Servicing Everest 29 Cylinders
Servicing the Everest 29 lock cylinder is similar to the conventional Schlage lock cylinders. If the lock cylinder is a key-in-lever or modular rim cylinder, remove the cap, tailpiece, driver and spring. If the Everest lock cylinder is mortise cylinder, remove the cam.
Insert an operating key and rotate the plug approximately 90 degrees. Push the plug out of the shell using a plug follower.
Important: The key keeps the check pin in place when the plug is removed from the housing. If the key is removed, be careful not to lose the check pin and spring.
Carefully remove top pins and springs from the shell, and then remove bottom pins from the plug.
Schlage full sized lock cylinders are designed to use a balanced pin stack. If the total length of the bottom pin and master pin (if used) is 0 to 3, a number #1 top pin (.235”) is installed. If the total length of the bottom pin and master pin is 4 to 6, a number #2 top pin (.200”) is installed. If the total length of the bottom pin and master pin is 7 to 9, a number #3 top pin (.165”) is installed.
Combinate the lock cylinder using new top pins, master pins and bottom pins, and springs.
If no operating key is available, disassembling the lock cylinder is a two-step procedure, as the check pin must be raised in order for the plug to be removed. A special removal key is required to raise the check pin to the shearline if no operating key is available.
To create a removal key, cut an Everest 29 key blank blade to a number nine depth. Make sure the cut portion of the blade is flat, so it can be slid into the keyway once the lock cylinder has been shimmed.
Shim the pin tumblers to clear the shearline. Leave the shim in place and remove the key blank. Insert the removal key. Once the check pin has been raised, rotate the plug 90 degrees and remove using a plug follower.
The Schlage Everest 29 patent protected key system provides key control, limiting the possibility of unauthorized access. Selling Everest 29 locks and keys provides your customers with patent protection. In addition, Everest 29 key system users can also incorporate Primus XP lock cylinders for exterior and other applications where high security lock cylinders are essential.
Ingersoll Rand will continue to support the Everest product.
