The Injection Fob is a two-piece plastic case that replaces the factory case that comes with the vehicle. Designed exclusively for the 5th Gen 4Runner Limited with push-button start, this upgraded housing is injection-molded from high-strength, impact-resistant PC-ABS plastic. Existing electronics, battery, and seal are reused (not included). Instead of an annular snap fit, the case bolts together using socket-head screws for a more rugged, secure build. Assembly requires the included 3/32" Allen key. Made in the USA.
Important Notes
Valet/emergency key does NOT store inside this case.
Not compatible with the 2016+ Tacoma V2 case — same outer shape, different internal geometry.
For push-button-start 4Runner Limited models ONLY.
DO NOT USE THREADLOCKER (e.g., Loctite) — can damage the plastic.
Electronics, battery, and seal must be reused from your OEM fob.
