Definition
A toll or duty historically levied for the privilege of loading and unloading merchandise at a key, quay, or wharf. Keyage is a species of toll incident to the use of port infrastructure, paid by merchants or vessel operators to the owner or authority controlling the landing facility. It is functionally identical to wharfage and quayage — the three terms describe the same underlying charge and differ only in spelling conventions and regional usage.

Common Language
Modern common usage (Wiktionary): An alternative form of "quayage."
Historical common usage (Webster's 1913): Wharfage; quayage.
The ordinary and legal meanings here are essentially coextensive — this is a term of trade and port custom rather than a term with a divergent legal sense. The legal significance lies not in a gap between common and legal meaning, but in recognizing that keyage, quayage, and wharfage are interchangeable in historical sources, with the spelling chosen often reflecting the scrivener's preference rather than any substantive distinction.

Common Confusion
KEYAGE / QUAYAGE / WHARFAGE: These three terms describe the same charge and appear interchangeably in historical sources. The variation is orthographic and regional: "key" and "quay" are alternate spellings of the same word, and "wharf" is the more common English form. Researchers encountering any of these terms in port records, customs documents, or municipal ordinances should treat them as synonymous unless context suggests otherwise. Do not assume a document using "keyage" rather than "wharfage" is describing a distinct or lesser right — the distinction is one of spelling, not substance.

Why It Matters in Research
Keyage is an archaic spelling that appears in older English and American legal sources and will surface primarily in pre-twentieth century port records, municipal charters, admiralty proceedings, and customs documentation. Researchers working in those corpora should note:
Spelling instability is significant. "Key" and "quay" were used interchangeably in English legal texts well into the nineteenth century. Index searches limited to one spelling will miss documents using the other. Search strategies should include both forms along with "wharfage" and "quayage."
The charge belongs to a broader category of port and harbor dues — including anchorage, cranage, lastage, and stallage — that appear clustered together in medieval and early modern commercial law texts and port ordinances. Finding keyage in a document is a navigational signal that related charges may be nearby.
American case law is sparse under this precise term. Black's 2nd edition cites Rowan v. Portland, 8 B. Mon. (Ky.) 253, as authority, connecting keyage to American municipal wharf regulation. Researchers pursuing the doctrine in American jurisdictions will find far richer material under "wharfage" than under "keyage" or "quayage."
The Isle of Man note appended to the Black's entries under the KEYS heading is a separate matter entirely — the "Keys" as the twenty-four chief commoners of the Manx legislature is an unrelated term that happens to follow keyage alphabetically in the dictionary. Researchers should not conflate the two.

Historical Dictionary Support
All three source dictionaries agree on the core definition without variation: keyage is a toll for loading and unloading at a quay or wharf. Black's 1st and 2nd editions and Bouvier's differ only in whether they spell the landing place as "key," "wharf," or "quay" — itself a demonstration of the interchangeability noted above.
Black's 2nd edition adds the citation to Rowan v. Portland and appends the secondary entry on KEYS in old English law (guardian, warden, or keeper), which is an entirely distinct term appearing under the same headword due to alphabetical proximity. Historical dictionaries do not flag this potential confusion, which is a gap researchers should keep in mind.
None of the historical sources provide substantive discussion of who could impose keyage, how it was calculated, or how disputes were resolved — reflecting that the charge was governed largely by local custom and port authority rather than uniform common law doctrine. For depth on the regulatory framework, researchers will need to look beyond dictionary sources to admiralty treatises and port-specific records.

Jurisdictional Note
Keyage as a named charge appears predominantly in English and British Commonwealth legal history. In American law, the equivalent charge is almost universally called wharfage and is regulated by state law and, where interstate or foreign commerce is implicated, subject to federal constitutional constraints on state interference with commerce. Researchers should not assume English keyage doctrine maps directly onto American wharfage law without verifying the applicable jurisdictional framework.
