Product identity

The Em-D-Kay 224523 is a solid brass mortise cylinder lock finished in US3 polished brass. It measures 1-1/2 inches and suits residential or commercial doors needing a standard replacement cylinder.

Re-keying and cam flexibility

The cylinder uses a pin tumbler mechanism that can be re-keyed to match existing keys. A standard cam is included and the design accepts different cams so installers can adapt it to various mortise lock bodies without replacing the whole lock.

Door thickness and mortise compatibility

Verify the door thickness matches the 1-1/2 inch cylinder length before ordering. Confirm the existing mortise lock body accepts a standard cam and that the keyway suits your keying requirements.

Questions about this item

How often should the pin-tumbler mechanism in this mortise cylinder be lubricated?

Apply a dry graphite lubricant to the keyway once a year or whenever the key begins to stick; avoid oil-based products because they attract dust that can gum up the pins.

What stops the solid brass cylinder from turning freely in the mortise body after years of daily operation?

The standard cam engages the lock body, and the brass housing resists deformation; the cylinder will bind first if the door shifts or the mortise pocket wears out of square.

Does the polished brass finish discolour or generate noticeable heat when the lock is operated continuously throughout the day?

Brass conducts heat poorly and the cylinder has no moving parts that create friction beyond the key turn, so the finish simply develops a natural patina over time without measurable temperature rise.
