What the Security / Anti-Theft Light Means on a Ford Puma

On the Ford Puma, 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?

How worried should you be? For the Security / Anti-Theft Light on a Ford Puma, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Ford Puma still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Common Symptoms Alongside the Security / Anti-Theft Light

When the Security / Anti-Theft Light shows up on a Ford Puma, it rarely arrives completely alone — there are usually subtle clues if you know where to look. Drivers often notice a change in how the Ford Puma responds, an unfamiliar sound, or a warning message on the instrument cluster. Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.

  • Security light blinking when locked (normal)
  • Alarm triggering unexpectedly
  • No-start with the light active
  • Key not recognised

  • Normal armed-state indication
  • Weak key fob battery
  • Faulty bonnet or door sensor triggering the alarm

Is It Safe to Drive With the Security / Anti-Theft Light On?

Professional Mechanic Tips

Field notes from Marcus Vale, ASE-Certified Master Technician
A slow, steady blink while parked is the alarm doing its job as a deterrent — that one is completely normal.
Random alarm triggers on a Ford Puma often trace to a faulty bonnet switch fooling the system into thinking it is being opened.
