Is your Nissan Pathfinder key fob suddenly not working? Before you panic, the most likely culprit is a dead battery. Replacing the battery in your key fob is a simple and cost-effective fix you can do yourself. This guide will tell you everything you need to know about the Nissan Pathfinder Key Fob Battery Size and how to replace it.
Typically, Nissan Pathfinder key fobs are powered by one of these batteries: CR2032, CR2025, CR2016, or sometimes a 23A 12V battery. To be absolutely sure which battery your specific Nissan Pathfinder key fob requires, the best approach is to check your owner’s manual or, even easier, to open your key fob and take a look at the old battery before you head out to buy a replacement. These batteries are commonly available online and at most stores that sell batteries, and they usually cost under $6.
Replacing your Nissan Pathfinder key fob battery is straightforward. Here’s a step-by-step guide:
-
Open the Key Fob: For newer Nissan Pathfinder models, you’ll usually find a hidden key inside the fob. Locate the small release button or latch, and remove the mechanical key. This will often reveal a slot where you can insert the key (or a small flathead screwdriver) to gently pry the two halves of the key fob casing apart. For older models, inspect the sides of the key fob for a small notch. Use a thin, flat object like a screwdriver or even a coin in this notch to carefully pry the case open.
-
Access the Battery: Once open, carefully lift the circuit board inside. The battery is usually located underneath. Pay close attention to the orientation of the battery before removing it – note which side is facing up so you insert the new one correctly.
-
Replace the Battery: Remove the old battery and replace it with a new battery of the correct size. Ensure the positive (+) side of the battery is facing the correct way, matching the original battery’s placement.
-
Close and Test: Carefully snap the key fob case back together until it’s securely closed. Now, test your key fob by pressing the buttons to lock or unlock your Nissan Pathfinder. If it doesn’t work immediately, double-check that the battery is correctly oriented and making good contact with the terminals. Clean the contacts if necessary.
Understanding the type of key fob you have can also be helpful:
- Standard Remotes: Basic remotes with lock, unlock, and sometimes panic buttons.
- Flip Keys: Keys that have a blade that flips out from the remote body.
- Remote Heads: Keys where the key blade is permanently attached to the remote.
- Fobik Keys: Key fobs where the key is separate and inserted into the ignition, often hiding within the fob.
- Smart Keys: Used for push-to-start systems and offer features like proximity unlocking.
If replacing the battery doesn’t solve the problem with your Nissan Pathfinder key fob, the issue might be more complex. In this case, you might need to consider a full key fob replacement or seek professional assistance from a locksmith or dealership.
