Hi There
Bought a 2010 Hyundai Getz yesterday and it only came with one key. I rang hyundai and they quoted $380 for a new key (with buttons) and $110 to make it work with the car. So $490 for a key.
I've been googling and there doesn't seem to be an alternative. I asked the Mister Minute man and he said he can only do the ones without the button ($140) - but from what I've read it may not even start the car as Hyudnai seem to have to do something special to make the keys work.
Thanks
Get 2 buttonless keys made. Stick the key with buttons/fob under your dash. Buy the blanks from eBay.
