Ever had that sinking feeling when your car battery dies and your key fob decides to take a vacation? It’s like a double whammy of inconvenience hitting you at the worst possible moment. But fret not, because in this article, we’ve got your back! We’re here to unravel the mystery behind why your key fob isn’t playing nice after a battery mishap.
Check Your Key Fob Battery
When your car battery dies, it can often lead to your key fob malfunctioning. This situation can be frustrating, especially if you’re unsure whether the key fob battery is the culprit. Here’s what you can do to check your key fob battery:
- Look for Symptoms: If pressing the buttons on your key fob isn’t eliciting a response from your vehicle, it’s time to investigate the key fob battery.
- Locate the Battery Compartment: Most key fobs have a small slot for the battery. It might require a small screwdriver to open it.
- Inspect the Battery: Once you have access to the battery compartment, check the battery type and its condition. A CR2032 battery is a common type used in key fobs.
- Replace the Battery: If your key fob battery is indeed the issue, find a suitable replacement battery and swap it out following the manufacturer’s instructions.
- Reprogram (if needed): In some cases, after changing the battery, you may need to reprogram your key fob to establish communication with your vehicle.

Remember, taking care of your key fob battery is as essential as maintaining your car’s battery.
Try Manual Key Entry
When your car battery dies and the key fob stops working, don’t worry. You always have the option of using the manual key entry. Here’s what you can do:
- Locate the manual key: Look for the physical key slot on your car door handle. It’s usually hidden to prevent tampering but can be easily accessible once you know where to look.
- Insert the key: Gently insert the manual key into the designated slot until it fits snugly. Be patient and careful to avoid any potential damage.
- Turn the key: Once the key is fully inserted, turn it in the direction that unlocks the door. This may vary depending on your car’s make and model.
- Access your vehicle: With the key turned, you should be able to unlock the door manually and gain access to your vehicle.
- Reminder: While the key fob is undoubtedly convenient, knowing how to use the manual key entry can save you from being stranded in situations like this. So, familiarize yourself with this process before you actually need it.
- Additional tip: If your car has a push-button start, you might need to place the key fob against the start button for the car to recognize the fob’s signal even after using the manual key entry.
Reprogram Your Key Fob
If your car battery died and the key fob isn’t working, reprogramming it can solve the issue without the need for professional help. Here’s how you can do it yourself:
- Step 1: Get in your car and close all doors.
- Step 2: Insert your key into the ignition, but don’t turn it.
- Step 3: Press any button on the key fob and hold it for a few seconds.
- Step 4: Remove the key from the ignition and release the button.
- Step 5: Test your key fob to see if it’s working now.
