Security / Anti-Theft Light on a Dodge Dart
This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Dodge Dart
On the Dodge Dart, 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 Dodge Dart. 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 Dodge Dart drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
Common Symptoms Alongside the Security / Anti-Theft Light
Alongside the Security / Anti-Theft Light, Dodge Dart owners commonly report a handful of related signs. Some are obvious, others easy to miss until you pay attention. Keeping a short mental (or written) log of what the Dodge Dart does when the light is on gives whoever performs the repair a huge head start and can save you money on diagnostic time.
- Security light blinking when locked (normal)
- Alarm triggering unexpectedly
- No-start with the light active
- Key not recognised
What Causes the Security / Anti-Theft Light to Come On?
Why did the Security / Anti-Theft Light come on in your Dodge Dart? The honest answer is 'it depends', but the possibilities cluster into a recognisable set of causes.

- Normal armed-state indication
- Weak key fob battery
- Faulty bonnet or door sensor triggering the alarm
- Immobiliser antenna fault
- Low vehicle battery
How to Fix the Security / Anti-Theft Light on a Dodge Dart
Fixing the Security / Anti-Theft Light on a Dodge Dart is methodical, not mysterious. Start with the quick, no-cost checks, then let the vehicle's own trouble codes guide you toward the specific system at fault. The ordered steps here are designed so that by the time you (or your technician) reach the more involved work, you have already eliminated the easy explanations.
- Replace the key fob battery
- Lock/unlock with the key in the door to reset the alarm
- Check the bonnet and door switches for false triggers
- Test the vehicle battery
- Have the alarm/immobiliser module scanned if it persists
Is It Safe to Drive With the Security / Anti-Theft Light On?
Whether it is safe to keep driving your Dodge Dart with the Security / Anti-Theft Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Dodge Dart is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.

Random alarm triggers on a Dodge Dart 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 Dodge Dart?
Your Dodge Dart turned on the Security / Anti-Theft Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Security / Anti-Theft Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Dodge Dart, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Security / Anti-Theft Light on a Dodge Dart?
There is no single price for the Security / Anti-Theft Light on a Dodge Dart; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Security / Anti-Theft Light reset itself on a Dodge Dart?
Occasionally, yes — a Dodge Dart can extinguish the Security / Anti-Theft Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
