Horrible experience with Kryptonite locks!
I've had my new $133 Kryptonite 999492 14mm x 60" (1415) New York Fahgettaboudit Chain and New York Disc Lock for two weeks and used it a few times with success.
Last weekend I had great trouble getting the lock locking hasp to open fully in order to insert the u-shaped shackle. It took about 20 minutes of carefully and repeatedly inserting the keys, poking my pinky finger into the lock holes to press on the partially stuck mechanism, and sending atheist prayers to the bike gods that don't exist.
I finally got the damn thing to open.
Today I the keys won't open the lock at all and my $2,000 ebike is stuck.
I've tried all three keys to no avail. I called today (Saturday) and of course there's no one there to help me out of this desperate situation.
I'll continue my attempts this weekend while I wait for Kryptonite representatives to respond.
