The AJT Design Injection Fob case is a rugged two-piece replacement shell built specifically for the 5th gen Toyota 4Runner Limited with push button start. This upgraded housing replaces the factory snap-fit case with a screw-together design for improved strength, durability, and long-term reliability.
By removing the internal valet/emergency key storage found in the OEM case, this design becomes smaller, stronger, and more symmetrical while still reusing your original internal electronics and seal.
Important note
Vehicle fitment: 5th gen Toyota 4Runner Limited (2010+)
Start type: Push button start only
Valet key storage: Not supported in this case design
Model difference: Not the same internal geometry as the 2016+ Tacoma V2 version (outer shape may look similar, inside is different)
