Experiencing issues with your car remote can be frustrating, especially when the unlock button suddenly stops working. You’re not alone. Many car owners encounter problems with their key fobs, and understanding the potential causes and solutions can save you time and money. Let’s delve into the common reasons behind a malfunctioning car remote unlock button and explore how to address them.
One of the first things to consider, even though you’ve checked it, is the remote battery. While you mentioned checking the battery, it’s worth double-checking with a fresh battery or a battery tester to rule out a weak battery entirely. Sometimes, a battery might seem okay but still lack the power to properly transmit the signal, particularly for functions like unlocking.
If the battery isn’t the culprit, the issue might lie within the key fob itself. Over time, the internal button contacts can wear out or become misaligned due to regular use or accidental drops. Moisture or debris entering the fob can also interfere with the button’s functionality. Visually inspect the button area for any signs of damage or dirt accumulation.
Another potential cause could be synchronization or programming issues. Although less frequent for just one button to fail, it’s possible that the remote’s unlock function has somehow become desynchronized with your car’s receiver. In some cases, especially after battery changes or electrical glitches, the key fob might need to be reprogrammed to communicate correctly with your vehicle again.
Now, let’s consider solutions and replacement options. You mentioned concerns about getting a new key programmed at the dealer being expensive. That’s a valid point, and exploring alternatives is wise.
Purchasing an OEM (Original Equipment Manufacturer) key fob online can be a more cost-effective approach than going directly to the dealership. Websites specializing in car keys often offer genuine OEM remotes at competitive prices. When considering this option, it’s crucial to verify compatibility with your specific car model and year. While online compatibility checkers can be helpful, double-checking with the seller or a locksmith regarding the part number and FCC ID is always recommended to ensure you’re getting the correct remote for your 2013 Edge SEL with a 3-button fob.
You raised a valid question about reprogramming. Before purchasing a new key, it might be worthwhile to inquire with a dealer or a qualified locksmith about reprogramming your existing remotes. Explain that the lock button on the problematic fob still works. They might be able to diagnose if it’s a programming issue rather than a hardware failure of the unlock button itself. Reprogramming could potentially restore the unlock function without needing a new remote, saving you significant expense.
If reprogramming isn’t the solution and you opt for a new OEM key, you’re correct that key cutting and programming are the next steps. A professional locksmith is typically equipped to cut the physical key portion to match your ignition and door locks. Furthermore, many locksmiths have the necessary tools and expertise to program the new remote to your vehicle, often at a lower cost than dealerships.
Regarding DIY programming, some car models do allow for self-programming of remotes using specific sequences involving the ignition and door locks. However, this capability varies greatly depending on the make, model, and year of the vehicle. For a 2013 Ford Edge, it’s advisable to research specific DIY programming procedures for your model or consult your owner’s manual. Keep in mind that even with DIY programming, you’ll still need the key cut by a professional if the new remote comes with an uncut key blade.

In conclusion, when your car remote unlock button stops working, start with basic troubleshooting like battery checks and visual inspection. Explore reprogramming options with a dealer or locksmith before immediately assuming you need a full replacement. If replacement is necessary, consider OEM keys from reputable online sources and utilize professional locksmith services for key cutting and programming. By systematically investigating these possibilities, you can effectively address the issue and regain full functionality of your car remote.
