Sargent 05-0040 – Frequently Asked Questions

1) Will the Sargent 05-0040 tailpiece work with my 6500 Series mortise cylinder?
The 05-0040 tailpiece is made for Sargent 6500 Series mortise cylinders built with the 7-Pin XC keyway. If your cylinder is a 6500 mortise in that 7-Pin XC configuration, it drops in with no modification. A 6500 cylinder in a different keyway or pin count is not what this part is matched to, so confirm the keyway stamped on your cylinder before ordering.
2) Can I replace just the tailpiece instead of buying a whole new Sargent mortise cylinder?
That is exactly what the 05-0040 is for. When the original tailpiece is worn or damaged and the cylinder itself is still good, swapping the tailpiece restores the cylinder-to-lockbody drive without replacing the full cylinder assembly. Your existing keying stays as is, since the cylinder and pinning are untouched.
3) Is the Sargent 05-0040 a genuine Sargent part or an aftermarket copy?
It is a genuine Sargent OEM component, catalogued under Sargent Lock Parts and built to original factory tolerances. For institutions standardized on Sargent hardware, that matters: an OEM tailpiece keeps the cylinder engagement within factory spec rather than relying on a generic blade that may sit long or short in the lock body.
4) What does a cylinder tailpiece actually do on a mortise lock?
The tailpiece is the flat drive blade on the back of the mortise cylinder that transfers key rotation into the lock body to retract the latch or throw the deadbolt. If it is worn, bent, or the wrong length, the key turns but the lock does nothing. The Sargent 05-0040 is that drive part for 6500 Series 7-Pin XC cylinders.
5) Do I need to rekey anything after installing a new Sargent tailpiece?
No. The 05-0040 is a mechanical drive part on the rear of the cylinder and has nothing to do with the pinning or the keyway cuts. Your existing keys and any masterkey system stay exactly as they were. It is matched to the 7-Pin XC keyway only in the sense that it is the correct part for those 6500 Series cylinder bodies.
6) Is the Sargent 05-0040 tailpiece suitable for high-traffic commercial openings?
It is a commercial-grade part, not a residential one. Sargent lists it for commercial office buildings, schools, healthcare, government and municipal facilities, retail, industrial and warehouse sites, and multi-tenant residential or mixed-use buildings. For a property manager carrying spares across a building, it is the part to stock when the doors run Sargent 6500 mortise cylinders in XC.
