We had to get another key for our GS 300. we went to Lexus Woodford in Essex and the cost of the key and remote locking was £60 and £30 or thereabouts + VAT and a half hour to reprogramme the key or something. It took about a week, and if you look a bit untrustworthy, like I did, they do ask for proof of ownership. <_< :arrrggg-matey:
