Key wouldn't turn in ignition - used WD-40 - next steps?

[saferider1]

I have a 2012 Taotao ATM150-A Evo 150cc bike. Brand new, first test ride was 2 days ago.

Still working out the bugs. Today after fueling up, the key would insert but wouldn't turn in the ignition. Couldn't turn to the start position or to lock the handle bars.

Played with the key for a few minutes then got on scootdawg via a google search on my phone. Lube was recommended. Fortunately, Lowes does that trinket marketing by placing stuff they think you need along the aisles. The other day, I saw a 3 oz can of WD-40 and thought, hey, that should be in my toolkit on my bike. So I had some WD-40 with me!

So with a squirt of WD-40 in the lock, something freed up, and I was able to start and roll.

Here's my question. Did I screw things up by using WD-40 instead of graphite? Can I still squirt some graphite in there? What do you guys recommend as the next steps in preventative care?
