Reasons Why Your Nissan Qashqai Key Fob Won't Work

The Qashqai has a distinct SUV feel to it thanks to its larger dimensions, and the wheel sizes of 19 inches in Ti and ST-L models may be a bit spongy at times. The front tyres on the Qashqai are also prone to losing traction on rough surfaces, and the CVT may occasionally display a wrist-flexing torque steering.

This is usually due to an unresponsive coin battery that can be easily repaired in a matter of minutes. Make sure the replacement battery is of the same voltage, size and specifications.

Water Damage

Water damage is one of the most common causes that cause the Nissan keyfob to display the "key ID incorrect" message. The key fob has rubber seals which protect the chip inside, however prolonged exposure to moisture can cause it to cease functioning properly. This is typically the case when you've dropped your key fob in the ocean or into a swimming pools, but it could be the case if it gets wet from rain or soapy hands.

If your key fob has been exposed to water over an extended period of time and you're not sure, clean it using isopropyl and electronic cleaner. Or, it could need to be taken to a specialist to repair or replace it.

If your key fob does require replacement the process is easy. First, make sure that you have a multipack of the right battery (CR2032 3V). Then, open the back and front cases using the small flathead screwdriver. Remove the metal clips, then remove the battery that was in place and replace it. After reassembling the fob, put the mechanical key back into position and ensure that it works as expected. If it isn't then you'll have to take it to a nissan spare key dealer or a professional auto locksmith to repair the key chip. The chip is not usually damaged by water and therefore shouldn't be too expensive.

Dead Coin Battery

The coin battery is a second common reason why your Nissan Qashqai remote key fob won't work. The batteries typically last between 3-5 years, but they may fail with time, particularly when the fob is frequently dropped. You can replace the battery but make sure it is the same voltage and the same size as the previous. If you use a different battery it may cause the key to have an untrue key ID, that could hinder it from paired with your vehicle.

The most efficient method of replacing the battery in a Nissan Qashqai key fob is by removing the key fob using an small screwdriver that has a flat head. The screwdriver needs to be inserted into a small notch at the bottom of your key fob. Simply twist the screwdriver to divide the two halves. Then, remove the old CR2025 button cell battery and insert another one after confirming its location on the fob.

Examine the terminals to see if there is dirt or water damage prior to installing the new nissan key battery. If there is clean the terminals with small amounts of isopropyl alcohol. Make sure that the pole cables are connected correctly. They should be connected to both the negative and the positive poles of your battery.

Diagnostics of a fault

If your Nissan Qashqai key fob stops working after exposure to clean rain or tap water, it may be a sign of a chip issue inside. You'll require a new keyfob if you can't solve the issue by changing the battery. If the key fob has stopped working after dropping it, it is likely that the chip inside was damaged. It is usually possible to get the key fob back to work once again if it is removed and clean the chip using alcohol and paper towels before putting it back in.

One common error you will see on the dashboard of your vehicle is "Key ID Not Correct." The vehicle is not able to recognize the key fob, and thus won't allow the vehicle to start. The issue can be caused by a variety of things including water damage, undetectable issues in the key fob's circuitry or RFID interference.

If the 12 volt battery on your key fob is broken or is not supplying enough electric power it will cease to function. This can affect the remote keyless system as well as central locking of your Nissan Qashqai, as well as hindering 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 may also try replacing the battery to reset your transmitter.

Reprogramming

If the key fob was not submerged into saltwater it should be able to return to life by a simple wash of clean water. You can also clean the electronic chip with isopropyl or electronic cleaner. If none of these works, you may need to replace the key fob.

If your Nissan Intelligent Key still does not function, there may be a problem with the connection between it and your vehicle. To reconnect it, start by turning the key in the ignition without starting the car. Continue to do this until you see the hazard lights flash twice. Then, turn off the car and take out the key.

Then, then open the fob compartment in your vehicle. It's usually on a door jamb or the handle for the driver's door. Find the small "program" button and press it. After the program is complete you will hear an audible sound.

It's time to put your Intelligent Key to the test. Click all the buttons on the key while standing a distance from the vehicle. If the lights flash and the horn sounds it means that the key has successfully linked to the Nissan. You may also try testing the key in close proximity.
