If your break away switch looks like # HM20010 then you should just have to push the pin back in. This will break the circuit and release the trailer brakes. If this does not work then there is some other wiring issue going on. You will need to remove power from the system to get the brakes to release.

You can do this by disconnecting the break away system battery (just remove the power wire from the positive battery terminal). After the brakes release you will want to determine the cause of the malfunction. If the switch is not working properly it will need to be replaced.

You will also want to inspect the wiring and repair any damaged wires, exposed copper strands touching the metal trailer frame, and make sure all grounds are attached to clean and corrosion free bare metal surfaces. I have included a couple of FAQ links on break away systems for you.
