i think you should buy a small pick set and try to rake it (or just buy a rake and tension wrench). I have had my picks for 2 days now, i managed to rake a small abus padlock very easily, it look less than 10 seconds.
this is the site i got my picks from (UK):
http://www.locksmith-tools.co.uk
they processed my order fast and postage was reasonably priced and fast. If you do decide to buy some picks, be SURE to get the UK/euro slim line style as the standard picks will probably be too big for most UK locks.
other than that i would consider the other guys idea of make a BIG deal about losing the keys im almost certain that he will either believe that he has lost the keys or, he wont want to upset you anymore so he will not argue, as far as he is concerned he will just let you think that he has lost them, even if he believes that it was you that lost the keys.
other than that....there are many ways a girl can get something from a guy (or in this case get the guy to forgive the girl) just use your imagination
