The car with key light means that the ignition switch is trying to identify the immobilizer system or the transponder inside your key fob. This light normally goes off after starting your vehicle and when you turn on your headlights. If this isn’t happening, you may have a problem in your key fob or one of its components.
The first thing that should be done is disconnecting the battery, then reconnect it after 30 seconds. This will reset all the electrical components in your car including the computer and all its sensors. We highly recommend reading more about this in our “How To Reset Check Engine Light: Follow These 4 Easy Ways!” article where we explain how to solve this issue step-by-step, from simple troubleshooting to some really intricate ways to fix this problem.
If it doesn’t work and you still feel like something is wrong with your car keys, take it to a professional mechanic or try using another set of car keys if you are not alone on this trip! There are two main reasons why this could happen: either one of your keys has been compromised (lost or stolen) or something is wrong with one of its components that needs replacement immediately.
The key icon is constantly on because your key fob is trying to connect to your vehicle
The key icon is constantly on because your key fob is trying to connect to your vehicle. The key fob is trying to connect to your vehicle because the engine is on or because the battery isn’t fully charged.
Typically, this icon flashes when you press the car’s start button but stays on once you place the car into drive mode. If your key icon remains lit and doesn’t flash, it could mean that there’s a problem with either the key fob or smart entry system. You’ll want to check out a few things before seeking help from a service technician:
- Make sure that you have no error codes stored in your system by visiting an authorized Honda dealership for assistance.
- Ensure that your vehicle’s battery hasn’t died by charging it overnight and making sure it has enough power to properly start up.
- Confirm that the tire pressure monitoring system hasn’t been triggered (indicated by another illuminated warning light).
It will go off when the key relay in your car detects the key fob
Your car’s key relay is a small device that lives inside your vehicle. It acts like a wireless antenna, looking for the key fob attached to your key ring. When the key fob detects that it’s in close proximity to the vehicle, it sends out a radio wave signal to the key relay, which in turn tells the car that you have your key with you and that it should unlock.
The key relay is powered by the battery of your car, and sits directly next to or underneath the steering column. It’s connected to both the ignition switch and door lock switch, so when you insert your car key into either of those switches (and start your engine or open a door), signals are sent from those switches through a series of wires until they reach their respective end points: either the starter solenoid or actuator inside the door locks.
If both sides of this arrangement work properly (the key fob and its receiver), your lights will turn off as soon as you get near enough for them to sense you have access to them.
The key icon light means that the ignition switch identify the immobilizer system or the transponder inside the fob
Your car has an immobilizer system that prevents someone from starting your car without the key. If you put the key in the ignition and try to start it, but all you hear is a clicking sound and the engine won’t turn over, there’s a good chance that either your battery or your starter is dead.
“`The key icon light means that the ignition switch identify the immobilizer system or the transponder inside the fob. It can also mean that there’s a problem with one of these components and they need to be repaired.
“`If this happens while driving, it usually means that there’s a problem with one of these components and they need to be repaired. When this happens when turning off your vehicle at night, it usually indicates that there’s been an electrical failure in one of these components (or even both).
You see the car with key light means your electronic transponder has been read by your car and it’s ready for you to turn it on.
If the key light is illuminated, it means that your electronic transponder has been read by your car and is ready for you to turn on the car. The opposite also holds true: if your key light doesn’t illuminate, then it means that your key fob hasn’t been detected by your car and it’s not ready for you to start driving. If you press the ignition button and don’t see the ‘car with key’ illuminated on your dash, check to make sure that the battery in the fob is working properly.
