I know that's a resistor in there, but can anyone id that chip and the gold part behind the wires, is that flux or something? Sorry for be so thick :confused
The IC may be a 555 timer chip

I was thinking the same thing.
It may just be colored glue, to make it look a little 'electronic-y'

555 timer was exactly my first gut reaction as well.
Of course if you want to be completely authentic, you have to get the correct resistor...

the gold part looks to me like it could be a piece of a cell phone sim card

What you need there is a 10k resistor: DigiKey Part
and the 555 certainly would work
The gold thing, It almost kinda looks like one of those chips on credit cards now a days. Tough it looks like it could be (or was) made by cutting a piece of thin sheet brass and acid etching it so it has that multiple-level appearance as it does in those photos. That and if you used brass you could get the solder on the red wire to actually stick to it with a bit of flux.

Where did you get that pic, did the key always have electronics on it? It kinda looks to me like the chip was cut, the edge doesent seem flush, and yes, the gold part looks like its from a sim or credit card

the key is from the episode sound of the drums the doctor makes them so that they can hide slightly

Sorry for bumping an older thread, but I've been lurking for a while and I've chosen this key as a first build and just thought you guys might be able to provide some clarification. I've viewed the scene of "sound of the drums" where the Doctor builds the three keys, and...
a) I don't see the shot where the OP's screenshot is from. Is it from the episode?
b) Is the OPs pic from an episode or another canon reference or is it itself a replica? The resistor placement and black wire placement don't seem to match what is shown in the build sequence (about 28:20 into the episode)
Thanks in advance.

Excellent! Thank you so much for replying. I already have a fried 555, a correct value resistor and a sim card I can butcher, so a trip tomorrow to the locksmith should get me all set.
I also have a couple more questions if you don't mind.
a) It looks as if the components are attached to the key with a clear epoxy, as opposed to solder. Is this correct?
b) Do you know anything more detail-wise about the twine cord? It looks to be twine at least. Do you know how thick is was? How long the loop was? Although I could find out how tall Tennant is and extrapolate the length from that with a decent margin of error, I'd rather not have to...
Thanks again!

You don't happen to have a larger version of this pic do you?
I can almost read the writing on one of the chips. If you have one, you can email it to Wookieegunner@highlandcitadel.com if you want.
