Description

One uncut square-headed GM-branded P1098J / B46 ignition key for 1970, 1974, 1978, 1982 GM passenger cars (Chevrolet, Pontiac, Buick, Cadillac, Oldsmobile). If your ignition key has a small letter ‘J’ or ‘B46’ stamped on it, this key blank should fit. This is a primary key, which means it will fit the ignition, and possibly the door locks (although note that some cars use the secondary / trunk 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):

1970 1974 1978 1982

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