Losing or having a malfunctioning key fob for your Dodge Durango can be a frustrating experience, especially when you need to get going. Modern vehicles, like the Dodge Durango, rely heavily on key fobs for various functions, including starting the engine. However, being stranded without a working key fob doesn’t necessarily mean you’re completely stuck. This guide will explore the methods you can use to start your Dodge Durango even when your key fob is not functioning.
Understanding Key Fob Issues and Initial Checks
Before assuming the worst, it’s important to understand common key fob issues that might prevent your Durango from starting. The most frequent culprit is a dead or weak battery in your key fob. Like any battery-powered device, key fobs rely on a small battery to transmit signals to your vehicle. When this battery dies, the fob may become unresponsive, preventing you from unlocking or starting your Durango remotely.

Quick Checks:
-
Battery Replacement: The first and easiest step is to try replacing the battery in your key fob. Refer to your Durango’s owner’s manual for instructions on how to open the key fob case and replace the battery. Usually, it’s a common CR2032 or similar button cell battery, readily available at most drugstores or electronics stores.
-
Physical Key: Most key fobs for Dodge Durangos contain a physical key hidden inside. Look for a small release button or latch on your key fob. Releasing this will allow you to slide out a traditional metal key. This key can be used to manually unlock the driver’s side door.

Starting Your Durango with the Physical Key
Once you’ve accessed the physical key, you can use it to unlock your Dodge Durango. However, simply unlocking the door might not be enough to start the engine, especially if your vehicle is equipped with an immobilizer system, which is common in modern cars to prevent theft.
Starting Procedure:
-
Enter the Vehicle: Use the physical key to manually unlock the driver’s side door. Be prepared for the car alarm to potentially sound when you open the door without using the fob.
-
Locate the Ignition: Insert the physical key into the ignition cylinder. In most Dodge Durangos, this is located on the steering column.
-
Turn the Key: Turn the key in the ignition cylinder just like you would in an older vehicle without a key fob. If the immobilizer system recognizes the physical key (which it should, as it’s designed to work with your vehicle), the engine should start.
Note: The exact starting procedure might slightly vary depending on the specific model year and trim level of your Dodge Durango. Always consult your owner’s manual for the most accurate instructions for your vehicle.
Addressing Potential Wireless Control Module (WCM) Issues in Older Durangos
If replacing the key fob battery and using the physical key doesn’t work, and you own an older Dodge Durango (specifically built before May 17, 2004), there’s a possibility of a Wireless Control Module (WCM) issue.
According to some reports from Dodge forums, Durangos manufactured before this date may have a defective WCM module. This module is responsible for recognizing the RFID chip in your key fob. A faulty WCM might prevent new RFID codes from being added to the vehicle, which can become a problem when you need to program a new key or if the system malfunctions.

What to do if you suspect a WCM issue:
-
Check Build Date: Locate the build date of your Dodge Durango. This information is usually found on a sticker on the driver’s side doorjamb. If your Durango was built before May 17, 2004, the WCM issue is a possibility.
-
Dealership Visit: If you suspect a WCM problem, the best course of action is to visit a certified Dodge dealership. According to the forum information, Chrysler was aware of this issue and would replace the WCM under warranty when a Durango owner requested a new transponder key. While your vehicle might be out of warranty now, a dealership can diagnose the WCM and advise on the best repair options.
Seeking Professional Help for Key Fob and Starting Problems
If you’ve tried the basic troubleshooting steps and your Dodge Durango still won’t start without a key fob, it’s time to seek professional assistance.
When to call a professional:
-
Physical key doesn’t work: If the physical key doesn’t start the engine, there might be a more complex issue with the immobilizer system, ignition cylinder, or other vehicle components.
-
Suspect WCM issue (older Durango): Dealership diagnosis is recommended for WCM problems.
-
Lost all keys: If you’ve lost all your key fobs and physical keys, you’ll need a locksmith or dealership to create a new key and program it to your vehicle.
Options for professional help:
-
Dodge Dealership: Dealerships have specialized diagnostic equipment and access to genuine Dodge parts. They can diagnose complex issues, replace the WCM if needed, and program new keys.
-
Automotive Locksmith: A qualified automotive locksmith can often handle key and key fob issues, including cutting new keys and programming transponder chips. They may be a more cost-effective option than a dealership for key-related problems.
Conclusion
While key fobs offer convenience, knowing how to start your Dodge Durango without one is essential in case of malfunction or loss. Starting with basic checks like battery replacement and utilizing the physical key can often resolve the issue. For older Durangos, being aware of potential WCM problems is crucial. When in doubt or if basic troubleshooting fails, seeking professional help from a dealership or automotive locksmith will ensure your Durango gets back on the road safely and efficiently. Remember to consult your Dodge Durango owner’s manual for specific instructions and information related to your vehicle model.
