Locksmith Tips & Security Advice from Locks R Us Locksmith
Our locksmith tips help you compare lock repairs, rekeying and replacement, prepare for a service visit and manage everyday access safely. Start with rekeying versus replacement, a sticking lock, or car lockout advice.
Most people only think about locks the day something goes wrong a key snaps off in the deadbolt, a car fob dies in a parking lot, or a tenant moves out with a key nobody accounted for. This blog exists to move those moments earlier, while they’re still cheap and easy to fix. Our technicians work on doors across Ballwin, Manchester, Ellisville, Chesterfield, and the rest of St. Louis County every day, and the same handful of problems come up again and again. Below we share what we see in the field: how to tell a good lock from a cheap one, when rekeying beats replacement, what to do before you call anyone, and how to avoid the scams that give locksmithing a bad name.
