The Ilco X4 key blank (MZ4) is designed for older Mazda vehicle locks and related automotive applications. It is used for duplicating keys that operate compatible ignition, door, and trunk lock systems depending on the vehicle model and year.

Manufactured from nickel-plated brass, the X4 blank provides durability, corrosion resistance, and consistent performance during key cutting. Its precision profile allows locksmiths and automotive key specialists to produce accurate duplicates that function properly in compatible vehicle lock cylinders.

Because many older Mazda vehicles used mechanical metal-head keys before the introduction of transponder systems, the Ilco X4 remains a commonly stocked blank for locksmith shops, automotive key services, and restoration work involving legacy Mazda vehicles.
