10 Key Factors About Nissan Qashqai Key Fob You Didn't Learn In School
Reasons Why Your Nissan Qashqai Key Fob Won't Work

The Qashqai's larger dimensions give it an SUV-like feel. Its ride on 19-inch alloy wheels in Ti and STL models can also be a bit firm. The front tyres of the Qashqai can lose grip on rough surfaces and its CVT may occasionally exhibit wrist-flexing torque steer.

This is usually caused by a dead battery that can be replaced in a matter of minutes. Make sure the replacement battery is of the same size, voltage and specifications.

Water Damage

Water damage is among the most common reasons for an Nissan keyfob to display the "key ID wrong" message. The rubber seals on the key fob shield the chip's electronics, but long-term exposure to moisture can cause it to not function properly. It is common to observe this if your keyfob was dropped into the ocean or swimming pool. However, it can occur when it is wet due to showers or soapy hands.

If your key fob was exposed to water over a long period of time and you're not sure, clean it using isopropyl and electronic cleaner. Alternatively, it might require a visit to a specialist to repair or replace it.

If your key fob need to be replaced the process is simple. First, ensure that you have a multipack of the right battery (CR2032 3V). Unlock the front and rear cases using the flat-head screwdriver. You'll need to take out the clips for retaining metal and push out the old battery and put in the new one. Reassemble the fob and replace the mechanical key. Check to see if it functions properly. If it isn't it is necessary to go to your local Nissan dealer or an expert auto locksmith to replace the chip in the key. Fortunately, the chip is not often damaged by water exposure which means that this shouldn't cost you a lot.

Dead Coin Battery

Another reason that the reason your Nissan Qashqai key fob might not work is that the battery in the coin has gone dead. The batteries typically last for 3-5 years, but they are susceptible to becoming depleted over time, especially when the fob is frequently dropped. You could try replacing the battery with a fresh one, but make sure it's the same voltage and size as the original. If you are using another battery, it may cause the key to have an incorrect key ID which will prevent it from paired with your vehicle.

The best method to replace the coin battery on the Nissan Qashqai key fob is by opening the key fob using an small screwdriver that has a flat head. Insert the screwdriver into an angled notch on the bottom of the fob, and twist gently to separate the two halves of the key fob. Then, remove the old CR2025 button cell battery and replace it with another one after confirming its position in the fob.

Before you put the new battery in place ensure that there is no dirt or water damage to the terminals. If so clean the terminals using a small amount isopropyl ethanol. Make sure that the pole cables are properly connected. They should be connected both the positive and negative poles of your battery.

Diagnostics of a fault

If your Nissan Qashqai's keys fob doesn't function after being exposed to clean water from the tap or rain it could indicate that there is a problem with the internal chip. You'll require a new keyfob if you can't solve the issue by changing the battery. If the key fob has stopped working after you dropped it, it's likely that the chip inside was damaged. If you clean the chip with isopropylethanol and paper towels and then replace it with the key fob, you'll generally get it working.

Key ID Incorrect is a common mistake that you might see on the dashboard of your vehicle. G28CarKeys means that the vehicle cannot recognize the key fob and will not allow it to start the engine. This can happen in many different ways, including water damage, problems that are undetectable within the key fob circuitry or RFID interference.

If the battery that powers 12 volts in your key fob is dead or not providing enough electrical current it will cease to function. This will affect the remote keyless system as well as central locking on your Nissan Qashqai, as well as stopping you from starting the engine using the key fob (if equipped with Intelligent Key). If you're unable unlock or lock the door by hand, you should check the batteries in your key fob to make sure they are in good shape. You could also try reinstalling the battery to reset your transmitter.

Reprogramming

If the key fob has not been submerged in salt water the key fob should be able to return to life after a quick wash with clean water. You might also try cleaning your electronic chip with isopropyl alcohol or an electronic cleaner. If these don't work it could be time to replace the entire key fob with a brand new one.

If your Nissan Intelligent Key is still not working, there could be a problem with the connection between it and your car. To reconnect it, start by turning the key into the ignition, but not starting the car. Keep doing this until you see the hazard lights flash twice. Turn the vehicle off and take out the keys.

Open the fob compartment in your vehicle. It's usually found on the door jamb or the handle of the driver's door. Locate the small button labeled "program" and press it. Once the process has been completed, you should hear a chime.


It's time to put your Intelligent Key to the test. You must stand a certain distance away from the vehicle, and click all of the buttons on the key. If the lights flash, or the horn sounds, then the key is connected to the Nissan. You can also test it close to the Nissan.
