Fleet key management: vehicles you own vs. vehicles in your care

Most “fleet key management” buying advice collapses two problems that have opposite shapes. On a vehicle you own, you already hold every permission — the work is granting access to rotating drivers and taking it back cleanly. On a customer's vehicle, you hold none of them, and the work is documenting a visit you were never the owner of.

GuestLot is built for the second problem. If you are buying for the first, this page is mostly here to point you somewhere better — and to mark the one place the two overlap.

LAST REVIEWED SEPTEMBER 20, 2026

The authorization runs in opposite directions

This is the distinction that decides which category of product you need. Everything else — cabinets, dashboards, per-vehicle pricing — follows from it.

Owned fleet vehicle vs. customer vehicle in your care
Who grants access
A vehicle you own
You do. You hold the Tesla account and pair keys directly
A customer's car in your care
The owner does, per visit, through Tesla's own third-party app screen
How access ends
A vehicle you own
You remove the key or unpair it yourself, whenever you choose
A customer's car in your care
Visit expiry blocks new commands — it does not remove Tesla keys
Who the record is for
A vehicle you own
Your own operations, payroll, and insurer
A customer's car in your care
The owner, and only if the shop chooses to share the report
What a lost NFC card costs
A vehicle you own
A card you own, re-paired at your convenience
A customer's car in your care
A customer's card with no usage trail and no remote wipe

Where GuestLot is not the right tool

Said plainly, because a buyer comparing categories is better served by a clear no than by a page that stretches to say yes.

Continuous fleet telematics — utilization, charge state, driver scoring, dashboards across vehicles you own. That is a fleet platform's job, and Standard Fleet is one of the products built for it. See how the two differ.
Physical key enforcement. GuestLot records staff-entered handoffs; it does not lock a cabinet or force a checkout. KeyTrak, Traka, and Morse Watchmans sell hardware that does.
Per-vehicle licensing for a large owned fleet. GuestLot is one SKU at $179 per location per month. That prices for a shop with bays, not a fleet with vehicles — above a certain vehicle count a per-vehicle fleet product is simply the better buy.
Standing driver authorization across weeks. GuestLot's consent model is scoped to a single visit with a defined end, which is the wrong shape for a driver who has the car every Tuesday.
One fleet vehicle, in someone else's hands, for a defined window. That is the custody event below — and it is the same product whether the car belongs to your fleet or to a walk-in customer.

The overlap: when a fleet vehicle goes into a shop

A fleet that runs Teslas still sends them out for tint, paint protection, wrap, collision work, and warranty service. For the duration of that visit your own vehicle is in exactly the position a customer's car is in — off your lot, driven by people not on your payroll, with a key you handed over.

That is the moment worth documenting, and it is the moment most fleet software ignores, because a fleet platform is built to watch vehicles you control rather than vehicles you have temporarily given away. A condition record at drop-off and pickup, a named handoff with a timestamp, and — where the shop is running GuestLot — an owner report you receive as the owner, are the artifacts that settle a dispute about a mark that appeared during the visit.

If you are the fleet and the shop is not running anything, the handoff check is a free printable worksheet covering the same seven moments, with no signup.

What to ask a shop before handing over a fleet Tesla

Four questions, in the order they matter. Each one has a verifiable answer, and a shop that cannot answer them is telling you something.

Pre-handoff questions for a fleet vehicle
What will you record at intake?
Why it decides anything
A dispute a month later is settled by what was captured on the day, or not at all
A good answer sounds like
Timestamped condition photos, named staff, and the odometer as read at drop-off
What access do you need, and for how long?
Why it decides anything
An open-ended key handover has no defined end, so nothing marks the moment it should have stopped
A good answer sounds like
A named scope with a stated end, and a reason for each thing requested
Can you retrieve this visit in a month?
Why it decides anything
Plenty of shops record something and can never find it again
A good answer sounds like
Yes — the record stays retrievable after the car has been handed back
What happens to our keys at pickup?
Why it decides anything
This is the step that actually gets skipped, and an NFC card carries no usage trail to catch it
A good answer sounds like
Cards counted back, and any paired phone key removed in the car's own key menu

Does GuestLot manage keys for a fleet we own?

No. GuestLot is not a fleet key system and does not enforce key checkout. On a vehicle your business owns, you hold the Tesla account: pairing a phone key, removing one, and auditing who is on the car are done in the vehicle and in your own Tesla account, not through us. A fleet platform or an electronic key cabinet is the right purchase for that job. GuestLot covers a narrower moment — the visit where one of your vehicles is in someone else's hands.

Can we revoke a driver's access to a fleet Tesla through GuestLot?

No. Expiring a GuestLot visit blocks new commands from GuestLot; it does not remove Tesla keys, and it does not stop a drive already under way. A paired phone key or an NFC card stays on the vehicle until someone removes it in the car's own key menu. Treat visit expiry as the end of our authorization, never as proof that a driver can no longer open the vehicle.

One of our fleet cars is going to a tint shop. What is worth recording?

The same things that matter for any customer vehicle, except here you are the customer. Condition at drop-off and at pickup, who handed the car over and when, and — if you authorize it through Tesla's third-party app screen — available vehicle readings including the last reported location with the time it was observed. Ask the shop what it can produce a month later if you dispute a scratch. A shop that can retrieve a timestamped record is a different counterparty from one that cannot.
