WD-40 comes to the rescue.....scary thought.

So my Mercedes is in the shop being held hostage to back ordered parts.....Freaking emission control parts for the DEF diesel schizzle. Been there a month. Another frustrating story.

My 911 is my daily driver as a default. The Optima battery was recently resurrected from the dead, so I check it every day for current charge (no, I'm not anal just cautious). As a habit I put the key in the ignition.

Damn thing wouldn't turn....no problem, wiggle the steering wheel. Nope....no problem, turn the key over....nope. No problem use the spare key.....nope.....SHIZZLE!!!!!!

Tool kit, graphite.....schizzle! Lost in the ether......wait, a sample sized can of WD-40, the red nozzle still attached by tape. Virgin can.

Spritz....key turns like butter.

Now I always thought of WD-40 as snake oil. B U T this time it bailed me out.

Not the best lube for a key way.....but time will tell.
