Trunk Release Solenoids

Trunk release solenoids

A solenoid is an electro-magnet with a pull rod. Send it 12 volts and it yanks the rod, which is exactly what's needed to trip a manual trunk latch. Fit one and your trunk opens from the remote or from a button inside the car instead of a key or a lever.

They're also the standard part for shaved door handle builds, where the solenoid does the whole job of releasing the door.

Standard or heavy duty?

Most trunk lids open fine on a standard solenoid. Step up to heavy duty where the lid is heavy, the latch has stiffened with age, or the solenoid is opening a door rather than a trunk. Under-specifying is the usual mistake here, and the symptom is a latch that opens most of the time but not reliably in the cold.

You will need a relay

This is the part people miss. A solenoid draws far more current than a remote starter's auxiliary output is designed to supply, so it must be wired through a relay rather than connected directly. Do it directly and you risk destroying the module's output.

That's why you'll find relays and relay harnesses listed on this page alongside the solenoids. Buy them together and the job goes in properly the first time. See our full range of relays and relay harnesses.
