MechanMagic Hyundai Elantra Key Fob Remote Replacement 2016-2020 433MHz Pre-tested with Battery

MechanMagic replacement key fob fits 2016–2020 Hyundai Elantra vehicles using part 95430-F2300 (OSLOKA-423T) at 433MHz and arrives pre-tested with battery and electronics ready for programming.

If you lost or damaged your original Elantra key fob, this MechanMagic remote provides a direct, cost-effective substitute. It matches the OEM part numbers and frequency used on many 2016–2020 Hyundai Elantra models and is supplied with the internal circuit and battery already installed. Because the transmitter is sold blank, a qualified locksmith or dealership must perform vehicle programming; the unit does not support push‑start smart keys and is intended for Elantra models with standard keyed ignitions.

Will this remote work with my Hyundai Elantra?

Check compatibility by matching the car's remote part number and frequency rather than only relying on the model year. This MechanMagic fob supports Hyundai part number 95430-F2300 and FCC ID OSLOKA-423T and operates at 433MHz, which differs from 315MHz variants used in other markets.

How do I get this key fob programmed and will it work on my car immediately?

The replacement must be programmed to your vehicle by a qualified locksmith or a Hyundai dealership; it will not operate out of the box.
