There are a few types of keys available when it’s time to replace lost, broken, or damaged car keys. Aftermarket replacement car keys are keys that are blank and have not been programmed to work on any model or make of vehicle. These keys are not made by the original vehicle manufacturer like traditional car keys and usually are a lower quality. However, this is not always true and choosing a quality provider to make the key, if you opt to use an aftermarket, will reduce the risks of getting a poor key.
