Rekeying Locks Cost in St Charles Typical price range $60 - $250 Fair Pricing ## Rekeying Locks Questions Here are the questions St Charles homeowners ask us most about rekeying. ## Frequently Asked Questions **Q:** How much does rekeying locks cost in St Charles? A: Most single-lock jobs run between $60 and $120, with whole-house jobs landing higher depending on door count. Historic hardware in Frenchtown costs more due to its age. We always quote the price before starting. **Q:** How long does rekeying take? A: A single lock usually takes 15 to 20 minutes. A full home with four or five exterior doors typically finishes in under an hour. We test every lock before we leave. **Q:** Can I rekey a lock myself? A: You can buy a rekeying kit, but it's easy to damage the pins or misalign the cylinder. We've seen DIY jobs that locked homeowners out entirely. A professional rekey takes less time and avoids that risk. **Q:** Is rekeying better than replacing the whole lock? A: Rekeying costs less and keeps your existing hardware, which matters for historic doors in the Main Street area. Replacement makes more sense if the lock itself is worn out or damaged. We'll tell you honestly which one your door needs. **Q:** How fast can you get someone out after a lost key? A: We treat lost keys as urgent and can usually get to you the same day. During ice storm season, calls spike and we prioritize lockout risks first. Call us and we'll give you a real time window. **Q:** What are signs my locks need rekeying? A: A sticky or hard-turning deadbolt, a recent move, or an ex-tenant with a key are all signs. Humidity near the river confluence also swells doors and misaligns locks, which can mimic a rekeying issue. We check both the lock and the frame when we visit. **Q:** Do you rekey smart locks too? A: Yes, we rekey and service smart locks common in New Town at St. Charles, including HOA-approved models. Smart locks still use a physical cylinder in most cases, so rekeying works the same way. We'll check your HOA's hardware rules if you're unsure.
