Did you receive a sandwich bag of keys when you closed on your home? Lots of folks do.
One of the funnest parts of our job is what we've coined the "sanity rekey." A "sanity rekey" streamlines all your keys and synchronizes your locks to all open with the same key.
This takes the guesswork out what key goes where and gives you confident control of your new home right from the start. Why are folks always amazed that this can be done? Perhaps they've just learned to cope with the inconvenience of using numerous keys.
In addition to the "oil change" and deadbolt alignments, we always try to do a "sanity rekey" on every job if the hardware permits it.
