Have one set of keys for a Crossfire, wanting to get another programmed and cut, doesn’t seem to be anyone able to do it in Western Australia, any advice, cheers

 

There are two well known places here in the U.S. They are very reliable and you can email them for information or they might know of a place in Australia that can help you.
There is needswings.com and themercedesswapshop.com both places are great and have great experience with the keys for our cars.
Good luck to you!
