Why Marcus Changed His Safe Combination After 15 Years in Sherman Oaks

May 16, 2026 · 4 min read

A Call From Ventura Boulevard

Marcus called us on a Tuesday morning in March. No emergency, no lockout, no drama. He just said, “I think it’s time I changed my safe combination. It’s been… a while.”

Turns out “a while” meant fifteen years. Marcus runs a small accounting firm near the intersection of Ventura Boulevard and Van Nuys, right in the heart of Sherman Oaks. He’d had the same Amsec floor safe since he opened the office in 2009, and the combination hadn’t changed once.

“Three employees have come and gone who knew that code,” he told our tech when he arrived. “My ex-wife knows it. I wrote it on a sticky note once that I lost in 2014. I just never thought about it until last week.”

What Made Him Finally Call

Marcus said he’d been at a networking lunch at Casa de Lago on Moorpark Street with a few other Sherman Oaks business owners. Someone mentioned they’d had a break-in — nothing was stolen from the safe, but the owner realized three former employees still had the combination. That story stuck with Marcus all week.

He looked up and found our number. Simple as that.

The Job Itself

Our technician Danny pulled up to Marcus’s office around 10:30 AM. The building sits in one of those two-story commercial strips between Kester Avenue and Noble Avenue — the kind of block where you’ve got a dental office, a yoga studio, and three different accountants all within shouting distance.

Marcus’s Amsec BF series safe was in solid shape. Good brand, well-maintained, no signs of wear on the dial. Danny verified Marcus’s identity and ownership, confirmed the current combination worked, and got to work.

A safe combination change on a mechanical dial lock like this one takes about 20 to 30 minutes when everything goes smoothly. Danny removed the back cover of the lock, reset the combination wheels, and programmed a new three-number sequence that Marcus chose. Then they tested it together — open, close, open, close — six times to make sure everything engaged properly.

“That’s it?” Marcus said.

That’s it.

Why This Matters More Than People Think

Here’s the thing about safe combination changes — almost nobody does them proactively. We get calls for lockouts, we get calls after break-ins, we get calls when someone inherits a safe they can’t open. But a routine safe combination change in Sherman Oaks? Maybe five percent of our safe-related calls.

And that’s a problem, because the whole point of a combination is that only authorized people know it. The moment that circle expands beyond who you intend — former employees, ex-partners, that one time you read it over the phone to your insurance agent — your safe is only as secure as the least trustworthy person in that group.

Marcus had at least six people who could have opened that safe. He trusted all of them, probably. But trust isn’t really the point. The point is control.

What We Recommend

After Danny finished up, Marcus asked how often he should be doing this. Here’s what we tell our clients:

A few more tips from the field:

Beyond the Safe

While Danny was packing up, Marcus mentioned he’d been meaning to upgrade the back door of his office too. The building’s rear exit had an old push bar that didn’t latch properly. We pointed him toward our panic bar installation in sherman oaks service and scheduled a follow-up visit for the next week.

That’s usually how it goes. One security upgrade leads to noticing the next thing that’s been neglected. It’s not about paranoia — it’s about catching up on maintenance you didn’t realize you were behind on.

A Quick, Affordable Fix

A safe combination change in Sherman Oaks is one of the least expensive security upgrades you can make. No new hardware, no construction, no disruption to your day. Danny was in and out of Marcus’s office in under 40 minutes, and Marcus went right back to his spreadsheets with one less thing nagging at the back of his mind.
