Experiencing unusually short battery life in your 2017 Lincoln MKX key fob can be frustrating. It’s a common concern for many vehicle owners, and understanding the potential causes and solutions is key to resolving this issue. If you’re finding yourself frequently replacing the battery in your key fob, you might be wondering if there’s a problem with your fob itself or if there are other factors at play.
First, let’s confirm the correct battery size for your 2017 Lincoln MKX key fob. The 2017 Lincoln MKX key fob uses a CR2026 battery. This is a widely available lithium coin cell battery that provides the necessary power for your key fob’s functions, including remote locking/unlocking, starting your vehicle remotely, and activating the panic alarm. Using the correct battery type is crucial for optimal performance and to avoid any potential damage to your key fob.
If you are using the correct CR2026 battery and still experiencing short battery life, there are a few potential reasons for this. One possibility is a fault within the key fob itself. A malfunctioning fob could be drawing power even when not in use, leading to rapid battery depletion. To investigate this, consider a simple test: if you have a second key fob for your 2017 Lincoln MKX, try using it as your primary fob. If the battery life in the second fob is normal, then the issue is likely with your original fob.
Another factor to consider, especially if your 2017 Lincoln MKX is still under warranty, is to have your key fobs checked by a certified Lincoln dealer. New Lincoln vehicles typically come with a bumper-to-bumper warranty that may cover issues with key fobs. A dealer’s service department can diagnose any potential problems with your fob and determine if it needs replacement under warranty. They can also check for any software or hardware issues in your vehicle that might be contributing to excessive battery drain in the key fobs.
For context, many Lincoln MKX owners experience a much longer battery life in their key fobs, often lasting for a couple of years or more under normal usage. If you are replacing your key fob battery every few months, as mentioned in some user experiences, it’s definitely worth investigating further. Switching to your spare fob and consulting with your Lincoln dealer are good first steps in troubleshooting and resolving this issue, ensuring you have reliable key fob operation for your 2017 Lincoln MKX.
It’s always a good idea to keep a spare CR2026 battery on hand so you’re prepared when it’s time to replace it. You can typically find these batteries at most drugstores, supermarkets, and online retailers. Regularly checking your key fob battery and addressing any signs of short battery life will help ensure you’re never caught off guard by a dead fob battery.
