Toyota Yaris Key Replacement
Toyota Yariss have been on Dallas–Fort Worth roads since the 1999 era, and across 3 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 Yaris Keys
The table below is our verified key reference for the Toyota Yaris — 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 |
|---|---|---|---|---|
| Yaris | 1999–2005 | Transponder (cut) | Texas 4C (non-crypto) | TOY43 |
| Yaris | 2006–2011 | Transponder (cut) | Texas 4D67 “Dot” (DST40) | TOY43 |
| Yaris | 2012–2018 | 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 Yaris specifically, the immobilizer families we see are: Texas 4C (non-crypto), 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 Yaris Key FAQ
I lost the only key to my Yaris. 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 Yaris call.
Will a hardware-store copy start my Yaris?
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.
My Yaris is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1999–2005 generation (transponder (cut)), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
