Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai has a distinctly SUV feel to it thanks to its larger dimensions, and the wheel sizes of 19 inches in Ti and ST-L models may be firm at times. The front tyres in the Qashqai are also prone to losing grip on rough surfaces and the CVT could occasionally display wrist-flexing torque steering.
This is typically caused by an unresponsive battery that can be replaced in a matter of minutes. Make sure the battery you replace is of the same size, voltage and specifications.
Water Damage
One of the most frequent reasons why a Nissan key fob gives the "key ID incorrect" message is due to water damage. The key fob has rubber seals that protect the chip inside. However, prolonged exposure to moisture could cause it to cease functioning properly. It's typical to observe this if your keyfob was dropped in the water or in a swimming pool. However, it could also occur when it is wet from 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 ethanol or electronic cleaner. It may also need to be taken to an expert to repair or replace it.
If your key fob does require replacement, the procedure is relatively easy. First, ensure that you have a multipack with the correct battery (CR2032 3V). Then, open https://www.thekeylab.co.uk/nissan-car-keys/ and back cases using an abrasive screwdriver. You'll need to remove the clips that hold the metal together and pull out the old battery, and then put in the new one. After reassembling the fob, put the mechanical key back in position and ensure that it operates correctly. If it does not then you'll have to take it to a local Nissan dealer or a professional auto locksmith to repair the key chip. The chip is not usually damaged by water so it shouldn't be too expensive.
Dead Coin Battery
Another reason why your Nissan Qashqai key fob may not work is because the battery for the coin is dead. The batteries last for about 3 to 5 years, but they can become faulty over time if the fob has been frequently dropped. You can replace the battery with a new one, but be sure that it's the same voltage and size as the original. If you choose to use a brand new battery, it could cause the key to be assigned an incorrect key ID. This will prevent it from being paired with your vehicle.
The best way to change the coin battery in the Nissan Qashqai Key Fob is to pry it open with an incredibly small screwdriver. The screwdriver needs to be inserted into a small notch on the bottom of your key fob. Simply twist the screwdriver to separate the two halves. Remove the old CR2025 battery and replace it with a brand new one, observing the position of the old one within the fob.
Check the terminals for water damage or dirt before installing the new battery. If there is, wash the terminals with a tiny amount of isopropyl alcohol. Make sure that the pole cables are properly connected. They should be connected to both the negative and the positive poles of your battery.
Fault Diagnosis
If your Nissan Qashqai's primary fob isn't working after exposure to clean tap or rain water, this could be a sign that there is an issue with the internal chip. Change the battery won't fix this, and you'll need to purchase the new key fob. If you dropped the key fob on the ground and it stopped working instantly it is likely because it damaged the internal chip. If you clean the chip using isopropyl ethanol and paper towel and then put it back in the key fob, it is possible to generally get it back to working.
Key ID Incorrect is a common error that can be seen on the dashboard of your vehicle. This means that the car cannot recognize the key fob, and will not allow it to start the engine. The problem can be caused by a variety of things including water damage, undetectable problems in the key fob's circuitry, or RFID interference.
The key fob will not function when the 12 volt batteries are dead or don't provide sufficient electric current. This can affect the remote keyless system and central locking on your Nissan Qashqai, as well as making it impossible to start your engine using the key fob (if equipped with Intelligent Key). Check the batteries in the key fob if it is not able to lock or unlock your door by hand. Try reinstalling the battery to reset your transmitter.
