Lunar Key Access: A Small Elevator Upgrade That Can Make a Life-Saving Difference

Fast emergency access matters, here’s how to make it happen.

 

 

A 4 A.M. Elevator Stall—Now What?

It’s the middle of the night. A brief power fluctuation stalls an older elevator between floors. Four passengers are trapped inside, growing anxious. Firefighters arrive, but there’s a problem: the landing doors have no lunar-key access holes. Without those, the only way to open the door is from the inside the elevator, or from the machine room above.

Your elevator mechanic races to the top floor, diagnoses the fault, and manually runs the elevator to a landing. What should take minutes can stretch to an hour, time that could turn a minor inconvenience into a medical emergency.

 

 

What Is a Lunar Key?

A lunar key (also called a drop key) is a small, L-shaped tool that fits into a designated round hole in the top corner of an elevator landing door. When inserted, it mechanically releases the door lock. This allows a qualified person, such as a firefighter or licensed elevator mechanic, to open the door safely from the hallway, even if the car is near but not exactly at the floor.

 

 

Why Your Building Should Retrofit Lunar-Key Holes

Benefit	Impact
Rapid passenger extraction	Doors can be opened in under 2 minutes, even if the car is inches away
Reduced burden on first responders	No more forced door entries or long waits for machine room access
Increased passenger safety	Faster rescue lowers the risk of medical complications or panic attacks
Code alignment	CSA B44 now requires unlocking devices, retrofitting supports compliance

 

How the Retrofit Works

1. Site Inspection
   A technician checks door type and confirms safe retrofit locations
2. Precision Drilling
   A ½-inch hole is drilled at the approved point, no full door removal needed
3. Install Bushing & Label
   A protective metal sleeve reinforces the access hole, and a glow-in-the-dark label is added
4. Function Test
   The technician verifies proper unlocking and secures the door’s interlock

Most buildings can be fully retrofitted in one business day, with minimal tenant disruption.

 

 

Peace of Mind at a Modest Cost

Compared to the liability of a delayed rescue, or the emotional toll on trapped passengers, lunar-key access is a low-cost, high-impact upgrade. It’s a one-time investment in emergency readiness that pays for itself the first time it’s needed.
