These work great! I now have one on my backpack zipper for when I forget my access badge at home. ### ⭐⭐⭐⭐⭐ Quick delivery, good quality. *by on Reviewed in Australia 13 November 2024* Quick delivery, good quality. All work. ### ⭐⭐⭐⭐⭐ Almost perfect in every way *by on Reviewed in Canada 21 October 2023* These little key fobs are great. They program with ease and keep on working. A better ring to attach to a key ring would be my only change.
