This Injection Fob is a two-piece replacement case engineered to upgrade the durability and strength of the factory Toyota key fob. Made from impact-resistant PC-ABS plastic, it replaces the OEM snap-fit housing with a bolt-together design using included socket-head screws for a more rugged and serviceable construction. Assembly requires the included 3/32" Allen key. Made in the USA.
