It should be a straightforward procedure, but rarely goes to plan. [French electrics...]

Acquire all the keys and the security pass which has a four-letter [scratch and sniff] code on it.

Access the BSI with your £6000 high-end scan tool and enter the security pass letters. Enter them again.... and again...

Erase all the existing keys and re-programme the new keys in following the prompts on the screen.

Complete the procedure; check that all the keys start the car and their remotes all function.

Pack away the scan-tool and lock it in your vehicle.

Retry the keys to find that it's forgotten them all.......

Unlock vehicle; re-assemble scan-tool, re-enter BSI.....

[Repeat last four steps until darkness has fallen.....]
