AJT DESIGN Injection Fob IF004 - CEMENT for 4Runner (1996-2009)

The Injection Fob is a durable two-piece replacement case for the factory key fob found on select 3rd Gen & 4th Gen 4Runners and 1st Gen Sequoias. Molded from high-strength, impact-resistant ABS plastic, this upgraded design uses socket-head cap screws instead of a weak OEM snap fit.
Your existing electronics, battery, buttons, and seal transfer directly into the new case (not included with purchase). The reinforced key-ring loop eliminates the common breakage found in factory housings. Includes panic button.
Assembly requires the included 7/64" Allen key.
Made in the USA.
