Durability is a critical feature for car key blanks. They must resist wear and corrosion over time, as keys are frequently inserted and turned in ignition and door locks.

Most blanks are made from high-quality metals such as nickel silver, which offers a good balance of strength and ease of cutting. Stainless steel blanks are favored for their corrosion resistance and durability, especially in humid or harsh environments. Some manufacturers also use brass for its machinability and decent corrosion resistance.

Car key blade blanks come in several forms to accommodate different key technologies:

Traditional Mechanical Keys: Simple blade blanks that are cut to match the mechanical lock pattern of the car doors and ignition.

Transponder Keys: Blanks designed to house a transponder chip, which communicates with the vehicle's immobilizer system for security. The blade must fit both mechanically and electronically.

Flip or Switchblade Keys: These are blade blanks integrated into a folding key fob mechanism, requiring specific shapes and sizes for proper function.

Laser Cut or Sidewinder Keys: These keys have a more complex design with cuts on the side rather than the edge, requiring specialized blade blanks compatible with laser cutting machines.
