HELP PLEASE Skoda Octavia GLX TDI (1999) hatchback The lock-barrell on my drivers-side door has failed (faulty tumblers !). I have obtained a used replacement barrell and key from a Skoda breaker. Can anyone advise me how I should go about removing the existing faulty barrell and installing the replacement. Any help or advise anyone can offered would be very much appreciated K.G.
