Ventlock Tailgate Locks

Ventlock Tailgate Locks


$19.99 - $35.99

There are many times at trials, and during rest stops on the way to and from trials, that is convenient to leave your dogs in the car. But until now, for the security of your dogs and everything else in your vehicle, the only ventilation you could provide for them is leaving the windows cracked open. The Ventlock Tailgate Lock allows more ventilation into your vehicle than just having the windows open, while at the same time allowing you to lock your vehicle in the normal way, using either your key or keyless locking device.

The Ventlock works by fixing your rear door or tailgate in a semi-open position. Combined with a front window open just an inch or two, you'll have free-flowing air just where the dogs need it most—on their noses at the back of the vehicle. It takes only 10 seconds to install or remove the Ventlock; no tools are required.

The Ventlocks is made from steel and then coated with a tough polymer-based epoxy polyester finish or durable nickel coating. It is incredibly strong and made to withstand a lifetime of hard use. 

Will the Ventlock Fit My Vehicle?

The Ventlock fits 99% of estate cars, hatchbacks, vans, and 4-wheel drive vehicles fitted with a rear door. The Ventlock will fit your vehicle if it has a catch or post simliar to anything shown in these photos:

It is suitable for use on models by the following manufacturers: Audi, Acura, Buick, BMW, Cadillac, Chrysler, Chevrolet, Citroen, Daewoo, Diahatsu, Dodge, Fiat, Ford, GMC, Honda, Hyundai, Infiniti, Isuzu, Jeep, Kia, Lada, Lancia, Land Rover, Lexus, Lincoln, Mazda, Mercedes, Mercury, Mitsubishi, Nissan, Oldsmobile, Opel, Peugeot, Plymouth, Pontiac, Proton, Renault (Laguna model only), Rover, Saab, Saturn, Seat, Skoda, Ssangyong, Subaru, Suzuki, Talbot, Toyota, Vauxhual, Volkswagen, Volvo, Yugo.

We are frequently asked whether the Ventlock will work with your alarm system. It works on the majority of manufacturer-installed central locking and alarm systems, which means that you can use the Ventlock and still lock and alarm the car. However, occasionally, some vehicles (usually those fitted with alarms after the car has been purchased) have sensors that do not allow you to leave any doors open. In this case, you would lock the car with the central locking and the Ventlock in place, but not set the alarm.

Security Note: On some vehicles, such as full-size vans, there may be a manual latch on the rear doors to open the vehicle that will be accessible with the Ventlock in place. In this event, be aware that the Ventlock will not keep your vehicle secure from others entering it. However, if you frequently crate your dogs in your car at trials and don't required locked security, you may still find the Ventlock useful for limiting what your dog sees. If you need locked security, however, you need to ensure that installing a Ventlock does not allow access to any release catches, buttons, or handles from outside the vehicle.

It's important to note that unlocking your car will only unlock the Ventlock, it will not release it from the latch. You must lift/open your door handle to release the Ventlock from its position.

 Safety Notes:

  • As dog owners ourselves, we feel duty-bound to say that whatever method of ventilation or protection against sunlight you use for your dogs when they are in a parked car, there can be no substitute for checking your dog on a regular basis—even if they are in the shade. Do not leave pets unattended in a parked vehicle in direct sunlight even with your windows open.
  • The Ventlock is not suitable for use when the vehicle is moving or when the engine is running.

If the Ventlock fits your vehicle, then all the sizes are available to you. There are no special sizes for different cars. If one fits, they will all fit. The choice comes down to how far open you want your rear door or hatchback to be. Ask yourself these questions before you make a decision:

  • Are your dogs in a secure crate? If they are, you can have as big a gap with as much ventilation as you like.
  • If your dogs are not in a secure crate, then you need to choose a Ventlock that will not let your dog get out through the opening in your rear door or hatchback.
  • If you want your vehicle to be secure, then you need to make sure the size of Ventlock you select does not allow access to any release catches, buttons, or handles from outside the vehicle.

A simple test is to put your dogs in your vehicle and then open the back door or tailgate to create the size opening you are happy with and then measure that space and order accordingly.

Below are some other guidelines that may help you choose. Many people end up buying two different sizes so they have flexibility for different situations; for example, getting a 9" and 18" Ventlock is a popular choice. 

  • 4" – Ideal for uncrated small dogs or in cooler weather. When fitted to the tailgate or one of the rear doors of your vehicle, the amount of ventilation provided by the 4" Ventlock is equal to that achieved by leaving all the windows of the vehicle one-third open. A good choice for the rear door of 4-wheel drive vehicles.
  • 6" – Useful for uncrated larger dogs left for relatively short periods of time, such as a trip to the grocery store where leaving a window open might attract the attention of the opportunist thief. Along with the 4" model it is also an excellent choice for the rear door of 4-wheel drive vehicles.
  • 9" – One of our most popular sizes. Good for uncrated medium to large breeds that will be unable to get through a 9" gap. Provides quite a bit more ventilation than the 4" or 6" Ventlock.
  • 12" – This is probably the largest model Ventlock that you should use if you are not leaving your dogs in crates in the car. Circulates lots of air.
  • 18" – For those of you who keep your dogs in a secure crate in the vehicle, both the 18" and the 24" Ventlock provide the ultimate way to give your dogs access to free flowing air but have the peace of mind knowing that the tailgate cannot be opened or closed without your consent.
  • 24" – This is the perfect choice for crated dogs either in conjunction with a reflective space blanket on a hot day or on wet and windy days when there is a real possibility the tailgate may be blown shut.

It takes the average person around 10 seconds to fit or remove a ventlock; no tools are required. Here's how to do it:

  • Unwind the threaded hook a few turns and place it over the post or through the catch inside the car.
  • Gently screw on the Ventlock until it is firm but not overly tight.
  • Close the door by pushing the latch mechanism onto the free end of the Ventlock.
  • The vehicle can now be locked in the normal way using the key or central locking.

To remove the Ventlock, unlock the vehicle in the normal way and simply lift the handle or turn the key and gently pull open the door. The Ventlock will automatically be released from the door latch.

IMPORTANT: It's important to note that unlocking your car will only unlock the Ventlock, it will not release it from the latch. You must lift/open your door handle to release the Ventlock from its position—unlock AND unlatch! We highly recommend watching the product demonstration video.

Not as secure as I'd like
My old hatch lock got lost while the car was at the repair shop, and is no longer available. This looked like an acceptable alternative. It works okay, but the hook is a bit clumsy, and too short to be truly secure. Will have to fiddle with it and see if I can make it work better. (Car is a 2011 Chevy HHR.)
Comment from Clean Run We're not sure what you mean when you say that it's too short to be truly secure. The shorter the Ventlock, the more secure as the hatch cannot be opened as much. If you can send a photo to so we can see how it's fitting, we'll be happy to advise you. It may be that a different size would work better with your vehicle.

Honda Fit -- Can't find a way to Use this product
Perhaps I am just too thick to see it--but I found I could not find a way to use the Ventlock with the rear hatch door of my 2007 Honda Fit. This is disappointing, as it is claimed that the Ventlock will indeed work with Honda vehicles. Sorry, but it seems to me that the Fit is an exception to this claim--unless anybody out there with the same vehicle can enlighten me! When it comes time to replace this car, I will be taking the Ventlock with me when shopping for a car--so that I can ensure that it will work with whatever I next choose...
Comment from Clean Run Sorry that you're having difficulty with the Ventlock. If you look at the Ventlock product page, click on the second thumbnail image to see photos of the catches and posts the Ventlock works with. Is the catch on your rear hatch door anything like any of those? We don't have every car available to us to test, but if you can send photos to customer service at, we're happy to help you get this sorted out!

Love my ventlock!
I love my Ventlock! I use it often while traveling and at trials. I love being able to provide the nice airflow but still have the vehicle securely locked when I stop for a short pitstop while traveling.
