Welcome to the MM Garage Door Repair Utah blog! As your trusted local garage door experts, we’re dedicated to providing you with valuable information and solutions for all your garage door needs. Today, we’re tackling a common issue for commercial property owners: replacing a commercial door lock. While it might seem straightforward, there are nuances to consider to ensure security and proper functionality. So, let’s dive in!

Understanding Commercial Door Locks

Commercial door locks differ significantly from residential locks. They’re built for higher usage, increased security, and often integrate with access control systems. They are generally more robust and complex. Before you even think about replacing the lock, it’s important to identify the type of lock you’re dealing with. Common types include:

• Cylindrical Lever Locks: These are common in office buildings and offer a good balance of security and ease of use.
• Mortise Locks: These are heavy-duty locks often found on exterior doors and require a pocket to be cut into the door.
• Exit Devices (Panic Bars): Designed for emergency egress, these are crucial for safety in commercial buildings.
• Electronic Locks: Keypad or card-based locks offering advanced access control.

Knowing the type of lock is the first step in a successful replacement.

Tools You’ll Need

Gathering the right tools before you start will save you time and frustration. Here’s a basic list:

• Screwdrivers (Phillips and flathead)
• Pliers
• Wrench (adjustable)
• Safety Glasses
• Gloves
• New Lock Cylinder or Complete Lockset
• Measuring Tape

Depending on the type of lock, you might need additional specialized tools. Always refer to the manufacturer’s instructions for your specific lock.

Step-by-Step Guide to Replacing a Commercial Door Lock

Now, let’s get to the actual replacement process. Remember, safety is paramount. If you’re uncomfortable with any of these steps, don’t hesitate to call MM Garage Door Repair Utah for professional assistance.

1. Assess the Situation: Before you start, carefully examine the existing lock. Note its type, how it’s installed, and any specific features. Take pictures for reference.
2. Remove the Old Lock: This is where the specific steps will vary depending on the lock type.
   • Cylindrical Lever Lock: Typically, you’ll find screws on the inside lever. Remove these to detach the lever and expose the cylinder. Use a key to rotate the cylinder to a specific position (usually marked) and then remove it.
   • Mortise Lock: Remove the faceplate screws on the edge of the door. Then, carefully slide the mortise lock body out of the door. You may need to loosen the lever handles and cylinder first.
   • Exit Device: These often have multiple screws and connecting rods. Carefully detach the rods and then remove the screws holding the device to the door.
3. Prepare the Door (If Necessary): Sometimes, the new lock might require minor adjustments to the door. This could involve enlarging the existing hole or drilling new ones. Use a template (often provided with the new lock) to ensure accurate placement.
4. Install the New Lock: Follow the manufacturer’s instructions carefully. This usually involves inserting the lock body into the door, attaching the levers or handles, and securing everything with screws.
5. Test the Lock: Once the lock is installed, thoroughly test it. Make sure the key works smoothly, the levers turn easily, and the lock engages and disengages properly. Check for any binding or resistance.

Tips for a Smooth Replacement

Here are a few extra tips to ensure a successful lock replacement:

• Read the Instructions: Always read the manufacturer’s instructions before you start. This will provide specific guidance for your particular lock model.
• Take Your Time: Don’t rush the process. Work carefully and methodically to avoid mistakes.
• Lubricate Moving Parts: After installation, lubricate the moving parts of the lock with a silicone-based lubricant to ensure smooth operation.
• Keep Track of Parts: Keep all screws and small parts organized to avoid losing them.

Troubleshooting Common Issues

Sometimes, things don’t go as planned. Here are a few common issues you might encounter and how to address them:

• Lock Cylinder Won’t Turn: Make sure you’re using the correct key and that the cylinder is properly aligned. Try lubricating the cylinder with a graphite lubricant.
• Door Won’t Latch: Check the alignment of the strike plate on the door frame. You may need to adjust its position.
• Levers are Stiff: Lubricate the lever mechanism with a silicone-based lubricant.

FAQs

Q: How do I know what size lock cylinder to buy?

A: Measure the length of the existing cylinder from end to end. You’ll need to match this measurement when purchasing a replacement.

Q: Can I rekey my existing lock instead of replacing it?

A: Yes, rekeying is an option. However, if the lock is old or damaged, replacement might be a better long-term solution.

Q: What if I can’t remove the old lock?

A: Don’t force it. You could damage the door or the lock mechanism. Call a professional locksmith or garage door technician for assistance.

Safety Note

Always wear safety glasses and gloves when working with tools. Disconnect any electrical power to the door if you’re working with an electronic lock. If you’re unsure about any step, consult a professional.
