Door hardware is one of the most frequently cited ADA and fire code violations in California. We assess your doors, handle remediation, and document everything — so when an inspector shows up, you're covered.
A door that won't latch, an exit device that sticks, a lock that fails — these aren't just nuisances. They're liability. We respond quickly, fix things correctly, and document our work so you have a paper trail.
With A & J, you get Nir — the owner, 25 years of commercial experience — every time. No surprises.
Based in Woodland Hills. If it's in the Valley, we likely cover it.
My name is Nir Zvingler. I started A & J Lock and Key 25 years ago, and I still show up to every job myself.
When you call A & J, you get me. Not a dispatcher. Not a technician you've never met. You get the person who's been doing this for 25 years and still takes pride in getting it right.
I'd rather have 30 clients who trust me completely than 300 who barely remember my name. That's the business I've built.
I built this business on commercial properties — apartment complexes, office buildings, industrial parks, retail centers. I know what property managers deal with: tenants who need things fixed yesterday, inspectors who don't give second chances, and budgets that don't have room for someone to come back and do the job twice. That's exactly why my clients keep calling me back.
If you manage commercial property in the San Fernando Valley and you're tired of dealing with companies that treat your building like a number — give me a call. I'll give you a straight answer and show up when I say I will. That's the whole pitch.
Real jobs. Real properties. Across the San Fernando Valley.
