Have owned a Fabia MK 1, 2 and now a MK3 estate, have been satisfied with the car in general but now todasy found a major flaw with the MK3 locking system, went out to the car, unlocked all doors 2 button pushes,got in the car shut the drivers door   just before going to press the Ign/start button i had forgotten something from the house, left the key fob in the front containter by gearstick as normal got out of the car shut the drivers door as it was raining a bit  and went into the house to get my phone, when I went back out to the car THE CAR WAS LOCKED AND KEYS STILL INSIDE, I did have a spare fob in the house so was able to get in the car but surely the car should not self lock once you have opened the drivers door and then shut it again without the car locking itself without turning ingnition on or leaving fob in the car, I also noticed this happened with the hatch once before, unlocked the hatch but left key in the boot area shut the hatch and the car locked trapping key fob in the boot though ok  both other models never did this once it was unlocked it stayed unlocked until you pressed the fob again, suppose it's another idiot design improvement that you can lock your keys in the car easier than before, it makes me wonder what clown idea they will come up with next

Possibly a button on the key fob which if inadvertently pressed (for example by carrying the fob in a trouser pocket) will result in all the windows opening... 

No problems with the buttons sticking or being pressed key fob was just placed in the car as normal, it also happens when car has been running, prees stop button , ingnition off leave key fob in the car get out shut the door a few seconds later car locks, only way back in is by preesing unlock on spare key fob,  both remotoes have new batteries fitted car does not lock if drivers door is open but if you close the drivers door and leave passenger side open the car locks on it's own so it seems the main control in drivers door is playing up, the car is just still under warranty so dealers will be getting a call in a few days to sort it out

Ha here we go have now sorted this issue out no thanks to dealership all I could get off them you'l have to book it in about 3 weeks time, anyway it seems that when i went out to the car i used the spare key fob and althought it unlocked the car and let it start and stop again the car was locking itself as it was confused with the spare remote, when i used the normal set of keys and fob the car was also confused with this fob as well, in the end had to lock the car as normal go into the house remove the battery from the fobs wait 5mins then put the battery back in go to the car unlock the door lock it again then unlock the door get in shut the door turn ignition on, turn it off then turn it back on hold the key fob just to the right of the steering wheel and press the lock button, heard a loud bleep from the dash and now everthing is working ok again, this information came via a mate in an independant garage Skoda dealers might know about this but won't tell you cause they can swindle money out of you by saying there was a fault but warranty does not cover this issue
