Thumbturn Door Lock Cylinders, Keyed-Alike Options

Plan a matching cylinder replacement with a thumbturn-style door lock cylinder. Different size and package options let you choose the arrangement for compatible lock bodies.

• ✅ Use a thumbturn on the pictured side - the knob provides a mechanical operating point.
• ✅ Choose the matching size - compare the cylinder and tail dimensions before purchase.
• ✅ Plan matched-key access - keyed-alike options are described for corresponding supplied cylinders.

One Matched Key Does Not Mean Every Lock

The keyed-alike description refers to matching supplied cylinders, not a key that opens unrelated locks. Confirm the selected pack count, cylinder length and keying arrangement before ordering multiple units.

Compare the lock-body connection, cam, door thickness and required inside/outside orientation. No tested burglary-resistance grade is supplied. The cylinder does not include a complete smart lock or door assembly.
