Reasons Why Your Nissan Qashqai Key Fob Won't Work The Qashqai has a distinctly SUV-like feel due to its larger dimensions, and the wheel sizes of 19 inches 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 can occasionally display wrist-flexing torque steer. It is usually caused by a dead coin battery which is easily replaced in a matter of minutes. Make sure the battery you replace is of the same size, voltage and specification. Water Damage Water damage is among the most common reasons for the Nissan keyfob to display the “key ID is incorrect” message. The rubber seals on the key fob are designed to protect the chip's electronics, but long-term exposure to moisture can cause it not to work properly. It's common to see this happen if your key fob was dropped in the water or in a swimming pool. It can also occur when it becomes wet due to the rain or soapy hands. If your key fob has been exposed to water for a prolonged period of time, it might need to be cleaned using isopropyl alcohol or electronic cleaner. It may also need to be taken to an expert for repair or replacement. If your key fob does need to be replaced the process is easy. First, ensure that you have an appropriate multipack battery (CR2032 3V). Open the front and rear cases with the flat-head screwdriver. Remove the clips made of metal, then remove the old battery and then replace it. After reassembling the fob, put the mechanical key back into place and verify that it is working correctly. If it does not then you'll need to take it to a Nissan dealer or a professional auto locksmith for replacement of the key chip. The chip isn't usually damaged by water, so it isn't too costly. Dead Coin Battery The coin battery is another common reason for why your Nissan Qashqai remote key fob may not work. These batteries usually last 3-5 years, but they can become depleted over time, especially if the fob is frequently dropped. You could replace the battery but be sure to use the same voltage and same size as the first. If you're using a different battery it may cause the key to have an untrue key ID, which can prevent it from pairing with your vehicle. The best method to replace the battery in a Nissan Qashqai key fob is by opening the key fob using the small screwdriver with a flat-head. The screwdriver must be inserted into a small cut on the bottom of your key fob. The screwdriver should be gently twisted to separate the two halves. Then, remove the old CR2025 button cell battery and insert the new one after confirming its location on the fob. Before you put the new battery in be sure that there is no dirt or water damage to the terminals. If there is, wash www.g28carkeys.co.uk with a tiny amount of isopropyl alcohol. Make sure that the pole cables are properly connected. They must be connected to the negative and the positive poles of your battery. Fault Diagnosis If your Nissan Qashqai key fob stops working after exposure to pure rain or tap water, it may be an indication of a chip issue inside. You'll require a new keyfob if you can't fix the problem by replacing the battery. If the key fob didn't work after dropping it, it is likely that the chip inside was damaged. If you clean the chip with isopropyl alcohol and paper towel, then replace it in the key fob, you can generally get it working. Key ID Incorrect is a typical error you may see on the dashboard of your car. This means that the car cannot recognize the key fob and will not allow it to start the engine. The problem can be caused by a variety of things such as water damage, undetectable faults in the circuitry of the key fob or RFID interference. If the battery that powers 12 volts inside your key fob is empty or isn't supplying enough electric power it will cease to function. This could affect the Nissan Qashqai's keyless system, central locking and the capability to start the engine using the key fob. Examine the batteries on the key fob if you're not able to lock and unlock your door manually. You may also try reinserting the battery to reset the transmitter. Reprogramming If the key fob had not been submerged in salt water and is unable to come back to life after a simple wash with clean water. You can also clean the electronic chip by using isopropyl or electronic cleaner. If none of these work it could be time to replace the entire key fob with a new one. If your Nissan Intelligent Key still does not work, it could be a connection problem between it and your vehicle. To reconnect it, begin by turning the key into the ignition without starting the car. Continue to do this until you see the danger lights flash twice. After that, turn the car off and take out the keys. Then, open the fob compartment of your vehicle. It's usually located on a door jamb, or the handle for the driver's door. Find the small “program” button and press it. When the process is complete you will hear an emitted sound. Now that your Intelligent Key is relinked to the car now is the time to try it out. Make sure you press all the buttons on the key while standing at a distance from the car. If the lights flash or the horn sounds, then the key is connected to the Nissan. You can also test it in close proximity.
