Which Deadbolt Configuration Is Best? One Key Or Two

When it comes to home security, including a deadbolt as part of your door locking system is a must. However, more questions typically arise when it comes to deciding how to incorporate the deadbolt into your existing locks. More specifically, whether or not it's necessary to have one key for both locks or a separate key for the deadbolt. No configuration is universally better than the other, but there are certain scenarios when one setup is more beneficial.

Safety and Security

When it comes to any locking mechanism, the priority should be to improve the safety and security of your home. For this reason, you should analyze just how much you need to improve safety around your home. 

If you've experienced a break-in in the past or live in an area that has experienced burglaries in the past, a two-key configuration where you have a separate key for the deadbolt is best. In the event someone does gain access to one of your keys, they still won't be able to gain access to your home, which will ultimately help keep your home, and family, safer. 


It's a good idea to think about accessibility. For instance, who will need to use the keys to access your home? If it's just you or another adult, it might be okay to have a configuration where you have a separate key to unlock the deadbolt. 

On the other hand, if you have an older child or teenager that will need to use the keys to access the house by themselves, such as after school, it might be more of a challenge for them to keep track of two separate keys. In this instance, a single key to unlock both locks might be the better option. 

Lifestyle Needs

Take your lifestyle into consideration, as well, when you make your decision. For example, do you have a long commute to work that involves riding several buses or trains? If so, you have to think especially hard about convenience. 

With improved convenience in mind, the fewer keys you have to carry with you along your commute, the better. As a result, to make things easier for yourself, it might be a better idea to go with a single-key configuration. However, even if you prefer convenience, if two keys will make your home more secure, it's the better option. 

If you need more help deciding which option will work best for you, don't hesitate to ask a locksmith for assistance.
