This listing is for one uncut round-headed GM-branded S1098H / B45 trunk / glovebox key for 1969, 1973, 1977, 1981 GM passenger cars (Chevrolet, Pontiac, Buick, Cadillac, Oldsmobile). If your trunk key has a small letter 'H' or 'B45' stamped on it, this key blank should fit. This is a secondary key, which means it will fit the trunk and glovebox, and possibly the door locks (although note that some cars use the primary / ignition key to open the doors).

From 1968 to 1982, the GM key blanks went in 4 year cycles, so this should fit GM vehicles for the following years (NB This system wasn't always strictly followed by GM, so please check whether your existing key has a stamped letter or reference before purchase):

1969, 1973, 1977, 1981.

May also fit later model GM locks. Check your key for a stamped letter.

Please see my other listings for other classic American key blanks. The primary / ignition key for the above years is P1098E / B44 and should be stamped with a letter 'E'.
