Double Keyed Cylinders for Multipoint Lock Handlesets

Double Keyed Euro Profile Cylinders for Multipoint Locks

Double keyed cylinders, also known as key/key or full double cylinders, require a key to lock or unlock from both the interior and exterior sides of the door. This configuration is commonly specified for commercial entries, security doors, storm doors, and gates where preventing unauthorized egress is as important as controlling entry. MPLocks carries double keyed cylinders compatible with Euro profile multipoint locks, including options that work with Hoppe HLS9000, Fuhr, GU, Marks, and Atrium hardware systems. Whether you're replacing a worn cylinder or upgrading security on an existing door, finding the correct length and keyway is essential for proper fit and function.

Sizing Your Double Keyed Cylinder

Euro profile cylinders are measured from the center of the cam to each end, typically expressed as two numbers (such as 45.5/31.5mm). The total length must match your door thickness and lock position. Doors between 1-3/4 and 2 inches thick generally use cylinders in the 60mm to 81mm range, but always measure your existing cylinder or the lock case specifications before ordering. An improperly sized cylinder will either protrude unsafely from the door or fail to engage the lock mechanism correctly.

Keyway Compatibility and Rekeying Options

Double keyed cylinders are available with different keyway configurations, including Yale, Kwikset KW1, and Schlage-compatible options. Some cylinders offer the convenience of standard keyways that your local locksmith can duplicate or rekey, while others use proprietary pins that cannot be changed after manufacture. If you need multiple cylinders keyed alike for a single property, look for cylinders specifically marked as keyed alike or contact our team to discuss your options.

When to Use Double Keyed vs. Single Cylinder

Double keyed cylinders are appropriate when both sides of the door require keyed security, such as gates, security screen doors, or commercial entries with glass panels near the lock. However, many building codes restrict their use on primary egress doors due to emergency exit concerns. Before installing a double keyed cylinder on any door, verify that your local codes permit this configuration, especially for residential applications. Single cylinder options with thumb turns are available for doors requiring quick interior egress.
