AJT DESIGN Replacement Key Fob is a custom, injection-molded rugged case that replaces your OEM Toyota fob shell for Tacoma (2024+), Tundra (2022+), 4Runner (2025+) and Sequoia (2023+).
This replacement key fob case is a direct-fit shell engineered to accept your existing electronics, battery, buttons, seal and valet key, giving your Toyota fob a stronger, more refined enclosure. Built in the USA from high-strength PC-ABS plastic, the case replaces the factory housing (not a cover) to provide a durable exterior, precise button alignment and a choice of button configurations including Gate, Gate/AC, blank space and a red or black panic button.
Yes — AJT DESIGN cases are custom-molded to match the exact dimensions and mounting points used by the listed Toyota models so your OEM electronics and valet key snap into place. Verify your vehicle year and fob type before ordering for the correct button layout.
Installation is designed to be quick and approachable — most customers complete the swap in about five minutes. Your original internals are transferred into the new shell and the case is secured with included black socket head cap screws for a solid, OEM-feel assembly.
AJT DESIGN uses injection-molded PC-ABS, a strong, impact-resistant thermoplastic favored for automotive parts. The finish is designed to resist scratch and everyday wear while delivering a rugged aesthetic that looks and feels premium compared with the stock case.
Choose the layout that matches your vehicle's original fob or the functions you plan to keep. If your vehicle lacks a third function, select the Blank space option; if you want remote gate or AC control, select those corresponding button sets. Panic button color can be chosen as red or black to suit preference.
Who is this for: This replacement case is ideal for Toyota owners who want a direct-fit, long-lasting shell that upgrades the look and protection of their factory fob without changing electronics. It suits DIYers comfortable transferring the existing electronics and anyone who prefers a rugged, American-designed part to refresh worn or damaged key fobs for Tacoma (2024+), Tundra (2022+), 4Runner (2025+) and Sequoia (2023+).
Q: Can I reuse my original key electronics and battery?
A: Yes. The AJT DESIGN case reuses your existing electronics, battery, buttons, seal and valet key; those parts are not included.
Q: Do I need special tools to install the case?
A: No special tools—installation uses the included 3/32" allen key and black socket head cap screws and takes about five minutes.
