One Key
Do you fumble in the dark with your keys, getting frustrated somehow managing to always try the wrong one first?
Do you sometimes leave the back door unlocked because you need to let someone have access to your home, but your not sure which key they have?
Or are you just not quite sure who does have that spare key?
These are all valid reasons to let the LOK DOC re-key your existing locks to the same key to give you back that feeling of security that every home owner deserves.
