Lost keys, ? New steering lock

Hello,
I have stupidly lost the keys for my series 3 petrol and I am wondering if there are any lock smiths out there who can make a new key from the old barrel. There are people on fb who claim this can be done but no one in the Dundee region will take the job on. Any suggestions would be greatly appreciated

I do not know if it is the same for the later model but I know for the earlier centre dash key locks the barrel is coded and you can just order a matching key for the barrel code. I did this for a series 2 dash panel I bought second hand to use bits for a series 1, it did not come with a key but matched the code, ordered a key, and had a fully working ignition switch again. Do not know if there is something similar for the later steering column lock barrels?
