Immobilizer / Key Light on a Lamborghini Revuelto
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the Immobilizer / Key Light Means on a Lamborghini Revuelto
On the Lamborghini Revuelto, this key-shaped symbol relates to the engine immobiliser. A steady or rapidly flashing light at start-up means a key recognition problem is blocking the engine.
How Urgent Is the Immobilizer / Key Light?
In terms of priority, treat this as a moderate concern on your Lamborghini Revuelto. The single most useful thing you can observe is whether the Immobilizer / Key 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 Lamborghini Revuelto drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Is It Safe to Drive With the Immobilizer / Key Light On?
Whether it is safe to keep driving your Lamborghini Revuelto with the Immobilizer / Key Light on comes down to urgency (moderate) and behaviour. As a rule, if the light is red or flashing, or the Lamborghini Revuelto 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.

Frequently Asked Questions
Why is the Immobilizer / Key Light on in my Lamborghini Revuelto?
Your Lamborghini Revuelto turned on the Immobilizer / Key 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 Immobilizer / Key Light on?
For a Lamborghini Revuelto, a steady amber Immobilizer / Key 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 Immobilizer / Key Light on a Lamborghini Revuelto?
There is no single price for the Immobilizer / Key Light on a Lamborghini Revuelto; 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 Immobilizer / Key Light reset itself on a Lamborghini Revuelto?
Sometimes the Immobilizer / Key Light on a Lamborghini Revuelto 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.
