The Keylab Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai has a distinctly SUV feel to it thanks to its bigger dimensions, and the ride on 19-inch wheels in Ti and ST-L models may be a bit firm at times. The front tyres in the Qashqai may also lose grip on rough surfaces, and its CVT can sometimes display wrist-flexing torque steering.
It is usually caused by an unresponsive coin battery that is easily replaced in just a few minutes. Make sure the battery you replace is of the same voltage, size and specifications.
Water Damage
Water damage is one of the most common causes that cause the Nissan keyfob to display the "key ID wrong" message. The key fob comes with rubber seals which protect the chip inside, but long-term exposure to moisture can cause it not to function properly. It's common to see this if your keyfob has been dropped into the ocean or in a pool. It can also occur when it is wet from rain or soapy hands.
If your key fob has been exposed to water for the course of a long time, you may need to clean it with isopropyl or electronic cleaner. It could also have to be taken to an expert to repair or replace it.
If your key fob require replacement, the procedure is relatively easy. Make sure you have the correct multipack (CR2032 3V). The front and rear cases with the flat-head screwdriver. You'll have to remove the retaining clips made of metal and then push out the old battery, then insert the new one. After reassembling the fob put the mechanical key back into its place and make sure it functions as intended. If not, you will need to take it to your local Nissan dealer or an experienced locksmith to replace the chip in the key. Fortunately the chip isn't usually damaged by water exposure and therefore this shouldn't cost you a lot.
Dead Coin Battery
Another reason why your Nissan Qashqai key fob might not work is that the battery inside is dead. The batteries typically last for 3-5 years, but they are susceptible to becoming depleted with time, particularly when the fob is dropped frequently. You can replace the battery, however, make sure it's the same voltage and same size as the previous. If you use a new battery, it could cause the key to be assigned a different key ID. This could prevent it from being paired with your vehicle.
The best method to replace the battery in a Nissan Qashqai key fob is by opening the key fob using an small screwdriver that has a flat head. The screwdriver must be inserted into a small cut on the bottom of your key fob. Make sure to gently twist the screwdriver to divide the two halves. Then, take out the old CR2025 button cell battery and insert an alternative one after taking note of its position on the fob.
Before you put the new battery into place ensure that there isn't any water damage or dirt on the terminals. If not clean the terminals using the smallest amount of isopropylethanol. Make sure that the pole cables are properly connected. They should be connected both the positive and negative poles of your battery.
Fault Diagnosis
If your Nissan Qashqai key fob stops working after exposure to pure rain or tap water it could be a sign of an internal chip issue. You'll require a new keyfob if you can't solve the issue by replacing the battery. If the key fob stopped working after dropping it, it's likely that the chip inside was damaged. It is possible to get the key fob to function once more if you remove and clean the chip using alcohol and paper towels before putting it back in.
Key ID Incorrect is a typical mistake that you might see on the dashboard of your car. This means that the vehicle cannot recognize the key fob and not allow it to start the engine. The issue could be caused by several things like water damage, undetectable problems in the circuitry of the key fob or RFID interference.
If the battery that powers 12 volts on your key fob is broken or is not supplying enough electrical current, it will stop working. This can affect the remote keyless system as well as central locking of your Nissan Qashqai, as well as making it impossible to start the engine using the key fob (if equipped with Intelligent Key). If you're unable to unlock or lock the door by hand You should examine the batteries on your key fob and make sure they are in good shape. You may also try reinserting the battery to reset the transmitter.
Reprogramming
If the key fob was not submerged in saltwater the device should be able to be revived with a simple wash of clean water. You can also try cleaning the electronic chip using isopropyl ethanol or an electronic cleaner. If these don't work, it may be time to replace the entire key fob with a new one.
If your Nissan Intelligent Key is still not working, there could be an issue with the connection between it and your car. To reconnect it, start by turning the key into the ignition, but not starting the car. Continue doing this until the hazard light blinks twice. Turn off your vehicle and remove the key.
Open the fob compartment of your vehicle. It is usually located on a door's jamb or driver's door handle. Find the small "program" button and press it. Once the process has been completed you will hear a chime.
It's time to put your Intelligent Key to the test. Stand some distance away from the vehicle, and click all of the buttons on the key. If the lights flash and the horn beeps this means that the key is successfully linked to the Nissan. It is also possible to test it close to the Nissan.
