Hyundai 4-Button Remote Key Fob (FCC ID OSLOKA-310T) – Guide & Info

Sourcing decisions for the Hyundai 4-Button Remote Key Fob (FCC ID OSLOKA-950T) – Full 4-Button Remote Key Fob (FCC ID OSLOKA-310T) split between OEM and aftermarket paths, and understanding the distinction matters for both vehicle owners and automotive locksmiths. An OEM unit from Hyundai Motor Company carries the factory part quality and is tested to meet the exact electrical specifications of the original, while aftermarket variants of this fob can offer significant cost savings without necessarily sacrificing core functionality. The Hyundai 4-Button Remote Key Fob (FCC ID OSLOKA-310T) operates at 315 MHz and requires proper programming to the vehicle regardless of which sourcing route is chosen. For technicians stocking inventory, every variant should be validated against the FCC ID to ensure compliance. When replacing the Hyundai 4-Button Remote Key Fob (FCC ID OSLOKA-310T), confirm the button count, frequency, and FCC designation before beginning any programming procedure.

Vehicle Compatibility for the Hyundai 4-Button Remote Key Fob (OSLOKA-310T)

This remote is a validated fit for the Hyundai Elantra model years 2006 through 2010. The Elantra in this generation used a 315 MHz remote entry system, and the OSLOKA-310T is the FCC-registered device authorized for that frequency band. Owners of these model-year Elantras who need a replacement remote should look specifically for units bearing this FCC ID to ensure radio compliance and programming compatibility with the vehicle’s receiver module.

It is worth noting that while this remote covers a specific five-year production window, not every Elantra trim within that range necessarily shipped with identical keyless entry hardware. Verifying the FCC ID printed on the back of the original remote—or cross-referencing with the vehicle’s documentation—remains the most reliable way to confirm the correct replacement unit.

315 MHz Frequency and Button Layout

The device transmits at 315 MHz, which is the standard frequency allocation used by many Hyundai car keys & fobs models sold in the North American market during this era. The four-button layout on this fob typically provides lock, unlock, trunk release, and panic functions, giving drivers convenient control over the vehicle’s entry and alarm systems from a reasonable distance.

Because the remote communicates at 315 MHz, it falls under FCC Part 15 regulations. The FCC ID OSLOKA-310T confirms that the device has been tested and authorized to operate within the permitted emission limits at this frequency. Aftermarket replacements that claim compatibility should carry the same FCC ID; units with differing FCC designations may operate at a different frequency or use a different rolling-code protocol, leading to programming failures.

Programming Considerations for Locksmiths

Automotive locksmiths programming the Hyundai 4-Button Remote Key Fob (FCC ID OSLOKA-310T) should be aware that the 2006–2010 Elantra’s remote programming procedure generally involves a specific ignition-cycle sequence or the use of a diagnostic tool to register the new remote’s signal with the body control module. The exact steps can vary depending on whether the vehicle still has a functioning programmed remote available, as some procedures require at least one working fob to enter programming mode.

When no working remote is available, a professional-grade diagnostic tool capable of communicating with Hyundai’s onboard systems is typically required. This device is a standalone remote—it does not contain an integrated key blade or immobilizer transponder chip within the fob housing itself. As such, programming this unit addresses only the keyless entry function; any separate ignition key or transponder concerns are handled independently.

OEM vs. Aftermarket: What to Know

Genuine OEM units sourced through Hyundai dealerships or authorized parts distributors tend to carry a higher price point but come with the assurance of factory-matched electronics and housing quality. The shell construction, button feel, and internal circuit board in an OEM fob are built to Hyundai Motor Company’s specifications, which can mean better long-term durability in the button contacts and battery terminals.

Aftermarket remotes bearing the OSLOKA-310T FCC ID are widely available and represent a cost-effective alternative, particularly for locksmiths maintaining inventory for common service calls. Quality varies by manufacturer, so sourcing from reputable aftermarket suppliers is advisable. Regardless of origin, both OEM and aftermarket versions of this remote use a standard CR2032 battery, which is inexpensive and widely available at retail.

Battery Replacement and Maintenance

The fob’s housing is designed to be opened with a small flat-head screwdriver or a coin inserted into the seam along the edge. Inside, the CR2032 coin cell sits in a clearly marked holder. When signal range begins to decrease—requiring closer proximity to the vehicle for lock and unlock commands to register—battery replacement is typically all that is needed to restore full functionality.

Replacing the battery does not erase the remote’s programming. The rolling code and frequency pairing with the vehicle’s receiver module are stored in non-volatile memory on the fob’s circuit board. After inserting a fresh battery and reassembling the housing, the device should function immediately without any reprogramming steps.

When to Contact a Professional Locksmith

Vehicle owners who have lost all copies of this remote, or whose fob has sustained physical damage to the circuit board, should contact an automotive locksmith experienced with Hyundai systems. A qualified locksmith can source the correct replacement unit, verify the FCC ID match, and program it on-site. This is generally faster and more affordable than scheduling a dealership visit, particularly for a vehicle generation that is now well outside its original warranty period.

For the 2006–2010 Elantra specifically, mobile locksmith services are well-equipped to handle this remote because the programming protocols for this era of Hyundai vehicles are well-documented and supported by most professional diagnostic platforms.
