Fast, Reliable Lock Installation & Rekey Across South Gate
Lock installation and rekeying in South Gate usually runs $65-$180 per cylinder or lock, and most jobs are completed the same day. Novak Lock & Security has worked on hundreds of South Gate homes, and we know the two-door problem better than anyone: the aging wooden bungalow door, and the custom-welded wrought-iron security door in front of it. If you need a rekey, a smart lock install, or a lock that finally stops seizing up every fall, call (331) 310-8471 and we’ll quote a firm price in writing before anyone is dispatched.
Why Novak Lock & Security Is South Gate’s Preferred Lock Installation & Rekey Company
South Gate homeowners call us because we speak the language of their houses. The compact 1940s-1960s bungalows between Long Beach Boulevard and Atlantic Avenue weren’t built for modern lock hardware, and the decorative reja in front of nearly every front door was rarely built for any hardware at all. Our technicians carry security-door-specific cylinders, shims, and reinforcement plates that most locksmiths don’t stock, because in South Gate, those aren’t specialty items. They’re the job.
Every South Gate visit is handled by a background-checked, uniformed technician working under The Haven Standard. The dispatcher quotes a firm price on the phone, and Haven Standard Clause 1 is simple: the price on the phone is the price on the invoice. No technician is permitted to change it at the door. Since 2002, that rule has been the entire foundation of this company. We leave a documented photo record of every job, and every lock installation or rekey is covered by our 365-Day Done Right Promise. If it’s not done right, we make it right.
Daniel Novak, the owner, built this business on written pricing because he’d watched too many South Gate and Southeast LA homeowners get quoted one number over the phone and handed a different invoice at the door. That doesn’t happen here. It can’t. The rule has been in place for over two decades.
Our Lock Installation & Rekey Services in South Gate

Our Lock Installation & Rekey team handles everything from a single deadbolt swap to a full home rekey with high-security cylinders. In South Gate, that work almost always involves two doors per entry, and our process accounts for both from the first phone call.
Smart Lock Installation
A smart lock retrofit on a 1950s South Gate bungalow is rarely a direct swap. The original jamb widths are often non-standard, the strike sits in a soft or split frame, and the door itself has settled out of square. We reinforce the jamb, shim the strike to correct alignment, and install the smart lock so the deadbolt throws cleanly without binding. We work with Schlage, Yale, and Baldwin smart hardware, and every install comes with a written scope and a documented photo record.

Keyless Entry
Keyless entry systems are practical for South Gate households where multiple generations share a front door, and for rental properties where key control matters. We install keypad and electronic entry systems on both wooden main doors and reja security doors, which is where the job gets interesting. Many local rejas were fabricated by small welding shops, and their lock cutouts don’t match any modern keypad footprint. We cut, fit, and reinforce as needed, rather than telling you the door can’t accept the hardware.

Keypad Lock
Standalone keypad locks are a straightforward upgrade for the main door, but the South Gate climate works against them if the wrong finish is used. Black powder-coated keypads hold up well in the dry heat. Cheap zinc housings don’t, especially with the salt air that drifts inland from the coast. We steer South Gate customers toward marine-grade or stainless finishes when the lock will sit within a few blocks of the 710 corridor or in an exposed south-facing entry.

Biometric Lock
Fingerprint and biometric entry locks are becoming common in South Gate for home offices, ADU conversions, and detached garages. The installation is the same story as every other modern lock here: the old jamb and frame need work before the new hardware goes on. We fit the strike, check the reveal, and confirm the latch engages without pressure. A biometric lock that fights the frame will fail its motor or drain its battery in months. We install it so it doesn’t.

Key Duplication
South Gate homeowners often need copies of keys that big-box key cutters can’t duplicate: oddball reja cylinder keys, high-security Medeco and Mul-T-Lock blanks, and worn originals that barely turn. We duplicate standard and high-security keys on-site from our mobile workshop, and we can originate new keys from code when the original is too worn to copy accurately.

Trusted Brands We Service in South Gate
We’re factory-authorized on Medeco, Mul-T-Lock, Abloy, Baldwin, and Schlage, and we service Yale and Kwikset as well as the oddball barrels found in custom South Gate rejas. That last category is the one that matters most around here. If your security door was welded by a local fabricator in the 1980s, there’s a good chance its cylinder is discontinued or proprietary. We carry a broad assortment of rim cylinders, security-door-specific tailpieces, and marine-grade stainless components on the truck, so a rekey on a custom reja doesn’t turn into a two-week parts hunt.
Common Lock Installation & Rekey Problems We See in South Gate Homes

- Seized reja cylinders from salt air. Standard steel lock cylinders corrode within a few seasons near South Gate’s coastal air. Keys snap off or refuse to turn, and the fix is a stainless marine-grade rim cylinder, not a shot of WD-40.
- Seasonal frame binding from Santa Ana winds. Every fall, dry winds shrink the wooden frames of 1940s-1960s bungalows and deadbolts start grinding against their strikes. A rekey alone won’t fix it. The strike needs shimming or repositioning, and the frame often needs reinforcement.
- Non-standard jamb widths on original doors. Many South Gate bungalows still have their original 2¼-inch or 2⅜-inch jambs, and modern smart locks assume a 2¾-inch standard. We build out or reinforce the jamb so the new hardware sits correctly.
- Worn original mortise locks. The main door on a 1952 South Gate home frequently still carries its original mortise lock body. The internal springs and levers are tired, and the keyway is so worn that bumping is a real risk. We rekey to bump-resistant Schlage pin and tumbler cylinders or replace the mortise body entirely when it’s beyond service.

FAQs - Lock Installation & Rekey in South Gate

The dry Santa Ana winds that sweep through South Gate each fall shrink the wooden door frame behind your reja, and the security door’s own steel frame flexes with the temperature swing. The cylinder binds because the strike has shifted out of alignment. We shim or reposition the strike, and if the cylinder itself shows internal corrosion from salt air, we swap it for a stainless marine-grade rim cylinder. Call (331) 310-8471 and we’ll diagnose it over the phone.
Yes. We keep a broad assortment of rim cylinders, tailpieces, and security-door-specific hardware on the truck precisely because so many South Gate rejas were built with proprietary or discontinued barrels from small local fabricators. If your existing cylinder can’t be rekeyed, we’ll replace it with a stainless marine-grade unit that fits the door’s cutout and matches the finish of the surrounding ironwork.
We specify marine-grade stainless steel or solid brass hardware for exterior locks in South Gate, and we avoid standard zinc or bare steel components that corrode within a few seasons of coastal air exposure. The finish matters less than the substrate. A stainless lock body with a good weather seal will outlast a painted zinc lock by years. We’ll tell you which of the brands we stock make sense for your specific exposure.
Yes, and this is one of the most common jobs we do in South Gate. We reinforce the jamb with a steel strike plate and longer screws into the stud behind the frame, repair or fill the split section, and re-mortise the strike pocket if the original is blown out. The smart lock then sits and cycles correctly. A smart lock bolted to a failing frame is a motor burnout waiting to happen, so the frame work is part of every install here, not an add-on.
Expect $130-$245 total for both doors, depending on whether the reja’s barrel can be rekeyed or needs a full cylinder replacement. A standard main-door rekey runs $65-$95, and a reja cylinder replacement runs $85-$150. We quote the exact number on the phone before we send a technician, and that number is what you pay. No call-out fee, no doorstep adjustment. Call (331) 310-8471.
If you live in a South Gate bungalow with a reja out front, you know the two-door reality better than most. The main door swells and shrinks with the seasons, and the security door’s lock fights the salt air every year. We fix both, in one visit, with hardware that survives the local conditions. Call (331) 310-8471 for a free, written estimate on any lock installation or rekey in South Gate. Daniel Novak’s name is on the van and the invoice, and the price is set before we leave the phone.
