Help

Hi there, I am in serious need of your help. I have lost my keys I think I left my keys in a taxi in Dublin yesterday either going from ranelagh to town or vice versa. Or either captain americas or the hairy lemon pub. these were the only place I was. They are a bunch of keys containing a VW black rectangular key, with a button that flips the key out, also have roughly 4 other keys and 2 keyrings one blue and one yellow and also a small fob for the corrib oil petrol stations and also a padlock locked on to it. Im so distraught without them. please help if you can. Thank you. Kind regards
