Setting this synchronization involves specialized software application and hardware that requires considerable investment from the company. Moreover, for the latest designs, the security data is kept on a secure server in Germany, and the "handshake" in between the car and the server need to be authenticated through the dealer.

4. How long does the replacement process take?
At a car dealership, it can take 2 to 5 company days due to the fact that the key is often bought from a central distribution center and delivered to the dealership. A specific mobile automobile locksmith can often complete the job in 1 to 3 hours, provided they have the right key blank in stock.
