Key programming...

Missus has at some point lost the spare to her Tiguan. Panic as she thought she'd lost the remaining key tonight. Stealers wanting extortionate amount for replacement so decided to hunt down a blank on interweb.

I've bought a replacement key off Aliexpress with same part number for the measly sum of £8 but need to find somebody local who can code it without breaking the bank.
