Quick answer
Many vehicles open all the windows when you press and hold the unlock button on the key fob, and some close them when you hold lock. The feature varies by make, so check your owner’s manual for the exact button and hold time. To turn it off, look in the vehicle settings or ask the dealer.
How to roll down windows with a key fob
On many vehicles, pressing and holding the unlock button on the key fob lowers all the windows, and holding the lock button raises them again. The feature is meant to vent the cabin on a hot day before you get in. The exact button, the hold time, and whether the sunroof opens too all vary by make, so the owner’s manual is the source for your vehicle.
The feature works through the body control module, which interprets the fob’s signal and runs the windows. Some vehicles need the feature enabled in a settings menu, and some do not offer it at all. If holding unlock does nothing, the vehicle may not support it, or it may be turned off in the settings.
Windows that roll down by themselves are usually this feature triggered by accident. A key fob button held down in a pocket or purse can lower all the windows without the driver noticing, which is why a window is sometimes open when you return to the car.
Key fob window myths
Every car can roll down the windows from the fob.
The feature varies by make and is not universal. Some vehicles support it, some need it enabled in settings, and some do not offer it. The owner’s manual confirms whether yours does.
Rolling the windows down from the fob means the car is unlocked.
The windows can open while the doors stay locked, depending on the vehicle. Check your manual for how your system behaves.
You can add the feature to any car with a new fob.
The feature depends on the body control module and the vehicle’s software, not just the fob. A vehicle that does not support it cannot gain it by changing the remote.
