When the Chicago winter arrives in Lake Forest, it brings more than just beautiful snow; it brings freezing temperatures that can wreak havoc on your home’s security. At J & R Lock & Safe, we have been safeguarding homes as professional locksmiths in Lake Forest, IL for over five decades. Established in 1975, our family-owned and locally operated team understands that Lake County winters require a proactive approach to home maintenance. Locks are mechanical devices that can easily seize, freeze, or fail when the mercury drops and moisture infiltrates the hardware. Taking a few simple steps now can prevent the stress of a broken key or a frozen latch on a sub-zero morning.
The Science of Frozen Locks and How to Prevent Them
Winter air in Illinois is often filled with moisture from snow and sleet, which can find its way into the tiny crevices of your door locks. When this moisture freezes, it creates ice crystals that block the internal pins and springs from moving, effectively jamming the mechanism. To prevent this, lubrication is your first line of defense. However, not all lubricants are created equal for the Lake Forest climate. You should avoid thick, oil-based products like standard grease, which can become "gunked up" and sticky in extreme cold. Instead, use a high-quality dry graphite or a specialized silicone-based spray.
These materials repel moisture and stay slippery even when temperatures fall well below zero, ensuring your key turns smoothly every time. Applying a small amount of lubricant directly into the keyway and working the key back and forth distributes the protection to all the moving internal parts.
Inspecting Your Door Alignment and Hardware
The cold doesn't just affect the lock itself; it also causes the materials around your door to shift. Wood frames and metal doors can contract in the cold, which often leads to misalignment between the deadbolt and the strike plate. If you find yourself having to push, pull, or lift the door handle to get the lock to engage, your home’s security is already compromised. Misalignment puts extra pressure on the locking bolt, which can eventually lead to a snapped key or a jammed motor in smart locks. Before the deep freeze sets in, check that your doors close flush and that the deadbolt slides easily into the frame. If things feel tight, a quick adjustment now is much easier than a late-night emergency repair.
Why Quality Hardware Matters in Harsher Climates
Not all locks are built to survive fifty winters in Northern Illinois. At J & R Lock & Safe, we partner with industry leaders like Medeco, Schlage, and Mul-T-Lock because their hardware is engineered for durability and weather resistance. Higher-end locks feature tighter tolerances and better seals that keep salt and ice out of the cylinder.
If you are still using builder-grade hardware, an upgrade to high-security locks or a modern access control system can provide better protection against the elements. Our licensed and insured professionals can help you select weather-rated hardware that combines aesthetic beauty with the rugged strength needed for our local climate.
