G28 Car Keys Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai has a distinct SUV feel due to its larger dimensions, and the 19-inch wheels on Ti and ST-L models can be a bit spongy at times. Its front tyres can also lose grip on rough surfaces and its CVT can occasionally display wrist-flexing torque steer.
This is usually caused by a dead battery that can be replaced in just a few minutes. Make sure that the new battery has the same size, voltage and specifications.
Water Damage
Water damage is among the most common reasons for an Nissan keyfob to display the "key ID incorrect" message. The rubber seals on the key fob guard the electronic chip, but prolonged moisture exposure can cause it to malfunction effectively. It's typical to observe this happen if your key fob has been dropped in the ocean or swimming pool. However, it could also occur when it's wet from showers or soapy hands.
If your key fob is exposed to water for a long period of time, it could need to be cleaned with isopropyl alcohol, or electronic cleaner. It could also require to be taken to a specialist to repair or replace it.
If your key fob does require replacement, the procedure is relatively easy. Make sure you have the correct multipack (CR2032, 3V). Open the back and front cases with the small flathead screwdriver. Remove the clips made of metal, then remove the battery, and then replace it. Reassemble the fob and replace the mechanical key. Verify that it is working properly. If not then you'll have to bring it to a local Nissan dealer or a professional auto locksmith to fix the chip that controls the key. Fortunately the chip isn't normally damaged by exposure to water, so this should not be a major expense.
Dead Coin Battery
Another reason that the reason your Nissan Qashqai key fob may not work is because the battery inside is dead. These batteries last 3-5 years, but they will eventually fail if the fob has been dropped often. You could try replacing the battery with a new one, but be sure that it's the same size and voltage as the original. If you use a new battery, it may cause the key to be assigned a wrong key ID. This will stop it from being linked to your vehicle.
The best way to change the battery of a coin in a Nissan Qashqai Key Fob is to pry it open using an incredibly small screwdriver. Push in the screwdriver in tiny notch at the bottom of the fob and twist gently to separate the two halves of the key fob. Then, take out the old CR2025 button cell battery and replace it with an alternative one after taking note of its position in the fob.
Before putting the new battery in ensure that there isn't any dirt or water damage on the terminals. If not clean the terminals using small amounts of isopropyl alcohol. Make sure that the pole cables are properly connected. They should be connected to the positive and negative poles of your battery.
Troubleshooting
If your Nissan Qashqai key fob stops working after exposure to pure rain or tap water, it may be an indication of an internal chip issue. The battery replacement won't fix this, and you'll have to buy a new key fob. If you dropped the key fob on the ground and it stopped working immediately it is likely because it has damaged the internal chip. If you clean the chip with isopropyl ethanol and a paper towel and then replace it with the key fob, it is possible to typically get it working again.
Key ID Incorrect is a typical error you may see on the dashboard of your car. This means that the vehicle is unable to recognize the key fob and not allow it to start the engine. The problem can be caused by a variety of things like water damage, undetectable issues in the circuitry of the key fob or RFID interference.
The key fob will stop working if the 12 volt batteries are dead or don't provide enough electrical current. This can affect your Nissan Qashqai's keyless system central locking, as well as the ability to start the engine with the key fob. If you are unable to lock or unlock the door manually it is recommended to check the batteries on your key fob to be sure they're in good condition. Try reinstalling the battery to reset your transmitter.
Reprogramming
If the key fob is 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 chip using isopropyl or electronic cleaner. If none of these work 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 your car. Start by pressing the ignition key, but without activating the vehicle. Continue doing this until you see the danger lights flash twice. Then, turn off the vehicle and take off the key.
Then, open the fob compartment of your vehicle. It is typically located in a door jamb, on the handle of the driver's side, or under an armrest. Find the small "program" button and press it. Once the process has been completed, you should hear the sound of a chime.
It's time to test your Intelligent Key to the test. Set your feet a distance from the vehicle and hit all the buttons on it. If the lights flash and the horn beeps this means that the key has successfully connected to the Nissan. It is also possible to test it close to the Nissan.
