Understanding Your Nissan Qashqai Key Fob
Before diving into the steps, it’s essential to understand the structure of your Nissan Qashqai’s key fob. The key fob typically consists of a few key components: the exterior casing, the key blade, the battery compartment, and the electronic circuit board**. The key blade is the physical key used to unlock your car manually, while the electronic circuit board houses the circuitry that allows the key fob to communicate with your car’s immobilizer system.
The battery compartment is usually located on the back of the key fob and is secured with a small screw or a snap-on cover. Inside this compartment, you’ll find a small, coin-cell battery, typically a CR2032 model, which powers the key fob’s electronics.
Gathering the Necessary Tools and Materials
Before you begin, make sure you have the following tools and materials on hand:
- A small Phillips head screwdriver
- A new CR2032 battery
- A small piece of cloth or a soft-bristled brush (optional)
Having these items readily available will ensure a smooth and efficient process.

Step 1: Open the Battery Compartment
Locate the small screw or snap-on cover on the back of your key fob. Using the Phillips head screwdriver, carefully remove the screw if present. If it’s a snap-on cover, gently pry it open using your fingernails or a small, flat-head screwdriver.
Step 2: Remove the Old Battery
Once the battery compartment is open, you’ll see the old battery. Gently lift it out using your fingers or a small tool. Be careful not to touch the metal contacts on the battery as this can damage the circuit board.
Step 3: Insert the New Battery
Align the new CR2032 battery with the positive (+) and negative (-) terminals in the battery compartment. Ensure the battery is properly seated and making contact with the terminals.
Step 4: Close the Battery Compartment
Carefully snap the cover back into place or replace the screw. Make sure the compartment is securely closed to prevent the battery from falling out or getting damaged.
Step 5: Test the Key Fob
Press the buttons on your key fob to ensure the new battery is working correctly. If the buttons respond as expected, congratulations! You’ve successfully changed the battery in your Nissan Qashqai key fob.

- Key Fob Not Responding: If your key fob still doesn’t respond after replacing the battery, check the battery contacts for any dirt or debris. Gently clean them with a soft cloth or a soft-bristled brush. If the problem persists, the key fob’s electronic circuit board might be faulty and require professional repair.
