I have a y reg Punto 1200 and both the driver and passenger locks have gone and so gas my fob. The car isn't worth much but new locks will cost me about 300 quid fitted. Can I get locks from a breakers yard or do i have to go to a dealer? If so, does anyone know any good breakers in north London? Thanks

Yes. Of course, you need at least one key, too, and the codebox (assuming your car is Mk1 Punto, without the code 2 mark on the key).

if your key starts the car fine then you can just replace the door locks and have 2 keys..
