"When I was locked out of my home I search on google for a local locksmith. Contacted Mr. Dominick from Safeguard locks, he is a very professional locksmith, punctual and charged me fairly. Before I decided to hire him I also contacted two other locksmith companies in Norwalk Ct but I decided to hire Mr. Dominick because his knowledge gave me confidence that he could do the job right. I was right, he was very respectful of my home, explain in details the job and the cost.. no surprises. If you live in Norwalk Connecticut or Fairfield County and you need a licensed locksmith for your home, car or truck look no further than Safeguard locks and ask for Mr. Dominick, he is truly the best locksmith I have ever worked with."

"ADT is the best company to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths questions, answered by experts

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

The cost to hire a locksmith varies depending on the service you need. Consult your locksmith about the price of your requested services before hiring for your repair or installation. Some of the most common types of locksmith services include:

  • Installing deadbolts: $40–$75

  • Rekeying: $80–$160

  • Unlocking your house: $65–$180

  • Changing locks: $50–$200

  • Installing electronic locks: $50–$500

  • Installing smart locks: $200–$800

  • Keyless locks: $50–$300

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.

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.

It depends on the quality of the keyless lock and usage, but in general, you can expect a keyless lock to last around three to five years. The batteries typically last around six to 12 months. The good news is most keyless locks include a low battery indicator so you can receive ample warning if your battery is about to die.
