This Injection Fob is a two-piece replacement case designed to upgrade the durability and strength of the factory Toyota key fob. Made from high-strength, impact-resistant ABS (black PC-ABS), it replaces the OEM snap-fit housing with a secure bolt-together design using the included 7/64" Allen key. Built for long-term reliability and proudly made in the USA.
Important Notes
Watch instruction videos before purchasing: Verify your fob matches the compatible style shown.
DO NOT use threadlocker: Loctite and similar products can damage the plastic.

OEM case destruction may be required: The key blade is molded into the original shell and often must be cut out.
Transponder removal varies: Some come out easily; others require cutting or heat. Damage may prevent the vehicle from starting.
Optional replacement key method: A Toyota G-chip key (P/N 89785-08040) can be cut/programmed if you choose not to extract the molded key.
No reprogramming required when reusing OEM components.
