Can you get a new set of keys from your car dealership if you lost yours?

If I'm not mistaken, yes you can. They can take the vin number (or some other number) and have keys made that fit and work in your particular vehicle...it may cost you a lot though. I know it can be done with the new electronic "keys".

Yes but that is the most expensive option. A locksmith or hardware store with a key shop usually charges less for both chip and non-chip keys. Make spares so you are not stranded.

Yes, just give them your VIN# and they will get the codes tobmake a new set.

you can but expect to a hefty price like 180 bucks

For like £500

I don't think so.
