That Knob Lock on Your Front Door Isn’t Enough
We get this call almost every day at Locksmith HQ. A homeowner in Silver Lake or Palms finally takes a close look at their front door and realizes the only thing standing between their family and the street is a hollow brass knob from the 1970s. No deadbolt. No secondary lock. Just a spring latch that a determined teenager could pop with a credit card.
If that sounds like your door, you’re not alone. A huge chunk of older bungalows, Spanish-style homes, and duplexes across LA were built with single knob locks and never upgraded. We’ve walked into houses near York Boulevard in Highland Park, off Venice Boulevard in Mar Vista, and up in the hills above Los Feliz with the same setup. The good news: a proper deadbolt installation in Los Angeles is one of the cheapest, fastest security upgrades you can make.
Why a Knob Lock Fails Where a Deadbolt Holds
A knob lock uses a spring-loaded latch, usually with a throw of about half an inch. That latch retracts under pressure. A deadbolt, by contrast, is a solid metal bar that slides into a reinforced strike plate in the door jamb. It doesn’t retract unless you turn the key or thumbturn. Big difference when someone’s shoulder is against your door at 2 a.m.
LAPD’s Rampart and Hollywood divisions both publish burglary reports regularly, and forced entry through weak front doors remains one of the top methods. A deadbolt doesn’t make your home bulletproof, but it removes the easiest path in.
7 Tips from Our Team Before You Install a Deadbolt
1. Check Your Door Material First
Solid wood, solid core, and metal doors handle deadbolts well. Hollow-core interior-style doors (we see these on a lot of older rental duplexes in Koreatown and East Hollywood) really shouldn’t be your front door at all. If yours is hollow, replace the door before adding hardware. A deadbolt in a hollow door is security theater.
2. Measure the Backset
Most LA homes use either a 2-3/8″ or 2-3/4″ backset. Pop your knob off and measure from the door edge to the center of the hole. Getting this wrong means a deadbolt that won’t line up and a hole saw mess you’ll regret.
3. Pick a Grade 1 or Grade 2 Deadbolt
ANSI/BHMA rates locks Grade 1 (commercial), Grade 2 (heavy residential), and Grade 3 (basic residential). For a front door in LA, go Grade 2 minimum. Schlage B60N and Kwikset 980 series are solid picks we install constantly. Skip the bargain-bin builder-grade stuff from big box stores.
4. Upgrade the Strike Plate and Use 3-Inch Screws
This is the step 90% of DIYers skip. The little screws that come in the box go maybe 3/4 of an inch into the jamb. Swap them for 3-inch screws that bite into the wall stud behind the jamb. It’s free and it roughly doubles your kick resistance.
5. Match It to Your Knob (or Rekey Both)
If you want one key for the knob and the deadbolt, have a locksmith key them alike. We do this on the spot. Saves you fumbling on the porch with a bag of groceries.
6. Don’t Forget the Side Door and Garage Entry
On a lot of LA homes — especially the Craftsman and Spanish houses in Eagle Rock, Atwater Village, and Leimert Park — the side door or kitchen-to-garage door is the weak link. A front deadbolt doesn’t help if the side door still has a 40-year-old knob.
7. Think About Your Gate and Perimeter Too
Many neighborhoods from Hancock Park to Sherman Oaks have courtyard or driveway gates. A deadbolt on the front door is step one, but if you have an exterior gate, that’s your real first line. We handle gate lock service in los angeles regularly and it pairs naturally with a front-door upgrade.
Smart Deadbolt or Standard? The LA Angle
Smart deadbolts (August, Schlage Encode, Yale Assure) have taken off in LA because so many of us have short-term guests, cleaners, dog walkers, and food deliveries. If you’re near USC or in a walkable pocket like Virgil Village, a smart deadbolt with auto-lock is worth the extra cost. For single-family homeowners in the Valley who just want something bulletproof and boring, a keyed mechanical Grade 2 is still our top pick.
Permits, Rentals, and LA-Specific Rules
No permit needed for a standard deadbolt install on your own home. If you’re a tenant, California law lets you request a lock change from your landlord in specific situations — talk to them first. For rental property owners, LA housing code requires working deadbolts on primary entry doors of most rentals.
