The Honda Smart Key System is a convenient feature that allows you to lock, unlock, and start your Honda vehicle without physically using a key. It uses a wireless key fob that communicates with the vehicle to perform these functions.

What The Warning Light Indicates:

Ignoring the warning light could lead to difficulties in starting the vehicle or even a complete failure of the system.

Common scenarios when the warning light comes on:

• Low Battery: One of the most common reasons for the warning light to illuminate is a low battery in the key fob. When the battery is running low, the system may fail to recognize the key, triggering the warning light. Changing the battery usually resolves this issue.

This can result in the warning light appearing. Checking for any metal objects or devices near the antenna and removing them can resolve this issue.
• System Error: In rare cases, the warning light may indicate a larger system error within the smart key system. This could be due to a faulty control module or wiring issue. In such instances, it is recommended to seek professional assistance from a certified Honda technician.
