Upgrade your factory smart key shell with the AJT Design Injection Fob case for the 5th gen Toyota 4Runner Limited with push button start. This rugged two-piece replacement housing is built from high-strength, impact-resistant ABS plastic and replaces the factory snap-fit shell with a screw-together design for improved durability and long-term reliability.
By removing the valet/emergency key storage found in the OEM case, this version achieves a smaller, stronger, and more symmetrical design while still allowing reuse of your original internal electronics and seal.
