A dead key fob battery can be a major inconvenience, especially when you’re in a hurry. If you own a BMW 5 Series, you know that the key fob is a vital part of your daily driving experience. This comprehensive guide will walk you through everything you need to know about your BMW 5 Series key fob battery, from identifying the signs of a dying battery to replacing it yourself.
Recognizing a Dying BMW 5 Series Key Fob Battery
Before you start digging through drawers for a spare battery, it’s essential to confirm that your key fob battery is indeed the culprit. Here are some telltale signs:
- Decreased Range: You might notice that you need to be much closer to your car for the key fob to lock or unlock the doors.
- Intermittent Functioning: The key fob may work sporadically, sometimes responding and sometimes not.
- Warning Messages: Your BMW may display warnings on the dashboard, such as “Key Fob Battery Low” or a similar message.
- No Response: The most obvious sign – your key fob doesn’t respond at all, no matter how many times you press the buttons.
Which Battery Does My BMW 5 Series Key Fob Use?
Most BMW 5 Series key fobs use a CR2032 battery, a common type of lithium coin battery readily available at most stores that sell batteries. You can usually find them in supermarkets, drugstores, electronics stores, and online.
How to Change Your BMW 5 Series Key Fob Battery
Replacing the battery in your BMW 5 Series key fob is a relatively simple process that you can easily do yourself at home. Here’s a step-by-step guide:
- Locate the Battery Compartment: Look for a small slot or notch on the side or back of your key fob. This is where the battery compartment is located.
- Open the Compartment: Use a small flat-head screwdriver or a similar tool to carefully pry open the battery compartment cover.
- Remove the Old Battery: Gently remove the old CR2032 battery. Be careful not to touch the battery terminals with your fingers.
- Insert the New Battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up, as indicated in the compartment.
- Close and Test: Securely close the battery compartment cover. Test your key fob by pressing the buttons to ensure it’s working correctly.
