You still have a wiring issue, you will need to track it down.

There is a earth fault somewhere. try to check your earths on the lights should be a green cable connected to the body of the car near the lights sometimes found inside behind the lights.

your mechanic has only given you part of a possible solution...lock the car with the key and hold over for 30 secs then take key out,wait 30 secs then unlock/hold key over for 30 secs,the windows may go down. then use the remote to lock car holding down the button for 30 secs..... this resets the system

You have a bad stop light switch. There is a recall on it.

You have the wrong KEY if it won't turn any locks.
You can use the KEY fob from another Passat.
The one you have was most likey not the original
and the car was reprogrammed to except that FOB.

The Fuse panel Is inside the DRIVES side.
Open the Driver door. Look at the side of the DAShboard.

Did AAA jump your battery? if not hook a comercial battery charger up to; or, remove recharge; your battery: this should release the locks then: you have either short draining your battery or, a bad alternator or, battery

Driver door module is where to look also a broken or corroded wire and if you use your key to punch in the door code then the key pad has a hole in it or it just went bad it's not the remote control also check the master door lock switch for corrosion at the pins and the plugs same with the driver door module
