Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai's bigger dimensions give it an SUV-like feel. Its ride on 19-inch alloy wheels in Ti and STL versions can also be a bit firm. The front tyres could lose grip on rough surfaces, and its CVT may occasionally exhibit wrist-flexing torque steer.
This is generally caused by 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 specification.
Water Damage
One of the main reasons a Nissan key fob gives the "key ID incorrect" message is due to water damage. The rubber seals on the key fob are designed to protect the chip's electronic components, however prolonged exposure to moisture can cause it not to work properly. It's normal to see this if your keyfob has been dropped in the ocean or swimming pool. It can also occur when it's wet from rain or soapy hand.

Check that it works correctly. If it doesn't it, you'll need to bring it to a Nissan dealer or a professional auto locksmith to replace the chip.

Dead Coin Battery
The coin battery is a second common reason that your Nissan Qashqai remote key fob might not function. The batteries typically last between 3-5 years, but they may fail over time, particularly if the fob is dropped frequently. You could replace the battery but ensure it's the same voltage and same size as the original. If you use a new battery, it may cause the key to be assigned an incorrect key ID. This can prevent it from being connected to your vehicle.

Then, remove the old CR2025 button cell battery and replace it with another one after confirming its position in the fob.
Before putting the new battery in place check to ensure there isn't any dirt or water damage on the terminals. 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 the positive and negative poles of your battery.

It is possible to get the key fob to work once again if it is removed and clean the chip using paper towel and isopropyl alcohol, then put it back in.
