When it comes to home security, Metro Locksmith recommends rekeying existing locks instead of replacing them with lower quality locks available at big box stores. In most cases, homes are already equipped with high-quality locks that can be rekeyed to work with a new key. This is a cost-effective solution that can save homeowners money in the long run, as rekeying maintains the integrity of the original lock while updating the key. Overall, rekeying is a smarter and more secure way to invest in home security.
