Products · Remote lock & unlock
Why should keys hold you back?
Unlock any vehicle in your fleet from anywhere, with the touch of a button. RFID staff cards mean your drivers carry no keys at all. Disable a compromised vehicle remotely. It's like having a fleet keychain - only without the keys.
30 minutes, scoped to remote vehicle access on your fleet. No sales script.
Always-on, encrypted, two-way
Remote lock and unlock works because TRACKbox holds a persistent encrypted connection to the Sensium Connect cloud — commands can be sent down to the device, not just data pulled up from it. Poll-based competitor architectures physically can't do this.
Why remote vehicle access matters
Four things keys can't do.
Remote vehicle access
Send commands to the vehicle. Not just read data from it.
Anywhere, anytime control
The desk-to-vehicle distance is zero.
Picture this — you're sitting comfortably at your desk and with one tap, a vehicle across the city is unlocked and ready to go. Or you're in Brisbane and a driver in Auckland needs access. Or you're at home on a Sunday and a maintenance crew needs to retrieve a tool from a parked truck. Remote vehicle access removes the distance between fleet manager and vehicle.
Operational unlock
No more coordinating physical key handovers across sites. No more driving to a depot to unlock a vehicle for a contractor. No more lost-key replacement runs. The fleet manager has the same access from anywhere as they would standing next to the vehicle.
Access methods
Sensium Connect app
Remote from any device, any location
RFID staff card
Tap to unlock, auto-start booking
Sensium-issued fob
Where staff cards aren't available
RFID staff card integration
Keyless entry, tap-to-unlock access.
Pair TRACKbox with a keyless entry module and your drivers stop carrying keys entirely. They tap their existing staff card or an RFID fob on the vehicle's card reader — the TRACKbox unlocks the vehicle, starts the booking, and alerts the fleet manager that the driver has taken control. The vehicle remains locked to anyone without an authorised card.
Hardware kill switch
Disable a stolen vehicle, from anywhere.
The Sensium Disable Module is a hardware-based kill switch that prevents the vehicle starter from operating until you re-enable it from the dashboard. Stolen vehicle? One click from your desk and it won't start. Compromised driver? Same. The Disable Module uses an encrypted two-way connection with acknowledgement — you know the command was received and actioned, not just sent into the void.
Disable Module
Hardware-level engine disable triggered from Sensium Connect or the API. Encrypted two-way channel with acknowledgement, so you know the command landed. Re-enable from the dashboard when the vehicle is recovered.
Multi-site management
Centralised access control across every depot, every region, every vehicle. No per-site key management. Pairs naturally with Sensium Pool Vehicle Booking for cross-site shared-fleet operations.
Multi-location fleets
One control surface. Every site.
Whether your vehicles are scattered across different depots or your drivers are operating remotely, Sensium gives you complete central control. No site-by-site key cabinets to maintain. No locally-stationed staff for after-hours access. One dashboard manages every vehicle, everywhere.
See remote access against your own depots and sites - 30 minutes, no sales script.
Frequently asked
Remote lock & unlock questions.
Question 01
How does remote lock and unlock work?
Question 01
How does remote lock and unlock work?
TRACKbox holds a persistent encrypted two-way connection to the Sensium Connect cloud. Commands sent from the dashboard (or the Connect mobile app) reach the device in real time. The TRACKbox interfaces with the vehicle to lock, unlock, or disable as requested. No driver action, no phone-vehicle pairing — the channel is always open.
Question 02
What about RFID / fob / staff card access?
Question 02
What about RFID / fob / staff card access?
A keyless entry module pairs with TRACKbox to read RFID staff cards or key fobs. When a driver swipes their card, the TRACKbox unlocks the vehicle, starts the booking automatically, and alerts the fleet manager that the driver has taken control. No physical keys required for the driver, but the vehicle remains locked to anyone without an authorised card.
Question 03
Can I disable a stolen or compromised vehicle remotely?
Question 03
Can I disable a stolen or compromised vehicle remotely?
Yes. The Disable Module is a hardware-based kill switch that prevents the vehicle starter from operating until re-enabled from the dashboard. It uses an encrypted two-way connection with acknowledgement for data security and reliability. Can be triggered from Sensium Connect or via API.
Question 04
Does this work for multi-location fleets?
Question 04
Does this work for multi-location fleets?
Yes — that's actually one of the strongest use cases. Whether your vehicles are scattered across different sites or your drivers are operating remotely, you get complete central control. Unlock a vehicle in Brisbane from your desk in Auckland.
Question 05
What hardware is required?
Question 05
What hardware is required?
Remote lock and unlock requires a TRACKbox (TB2 or TB4) plus a keyless entry / actuator module wired into the vehicle. The system can be retrofitted to most modern vehicles. Talk to us about your specific fleet mix and we will scope the install.
Question 06
How secure is the connection used to lock and unlock?
Question 06
How secure is the connection used to lock and unlock?
Commands travel over an encrypted two-way connection between the TRACKbox and Sensium Connect, and the disable command uses acknowledgement so you know it was received and actioned, not just sent. Sensium Connect is hosted on Google Cloud Australian infrastructure with data encrypted in transit and at rest.
Question 07
Can drivers be issued access without giving them physical keys?
Question 07
Can drivers be issued access without giving them physical keys?
Yes. A keyless entry module paired with TRACKbox reads RFID staff cards or Sensium-issued fobs. The driver taps their card, the TRACKbox unlocks the vehicle and starts the booking, and the fleet manager is alerted that the driver has taken control. The vehicle stays locked to anyone without an authorised card.
Question 08
Can remote lock and unlock be triggered from a phone?
Question 08
Can remote lock and unlock be triggered from a phone?
Yes. Commands can be sent from the Sensium Connect dashboard or the Sensium Connect+ mobile app, so a fleet manager can unlock a vehicle from any device, anywhere. The persistent encrypted connection means the command reaches the TRACKbox in real time without any driver action or phone-to-vehicle pairing.
Question 09
What happens to the vehicle access hardware if I sell or return the vehicle?
Question 09
What happens to the vehicle access hardware if I sell or return the vehicle?
Remote lock and unlock works on owned or leased vehicles. The TRACKbox and keyless entry module are fitted with pre-assembled install looms and can be removed cleanly when you swap, sell, or return the vehicle. Talk to us about de-fit and re-fit when you cycle vehicles through the fleet.
Question 10
Can the engine disable be reversed once the vehicle is recovered?
Question 10
Can the engine disable be reversed once the vehicle is recovered?
Yes. The Disable Module is a hardware-based kill switch that prevents the starter from operating until you re-enable it from the dashboard. When the vehicle is recovered or the issue is resolved, re-enabling from Sensium Connect restores normal operation. The encrypted two-way channel acknowledges both the disable and re-enable commands.
