Upgrade your factory smart key with a stronger, rebuildable shell designed for daily use and hard conditions. The AJT Design Injection Fob replaces the OEM snap-fit housing with a rugged two-piece, screw-together case made from high-strength PC-ABS plastic. It’s built for newer Tundra and Tacoma smart keys and lets you reuse your original internal components with no reprogramming required.
Important note

Push-start only: Not compatible with keyed ignition fobs
Component reuse: Valet key, electronics, battery, and seal are reused (not included)
Programming: No reprogramming needed after proper transfer
