Peugeot 806 - how can i lock my car when neither the key or keyfob work?

Try resetting th ecode. To do this use the spare key and put in ignition and turn it 1 click to auxilliary. Then point click the remote button about 6 inches from the roof sensor. switch off and try the remote. I have just reset mine that way. My key spins in lock too.
