Replace your fragile factory key shell with the AJT Design Injection Fob case built 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 — but careful component transfer is critical.
