What the Security / Anti-Theft Light Means on a Honda Civic Type R

The security / anti-theft light on a Honda Civic Type R normally blinks to show the alarm and immobiliser are armed. If it behaves oddly or blocks starting, it can indicate a key recognition or alarm system fault.

How Urgent Is the Security / Anti-Theft Light?

Urgency level for this indicator on the Honda Civic Type R: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Security / Anti-Theft Light appeared, how the Honda Civic Type R is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Can I keep driving with the Security / Anti-Theft Light on?

For a Honda Civic Type R, a steady amber Security / Anti-Theft Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.

How much does it cost to fix the Security / Anti-Theft Light on a Honda Civic Type R?
