friendly tip...When you take the door handles off and the screws that hold the lockset in place, make sure you have a finger inside the lock hole in the door & through the lock hole on the lockset. You dont want that falling inside the door, thats a whole other nightmare. Im not exactly sure if that door is hollow like most storefronts but I'd bet that it is.

The door won't be hollow. Steel doors prepped for a mortise lock have a mortise pocket. You would have to work very hard to drop that down a door.

The lock comes apart by rotating the collar around the inside knob in reverse while pulling on the knob. Not the parts that come off because it can get confusing as to how they go back on the spindle.

The cam should be the Corbin/Russwin cloverleaf cam A01. These locks rarely break so make sure you really need to replace it. You will need to purchase a complete lock not just a mortise body as the old style is not compatible with the new style. So you will need the knobs/levers, the escutcheon, the armored front, the lock body and the mortise cylinder.

You also need to confirm the function. Some of this depends on usage and also on code. Best bet is to check a similar door. I would assume you need a ANSI F11 or F04 function.
