Never worry about your cooler again with the strongest cooler lock on the market!

Constructed of 304 stainless steel to be as durable as possible, your cooler will be kept safe. IT ONLY TAKES ONE LOCK! Normal cable locks can be cut easily with bolt cutters – not the DENY Lock.

The easy-to-install cooler locking system protects your coolers from theft by locking them firmly into place. Whether on your truck, boat or ATV, DENY’s sturdy IronFist™ base easily mounts onto any vehicle and the rugged StiffArm™ locking shackle prevents your cooler from going anywhere!

DENY Locks have been thoroughly tested in military-grade facilities and intense real-life situations in order to ensure that thieves cannot overcome the IronFist Base™ and StiffArm™ Locking Bar.  The locks are able to withstand everything from harsh weather to off-road vibrations, meaning that your cooler will stay put during even the most intense situations.

Lock it or lose it!

    I received an early prototype. I’ve had it mounted in the bed of my truck along with the Yeti cooler for about 4 months now. The cooler is still there after 4 months! It wouldn’t have made it a week without the Deny lock. Excellent product that keeps your Yeti safe in public and is very easy to remove and reinstall the chest from the lock. Thanks Jake and team!

    Product is very simple to install, and I have never seen anything more stout. I have a flatbed truck and everyone sees my cooler on the back buckled down with DENY so I know they won’t even try and take it. Keeps my cooler in place so I can get a drink when I need one!

    I have a flatbed truck with three Yeti coolers mounted in it…This is a huge target for “cooler thieves”!! I used to lock them with cable locks, which I guess is better than nothing, but I always worried. After meeting Jake at a show in AZ I bough three Deny locks…now I can rest assured that every time I have to leave my truck the Yeti’s will,still be there when I get back. Thank you Jake!’

    Great product. Well made and solved a major problem for myself. I was able to use it for double duty in securing my Kayak on my truck rack with running the stiff arm through a pewag chain. Can’t recommend this enough if you spend time outdoors and love to have your cooler and ice ready at all times!

    I just got back from a month long trip with my expensive Bison cooler in my boat. It was secured by my new Deny lock. It held firm the entire time and I’m now confident that no one is going to mess with my cooler while I’m in a restaurant or hotel. This is a great lock. Never seen anything like it.

    I have been using my Deny LOCK and Yeti 45 on my flatbed of my truck for a month now. Plenty of bumpy roads hauling mules into the backcountry. Cooler is locked down and doesn’t move. Get out and go, no need to move the cooler from the back of the truck to the inside of the stock trailer. Great Product!!

    This lock is all that and MORE! After having two coolers stolen with other locks that said they provided protection, we found the DENY lock system and were hooked from the first time we put it on! My husband works in the oilfield and a cooler is a must. Having it inside the cab is not an option, due to all the tools needed for his job. The DENY lock has taken all our worries away. Such an amazing product and even better customer service! Timely and well informed responses and they even went out of their way to make sure our lock was outfitted correctly. My husband has now told all his friends about this product and will continue to do so to everyone he meets! Thank you for making our lives a lot less stressful!
