Your doors and windows are your home’s first line of defense—yet they are also the most common entry points for intruders. Many properties are left vulnerable with outdated or poorly fitted locks. Gronbek Security offers high-quality door and window lock solutions designed to withstand attempts at forced entry while meeting insurance requirements. Our locksmiths assess your property, recommend the best lock types, and install them with precision. From deadlocks and solid-core door solutions to child-safe and compliant window locks, our products ensure you, your family, and your belongings are protected.

Have you ever wondered who might still have a key to your home? Previous owners, tenants, or contractors may still hold access you don’t know about. Rekeying eliminates this hidden risk without needing to replace entire locksets. Gronbek Security’s expert team can rekey your locks quickly and affordably, ensuring only new keys work moving forward. We also provide full replacement services when a lock has worn out, been damaged, or no longer offers the level of protection you need. With Gronbek, you take back control, knowing exactly who can access your property.

Modern living demands smarter solutions. Lost keys, spare copies, and physical access risks can all be avoided with smart locks and keyless entry systems. Gronbek Security supplies and installs the latest electronic locking technology—allowing you to control entry with codes, cards, or even your smartphone. Ideal for both homes and businesses, these systems let you track access, grant temporary codes to visitors, and remove access instantly without replacing hardware. Secure, convenient, and designed for the future, our keyless entry solutions put you in complete control of who enters your property, and when.

An alarm isn’t just a noise-maker—it’s your home’s constant guardian. Many households still rely on outdated systems that fail to provide adequate coverage or integration. Gronbek Security delivers advanced alarm systems with full smartphone integration, so you can monitor and manage your home’s protection anytime, anywhere. From motion detection to door and window sensors, we tailor systems to fit your property and lifestyle. Stay informed in real time with instant alerts to your phone, and enjoy the confidence of knowing your home is protected—even when you’re not there.
