KESSY on FR?

[Tell]

Holding your hand on the surface of the closing sensor will also close the windows and the roof.

Not totally true. You have to have convenience closing check marked for that on the infotainment. You can turn that off. A long press or hold is achieved by that.

Many of the issues of dropped windows originate from male tight pants so they sit on the sofa at home and wonder why when they go out to the car the windows are down. Solution to that is to toggle convenience closing to off. Well known Ateca issue. Should find that in the Leon 4 manual, see

"In the infotainment system different settings
can be adjusted using the function button 
> Exterior > Windows> Convenience open-
ing."

The sunroof / panoramic roof did also work like that but after a US accident with a trapped head (think someone got killed), VAG disabled that function although can be turned back on with VCDS with the risks. I doubt that if you can get a head in the roof of a Leon 4, VAG will allow central closing of the roof from the outside. Unless they have decided they can mitigate from legal action by a weaker motor.

The function is popular in the heat of Europe where you can open up and closing everything as you approach or leave the cat.

Taking this argumentation, it can be said that each option is not totally true


You can also read in the manual:

If the roof or the roller shutter meets any resistance or an obstacle when closing, it will reopen immediately.

Something must have gone wrong that there was an accident.

On the accident evident that VAG panoramic roofs didn't have the safety feature in then. Can you remotely now close the roof ?. It was this function that was disabled although the manual at the time showed it was possible. Good to know whether standing outside a Leon 4 you can now close the roof as well or whether the manual says one thing and it does something else.

On the first good to know you can turn convenience opening off to stop all those false openings that people report on boards since they keep their keys in trouser pockets at home and squeeze on them . That are kept away from the front door so car thieves can't use their Kessy reading devices on them. Personally I keep my keys not in my clothes. Shoulder bag I slip on, kept in the coatroom which is deep in the house. Those guys that lounge on the sofa with keys are open to car theft .

I wanted very much, but I did not order a panoramic roof. Due to less noises inside. Now I am happy because I can see that there are monthly delays in orders with a roof.
There are many inconsistencies in the manual, so I would not be surprised that it is as you write.

As for the keys, full agreement. It's stupid to sit on the couch with your keys.
Again, I will refer to the unfortunate instruction, which says that the key has a motion sensor and if it lies motionless for a while, it is impossible to open the car with it.

TIP: Aluminum foil is enough to block the key signal.

I got a decorative antiques pewter snuff box passed down I'll press into service when required during a holiday (always thought it was for keeping human ashes in ). Think the partners spare keys go in an old tobacco tin.

If you live in a high crime area or pass thru them you have to think about these things. In the main don't keep the keeps in the hall. Kent police issued some distance parameters once that the devices work over.

It's not a problem at home. Outside the house in a hihg crime area, it is enough for me to know that by touching the sensor and then pressing the button on the remote control, we turn off the keyless access until the next opening of the vehicle with the button on the key.

I think you may be using the incorrect sequence to temporarily disable keyless access. On my VW which works the same as it does on Seats, you need to press the ‘lock‘ button on the key fob first and then touch the locking sensor on the door handle. If the sensor it touched first, followed by pressing the ‘lock‘ button on the key fob, keyless access isn’t disabled and it’s possible on my VW to open the car by just making contact with the ‘unlock’ sensor on the door handle - assume this is also the case with Seat‘s keyless access system.

Below is the section from the mk4 Leon owner’s manual on temporarily disabling keyless access. It does state the locking button on the key fob is the first action, followed by touching the locking sensor (third point below);

‘Keyless Access temporary disconnection function

You can deactivate the vehicle's Keyless Access unlocking for one locking and unlocking cycle.

• Move the gear lever to position P (if the vehicle has automatic gearbox), since otherwise the vehicle cannot be locked.
• Close the door.
• Push the central locking button on the remote control and touch the locking sensor surface of the driver door handle within the following 5 seconds. Do not grasp the door handle; otherwise the vehicle will not unlock. Deactivation is also possible if the vehicle is locked through the driver’s door lock.
• To check that the function has been deactivated, wait at least 10 seconds, grip and pull on the door handle. The door should not open.’

• Push the central locking button on the remote control and touch the locking sensor surface of the driver door handle within the following 5 seconds.

I probably typing the wrong sequence, I haven't tested this function yet. And I would certainly check if they work properly after the first use.
But thanks for the correction, other readers will not be misled.

I withdrew the like .

I guess these might be new Kessy features post 2020 make over or undocumented ones of pre. Always good to test.

Last days KESSY stopped working for me. Lock works, but not unlock.
Changed the battery in the key without any luck.

 

[Tell]

That sounds like a defect in Kessy if you are using your hand on the lock and unlock motions on the door handle, it's a defect in the car. If the buttons try your spare key, if that doesn't work it's in the car.

 

[Swedemike]

Same for me, below 0 centigrade unlocking doesn’t work. If the handle is little wet or have some snow makes it worse.
-10 and locking stops working too.
this car have so many problems…

Has the same things and now noone wants to deal with it- they saying they dont have information yet how to fix it and there is nothing they can do..

 

[Tell]

Troubling. I guess this is a new Kessy issue specific to the platform and there isn't a long history. If so you would expect to have come across it pre 2020 models. Anyone ?.

 

[mackan73]

The spare key does not work either.
The one year service is in a couple of weeks. Then they also will troubleshoot some other issues.
So I guess I need to add KESSY to the list of issues...

There have been Kessy issues reported on the board with the Leon 4 a while back. They didn't seem to be related to cold weather thou which we don't really get in the UK. I get the impression they were software issues which subsequently got fixed. The door left or right was going to sleep. As described at the time it sounded like the battery saving feature in Kessy that puts to sleep one side of the car, left door handle in a right hand drive car, to save the battery had been set up on the wrong side for RHD delivery. Drivers couldn't get in. Sleep mode shouldn't be activated on all doors if the battery is deemed to be getting low. You might be experiencing that one with the cold weather causing poor battery performance.... just a thought. I don't think this one has come up on UK cars recently but I might be proved wrong. Those people with the issue had it fixed.

Yes, I had that problem when the car was new.
It was fixed and has worked until now.

 

[Swedemike]

Same here

Not that then.

The manual says that KESSY deactivates when it detects too much activity on the handle (e.g. a branch hitting the handle in the wind).
For example, at a car wash, water can open and close my car. So I suspect that the same happens during rain/snow, but due to the lack of a key near the car, the car does not open, but the activity on the handle is registered - this causes its deactivation.
