Why someone hasn’t thought of this idea before, I don’t know, the simplest ideas are always the best, the Split Ring Key.
The Split Ring Key is basically a key, with a key ring built in, and it is being sold as a blank key so you can take it to your locksmith and get it cut.
This is a brilliant idea, if you want one they are available for $7.00 each from Amron Experimental, and the company is also selling a 30% stake in the patent design, I can see some big key manufacturer or locksmiths buying into this as it is a great idea.
