Who Opened the Windows?
Here, we discuss a feature found in cars from a number of manufacturers that catches people with their pants down. Or rather with their windows down. So, this is not about a fault or a system failure or a warning light, but about something working exactly as it is supposed to, but doing so seemingly at random on its own.
If you’ve ever walked out to your car and found all the windows open, this is the subject. Keyless start vehicles made by BMW and Mini, Honda and Acura, Ford and Lincoln, Maserati, Mercedes, Toyota and Lexus and Volkswagen Group, include what is called a convenience feature, which opens all the windows for ventilation when the unlock button is pressed and held. The sunroof will be open as well if there is one and the car unlocked.
Can it be Shut Down?
From what we’ve discovered only Mercedes and some vehicles made by the Volkswagen Group offer the option to close everything again using the lock button. The Honda we had for demonstration (below) did not.
So, what is causing the surprise window openings can be explained by accidental button presses. Whether carried in a bag or in a pocket, something pressing on the unlock button for an extended period can and will activate the feature, if the key fob is within 50 feet or so. Remember that while the fob’s keyless access can only operate within 18 to 24 inches of the vehicle’s door handle, the buttons on the key fob will work from a much greater distance.
For a fob carried in a pocket, preventing this may be a simple as turning the fob over on the key ring. The buttons will face the other way if your keys tend to rest in the pocket the same way each time.
If it is carried in a bag, the nature of keyless open and start can easily lead to the fob migrating to the bottom of the bag. Anything and everything sitting on top of the fob can and will activate the feature.
In this case, you might try using a device like a carabiner or snap hook. It can be hooked to a strap and still actually be closed into the bag. But it won’t work its way to the bottom. The devices come in many different sizes and colors so you can be a stylish as you’d like and they can be found online or at most hardware stores.
To finish the discussion of the functions of the actual convenience feature, the windows will stop short if the button is released, and will continue down if it is pressed and held again. Some vehicles require the unlock button to be pressed and released once before the convenience feature will work.
In Honda and Acura vehicles, the feature can also be activated by holding the mechanical key turned to the right in the key cylinder, but this will not happen accidently. Also, turning and holding the key back to the left will close the windows and sunroof.
The feature can be disabled in Ford, Lincoln, Toyota and Lexus vehicles, but you’ll need your dealer. In fact, the feature in a Toyota and Lexus must have first been activated in this way.
So, if ever you find your windows wide open one day, don’t panic — find a new way to carry your key fob.

The MKS is unique in using the glove box as the location for the backup slot. It is to the far right side under the glove box door, and may be difficult to reach. Slip the Intelligent Access key down into the slot with buttons facing out and with key ring up or out. See the image.
bit.
In 2018, the Navigator location is moved to the back wall inside the center console (right). It should look like a pocket anchored to the back wall. Slip the key fob in vertically with the buttons facing forward.
the front wall structure ( lower right). For this model, the key fob should be placed on its side with the buttons facing the back of the console.
In MKT, MKZ Hybrid (2013) and new (2017) Continental models, the slot is found near the Auxiliary, USB and power ports in the center console, like the one shown. The Intelligent Access key is slipped in with the buttons facing out and the key ring up (in one vehicle we tested, the vehicle started with the buttons facing either direction).
In the MKC and MKX (through 2015), the backup slot is to the front of center console, also found near the Auxiliary, USB and power ports, as shown. The Intelligent Access key is slipped in with the buttons facing out and the key ring up. The slot is impossible to see and you may want to feel for the ribbing at the bottom of the slot.
Nautilus, new in 2019, uses this location as well. There is a visible depression in the console’s floor the shape of the key fob. Place the fob in the depression with the buttons up and key ring end facing forward.
New in the 2014 MKZ and MKZ Hybrid the backup slot is hidden under one of the cup holders.
(IA) (remote control or ‘clicker’) key styles. Two of the key fobs use a sliding release on the back side to release the key. Two new key fobs use a push button to release the mechanical key, and one is much easier than the other to use. Another holds the key inside the fob itself and is really difficult to remove.
To release the mechanical key blade in your IA key fob, slide the release on the back of the transmitter and pull the blade out. You can now use the mechanical key to unlock the driver’s door.
(pull is straight up and off) to access the key blade. Its awkward and may need a little practice. That mechanical key can now be used to unlock the driver’s door.
To remove it, push the buttons on either side of the key fob.
It has a push button on the front of the mechanical key itself near the key ring space. Simply push the button and pull the mechanical key away from the IA key.
However, the 2017 Continental and 2020 Aviator bring a very new wrinkle into the mix. The key hole is hidden by a spring-loaded cover and is in a very different location. The key hole has been placed in the chrome molding beneath the driver’s door mirror and behind the imprinted words ‘Continental’ or ‘Aviator’. Simply insert the key and turn to unlock the car. The door will spring open. No word on how well the key hole cover will behave in icy weather.
In addition, the Navigator, updated in 2018, hides the keyhole in plain sight. The door handle is a single piece. The key hole is exposed by simply pulling the driver’s door handle away from the body of the car. It is seen angled outward at the back end of the handle. Insert the mechanical key and turn clockwise. Remove the key and release the handle. The door will open on the next pull. Note that the alarm will sound in a minute or so if the car is not started in time.
Finally, the new Nautilus model hides the key hole under a cap at the back of the driver’s door handle, which must be removed. To do this, insert the key blade into the slot on the bottom of the handle (right image, bottom arrow) and press up. While holding that upward pressure, move the cap rearward to release it. Gently remove the key while doing so. Yes, the effect is that of prying off a piece of your car but its OK and necessary!
Can Your Car Windows Open on Their Own??
Why Are My Windows Open?
