Professional Lock Installation Process

Why Professional Installation Changes Everything

Poor installation ruins even the best locks. We see it constantly – expensive hardware that fails because someone cut corners on mounting, used wrong screws, or ignored door frame reinforcement needs. These locks look impressive but crumble under real pressure.

Our technicians have completed thousands of installations across Delaware County, PA. We understand how different door materials behave, which reinforcement methods work long-term, and what security upgrades your specific setup actually needs.

Every installation includes proper strike plate mounting with 3.5-inch screws that penetrate your door frame’s structural studs. We test every component before leaving and provide operation instructions so you understand exactly how your new security system works.

Complete Lock Installation Service

What's Included in Every Installation

We don’t just swap hardware and disappear. Every new lock installation begins with thorough evaluation of your door, frame, and existing security vulnerabilities. Some doors need reinforcement before new locks can provide real protection.

Your service includes complete removal of old hardware, professional mounting with proper alignment and reinforcement, security-grade strike plate installation, and comprehensive testing of all components. You receive new keys cut to exact manufacturer specifications and detailed operation instructions.

When your door requires additional reinforcement, weatherproofing, or frame repair, we handle those upgrades as part of creating a complete security solution. Our goal is reliable protection that works perfectly for decades, not quick fixes that fail when you need them most.

New Lock Installation FAQs

Common questions about our New Lock Installation services

Residential lock installation typically costs $150 to $350 per lock, depending on the lock type and installation complexity. Basic deadbolt installation starts around $100-200, while high-security or smart locks range from $300-500. This includes complete removal of old hardware, professional installation with proper reinforcement, new keys cut to specifications, and thorough testing. Many homeowners see insurance premium reductions of 2-5% that help offset the investment. We provide upfront pricing with no hidden fees, so you know exactly what to expect before we start work.
For front door security, we recommend Grade 1 deadbolts from Schlage, Kwikset, or Medeco that resist 250+ pounds of force and handle over 1 million cycles. Single-cylinder deadbolts work for most applications, while double-cylinder versions provide extra security for doors with nearby glass panels. Every installation includes reinforced strike plates with 3.5-inch screws anchoring into structural studs. Smart locks are increasingly popular for convenience while maintaining traditional key backup. We help you choose the right combination of security level, convenience features, and budget considerations for your specific needs.
Standard lock installation takes 30-60 minutes per lock, including old hardware removal, new lock mounting with proper alignment, strike plate reinforcement, key cutting, and complete testing. More complex installations involving door reinforcement, smart lock programming, or multiple security upgrades may require additional time. We always provide realistic time estimates upfront and work efficiently to minimize disruption to your daily routine while ensuring quality installation that provides reliable security for years. Rush jobs often lead to problems, so we focus on doing it right the first time.
Yes, we install all types of smart locks including keypad, Bluetooth, Wi-Fi, and biometric models throughout Delaware County, PA. Smart locks offer convenient features like remote access, temporary guest codes, and integration with home automation systems while maintaining traditional key backup for power outages. Installation requires additional setup time for programming and app configuration. We help you select models that match your technical comfort level and security requirements, from basic keypad locks to fully integrated smart home systems. Our experience ensures proper installation and reliable operation.
The decision depends on your current lock quality and security goals. Rekeying costs $80-150 and works well if your existing locks are high-quality, properly functioning, and meet current security standards. However, new installation is better if your locks are old, damaged, low-grade, or if you want significant security upgrades. New locks also allow you to improve finishes, add smart features, or upgrade to higher security grades. We’ll assess your current hardware and help you determine which approach provides the best value for your specific situation, budget, and security needs.
We’re authorized dealers for Schlage, Kwikset, and Medeco – three of the most trusted names in residential security. Schlage offers excellent durability and advanced security features, Kwikset provides reliable performance with good value, and Medeco specializes in high-security applications for maximum protection. All these brands meet or exceed ANSI Grade 2 standards for residential use. We stock various styles and finishes to complement your home’s appearance while providing the security level you need. Our experience with thousands of installations across Delaware County helps us recommend the best brand and model for your specific requirements.
