Replace your fragile factory key shell with the AJT Design Injection Fob case for 5th gen Toyota 4Runner models without push button start and select other Toyota key applications. This rugged two-piece replacement housing is injection molded from high-strength, impact-resistant ABS plastic (black version uses PC-ABS) and upgrades the OEM snap-fit case to a screw-together design for improved strength and serviceability.
Your original key blade, electronics, battery, and transponder chip are reused, so no reprogramming is required when installed correctly.
