Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai has a distinct SUV feel to it thanks to its larger dimensions. Additionally, the 19-inch wheels on Ti and ST-L models can be a bit spongy at times. The front tyres of the Qashqai are also prone to losing traction on rough surfaces, and the CVT may occasionally display wrist-flexing torque steering.

Water Damage
One of the most common reasons that a Nissan key fob displays the "key ID incorrect" message is due to water damage. The key fob has rubber seals which protect the chip inside. However, prolonged exposure to moisture could cause it to cease functioning properly. It's common to see this happen if your key fob was dropped in the water or a swimming pool.

The batteries last for about 3-5 years, but they can become faulty over time in the event that the fob has been frequentedly dropped. You can replace the battery with a new one, but make sure it's the same voltage and size as the original. If you use a new battery, it could cause the key to be assigned a wrong key ID. This could prevent it from being connected to your vehicle.
