AJT DESIGN Injection Fob IF004 - BLACK for 4Runner

The Injection Fob is a two-piece plastic replacement case for select Toyota key fobs. Injection-molded from high-strength, impact-resistant ABS plastic, this upgraded housing uses bolt-together construction for superior durability compared to the OEM snap-fit design. Existing electronics, battery, buttons, and seal transfer directly into the new case. A reinforced key ring hole eliminates the common breakage found on factory fobs. Includes panic button. Assembly requires a 7/64" Allen key (included). Made in the USA.
