Ignition key and lock tumbler replacement instructions - key is stuck

It was the ignition key switch that was sticky.

I sprayed some WD-40 into the ignition key hole at some point, and that appeared to have caused the problem, for this also makes dirt get accumulated/stuck in the switch.

So I rinsed it out with alcohol, and then let it dry, then got some key lubricant(graphite from Lowe's), and that solved the stickiness. Still going strong
