Locksmiths FAQs, answered by experts

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

Smart locks offer a similar level of safety to traditional or conventional locks because they often use comparable locking mechanisms, such as deadbolts. The primary difference is the access method: smart locks use a login or code instead of a physical key, which adds convenience. While not inherently safer, some smart locks have added security features that can deter intruders, like shutting down after too many incorrect code attempts or being harder to pick. For the best security, it's recommended to combine any lock with other home safety features like motion-activated lighting, security cameras, and window and door sensors.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.
