Signs Your Key Fob Battery Needs Replacing

It’s easy to overlook the signs of a dying key fob battery, mistaking them for other car troubles. Here are some common red flags:

Decreased Range: You have to stand closer to your car than usual for it to unlock.
Intermittent Functioning: The key fob works sometimes but not others, or only responds after multiple presses.
Dashboard Warning: Your BMW may display a “Key Fob Battery Low” warning message.
Slow Response Time: There’s a noticeable delay between pressing the button and your car responding.

What Type of Battery Does a 2013 BMW 135i Key Fob Use?

Your 2013 BMW 135i key fob uses a CR2032 battery, a common type found at most electronics stores.

How to Replace Your 2013 BMW 135i Key Fob Battery

Replacing your key fob battery is a quick and easy DIY project. Here’s a step-by-step guide:

Locate the Battery Compartment: It’s usually on the back or side of the key fob and may have a small release button or slider.
Open the Compartment: Use a small flathead screwdriver or a fingernail to carefully pry open the compartment.
Remove the Old Battery: Gently pry out the old battery, noting the positive (+) and negative (-) sides for correct placement of the new battery.
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up or as it was with the old battery.
Close the Compartment: Snap the battery compartment cover back into place.
Test the Key Fob: Try locking and unlocking your car to confirm the new battery is working.

Pro Tip from John Miller, Senior Automotive Technician: “When replacing your key fob battery, avoid touching the battery terminals directly. This can drain the battery’s power. Handle the battery by its edges for best results.”

Extending the Life of Your Key Fob Battery

While key fob batteries have a limited lifespan, there are a few things you can do to help them last longer:

Avoid Extreme Temperatures: Extreme heat or cold can shorten battery life. Don’t leave your key fob in direct sunlight or a freezing car for prolonged periods.
Keep it Dry: Moisture is bad news for electronics. Store your key fob in a dry place and avoid getting it wet.
Minimize Unnecessary Button Presses: Every button press uses battery power. Only press the buttons when necessary to conserve battery life.

When to See a Professional

If you’ve replaced the battery and your key fob is still not functioning properly, there may be a more complex issue at play. It’s best to consult with a qualified automotive locksmith or your BMW dealership for further diagnosis and repair.
