• OEM Part Numbers: 95440-D4000 or 95440-D5000

• FCC IDs: SY5JFFGE04 or SY5QEFGE04

• Frequency: 433 MHz

• Transponder Chip: HITAG 3 (ID47)

• Key Type: 4-Button Proximity Smart Key (Lock, Unlock, Trunk, Panic)

⚠️ Critical "System Upgrade" Warning

For the 2016 redesign, Kia completely overhauled the Optima's security architecture, upgrading the immobilizer system to the much more secure Hitag 3 (ID47) platform and shifting the frequency to 433 MHz. If you are supplying your own key, you must verify it matches one of the FCC IDs listed above. Older Optima smart keys from 2011–2015 (which used ID46 chips at 315 MHz) will permanently fail to communicate with this fourth-generation computer.

👨‍🔧 Specialized Technician & Diagnostic Approach

Programming this generation of proximity key requires advanced OBDII diagnostic intervention and vehicle-specific PIN code calculation. Our certified technicians will connect directly to your Optima's Smart Key Control Module (SMK) using dealer-level tools to securely register the new ID47 transponder chip and proximity antenna signals. We also utilize a computerized laser-milling machine to precisely cut the high-security internal "sidewinder" blade to match your original door lock specifications.
