Customer had an expensive bike carrier locked to their towbar. All keys lost and it was stuck on the back of the car. The only replacement keys that could be sourced online were in Australia. The customer needed the carrier removed that day before going on a long journey. Unusually this lock used a very thin laser key (cut with grooves down the flat face, as opposed to edge cut).
We soon unlocked the carrier without damage from the tow bar and customer went away happy.
