LYFUCESS Jeep Compass Replacement Key Fob 2017-2023 Smart Proximity 433 MHz with Transponder & Battery

This compact remote is designed as a direct-fit aftermarket replacement for Jeep Compass models from 2017 through 2023. It includes the required transponder chip and battery so a dealer or qualified locksmith can program the unit to your vehicle. The casing and buttons match the original layout used on compatible Compass remotes, but this product does not carry Jeep branding and is not an OEM item.

How do I confirm this fob works with my Jeep Compass?

Confirm compatibility by checking three key identifiers on your existing remote: the FCC ID, the part number, and the operating frequency. If your original key shows FCC M3N-40821302 (or M3N40821302) and a part number like 68250346AB, 68250337AB, 68417821AA, or 68417821AB, this replacement is intended to match.

• Verify FCC ID: M3N-40821302 (sometimes printed without dashes)
• Confirm part number matches one of the listed P/Ns
• Check frequency: 433 MHz must match your vehicle

What steps are needed to program the new key fob?

This replacement requires professional programming; it cannot be self-programmed. Take the fob to an authorized dealer or a locksmith with the necessary diagnostic tools. The uncut physical blade must also be cut to your vehicle’s door/ignition profile by a professional.

• Bring vehicle and proof of ownership to dealer or locksmith
• Have the uncut key blade cut to match your existing key
• Professional tools will be used to sync the transponder chip and remote functions

What comes in the box and what should I expect from quality?

The replacement arrives with a pre-installed battery and integrated transponder chip, ready for programming. Each unit is inspected and tested before shipment to ensure consistent electronic performance. The shell and buttons are manufactured to function like the factory remote but intentionally omit any Jeep logos.

• Includes battery and embedded chip for vehicle recognition
• Durable aftermarket housing built to withstand daily use
• Pre-shipment electrical testing for button and transmitter function

What after-sales support and restrictions apply?

LYFUCESS offers a customer support window for replacement or refund if issues arise within 90 days of purchase. Keep in mind this is not an original equipment manufacturer (OEM) remote, so any dealership pricing or warranty coverage tied to OEM parts may differ. Returns and replacements are handled through LYFUCESS customer service.

• 90-day support for defects — contact customer service for options
• No OEM branding included; aftermarket product only
• Professional cutting and programming required — sold as a blank/unprogrammed unit

Who this product is for: Owners of Jeep Compass models from 2017 to 2023 who need a cost-effective replacement remote that matches FCC M3N-40821302 and the listed part numbers, and who can access dealer or locksmith programming services. It’s also suitable for buyers who want a tested aftermarket option with included battery and chip, but do not require factory logos or OEM packaging.
