Things that have not worked (so far):
Youtube video recommended a specific bike lubricant but that didn’t work.
I read hitting it with a hammer could help knock some of the rust loose but so far nada.
How it got stuck: I got doored pretty bad a few months before getting pregnant several years ago and basically stopped riding completely afterwards bc drivers are such assholes in the city where I live.
My stbx always chastised me for storing it in the house, and after we moved together the last time in 2021, he started making me keep it outside under a tarp.
Now he’s gone and it’s my only means of transportation, but the lock is stuck like a yoke around the neck.
I can feel something turning inside after a half revolution when I try to unlock it with a key, but I can’t even remember if it’s supposed to make a full revolution and is getting stuck halfway or if that’s as far as it’s supposed to turn (as in, is the rust is inside the barrel or the keyhole?).
Any other tips or ideas to get it open?
My dad said he thinks worst case scenario we can just cut it off, but it’s a kryptonite lock and I thought they were supposed to be impossible to cut?
Penetrating oil, let it sit, smack it a bit, repeat until open.
Getting some stuff so you can grip it and wiggle helps.
Are you trying to save the lock? Fastest way is just to cut it with an angle grinder. Harbor freight will get you a cheapo that will work fine. Cheaper and more difficult to use the lube+smack method.
If you use the grinder make sure to get some eye protection as well, and earplugs.
PB blaster is my penetrating oil of choice.
As others said, you can take the handlebars off, then deal with opening the lock it you still want to use it.
Me personally, I’d get a new lock just to be sure it doesn’t act up again and leave me stranded with my bike locked up.
