The Qashqai has a distinct SUV-like feel due 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 of the Qashqai can lose grip on rough surfaces and its CVT may occasionally exhibit wrist-flexing torque steer.
This is usually due to an inoperable coin battery, which can be repaired in a matter of minutes. Be sure that the replacement battery has the same size, voltage, and specification.
Water Damage
Water damage is among the most common causes that cause a Nissan keyfob to display the "key ID incorrect" message. The rubber seals on the key fob are designed to protect the chip's electronic components, however prolonged moisture exposure can cause it to not function correctly. This is often the case when you drop your key fob into the ocean or into a swimming pool, but it can happen when it's wet due to rain or soapy hands.
If your key fob has been exposed to water for a lengthy period of time, it could need to be cleaned using isopropyl alcohol or an electronic cleaner. In addition, it may require a visit to an expert to repair or replace it.
If your key fob has to be replaced, it's a relatively simple procedure. First, make sure you have a multipack with the correct battery (CR2032 3V). Then, open the front and back cases with the small flathead screwdriver. You'll need to remove the clips for retaining metal and push out the old battery, then replace it with the new one. After reassembling your fob, put the mechanical key back in place and verify that it is working correctly. If not, you'll need to take it to an Nissan dealer or professional auto locksmith to repair the chip in the key. The chip isn't usually damaged by water so it should not cost a lot.
Dead Coin Battery
The coin battery is a second common reason that your Nissan Qashqai remote key fob might not work. These batteries last three to five years, but are prone to failure over time in the event that the fob has been frequentedly dropped. You could replace the battery but make sure it is the same voltage and the same dimensions as the original. If you use an alternative battery, it could cause the key to have an untrue key ID, that could hinder it from pairing with your vehicle.
The most efficient method of replacing the battery on a Nissan Qashqai key fob is by prying open the fob with an small screwdriver that has a flat head.

Remove the old CR2025 battery and replace it with a brand new one, noting the position of the old one in the fob.

You'll also need to make sure the pole cables are connected correctly. They should be connected to the positive and negative poles of the battery, respectively.
Diagnostics of a fault
If your Nissan Qashqai's key fob doesn't function after exposure to clean tap or rain water, this could be a sign there's an issue with the internal chip. Change the battery won't fix the issue, and you'll need to purchase another key fob. If you dropped the key fob on the ground and it stopped working instantly it's likely due to the damage to the internal chip.

The problem can be caused by a variety of things such as water damage, undetectable malfunctions in the key fob's circuitry, or RFID interference.

This can affect the remote keyless system as well as central locking on your Nissan Qashqai, as well as stopping you from starting your engine using the key fob (if equipped with Intelligent Key). Examine the batteries on the key fob if you are in a position to lock or unlock your door manually. You may also try reinserting the battery to reset the transmitter.
Reprogramming
If the key fob is not been submerged in salt water and is unable to be revived after a quick wash with clean water. You can also clean the electronic chip using isopropyl or electronic cleaner. If these methods don't work It could be the time to replace the entire key fob with a new one.
If your Nissan Intelligent Key still does not function, there may be a problem with the connection between it and the vehicle. To reconnect it, begin by turning the key in the ignition, without turning on the car. Continue this process until you see the warning lights flash twice. Turn the vehicle off and take away the keys.
Then, open the fob compartment in your vehicle. This is usually located in a door jamb on the handle of the driver's side or under the armrest. Find the button that says "program" and press it. You should hear a chime sound after the process is completed.
Now that your Intelligent Key is relinked to the car now is the time to try it out. You must stand a certain distance away from the vehicle, then press all the buttons on the key. If the lights flash or the horn sounds, then the key is connected to the Nissan. It is also possible to test it close to the Nissan.
