The AJT Design Injection Fob case is a rugged two-piece replacement shell that upgrades the factory key fob housing on select early Toyota applications. Built from high-strength, impact-resistant ABS plastic, this case replaces the weak snap-fit factory shell with a screw-together design for improved durability and long-term reliability.
Instead of replacing your entire key fob, this case allows you to reuse your original electronics, battery, buttons, and seal, transferring them into a stronger outer housing. A reinforced key ring hole helps eliminate one of the most common factory failure points.
