Why do people ask so much money for use oem bmw & mercedes key if there lock?

It is posible to unlock them So they can be used on another vehicle. A few kits out there for this. Also for spare pArts to repair broken keys

As a general rule, remote keys with separate Transponder chips can be RE used, those with built in Transponder and a coil on the pcb lock. There are exceptions, but I think this covers the majority

Doubtful as the USA uses a different frequency. Uk is usually 433mhz. USA uses 315mhz

Not all remotes in USA use 315mhz

this one in the link below is 433mhz

Anyway I read that they are reussable and I ordered 1 used from UK - They also could be replaced with KD remotes
