Unlocking a commercial door may seem straightforward, but with the wide variety of commercial locks and security features today, the process can be more complex than most people expect. Whether you’re facing a jammed lock, a lost key, or a malfunctioning access system, knowing how to unlock commercial door hardware is an essential skill for any business owner or facility manager. This guide will walk you through the most common types of commercial door locks, practical unlocking methods, troubleshooting tips, and when to call in a professional.
Understanding Commercial Door Locks
Before you learn how to unlock commercial door systems, it’s important to understand the types of locks you may encounter. Commercial doors often use more robust and secure lock mechanisms than residential doors. Here’s a table summarizing some of the most common types:
| Lock Type | Description & Use Case | Unlocking Method |
|---|---|---|
| Mortise Lock | Heavy-duty, found in offices and storefronts | Key, sometimes thumb-turn |
| Cylindrical Lock | Common in offices, easy to install | Key or push/turn button |
| Electric Strike | Used with access control, releases with electric signal | Keypad, card, fob, or manual override |
| Magnetic Lock | Uses electromagnet, often with access control | Keypad, card, fob, or power cut |
| Panic Bar/Push Bar | For emergency exits, allows fast egress | Push bar from inside, dogging key |
| Keypad/Keyless | PIN, card, or biometric access | Code, card, fob, or backup key |
Knowing your lock type is the first step in understanding how to unlock commercial door hardware safely and efficiently.
Common Reasons Commercial Doors Won’t Unlock
If you find yourself unable to open a commercial door, the cause is often one of the following:
- Lost or misplaced keys
- Dead batteries (for electronic or keypad locks)
- Jammed or misaligned latch
- Power failure (for electric or magnetic locks)
- Broken or worn-out lock components
- Panic bar or crash bar stuck in the locked position
Identifying the issue will help you choose the right method for how to unlock commercial door systems.
Step-by-Step: How To Unlock Commercial Door
1. Use the Correct Key or Access Method
Most commercial doors are designed to be secure, so using the correct key, card, fob, or PIN code is always the first step. For keyless systems, double-check that you are entering the correct code or using a programmed card/fob.
2. Unlocking a Panic Bar or Push Bar
If your commercial door has a panic bar (also called a crash bar), look for a small hole or slot on the bar or its ends. Many panic bars can be “dogged” open using a dogging key, which is often just a hex or Allen wrench. Insert the tool and turn to release or secure the latch. This is a common method for how to unlock commercial door exit devices.
3. Manual Override for Electric or Magnetic Locks
For electric strikes or magnetic locks, there is usually a manual override key. If the power is out, these locks may default to an unlocked or locked position depending on their configuration. Always check if there’s a backup key or override switch.
4. Try Non-Destructive Entry Methods
If you’re locked out and don’t have the key, you may attempt non-destructive methods such as:
- Credit card method: Works only on simple spring latch locks, not deadbolts or high-security locks. Slide a flexible card between the door and frame above the latch, then wiggle and push to retract the latch.
- Paperclip or hairpin: For simple privacy locks, insert a straightened paperclip into the small hole on the knob and push until the lock disengages.
- Lock picking: Requires skill and special tools; not recommended unless you have experience.
5. Last Resort: Drilling the Lock
If all else fails and immediate access is necessary, drilling the lock may be an option. This will destroy the lock and require replacement, so it should only be used as a last resort and ideally by a professional locksmith.
6. Check for Alignment or Jam Issues
Sometimes, a commercial door won’t unlock because it’s misaligned or the latch is jammed. Inspect the door for visible misalignment or obstructions. Gently push or pull the door while turning the key or handle to see if it opens.
Troubleshooting Tips for Unlocking Commercial Doors
If you encounter issues with unlocking a commercial door, start by testing another key or fob to eliminate the possibility of a faulty credential. For electronic locks, check and replace the batteries if they’re low or dead. If a panic bar is stuck, inspect the mechanism for debris or damage that might be obstructing its movement.
Doors that stick or jam often have misaligned hinges or frames, so re-leveling the door may resolve the issue. Always avoid forcing the lock, as excessive pressure can damage internal components and lead to costly repairs.
Preventing Future Lockouts
To minimize the risk of lockouts, maintain spare keys or access credentials in a secure but accessible location. Regularly lubricate locks and door hardware to ensure smooth operation and reduce wear. Train employees on proper usage of panic bars, keypads, and access systems to prevent accidental lockouts.
Schedule routine inspections for both electronic and mechanical locks to catch potential issues early. For reliable long-term solutions, partner with a professional service like Doorway Dynamics to ensure your commercial doors remain secure and functional.
