How our Change Locks works in Mill Valley

Discuss goals: We learn why you want the locks changed.
Choose the path: Rekey for speed or replace for new hardware.
Perform the change: We complete the work and hand over keys.
Test: Every door is checked before we finish.
Throughout the visit we keep you in the loop. Before we touch anything on your Mill Valley property, you will know what we found, what we recommend, and what it will cost — so there are never surprises when the work is done.
We come prepared. Our Mill Valley service vehicles carry the blanks, cylinders, programmers, and hardware for the vast majority of jobs, which is why we can usually finish in one trip instead of scheduling a return visit.

Change Locks: what to expect
For change locks specifically, change your locks for a fresh start. Before we open any home, unit, or vehicle, we confirm that you are authorized to enter. It is a simple step that protects you, your property, and your neighbors — and it is one of the ways a professional locksmith differs from a shortcut.
Common benefits customers in Mill Valley mention include new keys and, if you choose, new hardware, options to rekey or fully replace, consistent keying across the home, and a clean security reset.
So what actually happens when we arrive? First, we confirm the problem in person, because what sounds like one issue over the phone can turn out to be another. Then we lay out your options for Mill Valley, agree on a plan and price, and get to work.
We also try to leave you better informed. If a small habit or a minor upgrade would prevent this from happening again in Mill Valley, we will mention it — not to sell you something, but because an informed customer is a safer one.
