This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Jeep Gladiator
The security / anti-theft light on a Jeep Gladiator 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?
Urgency level for this indicator on the Jeep Gladiator: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Security / Anti-Theft Light appeared, how the Jeep Gladiator is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Can I keep driving with the Security / Anti-Theft Light on?
