A dead key fob battery can leave you stranded, unable to lock or unlock your Honda. Don’t worry! Replacing the battery is a quick and easy task anyone can do. This guide will walk you through the process step by step.
What You’ll Need
- A small flat-head screwdriver
- A new CR2032 battery (available at most hardware and automotive stores)
Locating the Battery Compartment
Most Honda key fobs have a similar design, but there can be slight variations depending on the model and year. Here’s how to locate the battery compartment:
- Examine your key fob: Look for a small seam or groove running along the edge of the fob. This typically indicates the location of the battery compartment cover.
- Find the release button: There is usually a small release button on the back of the fob. This button may be marked with a key symbol or the word “release.”
Opening the Key Fob
- Press the release button: Using your fingernail or the tip of the flat-head screwdriver, gently press the release button.
- Separate the key fob halves: While pressing the release button, carefully separate the two halves of the key fob. You might feel a slight resistance, but the cover should come off easily.
- Identify the battery: Once the key fob is open, you’ll see the CR2032 battery inside.
Replacing the Battery
- Remove the old battery: Use the flat-head screwdriver to gently pry the old battery out of its compartment. Be careful not to damage the contacts.
- Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side faces up.
- Align and snap the fob halves together: Align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.
Testing Your Key Fob
Once you’ve replaced the battery, test your key fob to ensure it’s working properly:
- Lock and unlock your car: Try locking and unlocking your Honda using the buttons on the key fob.
- Start the engine: If your key fob has a remote start feature, try starting the engine.
If your key fob still isn’t working after replacing the battery, the issue might be more complex than just a dead battery. In such cases, it’s best to consult your Honda dealership or a qualified automotive locksmith.
Tips and Considerations
- Don’t touch the battery terminals: Avoid touching the battery terminals with your fingers, as this can transfer oils and affect the battery life.
- Dispose of the old battery properly: Used batteries can be harmful to the environment. Make sure to dispose of the old battery at a designated battery recycling point.
- Consider professional programming: While replacing the battery yourself is usually straightforward, you may need to visit a battery key fob honda specialist or dealership if the key fob still doesn’t function correctly after the battery change. This might indicate a need for reprogramming.
