The Injection Fob is a two-piece replacement case that upgrades the factory Toyota key fob with a stronger, more durable PC-ABS housing. Designed for long-term reliability, it reuses your OEM electronics, battery, and seal, and bolts together using included socket-head screws for a rugged, no-nonsense assembly. Made in the USA.
Important Notes
Valet/emergency key does NOT store inside the case — removed to create a smaller, stronger, symmetrical design.
Not interchangeable with the 2016+ V2 Tacoma version — exterior looks similar, but internal geometry is different.
DO NOT use threadlocker (Loctite) — it can damage the plastic.
OEM electronics, battery, and seal must be reused (not included).
Assembly requires the included 3/32" Allen key.
