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.

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.
