Replacement Cylinder for Compatible Smart Door Locks

Replace the mechanical cylinder in a compatible smart-door-lock assembly with the matching pictured version. Separate fully automatic and semi-automatic options help you choose the connection required by the existing lock.

• ✅ Replace the cylinder separately - keep compatible parts of the existing lock assembly.
• ✅ Choose the operating format - fully automatic and semi-automatic options are listed.
• ✅ Compare the tailpiece - the pictured connection helps identify the required part.

Match the Existing Lock Mechanism

The fully automatic description refers to a lock that releases without pushing the handle down; the semi-automatic version uses the handle after unlocking. Select the cylinder for the actual mechanism, not only the door style.

Compare the tailpiece shape and length, cylinder dimensions and fixing arrangement with the original part. This listing does not include a complete fingerprint lock or establish a tested security grade.
