How to Start Your INFINITI With a Dead Key Fob

Your INFINITI key fob is an important component of your vehicle’s advanced security and convenience system. It uses a small internal battery, which transmits a signal to your vehicle’s onboard computer so that you can lock and unlock the doors remotely, start the engine, and access various vehicle features without physically inserting a key.

However, the battery in the key fob can deplete over time, rendering it temporarily useless until replaced. Other reasons your key fob may stop working include signal interference or internal component failure. Fortunately, even if the battery is dead, there are alternative methods you can use to start your INFINITI vehicle. Read on to discover the steps to take when your key fob fails.

How To Start Your INFINITI Without a Key Fob

INFINITI vehicles have backup systems to ensure you can still operate your car, even if your key fob’s battery dies. Below, we’ve listed some of the methods you can use in such a situation.

Use the Key Fob’s Built-in Mechanical Key

Most INFINITI key fobs come with a hidden mechanical key inside. To access it, locate the small release latch on the back of your key fob. Slide or press the latch to release the hidden key, then use the mechanical key to manually unlock the driver’s side door. Once inside, you can start the car without the electronic signal from your key fob.

Start Your INFINITI Using the Key Fob

Even if its battery is dead, your INFINITI key fob can still communicate with the vehicle. Here are some steps to start your car without the key fob:

• Press the brake pedal firmly (for automatic transmissions) or depress the clutch (for manual transmissions).
• Hold the key fob against the push-start button.
• Press the start button while holding the fob in place.

This method works because the vehicle’s proximity sensors can still detect the embedded RFID chip in the key fob, allowing the engine to start smoothly.

Replace the Key Fob Battery

If you need to replace the battery in your key fob, just follow these instructions:

• Open the key fob by using the release mechanism to separate the two halves.
• Remove the old battery, which is usually a CR2032 or CR2025 coin battery.
• Insert the new battery, ensuring the correct polarity.
• Reassemble the key fob and test it to make sure everything’s working as it should.

Use INFINITI’s Key Fob App (If Available)
