The Injection Fob is a two-piece plastic case that replaces the factory key fob housing. Injection molded from high-strength, impact-resistant ABS plastic, this upgraded fob uses a bolt-together design with socket-head cap screws for a tougher, more secure feel. Assembly requires the included 3/32" Allen key. Made in the USA.
