2015-2017 Chrysler 200 Key Fob: Programming, Common Problems, and Replacement Guide
This guide covers common failures, mandatory programming requirements, and how to choose the right used smart key for your 2015-2017 Chrysler 200.
- Programming by a qualified automotive locksmith or a dealer is mandatory for any new or used key fob; it is not a DIY task.
- Before purchasing, you must verify the FCC ID is M3M-40821302 and that the button configuration matches your original fob.
- The most common problem is a "Key Fob Not Detected" message, which should first be troubleshooted by replacing the CR2032 battery.
- A used OEM fob can be a cost-effective option, but it must be electronically unlocked before it can be programmed to your car.
Symptoms of a Failing Chrysler 200 Key Fob
When a key fob begins to fail, the symptoms can range from a minor annoyance to preventing you from starting the car. Always try replacing the CR2032 battery before 🎬 Watch: How to easily replace your key fob battery assuming the fob itself is bad.
- "Key Fob Not Detected" Message: This is the most common complaint. The dashboard information center will display this message when you try to start the car. This indicates the car's internal antenna cannot receive a signal from the fob.
- Intermittent or No Response: The buttons for lock, unlock, trunk, or remote start may work sporadically or not at all. You might have to press a button multiple times for it to register.
- Reduced Remote Range: You may find you have to be much closer to the vehicle than usual for the remote functions to work. This is a classic sign of a weak battery but can also indicate a failing transmitter in the fob.
- Inability to Start the Vehicle: In a complete failure, the car will not recognize the fob at all, and the push-to-start button will be unresponsive. You can often use an emergency override by pushing the start button with the nose of the key fob itself. 🎬 See how to use the emergency override to start your car
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While there are no major recalls specifically for the key fob on the 2015-2017 Chrysler 200, some related issues are worth noting.
- TSB for Key Fob Issues: One Technical Service Bulletin mentions that engineering is investigating conditions where a key fob is unable to be programmed, has no function, or experiences a low battery condition. This acknowledges that programming and power issues are known problems.
- Electrical System Recalls: The 2015 model year had recalls related to electrical connectors that could cause the engine to stall or shift to neutral, which could be misdiagnosed as a key fob or security issue. Another recall for 2015-2017 models involved reprogramming the Powertrain Control Module (PCM) for an issue with the cruise control system. While not directly related to the fob, these highlight the complexity of the vehicle's electronics.
Pro Tip: If you get the "Key Fob Not Detected" message, try placing the key fob very close to the start/stop button and pressing the button with the fob itself. This can often bypass a weak signal and allow you to start the car.
Programming: The Most Critical Step
A replacement keyless entry transmitter for a 2015-2017 Chrysler 200 MUST be professionally programmed to the vehicle. This is not a do-it-yourself procedure. The fob is an integral part of the car's anti-theft immobilizer system.
Locksmith vs. Dealer Programming
You do not have to go to a dealership for programming. A qualified automotive locksmith can program a new or used OEM key fob to your vehicle, often for a lower price than the dealer. Locksmiths use specialized diagnostic tools that connect to the vehicle's OBD-II port 🎬 Watch a locksmith program a new smart key via the OBD-II port to register the new key with the car's computer. During the programming process, the vehicle's unique PIN code must be read from the computer. All existing and new keys must be present at the time of programming.
Buying a Used Keyless Entry Transmitter for Your Chrysler 200
Purchasing a used OEM key fob can be a smart way to save money, as they are often more durable than cheap aftermarket alternatives. However, you must verify compatibility and condition carefully.
- Verify the FCC ID: The most important step is to match the FCC ID. For this Chrysler 200, the correct FCC ID is M3M-40821302. This number is usually printed on the back of the key fob case. A fob with a different FCC ID will not work.
- Check the Button Configuration: Ensure the button layout matches your original remote. These fobs came in 4-button (Lock, Unlock, Trunk, Panic) and 5-button (adding Remote Start) configurations.
- Physical Inspection: Check the fob's case for cracks or signs of being pried open aggressively, which could indicate internal damage. Ensure the button pads feel responsive and are not worn through.
- Ask About its History: A used key fob that was previously programmed to another vehicle must be electronically "unlocked" by a locksmith with special tools before it can be programmed to your car. Always confirm with the seller if the fob is unlocked and ready for programming.
Warning: Do not purchase a key fob that looks similar but has a different FCC ID or part number. Chrysler uses many visually identical fobs that are not interchangeable electronically.

Frequently Asked Questions (FAQ)
Can I program a new Chrysler 200 key fob myself?
No. The 2015-2017 Chrysler 200 does not have a self-programming procedure. It requires specialized diagnostic equipment connected to the vehicle's OBD-II port, which only automotive locksmiths and dealerships have.
Why does my car say "Key Fob Not Detected" even with a new battery?
This can happen for several reasons. The key fob itself may have failed internally. There could also be an issue with the car's Radio Frequency Hub (RFH) or antenna, which receives the signal. Lastly, strong radio frequency interference from other devices can sometimes block the signal.
Will a used key fob from another Chrysler 200 work?
Yes, provided it is the correct part with the matching FCC ID (M3M-40821302). However, it must be electronically unlocked by a locksmith before it can be programmed to your specific vehicle. A fob that is still locked to its original vehicle cannot be programmed to yours.
How many keys can be programmed to a Chrysler 200?
You can typically have up to eight key fobs programmed to the vehicle at one time.
