Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai's larger dimensions give it an SUV feel. Its ride on 19-inch alloy wheels on Ti and STL versions may also be a bit firm. The front tyres may lose grip on rough surfaces, and its CVT might occasionally exhibit wrist-flexing torque steer.
This is usually caused by a dead battery, which can be replaced in a matter of minutes. Make sure the replacement battery has the same size, voltage and specifications.
Water Damage
One of the main reasons a Nissan key fob might display the "key ID is not correct" message is due to water damage. The rubber seals on the key fob shield the chip's electronics, but prolonged exposure to moisture can cause it to malfunction correctly. It is common to observe this if your key fob was dropped in the water or in a swimming pool. However, it could also happen when it gets wet due to the rain or soapy hands.
If your key fob was exposed to water over the course of a long time and you're not sure, clean it with isopropyl, or an electronic cleaner. Alternatively, it might need to be taken to a specialist to repair or replace it.
If your key fob needs to be replaced, it is quite simple to do. Make sure you have the correct multipack (CR2032 3V). Then open the front and back cases with an abrasive screwdriver. Remove the metal clips, then remove the old battery and then replace it. After reassembling the fob, put the mechanical key back in position and ensure that it functions as intended. If it isn't, you'll need to take it to an Nissan dealer or professional auto locksmith for the replacement of the chip in the key. Fortunately, the chip is not often damaged by water exposure, so this should not cost you a lot.
Dead Coin Battery
The coin battery is a second frequent reason why your Nissan Qashqai remote key fob may not work. They typically last for 3 to 5 years, but they can become depleted over time, particularly if the fob is frequently dropped. You can replace the battery but be sure to use the same voltage and the same dimensions as the original. If you choose to use a different battery, it can cause the key to have an incorrect key ID that could hinder it from paired with your vehicle.
The best way to replace the battery of a coin on a Nissan Qashqai key fob is by opening the key fob using an small screwdriver that has a flat head. The screwdriver should be inserted into a small notch at the bottom of the key fob. Simply twist the screwdriver to divide the two halves. Then, remove the old CR2025 button cell battery and insert another one after confirming its position on the fob.
Examine the terminals to see if there is dirt or water damage prior to installing the new battery. If there is, clean the terminals using the smallest amount of isopropylethanol. Make sure that the pole cables are properly connected. They should be connected to the negative and the positive poles of your battery.
Diagnostics of a fault
If your Nissan Qashqai key fob stops working after exposure to clean rain or tap water, it may be a sign of an internal chip issue. Change nissan car keys won't fix this, and you'll need to buy a new key fob. If the key fob stopped working after you dropped it, it's likely that the chip inside was damaged. It is usually possible to get the key fob back to function again if you take it out and clean the chip with paper towel and isopropyl alcohol and then insert it back into.
Key ID Incorrect is a typical mistake that you might see on the dashboard of your car. The vehicle is not able to recognize the key fob and thus won't allow the vehicle to start. The issue can be caused by several things such as water damage, undetectable faults in the circuitry of the key fob, or RFID interference.
If the 12 volt battery in your key fob is broken or is not supplying enough electric current, it will stop working. This can affect the remote keyless system as well as central locking of your Nissan Qashqai, as well as preventing you from starting the engine with the key fob (if equipped with Intelligent Key). Check the batteries inside the key fob if you are in a position to lock or unlock your door by hand. You could also try replacing the battery to reset your transmitter.
Reprogramming
If the key fob was not submerged in saltwater it should be restored to its original state with a simple wash of clean water. You could also try cleaning the electronic chip using isopropyl Alcohol or an electronic cleaner. If these methods don't work it could be time to replace the entire key fob by a new one.
If your Nissan Intelligent Key still does not work, there could be a connection problem between it and your vehicle. To reconnect it, begin by turning the key into the ignition but without starting the car. Continue this process until you see the danger lights flash twice. Then, turn off the vehicle and remove the key.
Open the fob compartment of your vehicle's fob compartment. It's usually in a door jamb, on the handle for the driver's door or under an armrest. Find the small "program" button and press it. When the process is complete, you should hear an audible sound.
Now that your Intelligent Key is relinked to the car is the time to test it out. Set your feet a distance from the vehicle, and press all the buttons on it. If the lights flash, or the horn sounds, the key is successfully connected to the Nissan. You can also test it near the Nissan.
