Replacement Fob M3N40821302 433MHz

This replacement keyless entry remote uses part number M3N40821302 and operates at 433MHz with a 46 chip. It fits Dodge Charger 2011-2018, Dodge Dart 2013-2016, Dodge Challenger 2015-2018 and Chrysler 300 2011-2018. The unit includes a built-in door key and four buttons for lock, unlock, panic and trunk release. A CR2032 lithium battery is supplied.

Sustained Use Reliability

The remote provides sensitive response and fast wireless control during daily operation. Its coin-cell battery maintains the 433MHz signal for repeated locking, unlocking and trunk cycles. Performance stays consistent as long as the battery voltage remains adequate. The non-OEM accessory is designed for regular vehicle access rather than continuous transmission.

Installation And Programming

The fob measures 7.3x3.7cm and arrives with the battery installed. A qualified locksmith or dealership must program the remote and cut the door key before use. A working original key fob is required to add this new unit to the vehicle system. Verify the OE number and appearance match your current remote before purchasing to avoid fitment issues.

Questions about this item

Does the 433MHz M3N40821302 fob draw noticeable power from the CR2032 battery during daily use?

The remote uses a standard CR2032 lithium coin cell; typical current draw is very low, so the battery lasts months under normal locking, unlocking, panic and trunk operations.

What tools or existing keys are required before a locksmith can program this M3N40821302 replacement?

You need at least one working original key fob for the vehicle and the new fob must be cut and programmed by a qualified locksmith or dealership.

Will the 46-chip M3N40821302 work alongside an older factory fob on a 2015 Dodge Challenger?

Yes, the 46-chip remote is compatible with 2015-2018 Challenger models and can coexist with existing factory fobs once programmed.
