Our Lock Installation & Rekey Services in Northglenn
Smart Lock Installation
Northglenn’s 1960s ranch homes weren’t built for WiFi-enabled deadbolts, but that doesn’t mean they can’t accept them. The challenge is matching modern smart locks to legacy door prep - older backsets, non-standard handing, and hollow-core doors that need strike-plate reinforcement before they’ll support the torque of a motorized bolt. We install Schlage Encode and Yale Assure locks regularly in Northglenn, and we carry the reinforcement hardware to do it without damaging original trim. Most smart lock installations in Northglenn run $280-$450 including labor, reinforcement, and setup on your phone.

Keyless Entry
Keyless entry systems are popular with Northglenn homeowners who rent out basement units or want to stop hiding keys under the mat. We install keypad levers and deadbolts that fit the city’s standard residential prep, and we can key them alike to existing Schlage or Kwikset systems where the hardware allows. For the rental market near 120th Avenue and the original ranch courts off Huron Street, keyless entry means no more rekeying between tenants - just a code change. Typical keyless entry installation in Northglenn: $220-$380.

Keypad Lock Installation
Keypad locks bridge the gap between traditional keyed entry and full smart-home integration. They’re mechanical or electronic, battery-powered, and they don’t require WiFi - a practical choice for Northglenn’s older homes where router placement can be spotty. We recommend Medeco and Schlage keypad models for the Front Range climate, since the electronics are sealed against the dust and temperature swings that come with 40°F day-night differentials. A keypad lock install in Northglenn typically costs $200-$350.

Biometric Lock Installation
Biometric locks - fingerprint readers - are less common in Northglenn’s residential market, but we install them for homeowners who want maximum access control without carrying anything. The technology has improved; modern units from brands we trust will read a dry or cold finger, which matters here during heating season. Biometric installation runs higher due to the precision required: $350-$550 in the Northglenn market.

Trusted Brands We Service in Northglenn
We stock and install Schlage, Kwikset, Medeco, and Yale hardware from our local inventory, which means most Northglenn jobs don’t wait on parts. That’s critical for a city where so many homes share the same aging hardware - when we find a failed Kwikset 400-series cylinder on one block, we know the neighbors may need the same part. We also carry Mul-T-Lock and Baldwin for homeowners who want upgrade security without changing door prep. If you’re in 80241 and need a specific finish to match existing hardware, we source it fast.
Common Lock Installation & Rekey Problems We See in Northglenn Homes
- Undersized strike plates on hollow-core doors. The original 1960s hardware in Northglenn’s ranch homes used lightweight strike plates with short screws that barely bite the jamb. Modern deadbolts need deeper anchoring and often a reinforced strike box. We see this on almost every lock replacement call east of Washington Street.
- Seasonal binding from wood frame expansion. Northglenn’s 40-50°F day-to-night temperature swings, especially in spring and fall, cause door frames to shift enough that deadbolts drag or won’t fully extend. It’s not the lock failing - it’s the geometry changing. We diagnose this correctly instead of selling you hardware you don’t need.
- Wrong backset or handing on smart lock orders. Homeowners in Northglenn order smart locks online and discover their 1960s door prep uses a 2-3/8″ backset when the lock requires 2-3/4″, or the handing is reversed for a left-swing door. We measure before we quote and carry adapters when they’ll work safely.
- Original Kwikset cylinders worn to the point of key duplication failure. After 50-60 years of use, the pin chambers in Northglenn’s original locks are so worn that new keys won’t mate properly. Rekeying becomes unreliable; replacement is the honest recommendation.

FAQs - Lock Installation & Rekey in Northglenn
Yes, it’s normal for Northglenn’s climate, but it’s fixable. The Front Range’s spring temperature swings cause wood door frames to expand and contract, which throws deadbolt alignment out of spec. We adjust the strike or shim the hinges rather than replace the lock - an honest diagnosis that saves you money. Call (877) 664-8139 and we’ll check it during a free estimate.
Sometimes, but not always. Northglenn’s original door prep often uses a 2-3/8″ backset and smaller bore holes than current smart locks require. We measure your existing prep on the first visit and carry adapters or reinforcement plates that let us use the existing holes when possible. If new holes are needed, we drill clean and cover with escutcheons that match your trim.
Schlage and Yale smart deadbolts perform well when paired with our strike-plate reinforcement. For keyed hardware, Medeco’s high-security cylinders fit Kwikset and Schlage formats without changing the exterior look. The key is reinforcing the jamb first - a heavy lock on a weak door is security theater, not security.
Rekeying is cost-effective if the lock body and bolt are still sound. But in Northglenn’s 1960s housing stock, we often find cylinders so worn that new keys won’t seat reliably, or internal springs fatigued to the point of failure. We inspect before we recommend - if rekeying is the right call, we’ll do it. If replacement is honest, we’ll tell you that too.
Yes. We install Schlage Encode and Yale Assure locks that connect to Alexa, Google Home, Apple HomeKit, and Z-Wave hubs. For Northglenn’s older homes, we verify WiFi signal strength at the door before quoting and can recommend mesh extenders if needed. Integration setup is included in our installation price.
