I’m diving into adding some modern conveniences to my ’03 F250 SD 4×4, and keyless entry with a 2002 Ford Key Fob is high on the list. Turns out, my truck didn’t come with a VSM (Vehicle Security Module) from the factory, which is needed for features like auto lamps and keyless entry.
Aftermarket solutions are out there, and honestly, the idea of newer tech with remote start and more is tempting. But I’m curious about the VSM route. Research suggests it should be located near the fuel pedal, above the transmission hump. Has anyone confirmed this location?
UPDATE: My project has taken off! I’ve now got my hands on multiple VSMs, wiring harnesses, overhead consoles, lighted visors, and even a rearview mirror with modern features. It’s become a winter project to create a custom harness and integrate the VSM for auto lights, the overhead computer, and more. Understanding how the VSM works and fits into my truck is a learning process.
I’m planning a build thread to document this VSM upgrade for others who might be interested in adding features like keyless entry using a 2002 Ford key fob to their older trucks. Let me know your thoughts and experiences!
