The biggest advantage for me is the ability to change keys at any time. My family tends to lose keys and this used to be a problem due to the cost of a locksmith. Now when it is necessary to replace our locks with a new key, I just follow a few simple steps for each lock and the job is done. Be sure to follow the instructions carefully. I once pulled the key too soon while installing a new lock and had to spend thirty minutes repeating the process to find the exact spot where I originally went wrong. Aside from that one occasion, these locks are absolutely worth their price. It's also worth noting that every set of locks you buy comes with a smart key, so let's say if you buy 4 sets. Now you have 3 replacement sets where you can change the locks at any time.
