How can I prevent trailer theft when it’s unhitched?

A trailer coupler lock is a great option! It fits over the coupler and makes it almost impossible for someone to hitch your trailer to their vehicle. It’s an easy way to get peace of mind. Check out this FAQ for a full guide.

How do I secure my ball mount or bike rack?

Swap out your regular hitch pin for a hitch receiver lock. It works like a hitch pin but has a key, so no one can just walk off with your ball mount or bike rack. The etrailer Trailer Hitch Receiver Lock is a solid choice for most 2-inch hitches.

Is there a way to use just one key for all my trailer and hitch locks?

Some lock sets are “keyed alike,” meaning one key works for all of them. It’s super convenient. It's a great solution for securing your hitch receiver and trailer coupler without needing a bunch of keys.

How can I stop someone from towing or rolling away my trailer?

Wheel locks are the way to go! They clamp onto your trailer’s wheel and make it impossible to roll. Pair one with a coupler lock for extra security.

Can I lock my trailer coupler while it’s hooked up to my vehicle?

A coupler latch lock is perfect for this. It locks the latch on the coupler so no one can disconnect your trailer. They're easy to use and super secure.
