The Injection Fob is a strengthened two-piece replacement case designed to upgrade the weak factory key fob housing. Built from high-strength, impact-resistant ABS plastic, this design uses socket-head cap screws instead of a snap-fit shell, creating a more rugged and durable construction. It reuses your existing internal components and features a reinforced key-ring hole to eliminate the common breakage found in OEM fobs. Includes panic button. Assembly requires the included 7/64" Allen key. Made in the USA.
