The AJT Design Injection Fob is a rugged, two-piece replacement key case designed to upgrade the factory Toyota H-key shell. Injection-molded from high-strength, impact-resistant ABS plastic, this design replaces the weak OEM snap-fit housing with a bolted construction for improved durability and long-term reliability. Made in the USA, it’s a straightforward solution for owners who want a stronger, more serviceable key case without reprogramming.
