About the service
Professional Lock Change in South Pasadena
Most lock-change calls we get in South Pasadena are for older houses — the Craftsman bungalows and 1920s homes on the streets off Mission. The original hardware is often a mortise set or a builder-grade knob well past its prime: the bolt drags, the key wiggles, the finish worn to bare brass. If you just closed on a place, swapping the lock outright usually beats rekeying it.
Rekeying fits when the lock is still solid and you only need the old keys to stop working — a rental turnover, say. A full change wins when the mechanism is tired, when you want to step up from a flimsy grade to something bump- and pick-resistant, or when the hardware doesn't suit a restored door. We'll tell you straight which one your door needs.

What to expect
What Happens When You Call Us in South Pasadena
When we reach the door, we check what it's drilled for — the backset, the bore, and whether it's a standard bore or a mortise pocket, since a lot of older South Pas doors take mortise hardware you won't find at a big-box store. We measure before pulling anything and talk through grade: a Grade 2 deadbolt covers most homes, Grade 1 for the strongest bolt on an exterior door.
South Pasadena is compact and quick to reach from our San Gabriel Valley routes, so same-day is normal, and we run 24/7 for lockouts and break-in repairs. A single deadbolt swap takes fifteen or twenty minutes; a whole house keyed alike, so one key runs every door, is closer to an hour. If your door needs a mortise part ordered, we'll say so on the spot instead of forcing a wrong fit.

Common questions
FAQ
Should I change the lock or just rekey it?
Rekey if the lock still works smoothly and you only need the old keys to stop opening it — common after a rental turnover. Change it if the bolt drags, the key sticks, or you want a stronger grade than the builder-grade set that came with the house. On a lot of older South Pasadena doors the original hardware is worn enough that a change is the better spend.
What lock grade should I get?
Grade is an ANSI rating for how much a lock can take. Grade 3 is basic builder hardware, Grade 2 is the sweet spot for a home, and Grade 1 is the toughest — good for the front or any door facing the street. For most South Pas houses we put a Grade 2 deadbolt on interior-access doors and a Grade 1 on the main entry.
How long does a lock change take?
A single deadbolt is about fifteen to twenty minutes. A typical house — front, back, and a garage or side door, all keyed alike — runs close to an hour. If your door takes a mortise lock we don't stock on the truck, we'll order the exact part rather than force a modern bore into an old pocket.
Can all my locks open with one key?
Yes — we key the new locks alike so one key runs the front, back, and any other door we change that day. If you'd rather keep a separate key for a guest unit or the garage, we can do that too. Just tell us how you want it split before we cut the keys.
