When I travel with my snowmobile, I do not like to take chances with its security. It is far too easy to cut off a cheap lock and take off with my trailer and multiple sleds. Fortunately, there are some heavy-duty locks out there to give you peace of mind when leaving your trailer for the night.

Snowmobiles seem to get more expensive every season. They are not worth losing to a thief! A good trailer lock is not cheap either, and all the different kinds of locks to choose from can seem confusing.

I have done the research and tested from the cheapest to the most expensive trailer locks around. Below you will find some tips to help you find the lock that will pretty much guarantee your sled’s security.

Reviews of the Best Snowmobile Trailer Locks

1. Amplock Coupler Lock

Amplock Coupler Lock

This is one of the pricier trailer lock systems, but you really get what you pay for with the Amplock Coupler Lock. There are a few different variations of it to fit different sized couplers.

It is made from steel and comes with three pieces, including the key. The steel ball that fits into the coupler is virtually impossible to get through with a drill, crowbar, or any other device that a thief might employ. Even though this lock is expensive, it is ready to go out of the box; no additional parts are required to lock up your trailer.

No lock is perfect, however. There have been reports of the steel ball freezing to the coupler in harsh conditions.

Also, the keyhole to unlock the trailer is on the bottom of the longer piece of steel attached to the ball. It is slightly annoying to have to go from underneath, but this is actually a good thing, as it makes it all the more difficult to get a drill underneath the trailer to try to compromise the lock.

Besides, you only have to use the key when you are unlocking the trailer as the keyhole pushes in to lock.


  • Sturdy
  • Only push keyhole to lock
  • Only three small pieces


  • The ball may freeze in extreme conditions
  • Expensive

2. Abus Rekeyable Padlock

Abus Rekeyable Padlock

The Abus Rekeyable Padlock has a beautiful rounded steel top and a thick steel body to prevent bolt cutters of any kind.

It is far cheaper than the Amplock, but it does not come with everything you need right off the bat. You will have to take it to a locksmith to get the blank key fitted, but this also means that if you lose your keys, you can make a new one.

You will also need to buy a chain and fit it through your trailer’s wheel. I have used this lock in the past with a steel square linked chain. The square links make it harder for a bolt cutter to get a grip on the chain.

Those two characteristics add more cost to securing your snowmobile trailer, but it most likely will end up coming up cheaper than the Amplock.

A huge win for this lock is that it holds up in the freezing temperatures. The smoothness of the locking/unlocking mechanism is unmatched.

The keyhole is also more easily accessed, but if a thief really wanted to drill into the lock, they might be able to after a decent amount of time.


  • Cheap
  • Rekeyable
  • Non-freezing locking mechanism


  • Requires a locksmith to customize key
  • Requires a chain
  • Slightly compromised at the keyhole

How to Choose the Best Lock for a Snowmobile Trailer – Buyer’s Guide

Protecting your snowmobile trailer is of the utmost importance. Sleds are not cheap these days, so leaving them unattended without a trailer lock can be a very expensive mistake.

Not all trailer locks are created equal. Some can be compromised in as little as thirty seconds with a power drill. Below are some characteristics to consider when shopping for a lock to protect your trailer and your snowmobiles.


The strength of the metal is probably the most important thing to look for when purchasing a trailer lock. When the metal is thick and hard and not easily cut with bolt cutters or a drill, it will deter even the most determined thief.

In my opinion, steel locks are the only way to go, but you have to be careful. Some locks are advertised as steel but have aluminum mechanisms near the keyhole. It makes for an easy thirty second of drilling to pop the lock. It is very important that all the components are made of steel.

Easy to use in the snow

Since the lock will almost always be used in the presence of snow and ice, the key function needs to be of high quality.

One of my first years riding, I bought a cheap lock because I live in a pretty safe area and did not think I needed to invest in a burly one. Almost every cold day that season the key function on the lock froze and I ended up buying a blow torch to try to defrost it until I got so frustrated, I just ditched it.

As I got better at riding and started buying nicer snowmobiles, I invested in a strong lock with a high-quality key function.

Every now and then, even the best of locks freeze, but one of my rider friends showed me a hack that works really well. If you melt Vicks VapoRub down in a pot and throw your lock in it, it will prevent it from freezing.

Ready to use out of the box

Even though some lock choices seem pricey, they might be a better deal when everything is said and done. Some locks might seem tough and cheap, but require extra parts that cost time and money.

Some might need a large chain or come with a blank key that must be taken to a locksmith to use. When comparing prices, just make sure you know exactly what the lock comes with before settling on the cheaper one. 

My Choice for the Best Snowmobile Trailer Lock

While some riders prefer a less expensive lock, I think the Amplock Coupler Lock is well worth the money to dissolve any anxiety that comes with walking away from your belongings, and it’s, therefore, my top pick for the best snowmobile trailer lock.

It will stop almost any tools used to disarm it. It’s sleek and does not require bulky chains or lots of pieces to remember. Best of all, it’s ready to use right out of the box.

However, the Abus Rekeyable Padlock is a great alternative if you are looking to spend a little less money. It’s still a very reliable lock with its only weak point being the keyhole. If you spend more time in a low crime area with very low temperatures, this lock might just be the one for you!
