How to Lock Your Cooler

The last thing you want to worry about when you’re having a blast on your annual camping trip, is how to lock your cooler securely. 

Nothing ruins a trip faster than worrying about your important cargo, that’s why we suggest having a cooler lock with you at all times. 

How to Lock Your Cooler so it Stays Secure and Safe

  1. Start with a sturdy padlock and keys that can handle tampering.
  2. Check the corner of your cooler, there should be a half an inch wide hole going through the lid and body. 
  3. Place the neck through the cooler’s hole and make sure you hear a click as your padlock locks tightly. 

3 Best Cooler Locks That Can Even Keep Bears Away

1. YETI Bear Proof Padlocks

Some version of the padlock has been in use possibly for the past 4,000 years, that’s because it’s still the most effective way to lock up your belongings and keep them safe. 

The YETI Bear Proof lock is a crowd favorite, it has been tested against real bears and proven that no matter how hard they try they cannot break them.

YETI’s padlocks come in a set of two, with two identical keys as well. This is perfect if you want one to lock the cooler shut, while the other locks the cooler to a tree or truck.

The most important thing to remember when using a padlock, is to keep the key somewhere safe. These sturdy locks are made to be tamper proof, so if you lose the keys it will be impossible to open the lock again.

What I Like

  • It’s very affordable for a set of two
  • It lasts several years without rust or dents
  • It’s easy to use

What I Don’t Like

  • There isn’t a place to put the keys while the cooler is locked
  • It’s heavy and bulky to carry around

The Verdict

The bear proof padlock keeps your cooler securely locked and protected from bears. If a bear gets into the food in your cooler the situation can become dangerous because other bears will also come.

Keeping your cooler locked is very important while camping because wild animals can become dangerous if they find your food. The bear proof padlock ensures that your cooler will stay sealed shut until the key has opened it.

This will keep your belongings and your family safe. If a bear does try to open the cooler it won’t be successful against the stainless steel lock, and will move on quickly.

The classic padlock is the best value for your money, a set of two only costs $30 and will last several years.

2. Python Cable Lock

This six foot long cable has many different ways you can use it and is the must have accessory for any camping trip. 

If you don’t have a padlock on hand this cable will replace it perfectly. Simply push the cable through the cooler’s lock hole, then lock the device using the key. 

The benefit of using the Python Cable Lock is that it is flexible and adjustable. Meaning, you can cinch the cable as tightly as you’d like for a super tight grip on your cooler. 

This makes it impossible for thieves to pry it open or wiggle it free. You can unlock the device by inserting the key and turning it to the right. 

What I Like

  • It’s very flexible and lightweight to carry around
  • The adjustable strap allows you to secure your cooler to the max
  • It can also be used to tie the cooler to a truck bed or tree

What I Don’t Like

  • The vinyl outer casing can wear down quickly with frequent usage
  • It can be difficult to organize the six-foot long strap while packing

The Verdict

The Python cable is the best budget option, for less than $15 you can use this tool to lock up not only your cooler but also bicycles, lawn mowers, power tools, etc.

If you’re worried about locking up your cooler and keeping the contents safe, then this device is a perfect solution.

Not only does it fit in all cooler lock holes, but thanks to the six-foot long cable it can lock your cooler and you can wrap it around a nearby tree as well. This will ensure that thieves can’t open the cooler, or steal it entirely.

If you’ve invested in a high quality cooler then making sure it doesn’t get stolen is the first priority, it’s easy to replace any snacks inside but replacing an entire cooler is more difficult.

For maximum security, slide the cable through the lock holes then wrap it around a nearby tree or heavy object. After locking it you’re all set, you can hike for hours and your cooler will stay safe.

Push the pin up through the bottom of the cooler lock hole, once it’s in place lock the lid on top with the key, and you’re all set.

What I Don’t Like

When to Use a Cooler Lock (and When Not To)

Deciding when to use a cooler lock is very important for the safety of your camping trip or day at the beach. 

Whether you’re preventing theft from the people around you, or just trying to keep your cooler shut from wild animals, knowing when to lock your cooler is a priority. 

Be sure to always lock your cooler: 

  • If you’re leaving it unattended for a long period of time
  • If you’re swimming in the ocean far away
  • If there’s any prepared food inside that animals can smell (i.e. sandwich, chips, nuts, etc)
  • If you’ve put any valuable belongings inside for safe keeping
  • If you’re are transporting the cooler in a vehicle or truck bed

Keep in mind that bears can smell food from over a mile away, so simply closing the lid of the cooler is not enough to protect the contents. Always lock your cooler when you are not using it.

That being said, it’s not necessary to lock your cooler if there are several people nearby and it’s frequently being opened. As a rule of thumb, try to lock it whenever you’re transporting it, far away from it, or not using it. All other times you’re free to leave it unlocked.

Lock It Up

While all three lock options are great, the best one of all is the Bear Proof Padlock

Not only is it the best deal economically, but it is the easiest to use and lasts for several years.
