Experiencing issues with your 2017 Chrysler 300 Key Fob can be a frustrating ordeal. If you’re down to just one key or facing a non-functional fob, you’re likely seeking solutions. The bad news is that your 2017 Chrysler 300 likely uses an RFH2 key fob system, which presents unique challenges compared to older systems. Unlike the simpler RFH1 fobs, the RFH2 system incorporates a dynamic or “rolling” PIN, making DIY programming and even locksmith services more complex.
This means that readily available smartphone apps designed for earlier Chrysler models won’t be able to extract the necessary key code. Furthermore, many general locksmiths may lack the specialized and often expensive equipment required to program a new key fob for these later model FCA (Fiat Chrysler Automobiles) vehicles. Even locksmiths who do possess the necessary tools often incur higher costs due to the technology investment and the necessity of connecting online with Chrysler in real-time to obtain a temporary security code. Consequently, opting for a locksmith might not result in significant savings compared to a dealership.
However, the good news is that you are not without options. Let’s explore the available paths to get you back on track with a functioning 2017 Chrysler 300 key fob.
Option 1: Obtaining Your Key Code and Programming at the Dealership
As the registered owner of your 2017 Chrysler 300, you have the right to request a printout of your key code from the parts department of your local Chrysler dealership. While some dealerships might charge a nominal fee for this service, it should be considerably less expensive than full key programming, perhaps around $20. It’s important to understand that dealerships face daily limits on the number of key codes they can retrieve from FCA. Therefore, patience and a friendly approach can go a long way, especially if they are balancing your request with potential high-revenue customers needing urgent key replacements.
The most straightforward solution is often to purchase new, aftermarket key fobs and have them programmed by the dealership. You can find compatible aftermarket 2017 Chrysler 300 key fobs online for significantly less than dealer prices. Once you’ve acquired a couple of new fobs, contact your local Chrysler dealership’s parts department to inquire about their key fob programming service costs. It’s reasonable to aim for a total labor charge of around one hour of work, encompassing the programming of all new fobs and the cutting of the physical blade keys, if applicable. Scheduling this service with the dealership where you originally purchased your vehicle might increase your chances of a favorable outcome. Alternatively, demonstrating that you are a parts department customer when making your request can also be beneficial. Remember, a polite and patient demeanor often yields the best results.
Option 2: DIY Programming with AlfaOBD (Advanced Users)
For the more technically inclined and adventurous 2017 Chrysler 300 owner, a DIY approach to key fob programming is possible using AlfaOBD software and a compatible ELM327 Bluetooth OBD adapter. AlfaOBD is a powerful diagnostic tool that provides access to many of the same diagnostic and configuration options used by dealership service departments.
While the author successfully programmed an older RFH1 fob using AlfaOBD on a different vehicle, the RFH2 system in your 2017 Chrysler 300 presents a greater challenge. It might be possible to extract the necessary key code using AlfaOBD, but this functionality is not guaranteed for newer models and RFH2 systems. The understanding is that the security code for RFH2 systems changes regularly, possibly every 24 hours, and accessing the current code may require dealership-level access to activate the RF hub.
If you are able to retrieve the key code using AlfaOBD, or obtain it from the dealership as mentioned in Option 1, you should then be able to proceed with programming the new key fob yourself using AlfaOBD and your ELM327 adapter. This method offers considerable cost savings on labor and provides you with a valuable diagnostic tool for your vehicle.
Whether you choose to program the key fob yourself or at the dealership, you also have the option of having the physical blade keys cut. Dealerships can typically cut these keys to code, but this service may be more expensive than obtaining a “follow-cut” key from a local hardware store. Dealerships may also offer blade key cutting for a minimal cost when you are already having them program the fob. However, if you are comfortable primarily relying on the electronic key fob functions, skipping the physical blade key cutting can be a further way to reduce costs.
Even if you find that you cannot retrieve the key code or program the fob yourself using AlfaOBD in this instance, investing in AlfaOBD and an ELM327 adapter is still a worthwhile endeavor. AlfaOBD provides extensive diagnostic capabilities for FCA vehicles, enabling you to troubleshoot various issues, perform system checks, and even customize vehicle settings. For example, users have been able to utilize AlfaOBD to modify daytime running light settings or enable performance pages within the Uconnect system. Exploring online forums dedicated to RAM trucks or FCA vehicles can provide a wealth of information and guidance on leveraging the full potential of AlfaOBD.
Conclusion
Dealing with a 2017 Chrysler 300 key fob issue doesn’t have to be a dead end. While the RFH2 system introduces complexities, you have viable options. From obtaining your key code and professional programming at the dealership to exploring DIY programming with AlfaOBD, you can choose the path that best suits your comfort level and technical expertise. Remember to approach dealerships with patience and politeness, and consider the long-term benefits of tools like AlfaOBD for comprehensive vehicle diagnostics and customization.
