Reasons Why Your Nissan Qashqai Key Fob Won't Work

The Qashqai's large dimensions give it a distinct SUV-like ambiance. Its 19-inch alloy wheels on Ti and STL versions can also be firm. The front tyres may lose grip on rough surfaces, and its CVT might occasionally exhibit wrist-flexing torque steer.

This is generally caused by an inoperable coin battery, which can be replaced in a matter of minutes. Be sure that the replacement battery is the same voltage, size and specifications.

Water Damage

Water damage is among the most frequent causes for a Nissan keyfob to display the "key ID is wrong" message. The rubber seals on the key fob guard the electronic chip, but prolonged exposure to moisture can cause it not to work correctly. It is common to observe this if your key fob has been dropped in the water or in a swimming pool. However, it can occur when it's wet due to the rain or soapy hands.

If your key fob has been exposed to water for a long period of time, it could need to be cleaned using isopropyl alcohol, or electronic cleaner. Alternatively, it might require a visit to an expert for repair or replacement.

If your key fob need to be replaced, the procedure is relatively simple. First, ensure that you have a multipack with the correct battery (CR2032 3V). Remove the front and back cases with a flathead screwdriver. Remove the metal clips, then remove the battery that was in place and replace it. Reassemble the fob and replace the mechanical key. Check to see if it functions properly. If not then you'll need to bring it to a local Nissan dealer or a professional auto locksmith to repair the chip on the key. The chip is not usually damaged by water and therefore isn't too costly.

Dead Coin Battery

Another common reason your Nissan Qashqai key fob may not work is because the battery for the coin is dead. These batteries last for three to five years, but may fail over time in the event that the fob has been dropped frequently. You can replace the battery, but make sure it is the same voltage and the same dimensions as the original. If you install a new nissan key battery, it may cause the key to be assigned a different key ID. This will stop it from being connected to your vehicle.

The best way to change the battery inside a Nissan Qashqai Key Fob is to break it open using the help of a small screwdriver with a flat head. Insert the screwdriver into an angled notch on the bottom of the fob and twist it gently to split the two parts of the key fob. Then, remove the old CR2025 button cell battery and replace it with a new one after noting its position in the fob.

Check the terminals for any dirt or water damage prior to installing the new battery. If this is the case clean the terminals using the smallest amount of isopropylethanol. Make sure that the pole cables are connected correctly. They should be connected to both the positive and negative poles of your battery.

Diagnostics of a fault

If your Nissan Qashqai's keys fob stops working after exposure to pure rainwater or clean tap water, this could be a sign that there's a problem with the internal chip. Change the battery won't fix the issue, and you'll need to buy an entirely new key fob. If the key fob didn't work after you dropped it, it's likely that the chip inside was damaged. If you clean the chip using isopropylethanol and paper towels and then insert it into the key fob, you can usually get it working again.

A common error that you may notice on the dashboard of your car is "Key ID Incorrect." 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 a variety of factors such as water damage, undetectable issues in the circuitry of the key fob, or RFID interference.

The key fob will cease to function in the event that the batteries with 12 volts are dead or fail to provide enough electric current. This could affect your Nissan Qashqai's keyless system, central locking and the ability to start the engine with the key fob. If you're unable to lock or unlock the door by hand it is recommended to check the batteries on the key fob to make sure they're in good shape. You could also try re-inserting the battery to reset the transmitter.

Reprogramming

If the key fob had not been submerged in salt water the key fob should be able to come back to life after a simple wash with clean water. You can also clean the electronic component using isopropyl or electronic cleaner. If none of the above works then you might need to replace the key fob.

If your Nissan Intelligent Key is still not functioning, there may be a problem with the connection between it and the car. Start by turning the ignition key without starting the vehicle. Continue doing this until the hazard light blinks twice. Turn off your vehicle and remove the key.

Then, open the fob compartment in your vehicle. It's usually in a door jamb on the handle for the driver's door, or under an armrest. Find the small "program" button and press it. After the program is complete, you should hear a chime.

It's time to test your Intelligent Key to the test. Stand some distance away from the vehicle, then hit all the buttons on it. If the lights flash and the horn squeaks, it means that the key has successfully connected to the Nissan. You can also test it near the Nissan.
