The Qashqai's large dimensions give it a distinct SUV-like feel. Its 19-inch alloy wheels on Ti and STL versions may also be a bit firm. Its front tyres can also lose grip on rough surfaces, and its CVT may occasionally exhibit wrist-flexing torque steer.
This is usually due to an unresponsive coin battery that is easily replaced in just a few minutes. Make sure that the replacement battery is of the same size, voltage and specifications.
Water Damage
Water damage is one of the most common causes for an Nissan keyfob to display the "key ID incorrect" message. The rubber seals on the key fob guard the chip's electronic circuit, but prolonged exposure to moisture could cause it to not function properly. It's normal to see this if your keyfob has been dropped in the water or a swimming pool. However, it could also occur when it becomes wet from rain or soapy hands.
If your key fob was exposed to water for a long period of time, you may need to clean it with isopropyl, or an electronic cleaner. It could also have to be sent to a specialist to repair or replace it.
If your key fob has to be replaced, it's an easy process. First, ensure that you have a multipack with the correct battery (CR2032 3V). Then, open the back and front cases with the small flathead screwdriver. Remove the metal clips, then remove the battery, and then replace it. Reassemble the fob and replace the mechanical key. Check that it works correctly. If not then you'll need to take it to an Nissan dealer or professional auto locksmith for the replacement of the chip in the key. The chip is usually not damaged by water and therefore shouldn't be too expensive.
Dead Coin Battery
The coin battery is a second common reason for why your Nissan Qashqai remote key fob might not work. The batteries typically last for 3-5 years, but they can become depleted over time, especially if the fob is frequently dropped. You could replace the battery but be sure to use the same voltage and the same dimensions as the original. If you use a new battery, it could cause the key to be assigned a different key ID. This will prevent it from being paired with your vehicle.
The best way to replace the battery on a Nissan Qashqai key fob is by opening the key fob using an incredibly small screwdriver with a flat head. The screwdriver should be inserted into a small hole on the bottom of your key fob. Simply twist the screwdriver to separate the two halves. Then, remove the old CR2025 button cell battery and insert an alternative one after taking note of its position on the fob.
Examine the terminals for dirt or water damage prior to installing the new battery. If there is clean the terminals using a small amount isopropyl ethanol. Make sure that the pole cables are properly connected. They should be connected both the positive and negative poles of your battery.
Troubleshooting
If your Nissan Qashqai's primary fob stops working after exposure to water that is clean from a tap or rain it could be a sign that there is an issue with the internal chip. Change the battery won't fix the issue, and you'll need to buy another 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 replace it with the key fob, you will typically get it working again.
Key ID Incorrect is a common error that you can see on the dashboard of your car. This means that the vehicle is unable to recognize the key fob, and will not allow it to start the engine. The problem can be caused by many things such as water damage, undetectable problems in the circuitry of the key fob or RFID interference.
If the 12 volt battery in your key fob is broken or is not supplying sufficient electric current it will cease to function. This will affect the remote keyless system as well as central locking in your Nissan Qashqai, as well as stopping you from starting your engine with the key fob (if equipped with Intelligent Key). If you are unable to unlock or lock the door manually You should examine the batteries inside your key fob to be sure they're in good shape. You may also try reinserting the battery to reset the transmitter.
Reprogramming
If the key fob was not submerged into saltwater, it should be able return to life with a simple wash of clean water. You can also clean the electronic chip using isopropyl or electronic cleaner. If none of these works then you might need to replace the key fob.
If your Nissan Intelligent Key is still not working, there could be a problem with the connection between it and the car. To relink it, start by turning the key into the ignition, without turning on the car. Repeat this process until the hazard light flashes twice. Then, turn off your vehicle and remove the key.
Next, open the fob compartment in your vehicle. It is usually located on a door jamb or driver's door handle. Find the small "program" button and press it. You will hear a chime when the process is completed.
It's time to put your Intelligent Key to the test. Make sure you press all the buttons on the key while standing a distance away from the car. If the lights flash and the horn beeps it means that the key has been successfully linked to the Nissan. You can also test it close to the Nissan.
