Moving Into a New Home in San Jose? Your Rekey & Security Checklist

Why rekey before you unpack a single box

Closing on a house or signing a lease in San Jose is a great feeling, but here's an uncomfortable truth: you have no idea how many keys to your new home are floating around the South Bay. The previous owners almost certainly kept a spare. So might the listing agent, the cleaning crew, a contractor who did work before the sale, a dog walker, a neighbor who watered the plants, or the last few tenants if it's a rental. None of those people are necessarily a threat, but every one of them is a key you don't control.

Rekeying solves this cleanly. A locksmith resets the internal mechanism of your existing locks so every old key stops working and a fresh set takes over, without replacing the hardware you already have. It is usually the fastest and most affordable way to make a home truly yours on day one. That's why we suggest treating it as a moving-in task, right alongside switching utilities into your name, not something to get around to 'eventually.'

Walk the property: what to actually check

Before you call anyone, do a quick walk-around with a notepad. New San Jose homeowners are often surprised by how many separate entry points a single-family house has once you start counting. Renters in apartments and townhomes around the South Bay have fewer, but the same logic applies. Make a list of every lock and entry point so you can get an accurate picture and an accurate estimate.

• Front, back, and side entry doors — note the deadbolt and the handle/knob lock on each, and whether they currently share one key
• The garage-to-house door — the interior door from an attached garage is a real exterior door and is often the weakest and most overlooked lock in the house
• Sliding glass and patio doors — common in Eichlers and many Santa Clara County homes; check that the latch is solid and ask about an auxiliary lock or a security bar
• The garage itself — if there's a keypad or remote, plan to change the code and clear out old remotes you didn't get
• Mailbox locks — especially for cluster/community boxes in San Jose neighborhoods and apartment complexes, where a previous key could still open yours
• Side gates and backyard access — a locked gate is your first layer; note any padlocks or gate locks you can't open or don't have keys for
• Any safe, shed, or storage room left behind with the property

A sensible priority order for your first week

You don't have to handle everything on day one, and you don't have to do it all at once. Spreading it over your first week keeps it manageable. Here's the order we'd suggest, working from the points that matter most for keeping people out to the ones that are more about peace of mind.

• 1. Rekey or change the exterior door locks — front, back, side, and the garage-to-house door. This is the single highest-impact step.
• 2. Reset the garage keypad code and remove unknown remotes, so an old opener can't raise the door.
• 3. Secure sliding doors and ground-floor windows — a simple auxiliary lock or bar goes a long way.
• 4. Lock down the perimeter — gates, sheds, and the mailbox.
• 5. Consider 'keyed-alike' service so one key opens all your exterior doors, which is a nice convenience to set up while a locksmith is already on site.

Typical cost ranges in the South Bay (and how pricing works)

Everyone wants a number, so here's an honest one with a caveat: the figures below are typical industry ranges for the kind of standard residential work new homeowners ask about, not a quote for your specific home. Actual pricing depends on how many locks you have, the type and condition of the hardware, and whether you're rekeying versus replacing. The fair way to handle it is simple — we confirm the price with you before any work begins, so there are no surprises.

As a rough guide for planning purposes only: rekeying an existing lock commonly falls in the ballpark of $20–$50 per lock cylinder, plus a service-call or trip fee for a mobile visit; replacing a deadbolt with new hardware typically costs more, since you're paying for the lock itself plus installation, and it varies a lot by the grade of hardware you choose; keying multiple locks alike is usually priced per cylinder, similar to a rekey, and is most efficient done all in one visit; and mailbox, gate, and auxiliary sliding-door locks are generally modest add-ons depending on the hardware.

A practical money-saving tip: batch the work. Because a mobile locksmith comes to you, getting everything rekeyed and secured in a single appointment is almost always cheaper and less hassle than spreading visits out over weeks.
