Non-Yale TARDIS Key? (Twice Upon a Time)

[LeoCor]

I was watching this clip from Twice Upon a Time, when I noticed something odd about the TARDIS key David Bradley was holding. Based on what I could see, it doesn't appear to be a standard Yale key, but rather a Kwikset house key. Judging from what I can see (which, granted, is not a lot), I can't seem to find the shoulders that are normally just above the teeth of the key, and the head of the key appears to have a hole that is off to the side, rather than in the center like on a normal Yale key. I could be wrong, but I'm not sure. Any thoughts?

It looks like the blade of the key is offset to the left of the head to me.

maybe it could look like this because of the cuts made to make  it work, the images of refrence as the blade not graved yet

Or it could just be held at an angle, I suppose.

I think the main trench down the middle... is pretty central, tbh.

But I do see what you mean, I think the "blade" does extend further to it's side than the other part does.

to clarify why it looks a bit diffrent (sorry i don't have hd caps)

This is my version if that's of any use -

That definitely looks to be the closest match to what appears on-screen.

Glad to be of help.
