This Replacement Keychain Accessory has been a game changer for me. They were so easy to install and they gave my old worn OUT keychains a fresh new look .After i put it to the test on my car keys, they provided an extra layer of protection for my car key fob. The only downside was that they were a bit difficult to remove once I had them on. Overall, I would highly recommend this product to anyone looking to spruce up their automotive keychains!
