Keylessbest Replacement Mitsubishi Key Fob Remote OUC644M-KEY-N — 4-Button 315MHz for 2008–2020 Lancer/Outlander/Mirage

Keylessbest's OUC644M-KEY-N is a 4-button replacement remote keyed to 315MHz designed to replace worn or lost Mitsubishi key fobs from 2008–2020 (Lancer, Outlander Sport, Mirage).

If your original Mitsubishi remote shows cracked plastic, weak buttons, or no longer transmits, this aftermarket Keylessbest unit gives you a like-for-like physical replacement that houses your OEM chip and supports dealer or locksmith programming. It arrives brand-new and unprogrammed, so a qualified locksmith or dealer must program it to your vehicle's immobilizer and remote system. Verify the FCC ID and part number on your old fob before ordering to ensure compatibility.

Will this Keylessbest remote work with my Mitsubishi model and year?

The Keylessbest OUC644M-KEY-N is built to match the FCC ID and physical form factor used across many Mitsubishi models from 2008 through 2020. Compatibility depends on the exact FCC ID (OUC644M-KEY-N) and the vehicle's remote frequency (315MHz). Always compare the back of your original fob and consult your dealer or locksmith if unsure.

• Designed for models including Lancer, Outlander Sport, Mirage (2008–2020 range)
• Confirm FCC ID OUC644M-KEY-N and 315MHz frequency on your original fob
• If your original differs, this part may not program correctly

How do I get the Keylessbest key fob programmed?

This product ships unprogrammed for security; a dealer or qualified locksmith must program it to your car's immobilizer. Many locksmiths can transfer your key’s transponder and sync remote functions in a single visit, but procedures vary by dealership and model year. Contact a local professional beforehand to confirm they support this FCC ID and frequency.

• Bring proof of ownership and the vehicle for on-site programming
• Confirm locksmith or dealer supports OUC644M-KEY-N and 315MHz programming
• Some shops can clone your OEM chip into the new shell for a faster setup

What are the build and performance differences versus an OEM fob?

Keylessbest emphasizes improved button action, stricter pre-shipment testing, and materials chosen for durability. The housing is lightweight and wear-resistant with enhanced water resistance and longer battery life. It is intended to hold the original OEM chip and be indistinguishable in function once programmed.

• More responsive button design for quicker operation
• Better wear-resistance and water-proofing than many aftermarket options
• Holds OEM transponder chip for security and compatibility

What should I check before purchasing this replacement fob?

Prior to buying, verify the FCC ID, part number, and physical appearance of your existing remote to ensure a match. Confirm a local locksmith or dealer can program the part for your specific Mitsubishi model and year. Remember this unit arrives unprogrammed—installation and programming are the buyer's responsibility.

• Compare the FCC ID (OUC644M-KEY-N) printed on your old fob
• Confirm frequency is 315MHz and button layout matches (4 buttons)
• Check a locksmith or dealer can perform programming beforehand
