If you own an Infiniti vehicle equipped with an intelligent key system, you may encounter a frustrating situation where your key fob is not detected by the car, making it impossible to start the engine.
This issue, commonly known as “Infiniti Key ID Incorrect,” can be inconvenient, especially when you’re in a hurry or in a remote location.
In this comprehensive guide, we will explore the potential causes of this problem and provide you with eight effective ways to fix it.
How to Fix Incorrect Infiniti Key ID?
1. Replace Key Fob Battery
The key fob relies on a small lithium coin cell battery to power the transmitter and receiver, allowing communication with the car’s computer. Over time, the battery can lose its charge and become incapable of sending or receiving signals.
As a result, the car fails to recognize the key fob, leading to error messages like “No I-Key Detected” or “I-Key System Error” on the instrument cluster. To address this issue, simply replace the key fob battery.
To replace the battery, follow these steps:
- Locate the mechanical key inside the key fob and release it by sliding the lock knob on the back.
- Insert the mechanical key into the slot on the side of the key fob and gently pry it open.
- Remove the old battery from the holder and dispose of it properly.
- Insert a new CR2032 battery into the holder with the positive (+) side facing up.
- Snap the key fob back together and test it by pressing any button.
If replacing the battery does not resolve the problem, you may need to reprogram the key fob or investigate other potential issues.
2. Worn Buttons
The rubber buttons on the key fob can deteriorate over time due to frequent use and exposure to heat, moisture, dirt, or chemicals.
This deterioration can hinder their ability to make contact with the circuit board inside the key fob and transmit signals to the car. To fix this issue, consider replacing the worn buttons or the entire key fob shell.
Replacement buttons or shells can be purchased online or from a dealer. As a temporary fix, you can use a small piece of aluminum foil to cover the worn button and improve its conductivity.
However, this may not provide a reliable long-term solution.
3. Poor Battery Contact
The battery holder inside the key fob can loosen or corrode over time, resulting in a weak connection between the battery and the circuit board.
This weak connection can impact the power supply and signal transmission of the key fob. To address this issue, clean and tighten the battery holder.
Follow these steps to clean and tighten the battery holder:
- Open the key fob as described previously.
- Remove the battery and inspect it for signs of corrosion or damage. Replace it if necessary.
- Use a cotton swab dipped in rubbing alcohol to clean any dirt or corrosion from the battery holder and contacts.
- Gently bend or squeeze the metal tabs on the battery holder using a small screwdriver or pliers to ensure a snug fit with the battery.
- Reinsert the battery with the positive (+) side facing up.
- Close the key fob and test it by pressing any button.
If cleaning and tightening the battery holder does not solve the problem, you might need to replace the entire key fob or investigate other potential issues.
4. Water Damage
Water damage is another potential cause of key fob malfunction in Infiniti vehicles. The key fob is not waterproof and can be damaged by exposure to water, moisture, humidity, or liquids. This can lead to short circuits, corrosion, or oxidation on the circuit board or components inside the key fob.
To resolve this issue, it’s crucial to dry out the key fob as soon as possible.
Follow these steps to dry out the key fob:
- Open the key fob as described previously.
- Remove the battery and dispose of it properly.
- Gently blot any excess water or liquid from the key fob using a soft cloth or paper towel.
- Use a hairdryer on low heat or place the key fob in a bowl of uncooked rice or silica gel packets to absorb any remaining moisture. Avoid high heat or direct sunlight, as it can damage the key fob.
- Wait for at least 24 hours or until the key fob is completely dry.
- Insert a new battery with the positive (+) side facing up.
- Close the key fob and test it by pressing any button.
If drying out the key fob does not resolve the problem, you might need to replace the entire key fob or investigate other potential issues.
5. Defective Key Fob
A defective key fob can also cause issues with key recognition in Infiniti vehicles. Manufacturing defects, faulty components, or damaged circuit boards can prevent the key fob from functioning properly.
This leads to the car failing to recognize the key fob and displaying messages like “Incorrect Key ID” or “Invalid Key ID” on the instrument cluster.
If you suspect that your key fob is defective, you may need to replace it. Contact your local Infiniti dealer or a certified locksmith to obtain a new key fob and have it programmed to your vehicle.
6. Receiver Module Issues
The receiver module inside the car may experience issues that prevent it from properly detecting the signals from the key fob.
This can result in the “Infiniti Key ID Incorrect” problem. To diagnose and fix receiver module issues, it is recommended to take your vehicle to an authorized Infiniti service center.
They have the specialized equipment and expertise to diagnose and resolve these types of issues.
7. Signal Interference
Signal interference from external sources can disrupt the communication between the key fob and the car’s receiver module, leading to the “Infiniti Key ID Incorrect” problem.
Sources of signal interference can include nearby electronic devices, strong radio signals, or physical barriers between the key fob and the car.
To minimize signal interference, try the following:
- Keep your key fob away from other electronic devices, such as smartphones, tablets, or laptops.
- Avoid placing the key fob near metal objects or surfaces that can reflect or block the signals.
- Ensure that the key fob is within a reasonable range of the car when attempting to start it.
8. Dead 12 Volt Battery
In some cases, a dead or low 12-volt battery in your Infiniti vehicle can cause the “Infiniti Key ID Incorrect” problem.
A low battery voltage can affect the functioning of the key fob and prevent it from being recognized by the car. If you suspect that your car’s battery is the issue, have it tested and replaced if necessary.
