The short answer: Some manufacturers build elevators with proprietary controllers, software, and parts that only their own service division can fully access — then write maintenance contracts that still exclude big-ticket items. That’s the double standard: they lock out competitors but don’t fully back the equipment either. Find out whether your equipment locks you in, and what independent options exist, before you’re stuck.
The double standard, plainly
Here’s the part the industry doesn’t spell out. A manufacturer can build your elevator with proprietary controllers and diagnostic software that only its technicians can fully access — locking out every other competitor. You’d think that means the manufacturer stands fully behind the equipment it alone can service.
Often it doesn’t. The same OEM will write a “full maintenance” contract that still carves out obsolete parts, certain component failures, or major repairs — billing them on top. So you get the worst of both: you can’t shop the work to a competitor because the equipment is locked, and the manufacturer that holds that lock still won’t fully cover its own equipment in some cases. That’s the double standard.
How the lock-in actually works
Proprietary lock-in isn’t one thing — it’s a stack of them, and they reinforce each other.
- Proprietary controllers, boards and software. The elevator’s brain runs on the manufacturer’s code. Adjusting, diagnosing, or reprogramming it may require a password, a laptop, or a tool only the OEM’s technicians carry.
- Proprietary parts. Boards and components sourced only through the manufacturer, on the manufacturer’s timeline and at the manufacturer’s price.
- Diagnostic access. Even an excellent non-OEM elevator company may be able to do routine maintenance but not the deep troubleshooting the proprietary tools unlock — which quietly forces you back to the OEM for anything serious.
Each layer alone is a nuisance. Stacked, they mean that even if you’re unhappy, your realistic options are narrow — and the OEM knows it.
Why this limits your leverage
Leverage in this industry comes from your ability to walk. A competing bid is what keeps a service company honest. Proprietary equipment lock-in is designed to take that away: if only one company can fully service your equipment, “competitive bid” starts to lose its meaning, and the exclusions in the contract get harder to push back on.
This is why you are locked in to the contract and the exclusions at the same time. It’s not a coincidence — reduced competition and thin coverage travel together, because the party with the lock has little reason to offer more.
What you can still do about it
Lock-in is a spectrum, not a wall. Your equipment may be fully proprietary, partly open, or genuinely serviceable by another elevator service company — and you need to know which before you assume you’re stuck.
- Find out exactly how proprietary your equipment is. Which controller and software does it run? Can an independent get diagnostic access, or only the OEM? The answer determines every option you have.
- Read the exclusions against the proprietary equipment. If the OEM controls the parts and excludes them from coverage, that’s the specific clause to challenge or price out before you renew.
- Confirm whether another elevator service company can do the work. Some other non-OEM elevator companies can fully service equipment owners assume is OEM-only. Don’t take “it has to be us” at face value — verify it.
- Factor lock-in into every future purchase and modernization. When you replace a controller usually called a modernization, the choice you make either deepens the proprietary equipment you are locked into. Non-proprietary or open-protocol options exist; weigh them deliberately.
The industry won’t volunteer this
No manufacturer’s salesperson opens with “and by the way, this equipment locks you to us and we still won’t fully cover it.” Proprietary systems get sold on cost, space, reliability and integration — which may be real — while the leverage cost stays unspoken. Knowing whether your equipment ties your hands is the difference between choosing your service relationship and being assigned one.
What to do next
- You’re not sure whether your equipment is proprietary: ask an independent elevator consultant to identify your controller and software and tell you who can actually service it.
- You have an OEM full-maintenance contract: have it reviewed to see what’s excluded despite the “full” label, and where the lock-in clauses sit.
- You’re evaluating a modernization or new install: get the proposal reviewed so you understand whether you’re buying into more proprietary lock-in or out of it.
- You want out from under a single-vendor relationship: put your service out for a competitive bid on matched terms and find out what other elevator service options really exist.
We’re independent. We don’t work for the manufacturers, so we’ll tell you plainly whether your equipment locks you in — and what you can actually do about it.
FAQ
What does “proprietary equipment” mean on an elevator?
It means the manufacturer built the controller, software, or parts so that only its own service division can fully access them — through passwords, proprietary tools, or parts sold only by the OEM. That can limit your ability to hire another elevator service company later.
Why would a manufacturer exclude repairs on equipment only it can service?
Because lock-in and thin coverage travel together. If only the OEM can fully service the machine, it has little competitive pressure to cover more — so you can find both the exclusive access and the carve-outs in the same contract. That’s the double standard.
Can another elevator service company service proprietary elevator equipment?
Sometimes, it really depends on the equipment. The only way to know your situation is to identify your specific equipment and confirm what another elevator service company can access.
How do I know if my elevator locks me into one vendor?
Identify your equipment, and ask whether another elevator service company can get full diagnostic access or only the OEM can. Then read your contract’s exclusions. Together, those tell you how locked in you really are and if your equipment is proprietary.
Can I avoid lock-in and proprietary equipment on my next modernization?
Yes. Non-proprietary and open-protocol control options exist, and the choice you make at modernization either deepens the lock-in or breaks it. Get the proposal reviewed so you weigh that trade-off deliberately rather than by default.
