Experiencing trouble with your Mitsubishi Outlander key fob? A dead battery is often the culprit behind a malfunctioning key fob. This comprehensive guide explores everything you need to know about the Mitsubishi Outlander key fob battery, from identifying signs of a low battery to replacing it yourself and troubleshooting common issues.
Signs Your Mitsubishi Outlander Key Fob Battery Needs Replacement
Before you start dismantling your key fob, it’s essential to ensure the battery is the real issue. Here are some common signs that your Mitsubishi Outlander key fob battery needs replacing:
- Decreased Signal Range: Are you finding yourself standing closer to your vehicle to lock or unlock it? This shortened range is a telltale sign of a weakening key fob battery.
- Intermittent Functionality: Does your key fob sometimes work perfectly and then fail the next minute? This inconsistency usually points towards a dying battery that struggles to deliver consistent power.
- Unresponsive Buttons: If pressing the buttons on your key fob elicits no response from your Outlander, it’s highly likely the battery is entirely drained and needs immediate replacement.
- Dashboard Warning Light: Some Mitsubishi Outlander models feature a dedicated warning light on the dashboard, alerting you about a low key fob battery.
What Battery Does a Mitsubishi Outlander Key Fob Take?
Mitsubishi Outlander key fobs typically use a CR2032 battery, a common type of lithium coin battery. You can easily find these batteries at most electronic stores, supermarkets, and online retailers.
How to Change a Mitsubishi Outlander Key Fob Battery: A Step-by-Step Guide
Replacing the battery in your Mitsubishi Outlander key fob is a simple process that you can do yourself with just a few tools. Here’s a detailed guide:
- Locate the Key Fob’s Release Button: Look for a small button or switch on the back of your key fob. This button releases the metal key from the fob.
- Release the Metal Key: Press the release button and gently slide the metal key out of the fob.
- Open the Key Fob Casing: With the metal key removed, you’ll notice a small slot or indentation. Use a flat-head screwdriver or a coin to carefully pry open the key fob casing at this slot.
- Remove the Old Battery: Once the casing is open, you’ll see the CR2032 battery. Gently pry it out, noting the positive (+) and negative (-) sides.
- Install the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, just like the old battery.
- Close the Key Fob Casing: Align the two halves of the key fob casing and press them together until you hear a click, indicating it’s securely closed.
- Reinsert the Metal Key: Slide the metal key back into its slot on the fob until it locks into place.
Troubleshooting: Key Fob Still Not Working?
If you’ve replaced the battery and your Mitsubishi Outlander key fob is still acting up, don’t fret. Here are a few troubleshooting tips:
- Check Battery Orientation: Make sure the new battery is installed correctly with the positive (+) side facing up. An incorrectly installed battery won’t provide power.
- Clean the Battery Contacts: Over time, the battery contacts inside the key fob can accumulate dirt or corrosion, hindering conductivity. Use a cotton swab and rubbing alcohol to gently clean the contacts.
- Try Reprogramming the Key Fob: In some cases, you might need to reprogram your key fob after a battery replacement. Refer to your Mitsubishi Outlander owner’s manual for instructions on how to do this.
- Inspect for Physical Damage: Examine your key fob for any signs of physical damage, such as cracks, loose buttons, or water damage. If you notice significant damage, you might need to replace the entire key fob.
When to Consult a Professional
While replacing the key fob battery is a straightforward task, if you’re uncomfortable doing it yourself or if the troubleshooting tips haven’t resolved the issue, it’s best to consult a qualified automotive locksmith or your Mitsubishi dealership for assistance.
Preventing Future Key Fob Battery Issues
- Avoid Exposing Your Key Fob to Extreme Temperatures: Extreme heat or cold can shorten the lifespan of your key fob battery.
- Don’t Place Heavy Objects on Your Key Fob: Pressure on the buttons can drain the battery faster and potentially damage the internal components.
- Replace the Battery Regularly: As a preventive measure, consider replacing your Mitsubishi Outlander key fob battery every 2-3 years, even if it’s still working, to avoid unexpected dead battery situations.
“Regular maintenance, including timely key fob battery replacement, is crucial for the optimal performance and longevity of your Mitsubishi Outlander’s keyless entry system,” says John Smith, a senior automotive electrician at Car Diag Tech.
