Fast, Reliable Lock Installation & Rekey Across Paramount
Lock installation and rekeying in Paramount typically runs $89-$280 for residential work, with most jobs completed same-day and emergency calls answered live within two rings. If you’re standing at a door that won’t lock on Somerset Avenue or managing turnover at a fourplex near Downey Avenue, we’ll quote a flat price before the truck rolls and show up when we say.
We’ve worked Paramount’s 90723 ZIP for decades. We know the 1940s stucco bungalows with their lightweight frames, the duplexes off Colorado Avenue, and the small warehouses lining Santa Fe Avenue’s industrial corridor. That local knowledge matters because a lock that works in a new-build frame often fights an older Paramount door. Our technicians carry the shims, strike-plate extenders, and reinforced hardware to make modern deadbolts fit right on doors that have seen seventy years of service.

Our Lock Installation & Rekey Services in Paramount
Smart Lock Installation
Paramount’s landlords and longtime homeowners are increasingly asking for smart locks, but the installation rarely goes straight out of the box. Those 1950s door frames on Colorado Avenue and Somerset Boulevard don’t always accommodate the thicker smart deadbolt assemblies without shimming or bore adjustment. We install Schlage Encode, Kwikset Halo, and Yale Assure models regularly, and we know which ones tolerate Paramount’s frame shrinkage better than others. A smart lock on a checked frame needs precise throw alignment or it’ll bind every August when the wood contracts. We measure twice, install once, and show you how to manage access codes before we leave.
Keyless Entry
Keyless entry systems solve the turnover problem that defines Paramount’s rental market. If you’re managing units on Downey Avenue or Malden Street, you know the cost of rekeying between tenants adds up fast. A keypad lock eliminates that cycle. We install mechanical and electronic keyless sets from Schlage and Kwikset that fit Paramount’s older bores without drilling new holes. For the industrial spaces along Santa Fe Avenue, we also source heavy-duty keypad deadbolts and lever sets that stand up to warehouse traffic. Flat price quoted on the phone. Same-day installation most days.
Keypad Lock
Standalone keypad locks remain the most requested upgrade in Paramount’s small apartment buildings. They’re simpler than full smart locks, require no Wi-Fi, and let landlords issue new codes instead of new keys. We see this most on the duplexes and fourplexes near the intersection of Somerset and Alondra, where absentee owners need remote management without remote complexity. Our keypad installations include strike-plate reinforcement because Paramount’s thin original frames need the extra support. We stock Schlage and Kwikset keypad models locally, so most Paramount customers get same-day service.
Biometric Lock
Biometric locks fingerprint-recognition deadbolts and levers are gaining traction among Paramount’s small-business owners, particularly in the light-manufacturing shops along Santa Fe Avenue where key control is a constant headache. These units demand precise installation: the sensor must sit flush, the bolt must throw true, and the frame must be stable enough to maintain alignment. Paramount’s seasonal frame movement makes professional fitting essential. We install Medeco and Schlage biometric units, and we’ll tell you honestly if your door is a candidate or if a keypad better suits your situation.
Electronic Lock
Electronic locks bridge the gap between traditional deadbolts and full smart-home integration. In Paramount, we install these most often on mixed-use properties: residential units above, small commercial below, common entries that need audit trails. The electronic locks we source from Schlage and Yale offer key override, code management, and low-battery warnings. For Paramount’s older buildings, we pay special attention to power source routing and strike-plate security, since a fancy lock on a weak frame is no lock at all.
Key Duplication
Key duplication seems simple until you’re holding a worn Kwikset key from a 1960s Paramount rental that no big-box machine can read. We duplicate keys by code and by sight, including high-security Medeco and Schlage Primus keyways that require specialized equipment. For landlords managing multiple units, we can key alike compatible locks or master-key small buildings. Our Paramount shop stocks blanks for the brands we install, so most duplicates are ready while you wait. Seniors and veterans receive our standing 5% discount on all key duplication.

Trusted Brands We Service in Paramount
We install and service Schlage, Kwikset, and Medeco hardware in Paramount, with local parts inventory that keeps most jobs single-visit. Schlage’s commercial-grade deadbolts handle the warehouse traffic on Santa Fe Avenue. Kwikset’s SmartKey cylinders let landlords rekey themselves between tenants, a popular option on Downey Avenue rental properties. Medeco’s high-security keyways serve the customers who’ve had unauthorized copies made one too many times. We don’t push what’s on the truck. We match the lock to the door, the budget, and the actual security need. That means faster turnaround for Paramount customers and no return trips for wrong parts.
Common Lock Installation & Rekey Problems We See in Paramount Homes
- Cylinders worn past function from decades of landlord rekeying. Paramount’s rental stock has been rekeyed repeatedly since the 1970s. The original Kwikset and Schlage cylinders in these units often reach a point where pins no longer seat cleanly and keys hang up. At that stage, rekeying won’t help. We replace the cylinder or the full lockset, depending on frame condition and your budget.
- Thin door frames shrinking in dry heat, throwing deadbolts out of alignment. The LA Basin’s dry summers cause Paramount’s original wood frames to contract, often by an eighth-inch or more. The deadbolt throw misses the strike plate, jams, or requires shoulder pressure to turn. We see these calls spike every August and again in January after winter rains swell the frames back. Proper shim work and adjustable strike plates solve it.
- Hollow-core interior doors with passage sets providing no real security. Many Paramount rentals have hollow-core bedroom and bathroom doors with simple passage latches, not privacy locks. Tenants and owners alike want keyed entry or at least push-button privacy. We upgrade these to proper privacy sets or keyed locks where requested, though we’ll note honestly when the door itself is too lightweight for meaningful security.
- Commercial roll-up door hardware failing on Santa Fe Avenue warehouses. The industrial corridor’s padlocks, hasp-and-staple setups, and roll-up door cylinders take more abuse than residential hardware. We replace these with commercial-grade Abloy padlocks and reinforced hasps that survive forklift traffic and outdoor exposure.

FAQs - Lock Installation & Rekey in Paramount
Yes, this is one of our most frequent calls in Paramount, especially in late summer. The dry heat shrinks the thin original door frames common to 1940s-1960s rentals, causing the deadbolt throw to misalign with the strike plate. A rekeying job doesn’t address frame geometry. We shim the strike plate, check the bore alignment, and often install longer reinforced screws so the hardware stays put through the seasonal cycle. Call (877) 664-8139 for a free estimate - we’ll diagnose it over the phone and quote flat.
Schlage Encode and Kwikset Halo tolerate Paramount’s frame variation better than most, but the real answer depends on each door’s bore depth and backset. Older Paramount doors often need 2-3/8″ backsets and sometimes bore enlargement for smart lock housings. We carry both brands locally and measure on-site before recommending. For absentee management, we also set up remote access and show you code management. Call (877) 664-8139 to schedule a walk-through of your Downey Avenue properties.
Almost always, yes. We recently rekeyed and upgraded the locks on a 1950s duplex on Somerset Avenue near the industrial corridor. The original Kwikset cylinders were worn past reliable function from decades of landlord rekeying, and the thin door frames had checked in the heat, requiring us to shim the strike plates and install Schlage deadbolts with reinforced strike screws to restore proper throw alignment. Colorado Avenue frames are built the same way. We’ll make your deadbolt fit and function, backed by our 90-Day Done Right Promise. Call (877) 664-8139 for a flat quote.
Yes. We carry Kwikset SmartKey and standard Schlage pinning kits, plus Medeco and high-security keyways. For a Malden Street fourplex, we’ll likely key-alike compatible units to reduce your key count, or master-key the building if you prefer separate unit access with a single master. We quote the full job flat before we start, and we work around tenant schedules. Call (877) 664-8139 to set up the rekey.
Yes, and this is specialized work we do regularly in Paramount’s industrial corridor. We install Abloy padlocks and reinforced hasp-and-staple hardware rated for outdoor exposure and warehouse traffic. Roll-up door cylinders and slide bolts are also in our standard inventory. We’ll assess your door gauge and frame backing, then quote flat for hardware plus installation. Call (877) 664-8139 - we stock commercial-grade parts locally for same-day service on Santa Fe Avenue.
