FREE: Transformers Cyber Keys (Winner chooses 1)

Yes.

I'd rather take my chances--there are three other watchers. I would, however, reduce the number of days a bit.

I get it, no problem.

I'll still take my chances--if there's one key in that bunch I can use, it's definitely Excellion's, since I found the Excellion figure at a thrift shop a year ago.

I may have solved the mystery of your unmarked keys.

Before I get into that, I should note that of the ones you marked, Override came with a gold and red key, not the silver and red ones you have here. Check TFU.info for more on that.

Anyway, the other keys go to the following:

The red key with the silver Autobot symbol goes to either
-The Sam's Club-exclusive Optimus Prime

-Or the Target-exclusive Universe Springer or Roadbuster

The purple-ish key with the silver Decepticon logo goes to either the Target-exclusive Universe Ratbat or Dirge

http://tfu.info/2008/Decepticon/TFUDirge/dirge.htm

The gold and blue sun key goes to either the Cybertron Starscream or Cybertron Evac

Er, check that, throw the Sam's Club Prime out.

Also, the red key/silver Autobot logo could also go to the 2007 Movie line's Wingblade or Breakaway:

The black and silver key with the red Autobot logo is a real stumper to me.

All right, last one, I swear--the black and silver key is for the 2008 Universe Blaster.
