My key stopped working well a while ago, took a good bit of fiddling to get the bike steering lock off and then some jiggling to start. I got some blank keys cut about 3 months ago and they worked perfectly but now I’m getting the same thing.

Is there anything I can do bar buying new lock barrels? It’s like the pins in the barrels have worn and that’s why it’s taking so much effort.

Hoping there is a cheaper option than new barrels
