The magnetic lock-out key replaces the factory silver key (#34557) that comes with the trailer. The key installs easily with no tools needed, just fit the key into the trailer opening and place the magnet against the trailer frame. When the work is done, use the convenient pull-strap to release the magnet and remove the key. It's high-viz coloring serves as an easy reminder that the brakes are still locked out; always remove the key before resuming regular trailering activities. Includes one lock-out key.

This has been a great way to be able to keep using the boat and back up the trailer until I can get my trailer in for service to get the reverse wire activating the brake disengage again. I keep this nearby attached but not installed for normal driving and then when I know I'll need to back up, I find a place to pull over to point the truck/trailer slightly uphill and then the trailer brake bolt is fully disengaged, allowing this neat little device to slip in. Works perfectly.

Fitment was good. But worthless without the magnet that fell out after 1 use.

Absolutely junk. The magnets broke in half and fell out after 1st use. The entire thing started rusting within a few days.Do not wast your money and get a quality brand.

This has a really strong magnet. In fact the magnet is so strong, that when I snapped it into place the first time, the force shattered the magnet.
