On average, replacing a commercial door lock can cost anywhere from $80 to $600, depending on the complexity of the lock and installation. Avoiding common mistakes is key to getting the job done right and saving money.
Some high-tech upgrades like smart locks can range from $250–$500, providing enhanced security but with a slightly higher initial cost.
In this guide, we’ll walk you through the necessary tools, step-by-step instructions, and expert tips to help you replace your commercial door lock without any hassle.
Tools and Materials Needed
Without the proper materials, you may run into alignment issues or even damage the door. Here’s a list of essential tools you’ll need to complete the job properly and avoid costly mistakes.
Replacement Lock
The most important item for this task is the replacement lock itself. Choose a lock that matches the specifications of your door to ensure a proper fit and optimal security. Don’t forget to double-check compatibility, particularly if you’re upgrading to a smart lock. Selecting the wrong lock can cause unnecessary complications and potential security risks.
Screwdrivers (Phillips and Flathead)
You’ll need both Phillips and flathead screwdrivers to remove the old lock and install the new one. These tools are essential for unscrewing the cover plate, mounting screws, and any other components holding the lock in place. Having both types ensures you’re prepared for any screws you may encounter.
Measuring Tape
Measuring tape ensures the lock is positioned correctly. Accurate measurements align the lock with the door’s existing holes or guide the placement for new ones. This tool helps prevent misalignment and ensures a secure fit.
Power Drill (Optional)
Using a power drill speeds up the process, especially when creating new holes for the lock. While not always required, it can make the installation more efficient, ensuring a quicker and smoother result.
Key (For Testing)
Testing the new lock with the key ensures it operates smoothly. The key verifies proper functionality, confirming that the lock engages securely and turns without issues.
Pen or Pencil
Using a pen or pencil helps mark measurements and drilling points on the door. These markings ensure the lock is positioned accurately, preventing errors and ensuring a smooth installation process.
Step-by-Step Guide
Replacing a commercial door lock requires careful steps to avoid costly mistakes. Follow this guide to ensure a smooth and secure installation.
Prepare for Removal
Before removing the lock, check the door’s alignment and make sure the hinges are secure. A misaligned door can create pressure that damages the new lock over time. Look closely at the area around the current lock for any cracks or wear. Cleaning off dust, paint, or buildup will also help make the removal smoother and safer.
Neglecting to check door alignment before removal. This can cause stress on the new lock during installation, leading to misalignment and future failures.
Remove the Existing Lock
Start by unscrewing the lock from the interior side of the door. Carefully pull apart the inside and outside handles along with any faceplates or strike components. Use a key or tool to release the lock cylinder, if needed. Keep removed parts organized, and support the door to prevent shifting while working.
Install the New Lock
Slide the latch into the edge of the door and fasten it with screws. Align the interior and exterior lock pieces, then connect them through the opening. Tighten the screws gently to avoid shifting the lock out of place.
Installation costs for smart locks, including hardware, generally range from $212 to $503, depending on the region and the specific technology features, such as WiFi or biometric access.
Once the main parts are secured, check the handle direction and make adjustments if needed. Insert the cylinder, then test the lock to ensure it functions smoothly.
Final Adjustments
Tighten every screw to hold the lock firmly in place. Adjust the strike plate so it lines up with the latch and sits flat on the door frame. Open and close the door a few times. If the latch feels rough or scrapes the edge, check for small gaps or shifts in the frame that may need fixing. Forgetting to test the lock and strike plate alignment before finishing. This simple misalignment can result in additional repair costs and premature lock damage down the road.
