Keying
Keying
The following instructions assume that the reader has basic experience pinning conventional cylinders. The difference between
Everest 29 and traditional cylinders is the check pin and spring located in the special chamber on the bottom of the plug. If
using a key to remove the plug, the key will hold both the check pin and check pin spring in place.
Rekeying when you have the old key (no master keying)
1. Remove the cam, tailpiece or other type of
plug retainer.
2. Insert the old key and turn it
slightly in either direction.
3. Push the plug out
gently with a plug
follower (M504-548
for modular
cylinders).
4. While the key is still in
the plug to hold the check pin in place, discard the old
pins.
5. Hold the check pin in the plug with your
finger or thumb. Remove the old key
and insert the new key.
6. The new key holds
check pin in place while
the bottom pins are
installed and the plug
is put back into the
shell.
7. Reinstall the cam, tailpiece, etc.
Master keying
The master keying capacity of full size Everest or Everest 29
cylinders is the same as Schlage Classic cylinders: 4,096
theoretical changes per keyway using two step progression.
The MACS is 7. When master keying Everest or Everest 29
cylinders, Schlage recommends using a setup key to
reinstall the loaded plug.
A setup key can be made by cutting a key blank to a 9 depth
in all positions. When the
steeples between the cuts
are removed, the setup key
can hold the check pin in
place when removing the
plug of a shimmed cylinder.
1. Insert any operating key and
turn it slightly in either direction. Gently
push the plug out with a plug
follower. For the modular
cylinder, we recommend
the M504-548 follower.
2. Keeping the old key in
the plug, discard the
old pins.
3. Hold the check pin in
position with a finger
or thumb. Remove the old key and insert the setup key. If
you are certain that the cylinder was not previously
master keyed, skip to step 5.
4. IMPORTANT: Clear the cylinder shell of any remaining
master pins. If master pins remain in the shell, the
following problems may occur:
• A key cannot be inserted or removed
• One or more springs may get crushed and cause a
future lockout
• Additional keys will operate the cylinder.
Using the M504-548 follower for modular cylinders,
slide the flat section of the follower inside the shell and
rotate the flat section until it comes under the bible. All
the master pins will then fall out. Rotate the flat section
until it is opposite the bible and slide follower until about
an inch is protruding from the front of the shell. Replace
any weak or damaged springs. Load the proper size top
pin based on the plug total (bottom pin + any master
pins). A plug follower with a groove will help guide each
spring and top pin into its chamber as you push the
follower in from the back of the shell. (The 40-116 shell
loading tool can make this process easier.)
5. Install new bottom and master pins into the plug.
6. Orient the plug so it is slightly turned with respect to the
shell. Gently push the plug into the shell, pushing the
plug follower out.
7. Test all keys for smooth operation.
8. Reinstall the cam, tailpiece, etc.
