Emergency Services
Yes, we do. Emergencies don't wait for business hours, and neither do we.

Call us at 636-942-6818 and a real person will answer, no matter the time of day or night. We'll dispatch a technician to your location as quickly as possible to get you back on track.

Any situation where your security or access is compromised can be considered an emergency. Common scenarios we handle include:

  • Residential or commercial lockouts
  • Broken or jammed locks that can’t be secured
  • Lost or stolen keys requiring immediate rekeying
  • Damaged locks or door frames after a break-in attempt
  • Malfunctioning access control systems preventing entry or exit

If you’re ever unsure, don’t hesitate to call. It’s better to check than risk leaving your home or business unsecured.

At Commercial Safe and Lock, your safety is never just a transaction — it’s our responsibility. We’re here to answer your questions, address your concerns, and make sure you feel completely secure every step of the way.
Home Security Questions​

Once your system is installed and activated, it is connected to our 24-hour professional monitoring center. If any sensor, camera, or detector on your system is triggered — whether it's a motion detector, smoke alarm, carbon monoxide alert, or door sensor — our monitoring team is notified immediately. We'll attempt to contact you first, and if we can't reach you or the situation calls for it, we'll dispatch the appropriate emergency services (police, fire, or medical) to your home without delay.

Yes. All of our home security systems are built with smart home integration in mind, allowing you to manage everything from a single app on your smartphone or tablet. You can arm and disarm your system remotely, view live and recorded camera footage, lock or unlock smart doors, receive real-time alerts, and even control smart thermostats and outlets — all from wherever you are in the world.

We believe security should be accessible and stress-free, not locked behind complicated agreements. Contact our team directly to discuss monitoring plan options that fit your needs and budget. We're upfront about everything — no hidden fees, no confusing fine print.

Absolutely. One of the things that sets CSL Services apart is our commitment to building security solutions that actually fit your lifestyle and your home. You won't be forced into a pre-bundled package loaded with things you don't need. We'll assess your property, listen to your concerns, and recommend the right combination of devices — whether that's a basic starter system or a fully integrated smart home security setup. You can always add more devices down the road as your needs evolve.

Our security systems are designed with backup power in mind. In the event of a power outage, your system will continue to operate on battery backup, ensuring your home remains protected even during blackouts. Our monitoring service will also alert you if your system loses power, so you're never left in the dark — literally or figuratively.
Technician & Security Questions
We take your safety and peace of mind seriously, which is why we have a clear identification process for every service call. All of our technicians arrive in full company uniform and drive marked company vehicles. Before your appointment, you will be notified in advance of your technician's name and their estimated arrival time. If anything seems off or you have any doubt, don't hesitate to call our office directly at 636-282-5625 to verify.
Yes. All CSL Services employees go through a thorough vetting process, including background checks, before joining our team.

You can feel confident that the person we send is someone we trust completely.
Warranties & Satisfaction Guarantee​
We stand behind everything we do — that's our promise. Commercial Safe and Lock offers a satisfaction guarantee on all of our work. If you're not completely satisfied with the outcome of any service we perform, we will make it right at no additional cost to you.

If you ever experience an issue with a device or component, let us know and we will coordinate directly with the manufacturer to resolve the problem as quickly as possible.
If a product installed by our team experiences a malfunction or defect, contact us right away. We'll assess the issue, work with the manufacturer on your behalf, and arrange for a repair or replacement with minimal hassle to you. Our goal is to make sure your security system is always functioning exactly as it should.
