Reasons Why Your Nissan Qashqai Key Fob Won't Work
The Qashqai has a distinctly SUV feel to it thanks to its bigger dimensions, and the ride on 19-inch wheels in Ti and ST-L models can be a bit stiff at times. The front tyres on the Qashqai can also lose grip on rough surfaces and its CVT can occasionally display wrist-flexing torque steering.
This is typically caused by an inoperable coin battery, which can be replaced in a matter of minutes. Make sure the replacement battery is the same voltage, size and specifications.
Water Damage
One of the most frequent reasons a Nissan key fob displays the "key ID is incorrect" message is due to water damage. The rubber seals on the key fob guard the chip's electronic circuit, but prolonged exposure to moisture could cause it to malfunction correctly. This is often the case in the event that you've dropped your key fob into the ocean or a pool in a pool, but it can also happen if it gets wet due to soapy hands or rain.

After reassembling the fob put the mechanical key back in position and ensure that it functions as intended.

Dead Coin Battery
The coin battery is a second frequent reason why your Nissan Qashqai remote key fob might not function. The batteries typically last for 3-5 years, but they can become depleted in time, particularly if the fob is dropped frequently. You can replace the battery, but make sure it is the same voltage and the same dimensions as the original. If you are using a different battery, it can cause the key to have an invalid key ID that could hinder it from paired with your vehicle.
The best method to replace the coin battery on the Nissan Qashqai key fob is by removing the fob with an small screwdriver that has a flat head. The screwdriver should be inserted into a small notch on the bottom of the fob, and twist gently to separate the two halves of the key fob. Remove the old CR2025 battery and replace it with a new one, taking note of the location of the old one within the fob.
Check the terminals for water damage or dirt before installing the new battery. If there is, clean the terminals with a small amount of isopropyl alcohol. Make sure that the pole cables are connected correctly. They should be connected to both the positive and negative poles of your battery.
Troubleshooting
If your Nissan Qashqai's key fob stops working after being exposed to pure rainwater or clean tap water it could be a sign there's an issue with the internal chip. You'll require a new keyfob if you can't resolve the issue by replacing the battery.

If you clean the chip with isopropyl alcohol and paper towel and then replace it with the key fob, you can usually get it working again.
Key ID Incorrect is a typical error that you can see on the dashboard of your vehicle. This means that the vehicle is unable to recognize the key fob and will not allow it to start the engine.
