All sorted, in case it helps anyone else finding this through Google I got mine from this company based in Sheffield, cheapest I could find at £4.99 with lots of good TrustPilot reviews so took the plunge and got my code straight away https://www.rapidradiocodes.co.uk/manufacturers/land-rover

Hi did anyone here manage to actually get their code? Last numbers trick definitely doesn't work for me and dealership have quoted £20 like alison says above. Is there a cheaper solution that anyone can vouch for?
