Wellll, after going to Ace on three different occasions, in two different towns, I was still unable to get my key duplicated correctly. Alas, Hampel saved the day and now I am able to distribute as many keys as I wish! Kidding, kidding. But they work, and I’m happy. They also stamp their name and number into the keys which I find to be great advertising. Sidenote: I in fact, was not the one who physically went to Hampel’s, so I cannot comment on their face-to-face customer service, or location. But their product is legit, so that is worth a review in my book.
