We understand the importance of maintaining a polished, professional appearance and work with hardware that matches the upscale environment.

Catherine S.

30 June 2025

We moved into our home in Frontenac Estates and wanted every lock in the house upgraded to high-security hardware. Nonstop Lock & Key came out, assessed all eight exterior entry points, and recommended a restricted keyway system so that keys cannot be duplicated without our authorization. The installation was meticulous and the technician even aligned the hardware to sit perfectly flush with our custom doors. Exceptional quality of work.

Wife locked her keys in the car at Plaza Frontenac. There in 20 min. Pro.

Discreet rekey of twelve doors plus the pool house on our estate. Respectful and meticulous.

Had a smart lock installed at our Frontenac Estates home that integrates with our existing security platform. Tech was knowledgeable about high-end systems and coordinated cleanly with our alarm company. Took the time to set up individual user profiles for the family and house staff. Highly professional.

Lost my key fob while running errands. Nonstop dispatched a tech to the parking lot, programmed a new fob for my Lexus right there. Fast, courteous, and the price was far lower than the dealership quote.

My elderly mother accidentally locked herself out of her home late on a Sunday. Nonstop got there quickly and made her feel calm during the whole process. Very respectful with her. Worth every dollar.

Manage a small office at Plaza Frontenac and needed a master key system after a partnership change. Nonstop set it up cleanly with restricted keyways, three levels of access, and pristine installation that matched our existing hardware finish. Worth the price for the discretion alone.
