Which vehicles does this key fob fit?

This replacement is made for vehicles that use FCC ID M3M-40821302 / M3N40821302 and matches several OEM part numbers. Always confirm fit using your car’s FCC ID or consult the vehicle fitment tool before purchase.

• Chrysler 300 — compatible model years around 2011–2016 depending on configuration

How is the fob prepared and what’s included?

SUPALAND tests each remote with locksmith-grade tools before shipping, and installs the battery and internal electronics so the buyer receives a complete physical unit. The package contains one keyless-entry remote ready for professional programming.

• Pre-tested electronics to ensure functionality on arrival
• Battery pre-installed so the fob powers up immediately
• One fully assembled remote included in the box
• Clear compatibility and part-number references for verification

Can I program this fob myself or how do I get it programmed?

This SUPALAND fob requires programming by an auto locksmith or a dealership; it does not support consumer self-programming. Professional programming links the remote’s internal code to your vehicle’s immobilizer and keyless entry system safely.

• Bring the fob and vehicle to a locksmith or dealer for on-site programming
• Programming ensures remote operates locks, trunk release, and panic functions if supported
• Keep proof of purchase and vehicle ownership handy for dealer programming

What OEM part numbers and FCC IDs does it replace?

The SUPALAND replacement is intended to work as a hardware substitute for specific factory part numbers and FCC IDs used by Chrysler and Dodge. Verify against the numbers stamped on your original remote or the vehicle’s owner materials.

• Compatible FCC IDs: M3M-40821302, M3N40821302
• Common OEM part numbers replaced: 68066349AD, 68066349AG, 68066349
• Check your original remote or dealer documentation to confirm exact match

Who this is for: This replacement remote is intended for owners of compatible Chrysler and Dodge vehicles who need an economical, like-new hardware replacement—either to restore lost functionality or to keep as a programmed spare. It’s ideal for buyers comfortable arranging professional programming through a locksmith or dealership rather than attempting DIY coding.
