Locksmiths questions, answered by experts

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.

In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk. 

When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.

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.
