What Causes the Infiniti Key System Malfunction?
2 Answers
It could be due to damage to the key's control unit or the invalidation of the key's matching code. Below is relevant information: 1. Key Classification: Common types of keys on the market include mechanical keys, remote keys, touchscreen LCD keys, and smart wristband keys. Regardless of the type, their basic functions are to unlock the car door and start the engine. Some remote and touchscreen LCD keys can also perform functions like automatic parking and viewing vehicle information. 2. Remote Key: A remote key allows you to unlock and lock the car door from a distance without inserting the key into the keyhole. Its biggest advantage is that, regardless of day or night, you don't need to locate the keyhole or go through the cumbersome process of inserting the key to open the door. It enables convenient remote unlocking (opening) and locking (locking). The remote key can also open the trunk and fuel filler cap from outside the car, as well as close the windows and retract the mirrors when locking the car.
My Infiniti also had a key malfunction issue a couple of days ago, so I quickly called my trusted mechanic for advice. He mentioned several common causes: The simplest one is a dead key battery, especially in cold weather when the battery drains faster—just replace it with a CR2032 coin cell. If the key was recently dropped or got wet, the internal circuit board might have poor contact. Parking environment matters too; places near substations or large LED billboards can interfere with the signal. A faulty vehicle receiver module can cause recognition failure, and the dashboard might even show a warning light. Additionally, an aging car battery or a blown fuse can indirectly affect key functionality. The mechanic suggested first trying the spare key to rule out battery issues. If both keys fail, it’s likely an internal vehicle problem, requiring a diagnostic scan tool to check error codes. DIY repairs are too risky, so visiting a specialized repair shop is the safest option.
