Mitsubishi OEM Remote Head Key – PCF7941 Chip, MIT11 Blade

Fitments for the Mitsubishi OEM Remote Head Key include the Mitsubishi Lancer (2008–2020) and Mitsubishi Mirage (2012–2024). Across both platforms, the unit combines mechanical ignition access with integrated remote-lock electronics operating at 315 MHz. Each Mitsubishi OEM Remote Head Key communicates with the vehicle’s immobilizer module during a coded handshake mediated by the PCF7941 transponder chip. Owners replacing this key should expect a programming procedure that pairs both the transponder and the remote functions to the vehicle’s ECU. When ordering a Mitsubishi OEM Remote Head Key, confirm the blade profile (MIT11) and FCC ID compatibility to ensure a proper match.

Transponder and Radio Specifications for the Mitsubishi OEM Remote Head Key

The PCF7941 transponder chip at the heart of this remote head key is manufactured by Philips. This dual-function IC integrates a crypto-transponder with a remote keyless entry (RKE) transmitter in a single silicon package, which is why it appears in combined remote-head-key form factors rather than in separate fob-and-blade configurations. The transponder side handles the immobilizer challenge-response sequence, while the RF section transmits lock, unlock, and trunk-release commands at 315 MHz.

Two FCC IDs are associated with this product line: OUCG8D-625M-A and OUCJ166N. These registrations cover the 315 MHz operating band and confirm compliance with Part 15 emission limits. Locksmiths should verify which FCC ID appears on the original key being replaced, because internal component revisions between the two registrations can affect programming tool compatibility.

MIT11 Blade Profile and Mechanical Considerations

The MIT11 keyway is a standard Mitsubishi key & lock service high-security profile used across a number of the brand’s passenger vehicles. It features a single-track internal milling pattern cut into the blade’s flat face, which engages wafer tumblers inside the ignition cylinder. Key-cutting machines that support MIT11 include most modern electronic duplicators with a Mitsubishi card or code database loaded. The blade is integral to the remote head key housing—it does not detach—and must be cut before transponder programming begins, because the physical key must turn the ignition to the correct position during the pairing sequence on many Mitsubishi models.

When duplicating the blade from a worn original, locksmiths should decode the existing wafers rather than copy by tracing, since wear on an older key can introduce enough deviation to cause binding or a no-start condition. If the original is unavailable, pulling the code from the door or ignition cylinder is the next option.

Programming Procedure Overview

Programming this key typically involves two distinct stages: transponder registration and remote-function pairing. The transponder stage writes the PCF7941’s crypto credentials into the vehicle’s immobilizer ECU. Most aftermarket diagnostic tools that support Mitsubishi immobilizer systems—such as the Smart Pro, IM608, or TCODE—can handle this step, though technicians should confirm that the tool’s software version includes coverage for the specific model year being serviced.

The remote-pairing stage can often be completed through an on-board procedure on certain Lancer and Mirage model years. The typical on-board sequence requires cycling the ignition and pressing the lock button within a timed window, though the exact steps vary by year. Locksmiths who lack documentation for the specific model year should fall back to tool-based remote programming to avoid lockouts caused by failed manual attempts.

Both stages must succeed for the remote head key to function fully. A unit that starts the engine but does not operate the door locks—or vice versa—indicates an incomplete pairing on one side of the dual-function chip.

Vehicle Fitment Details

The validated fitments for this key span two Mitsubishi Motors model lines:

• Mitsubishi Lancer (2008–2020) – Covers the tenth-generation Lancer sedan across its full production run, including sport and evolution-branded trims that shared the same immobilizer platform.
• Mitsubishi Mirage (2012–2024) – Covers the sixth-generation Mirage hatchback and the closely related Mirage G4 sedan. Despite running-change updates to infotainment and safety electronics over this span, the immobilizer and RKE subsystem remained compatible with the same remote head key.

Before ordering, verifying the FCC ID printed on the back of the customer’s existing key is the most reliable way to confirm which variant is needed. Cross-referencing the VIN through a parts lookup tool adds a second layer of confirmation.

OEM vs. Aftermarket Considerations

Genuine Mitsubishi Remote Head Key (FCC ID MIT11R) – Specs & Program keys use OEM-grade PCF7941 transponder ICs and factory-matched RF components. Aftermarket alternatives are available at lower price points but may use cloned or compatible chipsets that behave differently during programming. Specifically, some aftermarket PCF7941-compatible chips require an additional “generate key” step in the programming tool before they will register with the vehicle’s ECU. Locksmiths should note whether the replacement unit is a true OEM part or an aftermarket equivalent, and adjust the programming workflow accordingly.

For vehicle owners, the practical difference is minimal once the key is correctly programmed—both OEM and quality aftermarket units deliver the same start-and-lock functionality. The risk lies in cheaper aftermarket housings with inferior button membranes or poorly seated blade tangs, which can lead to premature mechanical failure.
