How To Start Infiniti With Dead Key Fob

A key fob is an essential component of modern vehicle operation, providing convenient access and ignition capabilities. However, a dead or malfunctioning key fob battery can leave you stranded. Fortunately, Infiniti vehicles are equipped with a system to bypass a dead fob and start the engine. This article outlines the process of starting your Infiniti with a dead key fob.

Locate the Emergency Key

Most Infiniti key fobs contain a physical, mechanical key, often referred to as an emergency key or valet key. This key allows you to manually unlock the vehicle.

1. Examine your key fob for a release mechanism. This is usually a small button or slider.
2. Press or slide the release mechanism.
3. Pull the emergency key out of the fob.

This key will resemble a traditional metal key and will have the ability to unlock the driver's side door.

Unlock the Vehicle Manually

Using the emergency key, manually unlock the driver’s side door.

1. Insert the emergency key into the driver’s side door lock.
2. Turn the key clockwise to unlock the door. You might need to apply slight pressure if the lock hasn't been used manually in a while.
3. Open the door. The alarm may sound upon entry, but it will cease once the engine is started.

Identify the Key Fob Port or Designated Area

Infiniti vehicles generally utilize one of two methods for starting the vehicle with a dead key fob: a dedicated key fob port or a designated area.

Key Fob Port

Some Infiniti models feature a specific port designed to receive the key fob. This port is commonly located in the steering column or the center console.

1. Look for a slot or receptacle that appears to be designed for the key fob. Consult your owner’s manual for the precise location if you are unsure.
2. Insert the entire key fob into the designated port. Ensure it is fully seated.

Designated Area (Start/Stop Button Method)

Other Infiniti models employ a designated area, usually near the start/stop button, where the key fob needs to be placed to initiate engine starting.

1. Locate the start/stop button.
2. Identify the designated area. This may be indicated by a small key fob symbol or a marking in the immediate vicinity of the start/stop button. Consult your owner's manual for clarification.
3. Hold the key fob directly against the start/stop button or the designated area.

Start the Engine

With the key fob correctly positioned in the key fob port or held against the designated area, you can now start the engine.

Key Fob Port Method

1. Ensure the key fob is fully inserted into the port.
2. Depress the brake pedal completely.
3. Press the start/stop button. The engine should start.

Designated Area (Start/Stop Button Method)

1. Ensure the key fob is held firmly against the start/stop button or the designated area.
2. Depress the brake pedal completely.
3. Press the start/stop button. The engine should start. You might need to hold the key fob in place while pressing the button.

Troubleshooting

If the engine fails to start after following these steps, consider the following troubleshooting measures:

• Verify Key Fob Placement: Ensure the key fob is correctly inserted into the port or is positioned properly against the start/stop button/designated area.
• Check Battery Voltage: Although the intention is to bypass the dead battery, a severely depleted vehicle battery can sometimes interfere with the starting process. Verify that your car battery has sufficient voltage.
• Consult the Owner's Manual: Refer to your vehicle's owner's manual for specific instructions and diagrams related to starting your Infiniti with a dead key fob.
• Contact Infiniti Roadside Assistance: If you are still unable to start the vehicle, contact Infiniti roadside assistance for professional support.

Replacing the Key Fob Battery

Once you have successfully started your vehicle using the emergency method, it is imperative to replace the key fob battery as soon as possible.

1. Identify the battery type. Consult your owner's manual or examine the existing battery to determine the correct replacement. Common types include CR2032 and CR2025.
2. Open the key fob casing. This typically involves using a small screwdriver or similar tool to pry open the casing along a seam.
3. Remove the old battery and install the new battery, ensuring correct polarity (+ and -).
4. Reassemble the key fob casing securely.
5. Test the key fob functionality by attempting to unlock and lock the doors remotely.

Note: Some Infiniti models might require reprogramming the key fob after battery replacement. If the remote functions do not work after replacing the battery, consult your owner's manual or a qualified Infiniti technician for reprogramming instructions.

Practical Advice and Insights

Preventative Measures: To avoid the inconvenience of a dead key fob battery, consider replacing the battery every one to two years, even if it is still functioning. This is a relatively inexpensive preventative measure.

Carry a Spare Battery: Keep a spare key fob battery in your glove compartment or purse for emergencies.

Familiarize Yourself: Take the time to familiarize yourself with the location of the emergency key, the key fob port/designated area, and the battery replacement procedure for your specific Infiniti model.

Key Fob Protection: Consider purchasing a key fob protector to prevent damage from drops or impacts, which can shorten battery life or damage the fob's internal components.

Understanding the process of starting your Infiniti with a dead key fob provides a valuable contingency plan. By following these steps, you can regain control of your vehicle and avoid being stranded in an emergency situation. Furthermore, proactively maintaining your key fob and replacing the battery regularly will minimize the likelihood of encountering this issue.
