Lock Cylinders, Keys & Parts — OEM Replacement Components

Cylinder Types & Compatibility Across Door Hardware

Lock cylinders are the core security component in any keying system. Specifying the correct cylinder type—American flat-tail, Euro profile (half, full, or double-key), mortise, rim, or knob/lever—is critical to installation success. Mismatched profiles or pin configurations create callbacks. Stock the right variants for your service vehicle or job site.

Match Your Hardware Profile & Keying Needs

Identify your existing hardware first: measure cylinder length (mm or inches), count the pins, and verify bore profile. Euro cylinders dominate multipoint locks; American cylinders fit traditional mortise hardware. Rim and knob/lever styles serve specific door types. Papaiz oval cylinders address niche European applications. Cross-reference the handle set or multipoint lock spec sheet to confirm cylinder compatibility before ordering.

Sizing & Pin Configuration — Avoid Rework

Common mistakes: ordering a half-cylinder when full is required, or mismatching key blanks to pin counts. Measure exposed cylinder length on the door face. Euro cylinders come in 30/30, 30/40, 40/40 split configurations; mortise cylinders vary by lock type. Keying supplies and blanks must match your pin master or existing key. Verify door thickness accommodates cylinder projection.

Volume Orders & Trade Support

Managing fleet maintenance or servicing multiple properties requires consistent cylinder stock. Order by profile and keying standard (all keyed alike, keyed different, or master keyed). Technical specs include backset, projection, and pin count. Contact support for cross-reference help matching old hardware to current SKUs or for bulk keying coordination.
