"We understand your concern regarding the smart door knob installed nearly six months ago, and we appreciate the opportunity to clarify the matter. The original installation was completed per your request for a "keyless access system." At the time of installation, the lock was fully functional, and we have video documentation confirming it was working properly. (October /2024) The issue you reported "difficulty with the fingerprint sensor in cold weather" is a product-related concern, not an installation issue. We advised you to reach out to the manufacturer for further assistance, as this falls under their warranty and product support. However, in an effort to accommodate your concerns, we offered a solution: removing the smart lock and replacing it with a passage door knob. To further assist you, we even offered a **discounted rate** for the labor and materials involved in this installation. Despite these efforts, you declined to cover the cost and are now requesting a $70 refund. Given that the installation was completed successfully and functioned properly for several months, we find this request to be unfair to our company. Additionally, with multiple individuals using the door daily over an extended period, it is unclear whether the issue stems from the product itself or other factors beyond our control. Our goal is always to provide high-quality service and customer satisfaction. However, product performance over time is ultimately the responsibility of the manufacturer, not the installation provider. We remain available to assist with further solutions at a fair and reasonable cost."

"Thanks it was a pleasure meeting you!"
