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 car in question was a Chevrolet Malibu. The owner’s manual was available and was dead wrong, which is, of course, the true source of the problem. The year, make and model in the U.S. has a back up slot in the center console.
It also uses a flip key, which suggested a spot like that is used in the Cruze (right) or first generation Volt. No such plug in spot exists in the Malibu in question.
A disturbing trend appeared in the recalls (2015) we tracked since our last newsletter. Six recalls were issued involving automated electronic systems, including safety systems directly and indirectly. And they simply got more troublesome through the course of the month.
Subaru 
First a word of caution concerning the Ford GT. Its latches are entirely electronic, the result being that, in the event of a power failure while inside the car, a back up plan is necessary. There is a strap on each pillar alongside each seat, as seen n the image to the right. Pull it to release the door.
In the Taurus, Expedition (before 2018) and Flex the Intelligent Access key slot is to the rear or the side of the console and points up. The key is slipped in vertically or horizontally depending on the slot’s shape, with the buttons facing out, as in the image shown. After inserting the key, use the Start / Stop ignition button and brake pedal to start your vehicle as usual. If it fails to start, turn the fob so that the buttons face back and try again. Once the vehicle is started, the key can be removed from the backup slot, if you wish.
In the updated (2018) Expedition, and (2025) Explorer (with bucket seats — see well below for column shift models) models the back up slot is in the front cup holder (Expedition) and rear cup holder (Explorer). There is a two-piece mat at the bottom, and the front piece needs to be pulled away. It is a loose fit and slips out easily. Drop the key fob into the slot with the buttons facing the back of the vehicle and start it as normal.
In Explorer and Fusion 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 (in the Explorer we had, the vehicle started with the buttons facing either direction) and the key ring up.
Transit
The new Ranger compact pick up also uses a cup holder, the rear one. Place the key fob in the cup holder making sure that it is centered and is parallel to the brake handle, as can be seen in the image at right. The truck can then be started by stepping on the brake and using the Start / Stop button as normal.
The Edge back up slot is inside the center console, but actually beneath the the front of the console (right). It is difficult to see, but it can be felt as raised tray just the right size for the remote control. Slip the remote onto the tray with the buttons up and press the Start / Stop button while stepping on the brake as normal.
Escape
In the 2018 Escape, the back up slot is found in the front cup holder. The bottom is marked with radiating lines meant to indicate radio waves. Remove anything that may be in the cup holder and set the fob inside, as shown in the image at right. Once it is placed, use the Start /Stop ignition button to start the vehicle while stepping on the brake as normal.
Bronco, Maverick, Transit (2024 and later)
/Stop ignition button to start the vehicle while stepping on the brake as normal.
The EcoSport, introduced in 2018, also uses a location in the front of the center console. Drop the fob into the slot with the key ring up and the buttons facing the back. After inserting the key fob, use the Start / Stop ignition button and brake pedal to start your vehicle as usual. And again, the key fob can be removed from the backup slot once the vehicle is started, if you wish.
Mustang, Fusion, Expedition
In 2024, Ford moved the Mustang back up start slot to the bottom of the center console. Remove the mat covering the bottom — as well as anything stored there — and place the fob in the fob-shaped depression with the buttons facing up.
Mustang Mach E
F-150, Explorer, F-150 Lightning
If the shifter is on the center console through 2016, the slot will be under the rubber mat in front of the shifter. Remove the mat and insert the Intelligent Access key with the buttons facing up.
In 2017, trucks with the shifter on the center console have the back up slot moved to one of the cup holders. Through 2020, the front cup holder is used, but it is moved to the rear cup holder starting in 2021. All Lightning models use the rear cup holder. Remove the mat at the bottom (see image) by pulling the tab and stand the key fob up in the slot, buttons forward. Then press the Start / Stop button while stepping on the brake as normal.
F-250
The compact Focus has five variations alone, with the Escape and C-Max sharing two of them and the Fiesta sharing one. The fifth Focus variation belongs to 2016 models only. All are located on the right side of the steering column near the windshield wiper lever. And see below for Fiesta and Focus models built after 2020 and not sold in North America.
If you see the transmitter symbol, which may have a key or tower in between the radiating lines, and you have a three button Intelligent Access key, slip the key into a small slot beneath the symbol, as shown.
If you have a five button Intelligent Access key, place the key against the transmitter symbol, as shown in the image, and start the vehicle. The vehicle will recognize the key, even if the key’s battery is dead. Use the Start / Stop ignition button and brake pedal to start your vehicle as usual.
If you see a cover, like the one shown above, there are two options. If a small slot or notch is visible, as seen in the image, pry off the cover using the mechanical key and insert the Intelligent Access key, as shown.
If the covering does not have a slot or notch to pry off the cover, which will include Fiesta models, simply hold the Intelligent Access key against the cover, similar to the five-button process shown above and as shown here, and start your vehicle using the Start / Stop ignition button and brake pedal as usual. The vehicle will recognize the key, even if the key’s battery is dead.
In 2016 and going forward, Ford made a change in the Focus. The back-up slot will be found at the bottom of the center console. It will appear as a depression in the floor of the console in roughly the shape of the key fob.
console storage compartment with the buttons facing up.
Fiesta and Focus models built after 2020 feature a small storage area in front of the shift lever on the center console. The area’s rubber mat must be removed, much like the pick up trucks with center console shifters seen earlier. There is even the mark of a key with lines radiating from it to point out the location (top arrow). Place the fob as shown (lower arrow) with the buttons up. Step on the brake and start the car using the Start / Stop ignition button as normal.
Finally, if you happen to have the GT model, the back up location is a storage tray at the front of the center console beneath its rubber mat, like the Fiesta and Focus above. Lift the mat and place the key fob with the buttons up, as shown in the image. Step on the brake and start the car using the Start / Stop ignition button as normal.
message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.
Does Your Owner’s Manual Have a Troubleshooting Guide?
How Deep Is Your Owner’s Manual?
We’ve done a couple of owner’s manual rants and got to thinking about where the average driver might look in their respective manual if they ran into trouble, specifically with dead or dying key fobs.
So, we examined a sampling of owner’s manuals from BMW and Mini, Fiat Chrysler, Ford, GM, including Buick, Chevrolet and Cadillac, Honda and Acura, Kia and Hyundai, Land Rover and Jaguar, Mazda, Mercedes Benz, Nissan and Infiniti, Subaru, Toyota and Lexus, Volkswagen and Audi and Volvo. And since we are adding this commentary, you can probably guess the results.
To Index or Not to Index
Next, we looked to see if there was an index to resort to. Several, BMW, Land Rover, and Ford, for instance, have no indexes at all. So if someone out there is from these companies, please consider adding that in. On the other hand, the indexes we did find were no help at all with dead key fobs.
The Honda and Acura chapters point to an issue with the key fob being weak. This may not be immediately obvious to the operator, but it would be a likely spot to check out if the car wasn’t responding.
Absolutely none of the other manufacturers point directly to the electronic keys in anything remotely like a troubleshooting chapter. To be clear, they all have the solutions shown, but the driver is left to contend with 400, 500 or 600 pages of information to get to what they need.
So for all of them, walk a mile in your customers shoes and try to think like someone who simply doesn’t understand what is wrong. Then make a Troubleshooting chapter and forget the clever titles like Handling the Unexpected or Volkswagens do it yourself chapter, which is where they keep breakdown assistance.
The closer your cars get to being rolling computers, the more relevant an actual Troubleshooting chapter will be to your customers.
