We get calls like this almost every week: a homeowner in Sherman Oaks realizes their front door has nothing but a basic knob lock. No deadbolt. Sometimes they’ve lived there for years without thinking about it. Sometimes a neighbor’s break-in is the wake-up call. Either way, the fix is straightforward — but there are a few things worth getting right.
Our crew handles deadbolt installation in Sherman Oaks on a regular basis, and we’ve picked up a lot of local knowledge along the way. Here are six tips specifically for Sherman Oaks residents who need to upgrade that front door.
1. Understand Why a Knob Lock Alone Isn’t Enough
A doorknob lock can be defeated with a pair of pliers and about ten seconds. That’s not an exaggeration. The latch on a standard knob lock is spring-loaded and beveled — it’s designed for convenience, not security. A deadbolt throws a solid steel bolt into the door frame, and it can only be moved by turning the key or the thumb turn. That’s the difference between a suggestion and an actual barrier.
We see this a lot in older Sherman Oaks homes near Moorpark Street and Dickens Street — many of those 1950s and 60s builds came with just a knob lock on the front entry. The original hardware was fine for a different era, but the neighborhood has changed.
2. Check Your Door and Frame Before You Buy Anything
Not every door is ready for a deadbolt out of the box. You need at least 1-3/8″ of door thickness (most standard doors are 1-3/4″, so you’re usually fine). The bigger issue is the frame. Hollow or rotted door frames — common in some of the older apartments along Van Nuys Boulevard — won’t hold a deadbolt strike plate securely. If the wood crumbles when you push a screwdriver into it, the frame needs reinforcement or replacement first.
If you’re dealing with a metal security door or a door with decorative glass panels, the installation gets more specific. That’s where calling a pro for deadbolt installation in Sherman Oaks saves you from a costly mistake.
3. Pick the Right Deadbolt Grade
Deadbolts are rated by ANSI/BHMA grades. Here’s the quick version:
- Grade 3 — residential basic. Better than nothing, but just barely.
- Grade 2 — solid residential pick. This is what we recommend for most Sherman Oaks homes.
- Grade 1 — commercial-grade. Overkill for most houses, but great if you want maximum durability.
Brands like Schlage and Kwikset both make reliable Grade 2 deadbolts in the $40–$80 range. We carry several options on our trucks so homeowners can see them in person before deciding.
4. Don’t Skip the Strike Plate Upgrade
This is the single most overlooked part of any deadbolt installation. The strike plate is the metal piece on the door frame that the bolt slides into. Most deadbolts come with a flimsy strike plate and short 1/2″ screws. A solid kick will rip it right out.
We always install heavy-duty strike plates with 3″ screws that reach into the structural framing behind the door jamb. It takes an extra five minutes and costs almost nothing, but it makes the door dramatically harder to force open. If you’re near the Sherman Oaks Galleria or the homes off Hazeltine Avenue — areas where package theft and doorstep crime have ticked up — this detail matters.
5. Think About Keyway Compatibility
If you already have a Schlage knob lock, get a Schlage deadbolt. Same goes for Kwikset. Matching the brand means your locksmith can key the deadbolt to match your existing knob lock so you carry one key instead of two. We do this on-site during every installation — it only adds a couple of minutes.
For homeowners who want to go keyless, smart deadbolts with keypads or Bluetooth are a solid option. We install those too. Just know that a smart lock still needs a quality strike plate and proper alignment to actually be secure.
6. Get It Installed Right the First Time
YouTube makes deadbolt installation look like a 20-minute project. And sometimes it is — on a brand-new door with a perfect frame. But in Sherman Oaks, we deal with a lot of real-world conditions: slightly warped doors from summer heat, misaligned frames from foundation settling (especially in the hillside homes above Ventura Boulevard near Coldwater Canyon), and old hardware that doesn’t come out cleanly.
A bad installation means a bolt that doesn’t fully extend, a door that sticks, or a strike plate that’s already loose on day one. Our team does this work every day across Sherman Oaks, from the condos on Riverside Drive to the single-family homes south of Magnolia. We know what to expect and we bring the right tools.
