Keyhole - Wikipedia

A traditional keyhole for a warded lock.

A keyhole (or keyway) is a hole or aperture (as in a door or lock) for receiving a key.^[1] Lock keyway shapes vary widely with lock manufacturer, and many manufacturers have a number of unique profiles requiring a specifically milled key blank to engage the lock's tumblers.
