The Injection Fob is a two-piece replacement case designed to upgrade the factory Toyota key fob with a stronger, bolt-together design. Made from high-strength, impact-resistant PC-ABS plastic, this case reuses your existing valet key, electronics, battery, buttons, and seal (not included). Instead of a snap-fit like the OEM shell, this housing assembles using socket-head screws for durability and reliability. A 3/32" Allen key is included. Made in the USA.

No Threadlocker: Do NOT use Loctite or any type of threadlocker.
