Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.
