Never seen a storeroom weiser before until yesterday. I re-keyed it and 2 other doors and I thought it was going to be a walk in the park, but it turned out to be a almost a 20 min learning curve for me. A normal weiser will release the cylinder at about 10 o'clock but when you go to stick the key in the door instead of turning the key a quarter turn clockwise to unlock the key actually turns all the way up to 10 oclock and then retracts the dead latch. The back of the lock had a solid square bar that pulls the tail out of the back of the cylinder like a normal weiser but for some reason it would turn only to 10 o'clock and not release. Messing with this lock for almost 10 mins I stopped and re-keyed all the other locks I had which were normal locks and then I was done and picked up the storeroom and messed with it again. About 10 mins later I got FED up with this thing I was about to replace this storeroom with a regular keyed entry and I pulled the square bar out as hard as I could and turned the key and there it was. It released at the 2 o'clock position. Sense the square bar in the back was solid you cant just clamp a vise grip on it and turn the cylinder so you have to pull really hard to get the storeroom to release. I hope this saves someone time if they ever run into a storeroom weiser.

You do know that all Weiser locks don't come apart like this, right? If there is a small "Waldes" ring retainer on the square post in the back, the lock must be disassembled. Start with that ring, remove what you can, there will be a larger ring, remove it. Now you can remove the post and look into the hole. There you will see a retaining cap, much like a Schlage cylinder. Remove that cap CAREFULLY. There is a small bar lying across the back of the keyway, pull it out. There is also a small spring and pin, ala Schlage, watch out for those. Now you can use a follwer to remove the plug from the knob and change the combination. Now, reverse what you have done, and you ARE done!
The small bar across the back of the keyway is for pick resistance. When you pick these locks you need to pick it, turn the plug back to a couple of degrees from locked, depress that bar while turning the plug to unlock. Unless of course you come up with something to hold in the bar while you pick. With the tolerences that these locks have, even if you lock it up a couple of times while trying to "work" the bar, you still won't take long!

The lock i worked on came off just like any other weiser except the only thing was the bottom of the key hole had to be pointed at the 2 oclock rather than the 10 oclock position. I didn't have to take any rings or big clips out to re-key it. The only ring i took out was the snap ring holding the plug in the cylinder. There was a ring on the square post but i left all this alone and just pulled on the square post until the plug was free to turn 360 degrees and it came off at 2 oclock.
