Reasons Why Your Nissan Qashqai Key Fob Won't Work

The Qashqai's greater dimensions give it a distinct SUV-like ambiance. Its 19-inch alloy wheels in Ti and STL models can also be a bit firm. The front tyres of the Qashqai could also lose grip on bumpy surfaces, and the CVT may occasionally display a wrist-flexing torque steering.

This is typically caused by the battery of a coin that is dead. It can be easily replaced in minutes. Make sure the replacement battery is of the same size, voltage and specifications.

Water Damage

Water damage is one of the most common causes that cause an Nissan keyfob to display the "key ID is wrong" message. The rubber seals on the key fob are designed to protect the chip's electronic circuit, but prolonged exposure to moisture can cause it not to work properly. It's typical to observe this if your key fob has been dropped into the ocean or swimming pool. It can also occur when it becomes wet from showers or soapy hands.

If your key fob is exposed to water for a lengthy time, it may need to be cleaned using isopropyl alcohol or an electronic cleaner. It could also have to be sent to a specialist to be repaired or replaced.

If your key fob require replacement the process is simple. Make sure you have the correct multipack (CR2032 3V). Unlock the front and rear cases with the flat-head screwdriver. Remove the metal clips, take out the old battery and then replace it. Reassemble the fob and replace the mechanical key. Make sure it's working correctly. If it isn't it, you'll need to bring it to a Nissan dealer or a professional auto locksmith to repair the key chip. The chip isn't usually damaged by water, so it shouldn't be too expensive.

Dead Coin Battery

Another reason why your Nissan Qashqai key fob might not function is because the battery in the coin has gone dead. The batteries typically last for 3-5 years, but they may fail over time, especially if the fob is frequently dropped. You could replace the battery but make sure it is the same voltage and same dimensions as the original. If you install a new battery, it may cause the key to be assigned a different key ID. This could prevent it from being paired with your vehicle.

The best way to change the battery of a coin in the Nissan Qashqai Key Fob is to open it with the help of a small screwdriver with a flat head. The screwdriver needs to be inserted into a small notch at the bottom of your key fob. The screwdriver should be gently twisted to divide the two halves. Remove the old CR2025 battery and replace it with a brand new one, observing the position of the previous one inside the fob.

Before you put the new battery in place, make sure there is no dirt or water damage to the terminals. If there is, wash the terminals with a small amount of isopropyl alcohol. You'll also need to make sure the pole cables are plugged in correctly. They should be connected to the positive and negative poles of the battery respectively.

Fault Diagnosis

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. You'll need a new keyfob if you can't resolve the issue by replacing the battery. If the key fob has stopped working after dropping it, it is likely that the chip inside was damaged. It is possible to get the key fob back to work again if you remove and clean the chip with paper towel and isopropyl alcohol, then put it back into.

One common error you may see on the dashboard of your car is "Key ID Not Correct." This means that the vehicle is unable to recognize the key fob, and will not allow it to start the engine. This problem can be caused many different ways, including water damage, problems that are undetectable within the key fob circuitry or RFID interference.

The key fob won't work when the 12 volt batteries are dead or do not provide enough electrical current. This can affect the remote keyless system and central locking of your Nissan Qashqai, as well as hindering you from starting your engine using the key fob (if equipped with Intelligent Key). Check the batteries inside the key fob in case you are unable 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 had not been submerged in salt water the key fob should be able to be revived after a simple rinse with clean water. You could also try cleaning the electronic chip with isopropyl alcohol or an electronic cleaner. If these don't work, it may be time to replace the entire key fob by a new one.

If your Nissan Intelligent Key still does not function, there could be a connection problem between it and your vehicle. To relink it, start by turning the key in the ignition but without starting the car. Repeat this process until the hazard light blinks twice. Turn the vehicle off and take out the keys.

Next, you must open the fob compartment inside your vehicle. It's usually in a door jamb on the handle for the driver's door or under an armrest. Find the small button marked "program" and press it. You will hear a chime after the process is completed.

It's time to test your Intelligent Key to the test. You must stand a certain distance away from the vehicle and press all the buttons on the key. If the lights flash, or the horn sounds, the key is successfully connected to the Nissan. You may also try testing the key in close proximity.
