Security / Anti-Theft Light on a Porsche Taycan
This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Porsche Taycan
The security / anti-theft light on a Porsche Taycan normally blinks to show the alarm and immobiliser are armed. If it behaves oddly or blocks starting, it can indicate a key recognition or alarm system fault.
How Urgent Is the Security / Anti-Theft Light?
In terms of priority, treat this as a low concern on your Porsche Taycan. 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 Porsche Taycan drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Alongside the Security / Anti-Theft Light, Porsche Taycan owners commonly report a handful of related signs. Some are obvious, others easy to miss until you pay attention.

Can I keep driving with the Security / Anti-Theft Light on?
For a Porsche Taycan, 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 Porsche Taycan?

Will the Security / Anti-Theft Light reset itself on a Porsche Taycan?
