Alarm Lock HW580 – Frequently Asked Questions

1) What does the Alarm Lock HW580 tailpiece actually do?
The HW580 is the tailpiece that links a Schlage KO keyway cylinder to the lock case mechanism on Alarm Lock commercial mechanical locks. Turn the key, the cylinder turns, and the tailpiece is the flat bar that carries that motion into the lock body to retract the latch. If the key turns freely but nothing moves inside the lock, a worn or broken tailpiece is a common cause.
2) Will the HW580 work with a Schlage KO cylinder I already have in the door?
Yes, that is exactly the cylinder it is cut for. The HW580 is built to interface with Schlage KO keyway cylinders driving an Alarm Lock lock case. If your cylinder is a different manufacturer or a different Schlage cam/tailpiece style, this is not the piece you want.
3) Is the Alarm Lock HW580 a genuine OEM part or an aftermarket copy?
It is genuine Alarm Lock, supplied by the manufacturer as a replacement part for their commercial mechanical lock cases. For a facilities or MRO buyer standardizing on Alarm Lock hardware, that matters: the tailpiece geometry has to match the lock case it drives, and an OEM part removes the fitment guesswork.
4) Do I get a cylinder or a lock case with the Alarm Lock HW580?
No. The HW580 is the tailpiece only, sold as a service part. The Schlage KO cylinder, the key, and the Alarm Lock lock case are all separate. Locksmiths rekeying or swapping a cylinder usually order the tailpiece alongside the cylinder because the old one is often worn or the wrong length for the new setup.
5) When should a property manager replace the tailpiece instead of the whole lock?
If the lock case and cylinder are sound and the failure is in the key-to-latch handoff, the tailpiece is the cheaper fix. Symptoms are a key that turns but does not retract the latch, or sloppy play between cylinder and lock. The HW580 is stocked for exactly that kind of preventive maintenance and service work on existing Alarm Lock installations, so you keep the door hardware you already have instead of repapering the opening.
6) Is the HW580 tailpiece rated for commercial use or is it a residential part?
Commercial. It is specified for commercial-grade mechanical lock applications, including lock cases in high-traffic openings such as offices, schools, healthcare buildings and multi-tenant residential properties served by commercial hardware.
