What to Ask Before Hiring a Kill-Switch Installer
You are handing someone your keys and letting them work inside your vehicle's electrical system. Eight questions, asked before you book, tell you almost everything about whether that is a good idea.
None of these are trick questions. A competent installer answers all eight without hesitating — and the hesitation itself is the information.

Which approach will you use on my vehicle, and why that one?
There is more than one way to immobilize a vehicle, and they carry different risk profiles. A starter-control installation cannot stall a running engine. Other approaches can. Which one is appropriate depends on your specific vehicle.
A specific approach named for your vehicle, with a reason attached to that platform — not a generic description of what they always do.
Worrying answer: "It's a kill switch, they all work the same." They do not. See our guide to the safety differences.
Do you have wiring documentation for my exact platform?
Modern vehicles run multiple networked systems, and platforms differ meaningfully even within the same manufacturer and model year. Working from a generic diagram or a "close enough" model is how expensive faults happen.
Yes, and here is what we use — or an honest "let me confirm I can source it for your vehicle before we book anything."
Worrying answer: "We've done plenty of these, we know where everything is." Experience is not documentation.
What happens if it engages while I'm driving?
This is the safety question, and you are entitled to a clear answer before anyone touches the car. Depending on the installation, an engine that stops mid-drive means losing power steering assist and brake booster assist at the same moment.
A plain description of exactly what your vehicle would do, plus an unprompted instruction never to activate it while the vehicle is moving.
Worrying answer: anything vague, or an enthusiastic pitch about shutting a thief down remotely while they drive. That is a liability, not a feature.
Do you publish or demonstrate where you hide things?
A slightly odd question, and a revealing one. Concealment only works while it is confidential. Installers who show placements in videos or name them publicly have devalued that concealment for every customer they have.
No — and a brief explanation of why not. You should be told a system is installed and how to operate it, not shown the spot on camera.
Worrying answer: a link to their install videos. See why concealment depends on staying quiet.
Will you document my vehicle's condition before you start?
This protects both sides equally. Without a pre-work record, any pre-existing mark becomes a dispute, and any damage genuinely caused during the work becomes deniable. A written and photographed baseline removes the argument entirely.
Yes, photographed and recorded before anything is touched, and you get a copy.
Worrying answer: "We're careful, it won't be an issue." Careful people still document.
What exactly is warrantied, and for how long?
There are two different things here and they are frequently blurred. The hardware is covered by the manufacturer's terms. The installation workmanship is covered by the installer, or it is not covered at all.
A stated workmanship warranty with a defined period, in writing, and a clear separation from the manufacturer's hardware coverage.
Worrying answer: "It's all warrantied" with no distinction and nothing written down.
What do you not work on?
Possibly the most useful question on this list. Every competent shop has limits — EV high-voltage systems, airbag and SRS circuits, driver-assist calibration, platforms they cannot source documentation for.
A specific list, given without defensiveness, ideally with an offer to refer you elsewhere for that work.
Worrying answer: "We can do anything." Nobody can do anything. That answer means they have not thought about where their limits are, or they are not telling you.
What is the total cost, including anything recurring?
Tracking systems generally require a subscription for live location and remote commands. That is normal — but it should be disclosed upfront rather than discovered after the install.
The installed price, plus the recurring cost stated separately with who bills it, before you commit to anything.
Worrying answer: a single number with no mention of ongoing cost. Ask directly if it does not come up.
Beyond the answers
Four Things Worth Noticing
Signals that show up independently of what anyone says on the phone.
They quote before they ask
A price given without knowing your year, model, trim or prior electrical work is not a quote for your vehicle. It is a number.
Nothing is in writing
A verbal warranty is not a warranty. Scope, price and coverage should exist on paper before work starts.
They oversell the outcome
No system guarantees a vehicle is not stolen. Anyone promising that is either unfamiliar with the subject or comfortable overstating it.
Questions seem to annoy them
You are asking about work inside your own vehicle. Irritation at reasonable questions tells you how a real problem would go.
In fairness
Plenty of Good Installers Exist
This is not an argument that everyone else is careless. There are excellent installers in Metro Detroit and everywhere else, and some of them are very small operations doing genuinely meticulous work.
The point is that you can tell the difference in one phone call. The good ones answer these questions easily, because they have already thought about all of it. If another shop gives you better answers than we do, use them — you will end up with a better result, which is the actual goal.
One question that is not on the list
"How cheap can you do it?" A kill switch is wired into the system that starts your vehicle. The gap between a careful installation and a rushed one is not visible at handoff — it surfaces months later as a fault, a drain, or a no-start in a parking garage.
Price matters. It should not be the first question, and it should never be the only one.

- Do you publish locations?The answer should be no.
- Condition documented first?Photographed, with a copy.
- What's warrantied, how long?Workmanship vs hardware.
- What don't you work on?Everyone has limits.
- Total cost, including recurring?Subscription disclosed.
Common questions
Hiring Questions
What owners ask when choosing an installer.
Is it rude to ask all of this?
No. It is work inside your vehicle's electrical system, and any installer worth hiring expects these questions and answers them comfortably. If asking feels awkward, that discomfort is worth paying attention to.
Should I get multiple quotes?
Getting a couple of opinions is reasonable, particularly on an unusual vehicle. Compare the answers to these questions rather than just the numbers — the cheapest quote and the best-informed one are frequently not the same call.
What if I already had one installed badly?
Bring any documentation you have from the previous installer. Knowing what was done, and where, saves diagnostic time and reduces cost. Previous work is common and is not a reason to avoid getting it looked at.
Does a bigger shop mean a better install?
Not necessarily. Some of the most careful work comes from small operations, and some large shops rotate this work through whoever is available. Judge the answers, not the size of the building.
How do I know the work was done properly afterwards?
The vehicle should behave exactly as it did before — no warning lights, no battery drain, no visible evidence of the work. You should have your condition documentation, a written warranty, and a clear understanding of how to operate the system.
What should I be told at handover?
How the system operates, the conditions under which it should and should not be used, how to use the app, what the warranty covers and for how long, and who to contact if something seems off.
