How To Replace the INFINITI Key Fob Battery

A functioning key fob makes accessing and operating your INFINITI vehicle simple and convenient. When your key fob battery begins to fail, features such as remote start and keyless entry become unreliable or stop working altogether. The INFINITI key fob battery replacement is a straightforward process that you can handle yourself. Although key fob batteries typically last between three and five years before needing replacement, this varies according to the frequency of use and environmental conditions.

Signs Your Key Fob Battery Is Low

Several indicators can help you identify when your INFINITI key fob battery needs replacement. If your key fob isn’t responding consistently when pressing the lock or unlock buttons, it can be a sign of a weakening battery. You may have to stand closer to your vehicle for the remote functions to work since the operating range decreases with battery power. The LED light on your key fob may appear dim or stop functioning completely, and you may see a dashboard warning light indicating low battery power.

If you have a vehicle equipped with an Intelligent Key system, you may notice that the doors don’t unlock automatically when you approach your vehicle. This can happen if the Intelligent Key battery is low or if you’re holding the key too close to the door handle sensor. When the distance between the Intelligent Key and the door handle is too short, the system will have difficulty recognizing the fob.

Your dashboard may display a warning light indicating low key fob battery power, and push-button start systems may begin to malfunction. Since these symptoms can vary depending on your specific INFINITI model, you should consult your owner’s manual for model-specific information about low battery indicators.

Where To Purchase Replacement Batteries

INFINITI key fobs use two main types of batteries: CR2025 for standard key fobs and CR2032 for Intelligent Key fobs. Check your owner’s manual to verify the correct battery type for your specific model. Auto parts stores and electronics shops typically stock both battery types. Many general retailers and online marketplaces, such as Walmart and Amazon. No specialized service center is required for battery replacement, meaning you can easily do this yourself. While you can purchase these batteries from any reputable seller, buying from your local INFINITI dealership guarantees compatibility with your specific key fob model.

Step-By-Step Guide to Replacing Your INFINITI Key Fob Battery

You should replace your INFINITI key fob battery carefully to avoid damaging the internal components. Begin by locating the release tab on the back of your key fob. Take out the metal car key first, then carefully remove the protective panel. If necessary, use a flathead screwdriver wrapped in tape to avoid scratching the fob’s surface. Once you’ve accessed the battery compartment, take note of how the old battery is positioned. Remove it carefully and insert the new battery in the same position, with the positive side facing down.

Reassemble the key fob by reattaching the panel and reinserting the metal key. Test your key fob’s functionality by pressing the lock and unlock buttons while standing near your vehicle. All features should work properly, including remote start if your model includes this feature. If you experience any issues, double-check that the battery is properly seated and oriented.

Starting Your INFINITI Without a Working Key Fob

If your key fob battery dies completely, you can still access and start your INFINITI using alternative methods. For most models, you’ll find a hidden mechanical key within the fob that allows you to unlock the door manually. Starting procedures vary by model, but INFINITI has engineered backup methods to ensure you’re not stranded.

Q60 Convertible, Q60 Coupe, QX50, and QX70 owners can use the key port insertion method. Simply locate the port in the lower left dash panel, insert your key fob, and press the ignition button to start the engine.

For Q50, QX60, and QX80 models, use the direct ignition button contact method. Hold your Intelligent Key against the start button until you hear a chime. Within 10 seconds, press the start button while holding down the brake pedal. You may need to try this process multiple times before the engine starts.
