Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai's larger dimensions give it an SUV feel. Its 19-inch alloy wheels on Ti and STL models may also be firm. Its front tyres can also lose grip on rough surfaces and its CVT could occasionally exhibit wrist-flexing torque steer.
This is usually due to an unresponsive coin battery that is easily replaced in a matter of minutes. Make sure the battery you replace is of the same size, voltage and specification.
Water Damage
Water damage is among the most common reasons for a Nissan keyfob to display the "key ID is incorrect" message. The rubber seals on the key fob are designed to protect the chip's electronic components, however long-term exposure to moisture can cause it to not function properly. It's common to see this if your key fob has been dropped into the ocean or swimming pool. But it can also occur when it's wet due to rain or soapy hand.
If your key fob has been exposed to water for a prolonged duration, it might have to be cleaned with isopropyl alcohol or electronic cleaner. It may also need to be sent to a professional to repair or replace it.
If your key fob does need to be replaced, the procedure is relatively simple. First, ensure that you have a multipack of the correct battery (CR2032 3V). Remove the front and back cases using a flathead screwdriver. You'll need to take out the clips for retaining metal and remove the old battery and put in the new one. After reassembling the fob put the mechanical key back into place and verify that it operates correctly. If it does not it is necessary to bring it to a local Nissan dealer or an experienced auto locksmith to replace the chip on the key. Fortunately, the chip is not usually damaged by water exposure, so this should not be too expensive.
nissan spare key is a second common reason for why your Nissan Qashqai remote key fob might not work. These batteries last for 3-5 years, but they are prone to failure over time when the fob is dropped frequently. You can replace the battery, but be sure to use the same voltage and same size as the previous. If you install a new battery, it may cause the key to be assigned an incorrect key ID. This can prevent it from being paired with your vehicle.
The best way to change the coin battery in a Nissan Qashqai Key Fob is to pry it open with an small screwdriver that has a flat head. The screwdriver should be inserted into a small 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, noting the position of the old one in the fob.
Before you put the new battery into place be sure that there is no water damage or dirt on the terminals. If this is the case, clean the terminals using a small amount isopropyl ethanol. Make sure that the pole cables are connected correctly. They should be connected both the negative and the positive poles of your battery.
Troubleshooting
If your Nissan Qashqai's keys fob stops functioning after being exposed to clean water from the tap or rain, this could be a sign that there's an issue with the internal chip. You'll require a new fob if you are unable to fix the issue by replacing the battery. If you dropped the key fob on the ground and it stopped functioning immediately, this is most likely because it has damaged the internal chip. It is usually possible to get the key fob to work again if you remove and clean the chip using paper towel and isopropyl alcohol and then put it back into.
One common error you may see on your car's dashboard is "Key ID Incorrect." The vehicle is not able to recognize the key fob and consequently, won't allow the vehicle to start. This problem could be caused in numerous ways, including water damage, issues that are undetectable in the circuitry of the key fob or RFID interference.
The key fob will not function in the event that the batteries with 12 volts are dead or fail to provide sufficient electric current. This can affect the remote keyless system as well as central locking of your Nissan Qashqai, as well as stopping you from starting your engine using the key fob (if equipped with Intelligent Key). Check the batteries inside the key fob if you are not able to lock or unlock your door by hand. You could also try re-inserting the battery to reset the transmitter.
Reprogramming
If the key fob was not submerged in saltwater it should be able to come back to life by a simple wash of clean water. You can also try cleaning the electronic chip using isopropyl ethanol or an electronic cleaner. If none of these work, you may have to replace the key fob.
If your Nissan Intelligent Key is still not functioning, there may be an issue with the connection between it and the car. To relink it, start by turning the key in the ignition, without turning on the car. Repeat this process until the hazard lights flash twice. Then, turn off the car and take out the key.
Open the fob compartment in your vehicle. It's usually located in a door jamb, on the driver's side door handle or underneath an armrest. Locate the small button labeled "program" and press it. You should hear a chime sound after the process has been completed.
Now that your Intelligent Key is relinked to the car is the time to test it out. You must stand a certain distance away from the vehicle, and click all of the buttons on it. If the lights flash and the horn squeaks this means that the key has successfully linked to the Nissan. You can also test it close to the Nissan.
