Slim Door Only Key

[Midwesterner]

New member and first time poster here, hoping for some help.

For the second time last night, the feature that prevents locking while key is in the ignition failed to work and I was distracted and didn't grab my key from the ignition. I used to have a hide-away key magnet with an un-programmed transponder so it only opened the door, but it fell off somewhere awhile back and I didn't replace it.

So now I'm wanting to get a non-transponder key that is slim enough to keep in my wallet. Does anyone know where I can get a blank? If I can get a blank, I'm sure I can find a locksmith to cut it for me. I would consider cutting the head off a key, but then how would I grip it to turn?

It is a 2009.
