⭐ The WS21 is a Texas Instruments DST-AES transponder chip, ID 8A with 128-bit AES encryption, in the Hyundai and Kia configuration for models from 2021 to 2026, including the Elantra, Seltos, Creta, Casper and Accent. It is a loose wedge chip for the chip cavity of a transponder key or flip key head. This unit is a genuine factory chip, new and supplied without its original packaging. Locksmiths add it to the immobiliser with a key programmer when building a spare or an all keys lost key.
⚙️ Key features
Texas DST-AES, ID 8A
128-bit AES transponder from the Texas Instruments DST family, the chip type read by the immobiliser on the listed models.
Hyundai and Kia setup
Configured for Hyundai and Kia. The WS21 marking is also sold set up for Toyota H and Subaru as separate parts.
Wedge form factor
Black carbon wedge marked WS21-00, sized for the chip cavity in a transponder key or flip key head.
Factory production
Texas Instruments chip made in Malaysia, new and supplied loose without the original packaging.
💎 Benefits
Right configuration
The Hyundai and Kia version keeps a Toyota or Subaru WS21 out of the job before you cut a blade.
Lower key cost
Rebuild a key around the customer's shell and blade instead of ordering a complete new key.
One part, nine models
A single chip covers nine Hyundai and Kia models from 2021 to 2026, so a small stock serves many jobs.
👥 Who it's for
Automotive locksmiths
Adding a spare or building a key for all keys lost on these Hyundai and Kia models.
Key shops and counter trade
Cutting and programming transponder keys for walk-in customers.
Dealers and garages
Replacing a damaged chip or making a second key before a used car is sold.
🚗 Compatible vehicles
Before ordering, read the chip in the original key: it must report ID 8A (Texas DST-AES). The WS21-00 marking alone does not show the configuration.
