my engineer says the silver bleed keys, are slightly tighter than the brass gold ones. Dont know if hes chatting lies though

Your engineer is correct, they are a bit tighter,( at least, some are ), as are the ones on a thin bar. Just noticed: the thin bar type are the ones Gas man has pointed to- called rear bleed keys.

On certain clock types, it helps to grind down the face on a bench grinder.

For some reason the manufacturers splay the opening on each side. By grinding it down you are left with a simple square hole in the end. My younger brother taught me this, and I now do it to batches of keys as I lose them so often.

I keep my clock type rad key on my car key ring. That way I always have it to hand and if I lose it I know I'm stuffed for getting home.
