Remove Dogging Hex Key: A Practical Guide to Safely and Efficiently Remove Dogging

Mechanisms

remove dogging hex key is a phrase that might sound technical or even a bit daunting

if you’re not familiar with door hardware or maintenance work. Yet, it’s a common task,

especially for anyone dealing with commercial doors, fire exits, or security systems.

Dogging mechanisms often use a hex key (Allen wrench) to engage or disengage the latch

hold-back, allowing doors to remain open or closed as needed. Understanding how to

remove a dogging hex key effectively can save you time, prevent damage, and ensure

safety. In this article, we’ll dive deep into the process, tools involved, and tips to make

your task smoother.

Understanding Dogging Mechanisms and Their Hex Keys

Before we get into how to remove dogging hex keys, it’s important to understand what

dogging is and why it matters. Dogging is a feature commonly found in panic bars or exit

devices on doors. When engaged, the dogging mechanism holds the latch in the retracted

position, keeping the door open without the need to keep pushing it. This is especially

useful in busy environments like schools, hospitals, or shopping centers where doors need

to stay open temporarily.

The dogging system is usually controlled by a hex key—a small, L-shaped tool that fits

into a specific hexagonal hole on the exit device. Turning this key locks or unlocks the

dogging mechanism. Removing or disengaging the dogging hex key means you’re

effectively controlling whether the door stays latched or held open.

Why You Might Need to Remove a Dogging Hex Key

Several scenarios call for removing the dogging hex key:

**Routine Maintenance:** To inspect or repair the door’s exit hardware.

**Security Reasons:** To prevent doors from being held open unintentionally.

**Regulatory Compliance:** Fire safety codes often require doors to close

automatically unless held open by an authorized mechanism.

**Replacing or Upgrading Hardware:** When installing new exit devices or

upgrading existing ones.

Knowing how to remove the dogging hex key properly ensures that you don’t compromise

the door’s operation or safety features.

Tools and Preparations for Removing Dogging Hex Key

Essential Tools to Have on Hand

Removing a dogging hex key might sound straightforward, but having the right tools can

make the process easy and prevent damage to the door hardware:

**Hex Key Set (Allen Wrenches):** Having a set with multiple sizes helps you find

the perfect fit for the dogging mechanism.

**Screwdriver:** Sometimes, you may need to remove cover plates or access panels

before reaching the dogging mechanism.

**Lubricant Spray:** A little WD-40 or silicone spray can loosen any rusted or stuck

parts.

**Pliers:** Useful if the hex key or dogging mechanism is stuck or needs extra grip.

Safety Precautions

Safety should never be overlooked. Since dogging mechanisms are often part of

emergency exit devices, improper handling can affect door functionality.

Make sure the door is supported and won’t swing unexpectedly when you

manipulate the hardware.

If working on fire exit doors, confirm you have the necessary permissions and

knowledge of local fire safety regulations.

Wear safety gloves to protect your hands from sharp edges or pinching points.

Step-by-Step Process to Remove Dogging Hex Key

Step 1: Identify the Dogging Mechanism

Locate the dogging hole, usually near the panic bar or exit device. It’s a hexagonal recess

designed for the hex key to fit snugly. Sometimes, there’s a cover or plate that needs to

be removed first using a screwdriver.

Step 2: Insert the Correct Hex Key

Select the hex key that fits perfectly into the dogging hole. Using too small or too large a

key can strip the edges, making removal difficult. Insert the key firmly but gently.

Step 3: Turn the Hex Key to Disengage Dogging

Typically, turning the hex key clockwise or counterclockwise will release the dogging

mechanism. The exact direction may vary depending on the door hardware brand, so

consult the manufacturer’s instructions if available.

Step 4: Remove the Hex Key

Once the dogging is disengaged, carefully pull out the hex key. If it feels stuck, avoid

forcing it; instead, try a slight wiggle or apply some lubricant and wait a few minutes.

Step 5: Test the Door

After removing the dogging hex key, operate the door to ensure the latch works correctly

and the door closes and locks as expected. This test confirms that the dogging

mechanism is fully disengaged.

Troubleshooting Common Issues When Removing Dogging Hex

Key

Sometimes, things don’t go as smoothly as planned. Here are some common challenges

and how to handle them:

Hex Key Won’t Fit or Turns Slippery

This usually means the hex key size is incorrect or the dogging hole is worn out. Try a

different size key or inspect for damage. If the hole is stripped, you may need to replace

the exit device or consult a locksmith.

Dogging Mechanism Stuck or Rusted

Older doors or those exposed to moisture might have rusted dogging parts. Apply

penetrating oil and allow it to soak in before attempting removal again. Gently tapping the

mechanism with a rubber mallet can also help loosen it.
