Locksmiths questions, answered by experts

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Always consider security a top priority in your home. Perform a safety inspection of your home. Look for broken locks and rusty deadbolts, and take an inventory of who has access to your keys.

Consider the locks on your shed, safe, and other household items. Professional locksmiths can help you determine the best safety and security options for your home and feel at ease.

When a locksmith comes to your home, ensure your safety by having the locksmith show identification and provide an itemized invoice that you can reference later.

Deadbolts are solid and durable as can be, but the pin and tumbler can still be forced open, thus making this type of lock susceptible to picking. Most types of deadbolts are harder to pick than a traditional spring-based lock, though. It requires a specialized lock pick and a tension wrench to align all of the pins, thus unlocking the door. 

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.
