Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai's greater dimensions give it an SUV-like ambiance. Its ride on 19-inch alloy wheels on Ti and STL versions can also be a bit firm. G28 on the Qashqai may also lose grip on bumpy surfaces, and the CVT may occasionally display wrist-flexing torque steering.
This is usually due to an unresponsive coin battery that is easily replaced in a matter of minutes. Make sure the replacement battery is of the same voltage, size and specification.
Water Damage
One of the most frequent reasons that a Nissan key fob gives the "key ID is not correct" message is due to water damage. The key fob comes with rubber seals that shield the electronic chip inside, however prolonged exposure to moisture could cause it to cease functioning properly. It's common to see this if your keyfob has been dropped in the ocean or swimming pool. However, it can happen when it gets wet due to the rain or soapy hands.
If your key fob was exposed to water for a long period of time and you're not sure, clean it with isopropyl, or an electronic cleaner. In addition, it may need to be taken to a specialist for repair or replacement.
If your key fob does need to be replaced the process is easy. Make sure you have the correct multipack (CR2032, 3V). Remove the front and back cases using the flat-head screwdriver. Remove the metal clips, take out the battery that was in place and replace it. After reassembling the fob, put the mechanical key back into place and check that it is working correctly. If not then you'll need to take it to an Nissan dealer or a professional auto locksmith for the replacement of the key chip. Fortunately, the chip is not normally damaged by exposure to water which means that this shouldn't be a major expense.
Dead Coin Battery
The coin battery is another common reason that your Nissan Qashqai remote key fob might not function. The batteries typically last for 3-5 years, but they may fail with time, particularly when the fob is frequently dropped. You can replace the battery but be sure to use 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 can prevent it from being paired with your vehicle.
The best method to replace the battery of a coin in a Nissan Qashqai Key Fob is to open it with a small flat-head screwdriver. The screwdriver should be put into a small notch at the bottom of your key fob. Gently twist the screwdriver to separate the two halves. Remove the old CR2025 battery and replace it with a brand new one, making note of the position of the old one in the fob.
Before you put the new battery in place, make sure there is no water damage or dirt on the terminals. If there is, wash the terminals using a small amount of isopropyl alcohol. You'll also want to ensure that 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's key fob doesn't function after being exposed to clean water from the tap or rain it could be a sign there's a problem with the internal chip. You'll need a new keyfob in the event that you can't resolve the issue by replacing the battery. If the key fob didn't work after dropping it, it's likely that the chip inside was damaged. It is usually possible to get the key fob to function once more if you remove and clean the chip using paper towel and isopropyl alcohol and then put it back into.
One common error you may notice on the dashboard of your car is "Key ID Not Correct." This means that the vehicle cannot recognize the key fob and will not allow it to start the engine. The issue could be caused by a variety of things, including water damage, undetectable issues in the circuitry of the key fob, or RFID interference.
The key fob will stop working when the 12 volt batteries are not working or provide sufficient electric current. This will affect the remote keyless system as well as central locking on your Nissan Qashqai, as well as stopping you from starting the engine with the key fob (if equipped with Intelligent Key). Check the batteries inside the key fob if you're not able to lock or unlock your door by hand. You can also try re-inserting the battery to reset the transmitter.
Reprogramming
Unless the key fob has been submerged in salt water the key fob should be able to be revived after a simple wash with 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 still does not work, it could be a connection problem between it and the vehicle. To relink it, start by turning the key into the ignition but without starting the car. Continue this process until you see the hazard lights flash twice. Then, turn the car off and remove the keys.
Then, you need to you must open the fob compartment inside your vehicle. It's usually located in a door jamb, on the handle on the driver's side or under the armrest. Find the small button marked "program" and press it. You will hear a sound once the process is complete.
Now that your Intelligent Key is relinked to the car It's time to test it out. Make sure you press all the buttons on the key while at a distance away from the car. If the lights flash, or the horn sounds, then the key is successfully connected to the Nissan. You can also test it close to the Nissan.
