The other day this happened

• Touching the door handle didn't unlock car
• Touching boot handle didn't unlock either
• The remote key fob buttons did nothing
• Swapped the fob battery for a fresh one, no change.
• Tried the spares, i.e. all three fobs, same problem
• Got the multimeter out, all batteries were full
• The 12V battery also fine (it was renewed/upgraded in August)

 

So I removed the key cover for the driver's door and unlocked the door manually.

The alarm sounds so I look like a car thief while fiddling around the ignition, then I was able to start engine by pressing the start button with the fob.

Went for a drive - electrics seemed normal but Start/stop did not kick in when expected (with aircon off after a drive).

Also the other doors were not automatically unlocked. Had to press the lock button on the console to open the boot.

 

After a few hours it fixed itself.

3 days later it happened again. After a few hours it fixed itself again.

 

It seems from other posts a damaged fob is often the cause, but I can't see all three fobs developing the same fault at once.

Anyone had this?  I've got a few months left on my 'All-in' warranty but I haven't read the smallprint on this yet.

 

 

I have a MY19 Octavia estate and had all sorts of strange things happen to my doors, locking/not unlocking/alarms going off, seemed to have a link to whether it had been raining or not. After trying to understand the problem I got a main dealer in France (we were on holiday) to check for fault codes. He smiled when I explained the problem and took less than five minutes to identify the problem. It seems it is a well known problem with the front doors electronics The only solution is replacement. UK dealer who fixed the problem, for £400, more or less admitted it was a known issue.  I was 4 weeks out of an extended warranty!  

Interesting.

 

Well today it's behaving differently. The main fob once again failed to do anything, but the spares worked fine!  So it's currently looking like a faulty fob. I wonder what tomorrow brings. 

 

If the door needs replacing I need to get that proven before the warranty runs out.

I would suggest there might be interference that is stopping the KESSY system from working properly.  They operate in the 120 to 135 KHz frequency band and if all three stop working, then its going to be interference. 

Try parking your car in a slightly difference location and see if the problem still exists.  Then try and figure out the source of the interference.  You can look up the guide to frequency interference at OFCOM's website: https://static.ofcom.org.uk/static/spectrum/fat.html

It's now consistently behaving like only the main fob is broken and the spares are fine.  So I've arranged for Skoda to sort it under warranty.

@CheersDrive - what did Shoda do under warranty to sort the key fob problem? I have a similar problem - one fob opens all the doors using KESSY, the other fob only opens the front door you are adjacent to.

Thanks

That's easy.  If you go into Profiles, you will find that the individual keys fobs are configured differently.  One opens up all doors, one only opens up the front door....

 

So - take the key that only opens up the front door, unlock it, get in - go to the MIB system, and go to Vehicle, settings, keys and fobs and set it to unlock ALL doors.  Problem solved.

Thanks. Wouldn't it be great if Skoda made that clear in the owner's manual...

FWIW they found no faults stored in the vehicle so they replaced all batteries and re-coded all fobs, and it's been fine since.
