How to Replace the Renault Kadjar Key Fob Battery?
Replacing the Renault Kadjar key fob battery is a simple process that involves sliding off the key cover, removing the old CR2032 battery, and inserting a new one. With just a small flathead screwdriver and a new battery, you can restore your key fob’s functionality in minutes.
How Do You Open the Renault Kadjar Key Fob to Access the Battery?
To open the Renault Kadjar key fob, start by locating the small indentation or seam on the back of the key. Slide the plastic cover gently in the indicated direction—usually downwards or sideways—without forcing it. This reveals the internal compartment and the emergency key blade. Use a small flathead screwdriver if needed to carefully pry open the battery compartment cover.
What Type of Battery Does the Renault Kadjar Key Fob Use?
The Renault Kadjar key fob uses a CR2032 lithium coin battery, a popular and reliable type known for its long life and stable voltage. This battery is widely available and affordable, making it easy to find replacements. Using a high-quality battery, such as those from RackBattery, can ensure longer-lasting performance.
How Do You Remove the Old Battery from the Renault Kadjar Key Fob?
Once the battery compartment is open, use a small flathead screwdriver or your fingernail to gently lift the old battery out of its slot. Take note of the battery’s orientation—usually with the positive side facing up—so you can insert the new battery correctly. Avoid touching the battery contacts directly to prevent corrosion or damage.
How Should You Insert the New Battery into the Renault Kadjar Key Fob?
Insert the new CR2032 battery into the slot with the positive side facing up, matching the orientation of the old battery. Slide it under any retaining clips or tabs to secure it in place. Make sure the battery sits flush and firmly within the compartment to ensure proper contact and functionality.
How Do You Reassemble the Renault Kadjar Key Fob After Battery Replacement?
After inserting the new battery, replace the battery cover by snapping it back into place. Then slide the outer key fob cover back on until it clicks securely. Test the key fob by pressing the buttons to confirm it is working correctly. If the key fob does not respond, double-check the battery orientation and ensure all covers are properly closed.
