The Injection Fob is a two-piece replacement case designed to upgrade the weak factory Toyota/Lexus key fob shell. Molded from high-strength, impact-resistant ABS plastic, this bolt-together housing uses socket-head cap screws for a tougher and more reliable design than the OEM snap-fit case. Assembly requires the included 3/32" Allen key. Made in the USA.
