The Ilco X249 key blank (MZ31) is designed for Mazda automotive lock systems that use the MZ31 key profile. This mechanical metal-head key blank is commonly used for duplicating keys for various Mazda vehicles produced before widespread transponder key systems became standard.

Manufactured from nickel-plated brass, the X249 blank offers durability, corrosion resistance, and reliable cutting performance. Its precision blade design allows locksmiths and automotive key specialists to create accurate duplicates that operate properly in compatible ignition, door, and trunk lock cylinders.

The MZ31 profile was used across several Mazda models from the late 1990s through the early 2000s, making the Ilco X249 a commonly stocked key blank for locksmith shops and automotive key services working with older Mazda vehicles.
