The Qashqai has a distinct SUV feel to it thanks to its bigger dimensions, and the ride on 19-inch wheels in Ti and ST-L models may be firm at times. The front tyres of the Qashqai can lose grip on rough surfaces, and its CVT may occasionally exhibit wrist-flexing torque steer.
It is usually due to the battery being dead, which can be replaced in a matter of minutes. Make sure that the replacement battery is the same voltage, size and specifications.
Water Damage
Water damage is among the most common causes that cause an Nissan keyfob to display the "key ID wrong" message. The rubber seals on the key fob are designed to protect the chip's electronic circuit, but prolonged exposure to moisture could cause it not to work correctly. It's normal to see this when your key fob was dropped in the water or in a swimming pool. However, it can occur when it's wet due to rain or soapy hand.
If your key fob has been exposed to water for many years, you may need to clean it using isopropyl and electronic cleaner. It may also need to be taken to a specialist for repair or replacement.
If your key fob does require replacement the process is simple. Make sure you have the right multipack (CR2032 3V). Then open the front and back cases with the small flathead screwdriver. You'll need to take out the retaining clips made of metal and then push out the battery that was in place, and then replace it with the new one. After reassembling the fob put the mechanical key back in position and ensure that it is working correctly. If it does not, you'll need to take it to a Nissan dealer or professional auto locksmith for the replacement of the chip in the key. The chip is usually not damaged by water and isn't too costly.
Dead Coin Battery
Another common reason the reason your Nissan Qashqai key fob may not function is that the battery inside is dead. These batteries last for three to five years, but can become faulty over time when the fob is dropped frequently. You could replace the battery but make sure it is the same voltage and same size as the first. If you install a new battery, it could cause the key to be assigned a wrong key ID. This can prevent it from being connected to your vehicle.
The most effective method of changing the coin battery in a Nissan Qashqai Key Fob is to pry it open using an small screwdriver that has a flat head. Push in the screwdriver in tiny notch at the bottom of the fob, and move it around to separate the two parts of the key fob. Remove the old CR2025 battery and replace it with a brand new one, observing the position of the old one within the fob.
Before putting the new battery into place be sure that there is no dirt or water damage to the terminals. If there is, clean the terminals using a small amount of isopropyl alcohol. You should also ensure that the pole cables are connected correctly. They should be connected to the positive and negative poles of the battery respectively.
Diagnostics of a fault
If your Nissan Qashqai's main fob stops functioning after being exposed to pure rainwater or clean tap water it could indicate that there's a problem with the internal chip. The battery replacement won't fix this, and you'll have to buy another key fob. If the key fob didn't work after dropping 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 in.
A common error that you may notice on the dashboard of your vehicle is "Key ID Not Correct." The vehicle is unable recognize the key fob and consequently, won't allow the vehicle to start. The problem can be caused by a variety of factors such as water damage, undetectable faults in the key fob's circuitry, or RFID interference.
The key fob will stop working if the 12 volt batteries are dead or fail to provide enough electric current. This can affect your Nissan Qashqai's keyless system central locking, as well as the ability to start the engine with the key fob. If you're unable unlock or lock the door manually it is recommended to check the batteries inside the key fob to make sure they're in good shape. You may also try reinstalling the battery to reset your transmitter.
Reprogramming
If the key fob was not submerged in saltwater it should return to life by a simple wash of clean water. You can 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 with a new one.
If your Nissan Intelligent Key is still not working, it could be an issue with the connection between it and your car. To reconnect it, start by turning the key in the ignition, without turning on the car. Continue to do this until you see the danger lights flash twice. Then, turn off your vehicle and remove the key.
Then, you need to then open the fob compartment in your vehicle. It's usually located in the door jamb, on the handle for the driver's door or under the armrest. Find the small "program" button and press it. You should hear a chime after the process has been completed.
Now that your Intelligent Key is relinked to the car now is the time to try it out. Stand some distance away from the car, and hit all the buttons on the key. If the lights flash, or the horn sounds, then the key is successfully connected to the Nissan. You can also try testing it in close proximity.
