Unlocking the bicycle key

"I lost my bicycle key"

It seems that it is parked at a bicycle parking lot at a certain station on the Odakyu Line.There is a lot of traffic, so I'm worried about suspicious eyes.I asked the client not to leave.

It was a rare 5-pin tumbler cylinder.

I can't find the right tension.It took me a while to do this, but I unlocked it soon.

It was said that it was okay to unlock it, but since it was far from the work vehicle, I proceeded by picking.
