a few electronic issues, hoping someone can help

Hey all



i bought an 08 laguna sports tourer



i have a few issues with it and i hope someone can help.



1 - the cd player does not accept cds, it spits them out after taking them in. its a 6 cd changer.



2 - keyless entry doesnt seem to work? renault have said the car defo has this feature. the dealer said it didnt. renault asked me what colour the badge was on the card and stated as it is chrome this proves it has it?



3 - today the drivers window stopped going down fully and automatically with one press. i need to keep pressing the button and it moves an inch or 2 each press. is this a common issue?



thanks for you time guys :d
