Is your 2007 Honda CRV key fob not working as reliably as it used to? You might be facing a dead battery. The good news is, replacing the battery in your Honda CRV key fob is a straightforward task you can easily handle yourself, saving you time and money compared to a dealership visit. This guide will walk you through the process step-by-step.
Identifying the Right Battery: CR1616
The 2007 Honda CRV key fob uses a CR1616 battery. This 3V lithium battery, while not as common as AA or AAA batteries, is readily available at most drugstores, electronics stores, and online retailers. You can find brands like Energizer or Duracell. While some stores like Walmart or CVS pharmacy might carry them, you might have better luck at stores like Walgreens or dedicated battery suppliers. Purchasing batteries online can sometimes offer cost savings, especially if you buy in bulk or find deals.
Step-by-Step Honda CRV Key Fob Battery Replacement
Replacing the battery is a simple process that requires minimal tools and time. Here’s how to do it:
Tools You’ll Need
- A small Phillips head screwdriver (mini or micro size)
- A new CR1616 battery
- A soft cloth (like terrycloth) to protect the key fob
Opening the Key Fob Casing
- Locate the Screw: On the back of your Honda CRV key fob, you’ll find a small Phillips head screw.
- Unscrew Carefully: This screw can be a bit tight, possibly due to threadlocker applied at the factory. Use the mini Phillips screwdriver and apply firm, steady pressure while turning counterclockwise. It might be helpful to use pliers or a vice-grip to get a better grip on the screwdriver for initial loosening, but be careful not to damage the screw head. Placing the key fob on a soft cloth can prevent scratches.
- Separate the Key Fob Halves: Once the screw is removed, gently pry open the two halves of the key fob casing. They should separate easily.
Accessing and Replacing the Battery
- Open the Inner Cassette: Inside the key fob, you’ll see a black plastic inner cassette containing the electronics. This cassette also splits into two halves. Carefully pry this open as well.
- Locate the Battery: The CR1616 battery will be visible inside the cassette.
- Remove the Old Battery: Gently remove the old battery. Note the orientation of the battery – usually, the positive (+) side with writing faces down, hidden from view when installed.
- Install the New Battery: Take your new CR1616 battery and place it into the slot. Use a cloth to press it into place, avoiding touching the battery contacts directly with your fingers. Ensure the positive (+) side is facing down, matching the original orientation.
Reassembling the Key Fob
- Close the Inner Cassette: Snap the two halves of the inner cassette back together.
- Rejoin the Key Fob Halves: Align the two halves of the key fob casing and press them firmly together until they snap shut.
- Reinstall the Screw: Replace the Phillips head screw and tighten it securely, but don’t overtighten.
Tips for a Smooth Battery Replacement
- Stubborn Screw: If the screw is very difficult to remove, ensure you are using the correct size Phillips head screwdriver and applying firm, direct pressure.
- Battery Orientation: Double-check the orientation of the old battery before removing it and install the new one in the same way.
- Clean Hands: While not critical, using clean hands or gloves can prevent transferring oils to the battery or electronic components.
Cost Savings of DIY Battery Replacement
Dealerships often charge inflated prices for simple services like key fob battery replacement, sometimes quoting around $15 or more. By purchasing a CR1616 battery for around $5 and doing it yourself, you can save a significant amount of money and gain the satisfaction of handling simple car maintenance tasks yourself.
Replacing your 2007 Honda CRV key fob battery is an easy and economical DIY task. By following these steps, you can quickly restore the functionality of your key fob and avoid unnecessary dealership costs.
