Our Lock Installation & Rekey Services in Dunellen
Smart Lock Installation
Smart locks make sense for Dunellen’s two-family landlords who need to manage access remotely, and for homeowners who want to ditch keys after a flood loss. We install Yale and Schlage smart deadbolts that integrate with existing hardware, so you’re not rebuilding your door from scratch. Post-Ida renovations often left homes with cheap knob-lock-only setups - we retrofit proper smart deadbolts that actually secure the door, not just automate a weak point. Wi-Fi connectivity, app control, and temporary access codes for tenants or contractors are all configured on-site. Typical smart lock installation in Dunellen runs $220-$340 including hardware and labor.
Keyless Entry
Keyless entry systems eliminate the key management headache for Dunellen’s many two-family properties, where landlords and tenants currently juggle overlapping key sets. We install keypad and push-button entry systems from Schlage and Baldwin that stand up to the Raritan Valley’s humidity - a real factor here, where moisture corrodes standard lock internals faster than in drier inland towns. For the flood-remediated blocks near the borough center, we specify corrosion-resistant finishes and stainless steel bolts that won’t bind in swollen jambs. Keyless entry installation in Dunellen typically costs $180-$290.
Keypad Lock
Keypad locks bridge the gap between traditional keyed entry and full smart home integration. They’re popular with Dunellen’s older homeowners who want convenience without complexity - no phone app required, just a code you can change yourself when a tenant moves out. We install commercial-grade keypad deadbolts from Sargent and Yale that fit the door prep on most Dunellen homes, including the post-renovation doors where contractors used non-standard backsets. When the wood jamb has shifted from prior water damage, we adjust the strike and reinforce the frame so the bolt throws clean every time. Keypad lock installation runs $190-$310 in Dunellen.
Biometric Lock
Biometric locks - fingerprint readers - are gaining traction among Dunellen homeowners who’ve had keys lost in flood evacuations or simply want one less thing to carry. We install Mul-T-Lock and Yale biometric deadbolts that store multiple fingerprints, ideal for two-family setups where both landlord and tenant need access. These units require precise door prep and clean power; we handle the full installation including battery backup and low-battery alerts. On Dunellen’s older homes with original mortise pockets, we sometimes need to custom-fit the mounting - work that cheaper operators skip, leaving you with a lock that looks right but doesn’t secure. Biometric installation in Dunellen: $280-$420.

Trusted Brands We Service in Dunellen
We stock and install Schlage, Yale, Baldwin, Mul-T-Lock, and Sargent hardware - brands that hold up in Dunellen’s demanding conditions. After Hurricane Ida, we saw too many flood-remediated homes get fitted with no-name knob locks that corroded within two seasons. We keep Schlage B60 deadbolts and Yale Assure smart locks on our trucks because they’re the units we trust in humid, flood-prone environments. Parts are available, warranties are real, and when something fails, we can fix it fast instead of ordering obscure components. That’s the difference between a locksmith who installs what they have and one who installs what you need.
Common Lock Installation & Rekey Problems We See in Dunellen Homes
- Builder-grade knob-lock-only setups on post-flood renovated homes. Contractors rebuilding after Ida often installed Kwikset knob locks with no deadbolts to save time and money. Ground-floor entrances are left vulnerable. We retrofit proper deadbolts - usually Schlage B60s with stainless steel bolts - and reinforce the jamb so the lock actually functions as security, not decoration.
- Swollen jambs preventing deadbolts from throwing fully. Dunellen’s humid climate and prior flood exposure cause seasonal wood movement in older door frames. A deadbolt that worked in March binds by August. Simple rekeying won’t fix this - we replace the hardware with corrosion-resistant plating and often adjust the strike plate or plane the jamb so the bolt seats clean.
- Original mortise locksets on pre-1920s homes requiring specialty parts. The vintage housing stock near the train station and along the borough’s older cross-streets still has skeleton-key mortise locks. Standard Kwikset or Schlage replacements don’t fit the rectangular pocket. We source specialty parts or fabricate custom modifications - work that takes time and skill, not a quick swap.
- Two-family conversions needing separate master-key systems. A single Dunellen address often houses landlord and tenant with overlapping access needs. We rekey to master systems where the landlord carries one key for all locks, tenants carry keys for their unit only, and neither set compromises the other. This requires precision pinning and documented key hierarchies - not a hardware-store rekey kit.

FAQs - Lock Installation & Rekey in Dunellen
Yes. Post-Ida rebuilds in Dunellen frequently got contractor-grade knob locks with no deadbolts, especially on lower-lying streets near the borough center. Ground-floor doors without deadbolts are a known vulnerability. We retrofit Schlage B60 deadbolts with stainless steel bolts that resist corrosion in humid conditions, and we reinforce jambs that may still carry moisture damage. Call (877) 691-7931 for a free assessment of your rebuilt doors - estimates are free.
You likely need hardware replacement, not just rekeying. Dunellen’s humid climate and prior flood exposure cause seasonal wood swelling in older jambs; the bolt binds in the distorted frame rather than the cylinder failing. Rekeying won’t solve a mechanical binding issue. We install deadbolts with corrosion-resistant plating and adjust the strike or jamb so the bolt throws freely year-round. Call (877) 691-7931 - we’ll diagnose it on-site and quote upfront.
Yes. We build master-key systems where your key opens all locks, your tenant’s key opens only their unit, and neither compromises the other. This is standard work for Dunellen’s many two-family conversions, though it requires precision pinning beyond a basic rekey. We document the hierarchy and test every combination before leaving. The typical two-family master system runs $160-$250. Call (877) 691-7931 to schedule - we can often same-day this.
Sometimes. Original mortise locksets on pre-1920s Dunellen homes require specialty skeleton-key parts that are increasingly hard to source. When parts are available, we rekey. When they’re not, we fabricate custom modifications or replace with modern hardware that fits the existing pocket - never a destructive retrofit that damages your vintage door. Mortise work runs $180-$290 depending on complexity. Call (877) 691-7931 and we’ll assess what you’ve got.
Yes. We install Yale and Schlage smart deadbolts that integrate with existing Schlage keyed hardware, so you’re not replacing everything. For Dunellen’s post-flood renovations, we often pair smart locks with reinforced deadbolt retrofits - the smart feature is only as good as the physical security behind it. Wi-Fi setup, app configuration, and temporary access codes are included. Smart lock installation runs $220-$340. Call (877) 691-7931 for an exact quote - estimates are free.
We recently rekeyed a post-renovation two-family on South Washington Ave where the contractor had installed Kwikset knob locks with no deadbolts, standard in flood-remediated rebuilds. Because the wood jamb had swollen from prior water damage, we upgraded to Schlage B60 deadbolts - the stainless steel bolt resisted binding in the distorted frame - and set up separate master-key systems for the landlord and first-floor tenant. That’s the kind of job we do in Dunellen: not just changing a cylinder, but solving the problem the last guy left behind.
