Are there master keys available for your make and model of car at the local dealerships?

no

You can get a master key from the web at www.lostcarkeys.co.uk/ Since most cars after 1999 have encoded car keys, it is very difficult and expensive to get new keys and switches changed on most cars. Hope this can help you.
