The AJT Design Injection Fob case is a rugged two-piece replacement shell for 5th gen Toyota 4Runner models without push button start and select other Toyota key applications. Built for durability and long-term use, this case replaces the factory snap-fit shell with a screw-together design using socket head hardware for a stronger, more serviceable housing.
Each case is injection molded from high-strength, impact-resistant ABS plastic (black version uses PC-ABS). Your existing key blade, electronics, battery, and transponder components are reused and transferred into the new case — no reprogramming required when installed correctly.
