Experiencing issues with your Ford Taurus key fob can be frustrating. A key fob that suddenly stops working can lock you out of your car, disable remote start, and generally cause inconvenience. The good news is that often, the problem isn’t as serious or expensive as you might initially think. This guide will walk you through common reasons why your Ford Taurus key fob might not be working and explore troubleshooting steps and solutions, saving you potentially hundreds of dollars at the dealership.
One of the most common culprits behind a malfunctioning key fob is simply a dead battery. Like any battery-powered device, the battery in your key fob will eventually run out of juice. If your key fob is working intermittently or has completely stopped responding, replacing the battery is the first and easiest step to take. Typically, Ford Taurus key fobs use a CR2032 battery, which is widely available at drugstores, supermarkets, and online retailers. Consult your owner’s manual for specific instructions on how to open your key fob and replace the battery.
Sometimes, even with a fresh battery, your Ford Taurus key fob might still not work. In these cases, the issue could be related to synchronization or programming. Key fobs and car security systems communicate wirelessly, and occasionally this connection can be disrupted. While a simple resynchronization procedure isn’t always available for all Ford Taurus models through owner methods, attempting to reprogram the key fob could be the next logical step.
For Ford Taurus owners with two original, working keys, there’s a self-programming procedure that can be attempted to add a new key or potentially re-sync existing ones. It’s important to note that this method relies on having two already programmed keys. If you only have one working key or none, you’ll likely need professional assistance from a locksmith or dealership. Here’s how to attempt key fob programming if you have two working keys:
- Insert an existing, working key into the ignition cylinder.
- Turn the ignition to the “ON” position (just before starting the engine) and then back to “OFF”. Ensure the ignition is in the “ON” position for at least one second.
- Remove the first key and, within ten seconds, insert a second working key. Turn the ignition to “ON” and then back to “OFF” again, holding it in the “ON” position for at least one second but no more than ten seconds. Remove this key.
- Immediately insert the new, unprogrammed key (or the key fob you are trying to re-sync) within twenty seconds and turn the ignition to “ON”. Leave it in the “ON” position for at least one second and then turn back to “OFF”.
- If the programming is successful, the security light on your dashboard should illuminate for approximately three seconds. This indicates that the new key or key fob has been successfully programmed.
If you don’t have two original working keys, or if the above procedure doesn’t work, you’ll need to seek professional help. Automotive locksmiths are often a more affordable alternative to dealerships for key fob programming. As one user shared, they were quoted significantly less at a locksmith compared to initial expectations. Locksmiths specializing in automotive keys have the necessary tools and expertise to diagnose key fob issues, reprogram existing fobs, and even create new keys if needed. They often have invested in equipment like OBDII programmers, which connect to your car’s computer system to manage key and immobilizer functions.
For those who are comfortable with a bit of DIY car maintenance and plan to keep their Ford Taurus for the long term, investing in tools like ForScan and an ELM327 OBDII adapter can be a worthwhile option. ForScan is a software application designed for Ford vehicles that allows for in-depth diagnostics, programming, and customization. Combined with a compatible OBDII adapter, you can access your Ford Taurus’s computer system to perform key programming yourself. While there is a small upfront cost for the software and adapter, it can save you money on diagnostic fees and key programming costs in the long run, as mentioned in the original user experience.
In conclusion, if your Ford Taurus key fob is not working, start with the simplest solution: replacing the battery. If that doesn’t resolve the issue and you have two working keys, try the self-programming procedure. If these steps fail, or if you lack two working keys, contacting an automotive locksmith is a cost-effective next step. For the DIY enthusiast, exploring tools like ForScan can offer more advanced diagnostic and programming capabilities for ongoing car maintenance. By understanding these options, you can effectively troubleshoot and resolve your Ford Taurus key fob issues without unnecessary expense.
