Replacement Fob for Chrysler 300

This Unique-Bargains keyless entry remote replaces the original fob for Chrysler 300 models from 2019 to 2020. It operates at 433MHz and uses a 4A chip with part numbers M3M-40821302 and 68155687AB. The unit includes a built-in door key and five buttons for locking, unlocking, panic and trunk release. A CR2032 lithium battery is supplied inside the case.

Programming and Fitment Requirements

The remote must be programmed and the door key cut by a qualified locksmith or dealership before it will work with the vehicle. A working key fob is required to add this new remote to the system. Compatibility should be verified against the OE part number and the product images before purchase. The fob also fits Chrysler 200 models from 2015 to 2017 and Dodge Charger and Challenger models from 2019 to 2021.

Non-OEM Alternative for Lost or Damaged Keys

This aftermarket accessory provides a cost-effective substitute when the factory fob is lost or damaged. It is not an OEM part and requires professional programming that may not be supported by all locksmiths. Buyers who cannot access a qualified locksmith or dealership, or who need a fully pre-programmed OEM unit, should consider other sourcing options. The compact case measures 7.3 by 3.7 centimetres.

Questions about this item

How long does the CR2032 battery last under daily use?

The included CR2032 lithium cell powers the 433MHz transmitter; typical life is one to two years depending on how often the five buttons are pressed.

Does the fob get warm or make noise when left in the car all day?

The remote has no moving parts and draws only microamps while idle, so it stays at cabin temperature and is completely silent.

What must I already have before a locksmith can programme this key?

You need at least one working original key fob for the vehicle so the locksmith can add this M3M-40821302 remote to the system.
