What is the Tailgate Lock Solenoid all about?

“Solenoid” is a big word that simply refers to the concept at the heart of your truck’s keyless entry. Just about every modern car model has keyless entry where you just click the button on a fob and your vehicle is now open. Many even give you an option where you can click your trunk wide open too. It was only a matter of time before truck manufacturers caught on and added the technology to their tailgates. Nowadays, most people can click the tailgate on their truck open from a distance. This makes it much easier to transfer an armful of materials into the truck bed.

To answer the question, though, a solenoid is just the coil of wire that converts an electric current into a magnetic field that, then, is used for powering a switch. When it comes to your truck, a solenoid is able to flip the tailgate lock open by using this field.
