Reasons Why Your Nissan Qashqai Key Fob Won't Work

Water Damage
One of the most common reasons why a Nissan key fob gives the "key ID incorrect" message is due to water damage. The rubber seals on the key fob are designed to protect the electronic chip, but prolonged moisture exposure can cause it to stop working properly. This is typically the situation when you drop your key fob in the ocean or into a swimming water pool, but it could be the case if it gets wet due to rain or soapy hands.

Dead Coin Battery

The best way to replace the battery on a Nissan Qashqai key fob is by removing the key fob using an incredibly small screwdriver with a flat head. The screwdriver should be inserted into a small notch at the bottom of the fob and turn it around gently to separate the two halves of the key fob. Then, remove the old CR2025 button cell battery and insert an alternative one after taking note of its location in the fob.
Examine the terminals to see if there is dirt or water damage prior to installing the new battery. If this is the case clean the terminals with the smallest amount of isopropylethanol. Make sure that the pole cables are properly connected. They must be connected to the negative and the positive poles of your battery.
