Toyota FJ Cruiser Key Replacement
Toyota FJ Cruisers have been on Dallas–Fort Worth roads since the 2006 era, and across 2 key generations this model has used 1 different key system — transponder (cut). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About FJ Cruiser Keys
The table below is our verified key reference for the Toyota FJ Cruiser — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| FJ Cruiser | 2006–2010 | Transponder (cut) | Texas 4D67 “Dot” (DST40) | TOY43 |
| FJ Cruiser | 2011–2014 | Transponder (cut) | DST80 “G” | TOY43/TOY44 |
Security System & Immobilizer
Toyota’s immobilizer evolved through four transponder families — Texas 4C on 90s cars, the 4D67 “dot” chip, the DST80 “G” chip, and today’s 128-bit “H” chip — before the Smart Key System brought push-to-start proximity fobs. Each family needs different programming procedures, which our equipment covers end to end.
On the FJ Cruiser specifically, the immobilizer families we see are: Texas 4D67 “Dot” (DST40), DST80 “G”. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Toyota FJ Cruiser Key FAQ
I lost the only key to my FJ Cruiser. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common FJ Cruiser call.
Will a hardware-store copy start my FJ Cruiser?
It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.
