I wanted to say i got my keys for under 20usd shipped to my door. These are the high security keys uncut. The quality is very good.
I ordered these from ebay, not affiliated with the seller.
https://www.ebay.com/itm/253796501239I had both keys cut for 70$ by a local locksmith. He had to set his computerized machine to 1986s class to cut them as the 1980 showed regular keys. Not sure if my car had something weird or the people who made the machine were wrong. The keys work very well. I am looking forwards to disassembling the cylinder out the dash for a good cleaning and graphite lube.
Obviously not a cheap way to go, but i expected worse. I was prepared to scan the key the car came with and transport it to cad and mill out the keys on my cnc mill otherwise. Glad one of the local locksmiths got it done. He was surprised mercedes used high security keys in 1980.....
