Onboarding and offboarding
Give a new hire access on day one and shut off a departing employee's credential immediately, without rekeying a single lock.
● Commercial security
Control who gets into your building, which doors they can open and when, with cards, fobs or phones instead of keys you can't track. Planned, installed and supported by a local team in Nashville and Chattanooga.

Commercial access control is an electronic system that decides who can unlock each door in your building and at what times. Instead of handing out keys, each person gets a card, fob or phone credential. You can add, change or remove a person in minutes, and the system keeps a record of every entry.
Turner Security designs access control around your doors, your people and your schedule, then installs and supports it from our offices in Smyrna and Chattanooga.
Every system starts with a walkthrough of your doors, gates and daily routine. These are the parts we plan and install.
Give a new hire access on day one and shut off a departing employee's credential immediately, without rekeying a single lock.
Choose key cards, fobs, PIN codes or phone-based credentials, or mix them across user groups like staff, vendors and tenants.
Secure main entrances, side doors, server rooms, stock rooms and vehicle gates, each with its own rules about who can enter.
Unlock doors automatically during business hours, lock them after hours, and look up who opened which door and when.
Manage several buildings or offices from one dashboard, with the same standards and permissions at every site.
Tie door events to camera footage and your alarm system, so a forced door or after-hours entry is easy to review.
Keys get copied, lost and never returned. When someone leaves, you often can't be sure who still has access. Access control fixes that by tying every door to a person, a credential and a schedule.
It also gives you a record. If something goes missing, you can see who was in the building and pair that with camera footage instead of guessing.

A clear process with one team from start to finish.
We look at every door, gate and user group and ask how your day actually runs.
You get a plan for readers, locks, credentials and software, with a clear price.
Our crews install and test each door, then set up your users and schedules.
We show your team how to manage it and stay available for service.
Cost depends mostly on the number of doors, the type of locks and readers, and whether you want cloud management. We give you a free assessment and a written proposal with a clear price before any work starts.
Yes. The systems we install let you add or remove people, change schedules, unlock a door remotely and check entry history from a phone or computer.
In most cases, yes. We review your current doors, frames and hardware and tell you which can be fitted with electronic locks or strikes and which may need new hardware.
Yes. We can connect door events to your camera system so you can quickly pull up video of who entered a door at a specific time.
Yes. Multi-site businesses and property managers can run several buildings from one dashboard with consistent rules at each site.
Systems are planned with battery backup power supplies, and each door is set to fail safe or fail secure based on fire code and how that door needs to behave.

I spoke with a gentleman named TJ today. In spite of me not having all the information available to properly communicate and identify the issue, he patiently walked me through steps to identify and troubleshoot one of our doors we were having issues with. The issue ended up not having anything to do with a Turner Security device but through process of elimination, he helped me find a solution to the issue. TJ was genuinely patient, friendly, and professional and I feel like he went above and beyond to help me resolve the issue.
I received excellent customer service and help with our access control system from Tommy Oliver. He was patient and helpful from start to finish!
