Trailer Hitch Lock Buying Guide
When it comes to protecting your trailer, its important that you invest wisely into a trailer hitch lock. The trailer and the cargo on the trailer can cost thousands of dollars and without protection, it can all be stolen in a matter of minutes.
90% of the time, a cheap trailer lock will act as a deterrent and put those criminals off. This is because they will be looking for an easy target. However, if your trailer load is expensive but is using a weak lock, then it may be worth the criminals time and effort hammering it off. Therefore, within our recommendations we have mentioned premium alternatives that are virtually impossible to take off without the key.
How Easy Is It To Steal A Trailer?
The ease of which you give the thieves is up to you. For example, if you leave your towable possession (lets say a boat on the trailer) on your driveway, with nothing attached to it and its pointing towards the road, you are asking for trouble.
If you are towing with your vehicle and you stop for a period of time, a criminal may pounce when you are not looking. If you have not installed a trailer hitch lock, they can simply pull up, disconnect it from your vehicle and put it on theirs.
Even those with a hitch for a fifth wheel trailer, a determined criminal will be able to get past the jaw mechanism and take your trailer with them. The same can be said with a more complicated hitch such as a hitch using a weight distribution system.
As you can imagine, the first thing a criminal will try is to use brute force to remove your lock. For example, constantly hitting the trailer lock with a hammer until it falls apart. If the body is made from an aluminum or zinc material, this may eventually fall apart through the heavy impacts. Look out for hardened steel throughout the construction (such as the Proven Industries lock), which will be able to withstand heavy impact damage all day long.
When it comes to the popularity and low cost examples, the uniqueness of the keys can become an issue. For example, a criminal may have a selection of keys available to them and it is a matter of trail or error that may result in a match.
Brands that mention that they have thousands or millions of key combinations are highly recommended. Ensure you keep the packaging or note down the unique code of your key because you may be in trouble if you ever lose the key.
Flaws with Cheap Locks
With a trailer hitch lock, you really do get what you pay for. The cheaper alternatives will always be easier to unlock than the more expensive coupler locks. One of the most popular locks in the US (Reese Towpower) has been known to break easily if you hit the aluminum body with a hammer a few times. However, it gets worse as you can watch this video, it demonstrates the effectiveness of the Proven Industries compared to cheap alternatives.
With that being said, it still acts as an excellent deterrent to those looking for a trailer that is quick and easy to steal. It remains within our recommendations primarily for that reason alone and it does hold some security values for your trailer whilst also being cheap.
Not all trailer hitch locks are universal and some will only fit common hitch sizes. The most common is either 2 or 2 5/16 inch couplers but its crucial that you check the size of your hitch before purchasing.
On top of the hitch size, be sure to check that the design of the lock you choose will not get in the way. You will want it to be securely locked in position without having to be adjusted to avoid other objects.
Additional Methods To Prevent Theft
Making the thieves job harder in the first place will results in them avoiding your trailer. Preventive methods to avoid trailer theft include:
- Parking in open areas if in public area
- Invest into a good trailer wheel lock
- Park near large objects if remote to make it harder
- Paint or leave distinctive marking on trailer
- Invest in tow hitch locks
- Install a GPS tracking device
Above are just 6 ways to prevent the theft of your trailer. Some owners may also extend their aftermarket car alarm to also protect the trailer.
However, the main steps listed will almost certainly make a thief think twice before attempting to steal your trailer.
Of course, if a thief has lots of time to steal something, they will be able to remove anything. Some tow hitches have a design flaw where they get a long pinch bar between the lock coupler and tow ball and then use lots of force. However, this will make a lot of noise and take time, which you should be able to hear/see.
Using a coupler lock to secure your trailer with potentially an expensive load on is a worthwhile exercise. The coupler lock that you choose is dependent upon your budget but even with the cheapest coupler lock, it is a deterrent to put anyone off stealing your trailer. Most criminals will just want to hitch it up and make their getaway.
All of our recommendations will secure your trailer and put off any criminal. If the load on your trailer is expensive, this should reflect the price of hitch lock you purchase.
