The 2018 Dodge Journey is a reliable SUV, and like many modern vehicles, it comes with a convenient key fob for keyless entry and ignition. Understanding your 2018 Dodge Journey Key Fob is crucial for smooth vehicle operation. Whether you need to program a new key fob, replace a lost or damaged one, or troubleshoot common issues, this guide provides essential information for Dodge Journey owners.
Understanding Your 2018 Dodge Journey Key Fob
The key fob for your 2018 Dodge Journey is more than just a key; it’s a sophisticated piece of technology that allows for remote locking/unlocking, starting your vehicle (depending on the model), and sometimes even remote start functionality. These key fobs typically operate on radio frequencies to communicate with your vehicle’s Wireless Ignition Module (WIM), also sometimes referred to as the Sentry Key Immobilizer Module (SKIM) or Sentry Key Remote Entry Module (SKREEM).
Programming a 2018 Dodge Journey Key Fob: Dealership vs. DIY
When it comes to programming a new key fob for your 2018 Dodge Journey, you generally have two options: visiting a dealership or attempting a DIY approach.
Dealership Programming:
Dealerships have the specialized equipment and diagnostic tools necessary to program key fobs for your Dodge Journey. This usually involves connecting your vehicle to their system and using proprietary software to sync the new key fob with your car’s computer.
- Pros: Guaranteed to work (if the key fob is compatible and the process is done correctly), professional service, and they can handle complex situations.
- Cons: Can be significantly more expensive than DIY options, and requires an appointment and trip to the dealership. As the original article mentions, dealerships might charge a programming fee even if the key fob doesn’t work immediately, so clarify their policy beforehand.
DIY Programming:
The original article mentions that once you have two working keys, you can program spare keys yourself. While some older vehicles allow for simple DIY key fob programming procedures that you can find online or in the owner’s manual, for a 2018 Dodge Journey, DIY programming is generally NOT possible without specialized aftermarket tools. The “Google procedure” mentioned in the original article might be applicable to very basic key fobs or older models, but for modern vehicles like the 2018 Journey with security systems, it’s unlikely to work for full key fob programming (ignition and remote functions).
However, the original article touches on an important point: having two working keys simplifies things. If you already have two programmed key fobs, in some cases, you might be able to use a basic procedure (detailed in your owner’s manual if available, or through credible online resources for your specific model year – always verify the source) to program additional remotes for remote entry functions, but not for the ignition key portion without proper tools.
Aftermarket Scan Tools for Key Programming:
The author of the original article mentions using Autel MD802 and Foxwell NT510 scan tools. They highlight that newer software updates for tools like the Foxwell NT510 may now offer key programming capabilities for Chrysler vehicles, including the Dodge Journey.
- Pros: Potentially more affordable than dealership programming in the long run if you need to program keys frequently or for multiple vehicles. Offers more control and convenience for DIY enthusiasts and mechanics.
- Cons: Requires purchasing a scan tool, which can be an upfront investment. Requires technical knowledge to operate the tool and perform the programming procedure correctly. Compatibility and functionality can vary between scan tools and software versions. It’s essential to verify that the specific scan tool and software version you are using explicitly support key programming for the 2018 Dodge Journey.
If you’re considering this route, research compatible scan tools and their capabilities carefully. Ensure the tool you choose is compatible with your 2018 Dodge Journey and specifically lists key programming as a supported function for your vehicle model year.
Key Fob Recall and Replacement
The original article mentions a recall that potentially covered replacement of programmed keys, even non-OEM keys. While this is interesting anecdotal information, it’s crucial to check for official recalls related to key fobs for your 2018 Dodge Journey through the official Dodge/FCA (now Stellantis) website or the National Highway Traffic Safety Administration (NHTSA) website. Recalls are VIN-specific, so you’ll need your Vehicle Identification Number to check.
If there is an active recall related to key fobs, your dealership should replace or reprogram keys as part of the recall remedy, potentially free of charge. As the original author experienced, you might need to be persistent and possibly contact FCA/Stellantis directly to ensure they honor the recall terms, especially for spare keys you’ve programmed yourself.
Key Programming Limits and WIM Module
It’s important to note the limitation on the number of keys that can be programmed to your 2018 Dodge Journey’s WIM module. As mentioned in the original article, there’s a finite number – around 7 or 8 – of keys that the system can recognize. Once this limit is reached, you won’t be able to program any additional keys without potentially needing to reset or replace the WIM module, which can be a more complex and costly procedure.
This limit is generally not a concern for most owners, but it’s something to keep in mind if you are frequently programming new keys or have accumulated several spare keys over time.
Troubleshooting Common 2018 Dodge Journey Key Fob Issues
- Dead Battery: This is the most common issue. The key fob uses a small battery (usually a CR2032 or similar). Replacing the battery is a simple DIY task. Refer to your owner’s manual for instructions on how to open the key fob and replace the battery.
- Key Fob Not Working Intermittently: Could be a weak battery, but also might indicate a problem with the key fob itself or the vehicle’s receiver. Try cleaning the battery contacts in the key fob.
- Key Fob Completely Unresponsive: Could be a dead battery, a malfunctioning key fob, or a problem with the vehicle’s WIM module. Try the spare key if you have one. If neither key works, the issue might be with the vehicle.
- “Key Not Detected” Message on Dashboard: This often indicates the vehicle is not recognizing the key fob signal. Try replacing the battery. If the problem persists, it could be a key fob issue or a problem with the vehicle’s key detection system.
Conclusion
Understanding your 2018 Dodge Journey key fob is key to avoiding inconvenience and potential costs. While dealership programming offers a guaranteed solution, exploring aftermarket scan tools might be a viable option for DIY enthusiasts. Always check for recalls and be aware of the key programming limits of your vehicle. For simple issues, battery replacement is often the first and easiest fix. If you encounter persistent problems, consulting a qualified mechanic or dealership is recommended to ensure proper diagnosis and repair of your 2018 Dodge Journey key fob system.
