Should an escape room business buy new or used equipment
Escape room owners should weigh new versus used equipment by considering how often each prop runs and what a mid-game failure costs their business.
What to take away
- Buy new equipment for the escape room that earns the most; the lobby and back office can absorb a used purchase.
- Magnetic locks, prop electronics and controllers fail differently, and each failure costs a different amount of lost bookings.
- Ask for the maintenance log, the model number and the spare parts list before you buy anything used.
- Budget the install, not just the unitpower, data, mounting and reset time all land on the invoice.
- A new SECO-LARM E-941SA-600Q magnetic lock lists around $130; the same model typically sells used for $40 to $70.
- Confirm accessibility and egress duties with the local fire marshal and a licensed architect or engineer.
This article covers operating decisions, not code compliance. Egress, occupancy, accessibility and electrical requirements vary by building and jurisdiction. Confirm current duties with your local fire marshal, the state or provincial licensing authority, and a licensed architect or engineer.
The room that earns the most sets the standard
Sort your rooms by revenue per available slot, not by how new they look. The highest-earning room is the one a failure hurts most, so that is where new equipment pays for itself.

A dead magnetic lock on a Saturday is not a repair bill. It is a refunded booking, a bad review and a game master standing in a dark corridor. Price the failure before you price the unit.
The lobby, the briefing room and the staff office can run on used gear almost indefinitely. A $40 used Dell monitor from Facebook Marketplace or a refurbished iPad on the waiver desk does not cancel anyone's birthday.
What breaks, and how often
Magnetic locks and their power supplies are the most common failure point. They cycle hundreds of times a week and heat is what kills them.
A new SECO-LARM E-941SA-600Q rated at 600 pounds of holding force typically runs $100 to $160, and a DynaLock 3001 sits near the top of that range. Used units on eBay or Facebook Marketplace usually sell for $30 to $70, and a failing coil rarely shows in a photo.
Prop electronics, reed switches and relays come next. A sensor that reads a drawer as closed when it is open will strand a team until a hint arrives.
An Arduino Uno board lists around $28, and a reed switch from Adafruit costs about $1.50. The hardware is cheap. Tracing a bad solder joint between shows is not.
Controllers and show-control software fail least often but cost the most downtime. A controller that will not boot takes the whole room offline, not one puzzle.
An EFX-TEK Prop-1 board runs about $100, and an AutomationDirect CLICK PLC costs $100 to $250. Show control on a Mac usually means QLab, with licences in the low hundreds per seat. A used controller with locked firmware or no vendor support is a paperweight.
Mechanical props wear predictably. A crank, a hinge or a sliding panel gives warning before it dies, which makes them the safest used purchase in the building.

The arithmetic before you decide
Write the numbers down rather than arguing about them. A used unit is worth buying when its purchase price plus expected repairs over the term stays below the new price, and when the downtime it causes costs less than the difference.
Three-year cost: used vs new lock
Option
- Used $60 lock
- $585 with repairs and lost slot
- New $140 lock
- $140 with two-year warranty
- Electrician time
- $75 to $150 an hour, half-day minimum
Three-year cost
- Used $60 lock
- New $140 lock
- Electrician time
Put it in variables you can fill in: purchase price, expected repairs per year, hours of lost bookings per failure, revenue per hour, and the resale value at the end of the term. If the used unit loses two prime Saturday slots a year, that alone can erase the saving.
One worked example: a $60 used lock that needs a $75 repair each year and one $180 lost slot over three years costs $585. A new $140 lock with a two-year warranty costs $140. Electrician time, typically $75 to $150 an hour with a half-day minimum per lock, lands on both sides of the comparison.
Ask the seller for the maintenance log, the exact model number and the spare parts list. If any of the three is missing, treat the price as if the unit will fail in month one.
Where the authorities come in
Accessibility duties for an existing venue sit with the ADA guide for small businesses, which covers barrier removal, accessible routes and what is readily achievable. Read it before you buy anything that changes a route or a doorway.
A safety program that finds hazards before an inspection does is the frame OSHA sets out in its safety management guidance. Used gear with a missing guard or a frayed cable belongs in that program, not in a room.
Emergency planning, including evacuation, accountability and staff training, is covered in OSHA's emergency preparedness guidance. Any equipment that affects how a team leaves the room has to fit that plan.
Fit the purchase to the plan
The equipment list in your escape room business plan should say which items are revenue-critical and which are not. That split decides where new money goes.
Before you compare suppliers
- Mark which items are revenue-critical
- Split new money toward revenue-critical gear
- Walk the equipment and setup guide
- Build a room-by-room buy list
- Sequence purchases across seasons
If you are still specifying rooms, the equipment and setup guide walks through what a build needs before you start comparing suppliers. FrightProps and Escape Room Supplier both sell new prop controllers, sensors and locks.
For a room-by-room buy list with quantities and sequencing, use the equipment checklist for new owners. It is the fastest way to see which purchases can wait a season.
Common questions
Is used escape room equipment ever the right call?
Yes, for spares, for the lobby and for low-traffic rooms. A $40 used SECO-LARM lock on the shelf as a spare is sensible. The test is whether a failure there costs a booking. If it does, buy new.
What should I ask a seller before buying used gear?
Ask for the maintenance log, the model number and the spare parts list. A seller who cannot produce all three on eBay or Facebook Marketplace is selling you an unknown repair bill.
How do I compare a cheap used unit with a new one?
Convert both to cost per year of service, including expected repairs and lost bookings. A $60 used lock that eats one $180 Saturday slot has already cost more than a $140 new one.
Does buying used change my safety duties?
No. The duties follow the equipment in use, not its age. Confirm with your fire marshal and a licensed architect or engineer.
