Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai's larger dimensions give it a distinct SUV-like ambiance. Its 19-inch alloy wheels on Ti and STL versions can also be a bit firm. The front tyres on the Qashqai can also lose grip on rough surfaces and its CVT can sometimes show wrist-flexing torque steering.
This is usually the result of a dead battery, which can be replaced in just a few minutes. Make sure the battery you replace is of the same size, voltage and specification.
Water Damage
One of the most frequent reasons that a Nissan key fob might display the "key ID is incorrect" message is due to water damage. The key fob has rubber seals that protect the electronic chip inside, however prolonged exposure to moisture can cause it to stop working properly. It's normal to see this happen if your key fob has been dropped in the ocean or swimming pool. It can also occur when it's wet from rain or soapy hand.
If your key fob was exposed to water for many years and you're not sure, clean it with isopropyl, or an electronic cleaner. It could also have to be taken to a specialist to repair or replace it.
If your key fob need to be replaced, the procedure is relatively simple. Make sure you have the proper multipack (CR2032, 3V). Unlock the front and rear cases with a flathead screwdriver. Remove the metal clips, then remove the old battery and replace it. After reassembling the fob, put the mechanical key back in its place and make sure it works as expected. If it doesn't then you'll have to take it to a Nissan dealer or professional auto locksmith to replace the key chip. The chip is usually not damaged by water and should not cost a lot.
Dead Coin Battery
The coin battery is another frequent reason why your Nissan Qashqai remote key fob won't work. These batteries usually last 3-5 years, but they are susceptible to becoming depleted over time, particularly when the fob is dropped frequently. You can replace the battery but make sure it is the same voltage and the same size as the original. If you use a 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 most effective method of changing the coin battery in the Nissan Qashqai Key Fob is to break it open using the help of a small screwdriver with a flat head. In the screwdriver, push it into a small notch at the bottom of the fob, and turn it around gently to separate the two halves of the key fob. Remove the old CR2025 battery and replace it with a new one, noting the position of the old one in the fob.
Before putting the new battery in, make sure there is no dirt or water damage on the terminals. If there is, wash the terminals with a tiny amount of isopropyl alcohol. You should also ensure that the pole cables are plugged in correctly. They should be connected to the negative and positive poles of the battery respectively.
Troubleshooting
If your Nissan Qashqai key fob stops working after exposure to clean rain or tap water, it may be an indication of an internal chip issue. Change the battery won't fix the issue, and you'll need to purchase another key fob. If the key fob stopped working after you dropped it, it is likely that the chip inside was damaged. It is possible to get the key fob back to work once again if it is removed and clean the chip with paper towel and isopropyl alcohol, then put it back in.
One common error you will see on your dashboard is "Key ID Not Correct." This means that the vehicle is unable to recognize the key fob and not allow it to start the engine. The issue can be caused by many things such as water damage, undetectable malfunctions in the key fob's circuitry, or RFID interference.
The key fob will not function in the event that the batteries with 12 volts are dead or don't provide enough electric current. This can affect the Nissan Qashqai's remote keyless system central locking, as well as the capability to start the engine with the key fob. Check the batteries in the key fob if it is in a position to lock or unlock your door manually. You may also try reinserting the battery to reset the transmitter.
Reprogramming
Unless the key fob has been submerged in salt water, it should be able to be restored to its original state after a simple wash with clean water. You could also try cleaning the electronic chip with isopropyl alcohol or an electronic cleaner. If none of these works then you might need to replace the key fob.
If nissan car key does not work, there might be a problem connecting between it and the vehicle. To relink it, start by turning the key in the ignition but without starting the car. Continue doing this until the hazard light flashes twice. Then, turn the vehicle off and take the keys out.
Open the fob compartment of your vehicle. This is usually located in a door jamb, on the handle of the driver's side or underneath an armrest. Find the small "program" button and press it. You will hear a chime once the process is complete.
