The lock you are describing is from a new style schlage "F" series knob or lever
lockset & that spring loaded cap is very delicate. I don't mess with them unless
it is to rip it off & put on a new cap, which are sold by the 100 at my distributor.
Best to remove the "C" clip at the end of the cylinder & use a tweezers & a follower
(an AA battery or .495 diameter tube) to examine the top pins from the inside out

Then tap the blade from the front face and it will bite into the cap sliding the cap off with no damage.

To reinstall you bend the cap into an upside-down v shape along its long axis and place on top of the bible. Then using the side of a suitable flat piece of metal (I use the side of a bastard file) tap it down. As the v is flattened the cap will slide right under the existing crimps and no other work to secure it will be needed.

Sounds more complex than it is. I've done it this way for at least 20 years and it is really fast. I mainly use it on things like IC core Corbin/Russwin cylinders that are not keyed with a follower.


How, how did I not think of this???? Yes, I did it the hard way after I used the old hacksaw blade to remove the cap, I recrimped it with a blunt chisel.

Excellent excellent tip!!!! I am trying this the next time I can!!

For the best book out there on high security locks and their operation, take a look at amazon.com for High-Security Mechanical Locks An Encyclopedic Reference. Written by our very own site member Greyman! A true 5 Star read!!

I too will be glad to try this out, I usually wind up just rolling the cap off & then hafta pound it flat, then bend it lengthwise into a "V" shape to pound it back into place when I'm done with the lock servicing & that is a pain
