The Ilco P1101 GM Key Blank B84 is an uncut metal-head automotive key blank designed for various General Motors vehicles. It is a non-transponder (mechanical) key, meaning no programming is required after cutting.

This key blank is typically used on older GM models, including select Buick, Chevrolet, Oldsmobile, and Pontiac vehicles—especially from the early to mid-1990s. It operates on the GM “J” code series and is compatible with standard key cutting machines, making it a reliable option for locksmiths and automotive service providers.

Manufactured from nickel-plated brass, the P1101 / B84 provides durability and consistent cutting performance. It remains a widely recognized and cross-referenced key blank across multiple manufacturers and supplier catalogs.
