Also, SL320, I looks back and forth four times, all I could find was the blade. I found the blade before I left the gate and onto the the main street.

Never even saw a single trace of the rest of it. I learned my lesson the hardest way, in the end, all the key needed was a tiny little screw that sits at the bottom of the key blade.

Totally my fault. Also I think the fat chipped key you mentioned is long gone from production.

Don't forget to grease the screw and threads on the spring compressor.
