Need A New Key

Hi all - my new-to-me Thruxton R only came with one key. I'm shortly going to book it in for a service over at North London Triumph - anyone know if it's straightforward to order a copy key and/or how much it's likely to cost?

TIA

 

Thanks Ade - that's certainly an option.

 

Well, just for info I just booked the bike in for a service and - at the same time - ordered a user manual and a spare key (fully programmed and paired to the bike). Those two together came to £99 so all in all I'll look at it as a result (and the seller of my bike just gave me £50 towards it).
