Deadbolt door locks are the most secure type of key lock and are usually used on a home's exterior door. Available in single- and double-cylinder styles, deadbolts are rated according to their strength from Grade 1 to Grade 3. A Grade 1 is the highest grade and provides the most security.
Since they don't contain dials, keyed locks offer a superior level of security when compared to combination locks. Unless a thief has the key, he or she won't be able to open it. Furthermore, keyed locks are better protected against shimming than combination locks.

Smart locks often seem more secure than traditional deadbolts, but that isn't necessarily the case. Some electronic keyless systems have a chamber to store a backup key if there is a power outage, which someone unwelcome could potentially access.
So, yes it's true: combination locks are less secure than keyed locks. But if you get a decent one with 4 or 5 dials and features that resist the most basic decoding techniques, then in the street, in most instances they are going to offer the same levels of protection as a decent keyed lock.
Mortise locks are one of the most secure forms of residential hardware available today. What makes mortise locks so much more secure than their cylinder counterparts? A pocket cut into the short edge of the door, allows a longer and thicker mortise box to slide into the door itself, providing superior protection.
Deadbolts are the most secure because they need to be engaged when the door is shut. They have a unique locking device built into the bolt, that can't be forced back into the door, thus preventing unwanted entry.
Are electronic door locks safer than keyed door locks? Definitely not, but they are just as safe as keyed locks, and if a person is tech-savvy and wants ease of access instead of having to search around on their person for the keys to their home door, an electronic door lock is most definitely a good idea.
