You get 2 keys as standard. Your dealer should also give you 2 keyrings and if you're cheeky, ask them if they will give you a colour coded key cover. Always worth asking for freebies when you've handed them a decent sale!
Thanks Leon - are they 2 proper keyless & enter & go keys? Reason I ask is we have an Altea (bought it when it was 2 years old from a Seat dealer) and had one remote control to unlock the door key fob and the second was just an ignition key.
