Take care of your car keys to prevent the need to replace them as often. Keys are constructed of quality metal materials designed to last for many years, but if the keys aren’t taken care of, this amount of time diminishes significantly. Keep your key out of water, make sure that they’re kept on a keychain, and do not force a key into a lock. Proper key care reduces the risk of breaking or chipping the key, which causes the need for replacement car keys much sooner.
