That slow, heavy swing on your storefront door is telling you something. 🚪

When a door closer starts leaking fluid, slamming shut, or letting the door drift open, it is more than an annoyance. It can wear out your lock, strain the frame, and leave your business less secure at closing time. Our commercial locksmith team installs, adjusts, and replaces door closers on glass and aluminum doors for shops, offices, and retail spaces around Ann Arbor. We make sure your door closes smoothly, latches properly, and meets code.

✔ Door closer installation and adjustment
✔ Panic bars and exit devices
✔ High-security locks and master key systems

While many know us as an auto locksmith for car key replacement, our 24 hour locksmith crew also handles commercial work of all sizes. And if a door or lock problem shows up after hours, our emergency locksmith team is ready to help. Reach out to CS Lock and Key today for a free quote and keep your entryway working the way it should.
