Hello, do you have a spare key you could try?
It may have a stuck tumbler in the switch. IF you have some WD-40, lithium grease or even machine oil, put some down the hole where the key goes and move the key up and down rapidly in a sawing motion. Let me know how things go.
Glad to hear it, they tend to gunk up over time and do that.
