Problem is somewhere between your battery and the main fuse panel. Either one of main fuses blew or some wire fell of the panel terminal. Being that the battery has power, the headlights and radio work; this means that power is making it to your panel itself. But from the panel to SOME of the main components, it's not. So problem is in the fuse panel. Check your car manual for multiple panels. Sometimes the larger fuses and relays are in one panel, and the other accessory fuses are in another panel. Your problem would definitely be one of the bigger fuses, as the starter alone is usually on a 30amp.
Are your Brake Lights working, as there is a Brake light switch that goes flaky, then move the Transmission selector to Neutral and try to start it It sounds as if your neutral/park interlock is possibly wonky.
Have someone hold your key in the START position while you tap on the starter. You may have worn bushings if you hear any clicking or the car starts up. Also check your all your fuses and relays to make sure none have blown.
if your car is a mk4 body style, check the drivers door to see if the red light is blinking. if it is, the factory alarm is acting up. this alarm has a starter kill built into it. you have to turn off the alarm. try the keyhole in the vw symbol on the trunk. if the light doesnt blink at all, you have a blown interior light fuse. i think its fuse number 14. fix the alarm problem, and it will take care of the no start.
The lock barrel probably has just gummed up. It's unlikely that you have a bent pin. Try spraying WD40 into the keyhole. This works in 99% of cases. If that doesn;t work then a locksmith will cost you about ?60 + the cost of a new barrel. You can replace the barrel on a PVC door your self if you are confident enough. I'm assuming that you have the normal PVC door lock which is a Yale type key combined with lever handles. Look at the edge of the door near where the lock's tonge sticks out. You'll see a single cross-head screw. This holds the barrel in place. Make sure that all is in the unlocked position. Take off the handles and eustucian plate from the inside of the door. Remove (carefully) the screw I mentioned. Pull out the barrel. Take your new barrel and replace by reversing the above procedure.
