Hi Michail I had a very simular problem as you about 4 months ago and fitter who works on my car cured it with no charge?? This is what he done==== Key in ignition and on drop window drivers door. stand out-side the car with the door closed ignition still on put hand into car and work the small locking lever thats just above the inside door handle in and out a few times and if its really stiff squirt some WD40 into the handle and also the lock .?? work it again untill its free .?? Turn ignition off so it resets --window up and retry the locks with the Fob.?? He said if this dos'nt work its the door lock at fault .?? I hope this Helps. Frank
