Hyundai Tucson Key Replacement
Hyundai Tucsons have been on Dallas–Fort Worth roads since the 2005 era, and across 4 key generations this model has used 4 different key systems — transponder; transponder / flip (fcc tq8-rke-4f25 late); smart-proximity (fcc tq8-fob-4f07); smart-proximity (fcc tq8-fob-4f11). 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 Tucson Keys
The table below is our verified key reference for the Hyundai Tucson — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Tucson | 2005–2009 | Transponder | Philips Crypto ID46 / PCF7936 | HY15 |
| Tucson | 2010–2015 | Transponder / flip (FCC TQ8-RKE-4F25 late) | Philips Crypto 2 / ID46 / PCF7952A | KIA7 / HY18R |
| Tucson | 2016–2017 | Smart-proximity (FCC TQ8-FOB-4F07) | Philips ID47 / Hitag 3 | HY18R (emergency insert) |
| Tucson | 2018–2021 | Smart-proximity (FCC TQ8-FOB-4F11) | Philips ID47 / Hitag 3 | HY18R (emergency insert) |
Security System & Immobilizer
Hyundai moved from ID46-era transponders and flip keys to Hitag3 ID47 smart keys, with the newest models on ID4A encryption. Chip family determines the programming path, and we match it by VIN.
On the Tucson specifically, the immobilizer families we see are: Philips Crypto ID46 / PCF7936, Philips Crypto 2 / ID46 / PCF7952A, Philips ID47 / Hitag 3. 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.

Hyundai Tucson Key FAQ
I lost the only key to my Tucson. 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 Tucson call.
My Tucson is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Tucsons (2018–2021) use a proximity smart key on the Philips ID47 / Hitag 3 system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Tucson is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2005–2009 generation (transponder), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my Tucson in DFW?
