The city's harsh winters, humid summers, and frequent temperature swings can cause locks to warp, stick, or break. Andrew Patio Door Lock Repair understands these local conditions because we work in Chicago neighborhoods every day. We don't just fix locks—we ensure your patio door functions smoothly and securely through every season. Our team uses industry-tested techniques and tools to diagnose and resolve issues quickly. Whether it's a misaligned strike plate, a worn cylinder, or a key that won't turn, we focus on precision. We respect your time and property, arriving prepared with the right equipment to avoid unnecessary delays. No guesswork, no shortcuts—just reliable work that holds up to Chicago's demands. ## The brands we service in Chicago We work with a wide range of residential lock brands commonly found on Chicago patio doors. Our experience includes Schlage, Yale, Kwikset, Medeco, Mul-T-Lock, Assa Abloy, Baldwin, Weiser, Master Lock, and Sargent. Each brand has its own design and security features, and we know how to service them properly. For example, Schlage and Baldwin are popular on older Chicago homes, while Kwikset and Weiser are common in newer constructions. Medeco and Mul-T-Lock offer high-security options for homeowners who prioritize extra protection. Assa Abloy and Sargent are often found in multi-unit buildings or custom installations. Whatever brand you have, we can repair or replace it without compromising security. ## Professional equipment & materials we use Our work relies on professional-grade tools and materials. We carry key cutting machines to duplicate or create new keys for most patio door locks. For lockouts or stubborn mechanisms, we use pick guns, tension wrenches, plug spinners, and locksmith decoders to open locks without damage. Key extractors and bore scopes help us remove broken keys or inspect internal components. A drill press and impressioning files allow us to craft replacement parts when needed. Lishi tools are useful for decoding and picking specific lock types quickly. For materials, we use brass, steel, and titanium keys depending on durability needs. Lock pins, springs, screws, cylinders, deadbolts, padlocks, and door strikes are all sourced from reputable suppliers. We match materials to your existing hardware to ensure compatibility and longevity. No generic parts that might fail in a Chicago winter. ## The standards and safety codes we work to We follow recognized industry standards to ensure every repair meets safety and performance requirements. Our work aligns with ANSI/BHMA A156.2 for bored and preassembled locks, ANSI/BHMA A156.5 for cylinder locks, and ANSI/BHMA A156.13 for deadbolts. These standards cover strength, durability, and security. For fire safety, we adhere to NFPA 80, which governs the installation and maintenance of fire doors. ADA Standards are considered when accessibility is a concern. UL 437 applies to high-security locks, and ASTM F883 covers padlocks. We also follow ISO 9001 quality management principles in our processes. Team members hold BHMA certifications and ALOA Professional Certification, demonstrating our commitment to ongoing training and expertise. We don't cut corners on codes. Every lock we repair or replace is installed to function correctly and safely, giving you peace of mind. Call Andrew Patio Door Lock Repair today to schedule a service visit.
