I lost the key for my 2011 Hyundai Accent. Took my wife's key to a locksmith to make a copy and was told that Hyundai keys can only be duplicated at the dealer. That was the first sign of trouble. I knew instantly there would be price gouging involved as they effectively have no competition. I begrudgingly took the key into the Ajax Hyundai dealer and was absolutely floored when they told me the cost for a replacement key would be $200!! For the record, this isn't a remote key , it is a standard mechanical key (they claim it has a microchip inside it... but even if so, it doesn't perform any functions beyond a standard key). This is a blatant case of taking advantage of a customer's helpless situation by ridiculously overcharging them for what would otherwise be a very cheap item. I can't imagine the key costing them any more than $5.
I will never by a Hyundai vehicle ever again and if you can, I'd advise saving yourself the trouble and avoiding this dealership.
