Answers

Twenty-one questions people actually ask before, during, and after leaving a Tesla at a shop. Every answer is on this page — nothing is hidden behind an accordion, a form, or a sales call.

Where the answer is uncomfortable for us, it still gets answered. GuestLot is awareness software, not a security system, and it cannot stop anyone from driving a car.

For Tesla owners

Can a shop drive my Tesla without permission?

Physically, yes — anything that can unlock and start the car can drive it, and a key card left at the counter grants exactly that with no expiry and no notification. Legally it is a different matter: a shop holds your car as a bailee and owes a duty of reasonable care, and driving it beyond what the job requires is outside that duty. What you actually control is whether the trip leaves a record.

See key cards at the shop.

What happens to my key card at the shop?

It goes in a drawer, on a hook, or in a technician's pocket, and it keeps full drive access until you delete it from the car's Locks screen. Tesla vehicles hold up to 19 keys, so a card left behind in March is still valid in November. Ask for the card back at pickup and remove it from the key list while you are standing at the car.

Can a Tesla key card be remotely wiped?

No. There is no remote wipe for an NFC key card. Keys are added and removed only from the vehicle's touchscreen under Controls > Locks, using the trash icon next to the key. Any product claiming otherwise is describing something Tesla does not offer.

Can a shop see where my Tesla is?

Only if you granted the vehicle_location scope through Tesla's own authorization screen, and only for as long as that grant is live. Without it, no location-based feature works at all. With it, a responsible shop product should be reporting on-lot versus off-lot and after-hours movement — not showing staff a live map of your car.

GuestLot’s lot watch reports counts and timestamps only. That constraint is listed on the limits page.

Does Valet Mode block Service Mode?

They are separate systems and neither one is a substitute for the other. Valet Mode caps speed at 70 mph, limits power, locks the frunk and glovebox, and hides your profiles and key list. Service Mode is a technician state entered on the touchscreen or over a cable — no app can set it, because Tesla's Fleet API has no command for it.

Full breakdown: Valet Mode vs Service Mode.

Should I leave Sentry Mode on at a body shop?

Usually not for a long stay. Sentry Mode sounds a loud alarm when triggered, which is a genuine complaint from crews working around parked cars, and it draws roughly 250 to 300 watts — about a mile of range per hour. It also auto-disables around 20% state of charge, so on a multi-week job the protection you think you have quietly ends.

Will my battery drain while my car sits at a shop?

Yes, slowly, and on long collision jobs it is a real problem rather than a theoretical one — owner forums carry threads about cars sitting at body shops for months with both the high-voltage pack and the 12V battery dead. Ask the shop what its charging plan is before a multi-week stay, and whether anyone will be notified if the state of charge falls.

How do I revoke a shop's access to my Tesla?

Two paths, either one works. Open your Tesla Account and go to Security > Third-Party Apps, then revoke the app; or open the car's Locks screen and delete the app's virtual key. Revoking a scope also automatically removes any telemetry configuration that depended on it, and you never need the shop's permission to do it.

Step by step: give a shop access to your Tesla — and take it back.

For shops

Can a shop use GuestLot without the owner's phone?

Yes, but with less in the record. Check-in, the job policy, key custody, and the hand-back all work from the counter. Telemetry does not, because Tesla requires the owner to authorize through their own account and add a virtual key to the car — a shop can never connect a customer's Tesla unilaterally.

What if the owner declines to authorize?

The visit proceeds as a paper-grade custody record and the receipt says so. GuestLot prints 'not recorded' rather than implying a watch it did not have. Roughly speaking, you keep the intake, the custodian trail, and the hand-back; you lose the odometer delta, the lot watch, and the movement timeline.

Is GuestLot a security system?

No. It is awareness software, not a security SLA. It cannot immobilize a car, it cannot prevent a technician from driving one, and it does not replace cameras, fencing, or your alarm contract. What it does is make the visit legible after the fact and end access at pickup.

The whole list of things it will not do: limits we will not hide.

Can GuestLot stop a technician from joyriding a customer car?

No software can. What changes is that the trip is no longer invisible: an after-hours lot exit and an odometer delta land in the visit record, and the owner receives the same record at pickup. In the widely reported joyride cases, the evidence came from the vehicle or the owner — this simply puts a copy on the shop's side too.

The case pattern: a customer car was damaged at your shop.

Who is liable if a customer car is damaged at my shop?

A shop holding a customer's vehicle is a bailee with a duty of reasonable care. Once the customer shows the car was delivered undamaged and returned damaged, most US jurisdictions apply a presumption of negligence and the shop carries the burden of proving it exercised reasonable care. This is general information, not legal or insurance advice.

What evidence does my insurer want?

Timestamped intake condition evidence from before the work started, an odometer reading at drop-off, a named custodian for the key, and a movement record for the visit. Broker guidance is explicit that thorough intake documentation helps establish what damage was pre-existing, which is critical when coverage depends on negligence.

Do I need garage keepers coverage?

If you hold customers' vehicles, general liability alone does not cover them — garage keepers is the line that responds to damage to cars in your care, custody, and control. Which form you carry decides when it pays: Legal Liability only on negligence, Direct Primary regardless of fault, Direct Excess after the owner's own policy. This is general information, not legal or insurance advice.

Forms, limits, and exclusions: garage keepers liability.

What is pre-authorization, or hands-free arrival?

The owner authorizes before the appointment instead of at your counter. The access stays dormant, activates when the car reaches the shop, and auto-revokes at pickup. It removes the most awkward two minutes of the intake, where a service writer asks a stranger to log into their Tesla account in the lobby.

Billing and setup

How long does setup take?

A location is live the same day, and a single check-in takes about two minutes: VIN, owner mobile number, expected pickup time. There is no hardware to install, no cabinet to mount, and nothing to wire into your DMS before you can run the first car.

What does GuestLot cost?

$179 per month for Standard and $349 per month for Pro, per location, flat. There is no per-vehicle charge, so a slow February and a full December cost the same. Pro adds the Service Mode checklist and BenchNote, which decodes the VIN and pulls NHTSA recall data at intake.

Do vehicle owners need an account?

No, and by design they never will. Owners authorize through Tesla's own screen, not through a GuestLot login, and the report they receive at pickup is a tokenized link rather than a portal. Nobody should have to create an account with a vendor they have never heard of to find out what happened to their own car.

What is on the AccessReceipt?

The vehicle and a partial VIN, when access started and when it was revoked, miles driven during the visit, after-hours lot exit count, Supercharger session count, and the closing timestamp. Anything that was not recorded says 'not recorded' rather than showing a zero, because a zero and a blank are different claims.

Does GuestLot sell vehicle data?

Never. We collect only what the custody job requires, we do not sell or share vehicle data with data brokers or consumer reporting agencies, and the consent window ends at pickup. Connected-car enforcement over the last two years has been aimed squarely at companies that did the opposite.
