How to Install, Convert, and Rekey a HOPPE Key Cylinder
This guide explains how to install, convert, remove, and rekey HOPPE key cylinders. The steps below are written to help you correctly orient the cylinder, install it in a mortise lock, and understand the requirements for rekeying.
Key Takeaways
- Have tools ready: key, included Allen wrench, and included ring wrench.
- Work with the door open: helps prevent accidental lockout during testing.
- 90° vs 360°: many HOPPE cylinders are supplied as 90° turn and can be converted before installation.
- Drive tab alignment: align the drive tab with the cylinder body before inserting it into the lock.
- Confirm sizing: verify the cylinder size and configuration before installation or ordering replacements.
- Removal tip: remove from the exterior side and pull from the keyed side, ideally with the key inserted.
- Rekeying: confirm the correct key blank type and proper pin sizing before rekeying.
HOPPE Key Cylinder Installation, Conversion, and Rekeying
Before You Start
Have your key, the Allen wrench provided, and the included ring wrench ready.
Whenever possible, work with the door open to prevent accidental lockout while testing or adjusting the cylinder.
If you need to confirm sizing or configuration, you can view examples of a HOPPE half euro key cylinder or a HOPPE 90 degree keyed profile cylinder, or browse additional HOPPE key cylinder options.
HOPPE key cylinders are commonly supplied as 90° turn cylinders. These cylinders can be converted to operate as 360° turn cylinders by adjusting the internal drive position before installation.
Converting the cylinder changes how far the key can rotate once installed.
HOPPE 90° Turn Key Cylinder Installation Steps
Step 1: Loosen the Knob Set Screw
Using the Allen wrench provided, loosen the set screw located on the knob.
Step 2: Remove the Knob
Once the set screw is loose, slide the knob off the cylinder body.
Step 3: Insert the Key
Insert the key fully into the cylinder before adjusting the drive position.
Step 4: Set the Drive Tab Orientation
Using the included ring wrench, press the internal pin downward.
While holding the pin, rotate the cylinder shaft until the drive tab is aligned with the cylinder body for insertion into the lock.
Step 5: Insert the Cylinder into the Door
Keeping the key in position, insert the cylinder body into the door from the exterior side.
Step 6: Engage the Lock
Turn the key to engage the lock and confirm that the cylinder is aligned correctly.
Step 7: Reinstall the Knob
Position the knob on the cylinder shaft and tighten the set screw.
Step 8: Secure the Cylinder
Install and tighten the cylinder mounting screw to complete installation.
How to Remove a HOPPE Key Cylinder
To remove a HOPPE key cylinder, begin by loosening and removing the cylinder mounting screw. Repeat the same steps used to remove the knob and set the drive position.
The key cylinder must be removed from the exterior side of the door. Always pull the cylinder out by the keyed side, not from the knob side. For best control, keep the key inserted while removing the cylinder.

HOPPE Key Cylinder FAQs
Can a HOPPE 90° key cylinder be converted to 360°?
Yes. Many HOPPE key cylinders are supplied as 90° turn and can be converted by adjusting the internal drive position before installation.
Which side of the door is the cylinder removed from?
HOPPE key cylinders are removed from the exterior side of the door.
Can CES pins be used in Schlage “C” keyway cylinders?
Yes. CES and Schlage bottom pins are compatible, but pin lengths vary, so a conversion chart should be used.
For related door hardware, browse HOPPE multipoint lock hardware or view HOPPE key-operated multipoint locks that are compatible with these cylinders.
CES Pins vs. Schlage Pins for HOPPE Cylinders
When rekeying Schlage “C” keyway cylinders, either Schlage bottom (core) pins or CES bottom (core) pins may be used.
Although both pin types are compatible, pin lengths vary slightly between manufacturers. When substituting CES pins for Schlage pins, or vice versa, a conversion chart should be used to ensure proper pin sizing and correct cylinder operation.
