Immobilizer / Key Light on a Skoda Citigo
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the Immobilizer / Key Light Means on a Skoda Citigo
The immobiliser / key light on a Skoda Citigo normally blinks when the car is locked (anti-theft armed). If it flashes while trying to start, the car is not recognising your key and will not start.
How Urgent Is the Immobilizer / Key Light?
How worried should you be? For the Immobilizer / Key Light on a Skoda Citigo, the urgency is moderate. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Skoda Citigo 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.

Is It Safe to Drive With the Immobilizer / Key Light On?
Safe-to-drive depends on judgement, and here is the technician's version for a Skoda Citigo: respect the colour, respect the behaviour. Given this light's moderate 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.
Professional Mechanic Tips
On a Skoda Citigo that will not start with a flashing key light, holding the fob directly against the start button often lets the immobiliser read a weak transponder.
Always keep a working spare key — it instantly tells you whether the problem is the key or the car's immobiliser.
