BMW Remote Control Battery Discharged How to Fix It and Maintain Your Key FobA BMW remote control is an essential component of modern vehicles, offering convenience and security with features like keyless entry, remote start, and trunk release. However, like all electronic devices, the battery in your BMW remote control can eventually lose its charge. A discharged remote control battery can cause frustration, especially if you’re unable to access your car or use its features. In this topic, we will explore how to fix a BMW remote control with a discharged battery, signs to look out for, and how to prevent battery issues in the future.

Understanding the BMW Remote Control Battery

BMW remote controls, also known as key fobs, operate on small batteries that power the communication between the fob and the vehicle. These batteries are typically long-lasting but will eventually need to be replaced. The most common battery type for BMW key fobs is the CR2032 lithium coin cell battery, which is inexpensive and widely available.

When the battery starts to run low, you may notice that the range of your key fob decreases or that certain features like remote unlocking or starting the car no longer work. The key fob may also stop working completely once the battery is fully discharged.

Signs Your BMW Remote Control Battery is Discharged

Before jumping into fixing a discharged key fob, it’s important to recognize the signs that indicate a battery problem. Common symptoms of a discharged BMW remote control battery include

  1. Weak or Reduced Range You may notice that the range at which the remote control can operate your car has significantly decreased. For instance, you may have to be closer to the vehicle to unlock or lock it remotely.

  2. Non-responsive Remote If your key fob fails to respond when pressing the buttons, it’s a clear sign that the battery might be dead or dying.

  3. Warning Message on Dashboard In some BMW models, the vehicle may display a message on the dashboard indicating that the key fob’s battery is low.

  4. No Remote Start or Trunk Release If the remote start feature or trunk release isn’t working, it’s possible that the key fob’s battery is discharged.

If you experience any of these signs, it’s time to replace the battery in your BMW remote control.

How to Replace the Battery in a BMW Remote Control

Replacing the battery in a BMW remote control is a relatively simple process that you can do yourself with minimal tools. Follow these steps to replace the battery in your key fob

Step 1 Gather the Necessary Tools

Before you begin, gather the following items

  • A small flat-head screwdriver or coin

  • A new CR2032 battery

  • A clean cloth or surface to work on

Step 2 Open the Key Fob

  1. Locate the seam of the key fob. Depending on the model, the fob may have a small slit or groove where you can separate the two halves.

  2. Use the flat-head screwdriver or a coin to gently pry apart the key fob. Be careful not to damage the fob or the internal components.

Step 3 Remove the Old Battery

Once the fob is open, you’ll see the old battery. It’s typically held in place by a small clip or tab.

  1. Remove the old battery by gently lifting it out of its compartment. Take note of the orientation of the battery, as you’ll need to insert the new one in the same direction.

  2. Dispose of the old battery properly. Many electronics stores offer battery recycling services if you need a place to dispose of it.

Step 4 Insert the New Battery

  1. Place the new CR2032 battery into the compartment with the correct polarity (positive side facing up). Ensure it’s seated securely in place.

  2. Snap the key fob back together. Gently press the two halves of the fob together until they click into place.

Step 5 Test the Key Fob

Once the new battery is in place and the fob is reassembled, test all functions to ensure everything is working properly. Try locking and unlocking your car, using the remote start, and activating other features like the trunk release. If everything works as expected, you’ve successfully replaced the battery.

When to Seek Professional Help

In most cases, replacing the battery in your BMW remote control is a straightforward task that can be done at home. However, there may be instances when you should seek professional help

  1. If the Remote Still Doesn’t Work If you’ve replaced the battery and your key fob is still not working, there may be a deeper issue with the remote control, such as a malfunctioning circuit or internal component.

  2. Key Fob Is Damaged If the key fob has physical damage, such as cracks or broken buttons, replacing the battery may not fix the problem. In this case, it may need to be repaired or replaced.

  3. Programming Issues Occasionally, the key fob may need to be reprogrammed after the battery is replaced. If you’re unsure of how to reprogram the fob, it’s best to consult your BMW dealership or a professional locksmith.

Preventing Future Key Fob Battery Issues

To extend the life of your BMW key fob battery and avoid unexpected issues, follow these simple tips

  1. Keep the Key Fob Clean Dirt and debris can accumulate inside the key fob and affect its performance. Clean your key fob regularly with a soft cloth, especially around the buttons and seams.

  2. Avoid Excessive Exposure to Heat Prolonged exposure to heat can shorten the lifespan of the key fob battery. Avoid leaving your key fob in direct sunlight or in hot environments, such as a car parked under the sun for long periods.

  3. Replace the Battery Periodically Even if your key fob is still working, it’s a good idea to replace the battery every 2-3 years as a preventive measure. This ensures that your key fob continues to function optimally.

  4. Check for Firmware Updates Occasionally, BMW may release software or firmware updates for your key fob that can improve its performance. Check with your dealership to ensure your fob is up to date.

A discharged BMW remote control battery can be a frustrating problem, but it’s easy to fix with the right tools and a little know-how. By replacing the battery in your key fob, you can restore its functionality and continue enjoying the convenience of keyless entry, remote start, and other features. Remember to follow the steps carefully, and if you encounter any issues that can’t be resolved on your own, don’t hesitate to consult a professional for assistance. Proper maintenance and periodic battery replacements can help prevent key fob issues and keep your BMW running smoothly for years to come.
