Electric commercial door locks use access codes to make it easier for you to gain access to your building – it also makes it easier for a thief with the right set of tools to do the same. Another thing to keep in mind is that a cheap lock, no matter how advanced the tech supposedly is, is a cheap lock. If you are using the services of a certified, professional locksmith, they will ensure a high-quality lock is installed that has the proper encryption and security protocols set up. When programmed correctly, both types of locks can provide a high level of security.
