Security / Anti-Theft Light on a Honda City
This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Honda City
On the Honda City, this symbol relates to the anti-theft system. A slow blink when parked is normal deterrent behaviour; erratic flashing or a no-start suggests a fault with the key or alarm module.
How Urgent Is the Security / Anti-Theft Light?
In terms of priority, treat this as a low concern on your Honda City. The single most useful thing you can observe is whether the Security / Anti-Theft Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Honda City drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
Common Symptoms Alongside the Security / Anti-Theft Light

Is It Safe to Drive With the Security / Anti-Theft Light On?
Safe-to-drive depends on judgement, and here is the technician's version for a Honda City: respect the colour, respect the behaviour. Given this light's low urgency, treat any red or flashing warning as a stop-now signal. If everything feels normal and the light is amber, a short, cautious drive to a garage is typically fine, provided you do not delay the actual diagnosis.

Random alarm triggers on a Honda City often trace to a faulty bonnet switch fooling the system into thinking it is being opened.
Frequently Asked Questions
Why is the Security / Anti-Theft Light on in my Honda City?
On a Honda City, the Security / Anti-Theft Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Security / Anti-Theft Light on?
For a Honda City, 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 City?
Cost varies widely because the Security / Anti-Theft Light can stem from several causes on a Honda City. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Security / Anti-Theft Light reset itself on a Honda City?
Sometimes the Security / Anti-Theft Light on a Honda City clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
