What is the reason for the Infiniti key system malfunction preventing the engine from shutting off?

Infiniti key system malfunction may be caused by the system failing to detect the key. You can try restarting the vehicle. If the vehicle cannot start normally, you can place the mechanical key close to the one-button start button, wait for the light to come on, and then start the vehicle normally. If the fault is still displayed after starting the vehicle, you need to go to the 4S shop to have the key rematched. Relevant information about braking is as follows: 1. Introduction: Refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools, or machinery. 2. Principle: The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, belt, or disc on the machine base, which generates braking torque under external force.

I just encountered an Infiniti key system malfunction last week. The car was running but couldn't turn off the engine, which was really frustrating! There are multiple possible reasons. The most common one is a dead key battery—these smart keys rely on battery power, and insufficient charge means they can't detect signals. Another possibility is a faulty antenna receiver inside the car, usually located near the steering wheel, which can malfunction due to interference from phones or other electronic devices. Software bugs are also a potential issue, like system update failures causing the program to freeze—I've tried restarting the engine or re-pairing the key to fix this. Hardware failures, such as short circuits or aging control modules, might also trigger this problem, so it's best to check the fuses and fuse box. For safety, I recommend staying calm first—try restarting the key or moving the car away from interference sources. If that doesn't work, call a tow truck to take it to a 4S shop for inspection. Don't force it to avoid engine damage.

Every time I drive my Infiniti and encounter issues with the key not turning off the car, I suspect it's due to a few common problems. The most frequent culprit is the key sensing area being blocked or dirty—keeping it in a pocket with lots of dirt can interfere with signal transmission. Another issue could be worn-out buttons inside the car, like the start button getting stuck, which causes the system to misjudge. Additionally, interference from Bluetooth devices or strong electrical signals can disrupt the receiver's operation. I always advise my friends to start with simple checks, such as replacing the key battery—an inexpensive CR2032 usually does the trick. If that doesn’t work, check the manual for a system reset or try disconnecting and reconnecting the battery to refresh the program. Don’t forget to check for software updates, as an outdated infotainment system might have compatibility issues and struggle to communicate with the key. If you can’t resolve it yourself, contact a professional technician immediately—safety first, don’t delay your drive.

Key system failure causing Infiniti to not stop, I think it's mainly due to several common reasons. The smart key sensor malfunctioned, possibly due to depleted battery or dust blocking the contact points; the car's signal reception area has issues, such as loose wiring or moisture causing short circuits; interference sources are causing trouble, I've seen strong parking lot signals affecting key operation; check if the key is placed correctly? Try replacing the battery, if that doesn't work, go to the 4S shop for a system upgrade, cost-effective and safe.
