Our take on the OBD Tool Smart Car Key Programmer Tool and Keyless Entry Remote Replacement for Chrysler 200/300/ and for Dodge Charger/Challenger with FCC: M3N-40821302

This is an OBD-based programmer plus a 433 MHz smart key remote for 2015–2017 Chrysler 200 and 2019–2021 Chrysler 300, Dodge Charger and Challenger. It lets an owner pair a new smart key at home in about 5–10 minutes instead of paying a dealer to do it. It needs one working remote to authorize programming and a 12+8 cable adapter to link the tool to the car. The catch is fit: the original key's FCC ID, chip and buttons must match, so it only suits owners who already have a working key for these specific models.

Questions and answers

Can I program a key if I have no working remote?
No. The tool needs one working remote to start the ignition and authorize programming. Without a working key, a dealer or locksmith is the usual route.
Do I need extra hardware to connect it?
Yes. A 12+8 cable adapter is required to connect the programmer to the vehicle, and it is not part of the tool itself.
Will it work on my Chrysler or Dodge?
Only if your car is a 2015–2017 Chrysler 200 or a 2019–2021 Chrysler 300, Dodge Charger or Challenger, and your original key matches the 433 MHz frequency, FCC ID M3N-40821302 and 4A chip.
Do I have to cut the emergency key blade?
No. The blade does not need to be cut for programming. Cutting is only about having a physical key to use in the door or ignition.
How long does programming take?
About 5–10 minutes once the tool and adapter are connected and a working remote is on hand.
Is this an official Chrysler or Dodge tool?
No. It is an aftermarket OBD programmer from autokey max, intended for owners to program their own vehicles.
