Hyundai Elantra Key Replacement
Hyundai Elantras have been on Dallas–Fort Worth roads since the 2007 era, and across 4 key generations this model has used 4 different key systems — transponder + separate rke remote; transponder ignition key + separate rke remote (fcc osloka-360t); flip remote-head; smart-proximity. 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 Elantra Keys
The table below is our verified key reference for the Hyundai Elantra — 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 |
|---|---|---|---|---|
| Elantra | 2007–2010 | Transponder + separate RKE remote | Philips Crypto ID46 / PCF7936 | HY15 |
| Elantra | 2011–2016 | Transponder ignition key + separate RKE remote (FCC OSLOKA-360T) | Texas Crypto DST80 / ID6E-MA *or* Philips PCF7952A | HY18R |
| Elantra | 2017–2020 | Flip remote-head | Texas DST AES 128-bit (Smartra 3) | HY18R |
| Elantra | 2021–2026 | Smart-proximity | Texas DST AES 128-bit (Smartra 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 Elantra specifically, the immobilizer families we see are: Philips Crypto ID46 / PCF7936, Texas Crypto DST80 / ID6E-MA *or* Philips PCF7952A, Texas DST AES 128-bit (Smartra 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 Elantra Key FAQ
I lost the only key to my Elantra. 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 Elantra call.
My Elantra is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Elantras (2021–2026) use a proximity smart key on the Texas DST AES 128-bit (Smartra 3) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Elantra is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2007–2010 generation (transponder + separate rke remote), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
