Understanding the 1991 F150’s Anti-Theft System
The 1991 F150 could be equipped with a factory-installed anti-theft system, though it wasn’t standard across all trims.

Factory Installed Anti-Theft in the ’91 F150
The factory system, if present, primarily functioned as a passive deterrent. This means it automatically activated when the key was removed from the ignition. Unlike modern systems with alarms and immobilizers, the ’91 F150’s anti-theft focused on preventing unauthorized starting.

Determining if your ’91 F150 has the original anti-theft system can be tricky. The easiest way is to check the owner’s manual. Look for any mention of a “theft deterrent system” or similar wording.
