The Injection Fob is a two-piece plastic case that replaces the factory key fob housing with a stronger, bolt-together design. Injection molded from high-strength, impact-resistant ABS plastic, this case uses socket-head cap screws for improved durability compared to the OEM snap-fit design. Assembly requires the included 3/32" Allen key. Made in the USA.
