Hello, I recently purchased a Seat Leon 1 2005 1.9 TDI 5 doors. The remote control in the key did not work, so I opened mechanically all the time, recently I replaced the battery in the remote control, when I press the red LED is lit, but it still does not open or close, I think that the remote control simply decoded. I would like to do it myself at home and save a little, for all help I will be very grateful!
