There are pros and cons to each lock type. It usually depends on your needs and whether you prefer the convenience of a smart home. For instance, a keypad lock means that you don’t have to have your key on you. But it also allows anyone who has the code to gain entry to your home. A Wi-Fi smart lock lets you open your door remotely for visitors and repairmen. However, it can also be hacked. Finally, a mechanical lock requires you to have a key, which can be inconvenient. But potential thieves may have a hard time finding a way around that requirement. Always keep the pluses and minuses of each lock type in mind when making a decision.
