Key broke while inserted in the gas lid

[ST Gui]

I managed to remove the broken key using a tweezer.

That's a nice find. I have a pair of fine pointy tweezers I got in a small repair kit from iFixIt. But I didn't have them on me when I broke my key that was already stuck in the cap. A friend showed up with a spare key and a dental-type pick and dug it out.

Then I got some ILCO X265 blanks which are steel and much stronger and had keys made. I believe another compatible blank is HD109.
