Open and Close the Windows From the Key Fob

Last updated: June 10, 2026

The SEAT Leon (Mk4/KL, 2020–Present) shares the VW Group party trick that lets you open all four windows — and the panoramic sunroof, where fitted — from the key fob. On a sweltering day you can stand a couple of metres from the car, hold one button and vent the cabin before you get in; spot a window left down with rain coming and you hold the other button to wind everything shut from a distance. SEAT calls this convenience opening and closing (the comfort window function), and most owners never realise their key can do it.

What convenience opening and closing does

Holding the remote’s unlock button rolls all the windows down together; holding lock winds them all back up. On Leons with the panoramic roof, the sunroof opens during the unlock hold and closes on the lock hold. The glass moves only while you keep the button pressed, so you can stop at any height by releasing. The key needs to be near the car for it to respond.

How to open all the windows from the fob

1. Stand within a couple of metres of the Leon.
2. Press and hold the unlock button on the key.
3. Keep holding — all the windows wind down, and the sunroof opens if fitted.
4. Release as soon as they reach the level you want.

How to close all the windows from the fob

1. Stand next to the car within remote range.
2. Press and hold the lock button continuously.
3. The windows wind up and the sunroof closes while you hold.
4. Release once everything is shut.

How to enable it on the touchscreen

If holding the button does nothing, check the infotainment. In the vehicle settings look under the door/locking or open & close section for the convenience (comfort) window opening option and switch it on, choosing all windows where the menu offers a choice. With it enabled, the remote operates the windows as above.

If there is no such option, the feature is coded off at module level — common on base trims. A VAG diagnostic tool such as OBDeleven or VCDS activates the comfort opening and closing parameters in the convenience control unit, after which the menu toggle and remote buttons work.

The door-lock fallback

On Leons with a physical key barrel in the driver’s door, pull the emergency blade from the remote, remove the handle cap, insert the key and turn and hold toward unlock to lower the windows or toward lock to raise them. The convenience function must be enabled for this to work; keyless cars use the remote buttons instead.

Frequently Asked Questions

Why doesn’t holding unlock do anything on my Leon Mk4?

The convenience window option is probably switched off in the touchscreen, or coded off at module level. Enable it in the vehicle settings first; if there is no option, activate it with OBDeleven or VCDS in the convenience module.

Does the panoramic sunroof open too?

Yes, if your Leon has the panoramic roof. Holding unlock opens it with the windows; holding lock closes it.

It worked, then stopped — what happened?

Usually a window has lost its one-touch calibration after a flat or disconnected 12V battery. Re-initialise each window (hold the switch fully up until it stops, release, hold up again briefly, repeat down) and the remote function returns.

Can I open just the front windows?

The Leon Mk4 opens all the windows together with this function; there is no factory front/rear split like some Audi models offer.

How close do I need to be?

For safety use it within about two metres, so the remote stays in range and you can watch the glass. Releasing the button stops the windows instantly.

If a window won’t respond from either the door switch or the remote, or a convenience-system warning appears, the body control module has likely stored a fault code. You can decode it and see the likely cause at autodtcs.com.
