Cargo theft doesn’t wait for business hours. Trailers parked in a yard overnight, shipping containers sitting at a remote staging lot, boxcars on a siding, machines left on a job site over a long weekend — these are exactly the assets thieves look for, precisely because no one is watching them. The question every fleet and logistics operator eventually asks is simple: how do I secure what I can’t stand next to?

The BSX100 SolarLock answers that question by combining two things that usually live in separate devices — a GPS asset tracker and an electronic door lock — into a single, solar-powered unit you can control from across the yard or across the country.

One device, two jobs

Most security setups force a trade-off. A padlock keeps a door shut but tells you nothing about where your asset is or whether someone is tampering with it. A GPS tracker tells you where your asset is but does nothing to stop it from being opened. SolarLock closes that gap.

It physically locks your trailer, container, or equipment enclosure, and it reports location, movement, and security events back to you in real time. When something happens, you don’t just find out after the fact — you can act on it immediately.

Unlock it your way: remote or on site

The standout feature is flexibility in how you open the lock:

• Remotely — send an unlock command straight from the Btracking platform, or by SMS from any phone. Useful when a driver arrives at a delivery and you want to release the lock from the office without handing out keys or codes.
• On site by app — your team unlocks over Bluetooth (BLE) using the Btracking phone app.
• On site by RFID card — tap an assigned card to release the lock, no phone required.

That mix means you control access centrally while still giving field crews fast, practical ways to get in when they’re standing right there.

Built to sit outside and keep working

Remote assets don’t have power outlets, so SolarLock runs on the sun. A long-life rechargeable Li-Polymer 14,400 mAh battery, paired with efficient solar recharging, delivers roughly 8 to 12 months on a single charge — and in practice the solar panel keeps topping it off, so you’re not climbing onto containers to swap batteries.

To conserve energy and capture what matters, the device wakes on motion, so a container that suddenly starts moving triggers reporting rather than draining the battery sitting still.

The enclosure is built to resist tampering and stand up to harsh outdoor environments, and a built-in magnet mount plus optional mounting bracket and protective rubber sleeve make installation straightforward on a range of surfaces. SolarLock also ships with a choice of rope/cable lengths — 1.4 ft, 3 ft, 16 ft, 33 ft, 66 ft, or custom — so it fits everything from a tight container latch to a wide gate.

Alarms that reach you before the loss does

Security hardware is only as good as the alerts behind it. SolarLock sends you an SMS or email for the events that matter:

• Locking and unlocking
• Lock tampering
• Motion on a parked asset

If someone tries to force the lock at 2 a.m., you know at 2 a.m. — not when the trailer turns up empty.

More than a lock: a sensor hub

SolarLock has Bluetooth Low Energy built in, which lets it do double duty as a monitoring platform. Add optional wireless sensors and the same device that secures your cargo can also watch over its condition:

• Temperature (plus an internal temperature and light sensor onboard)
• Humidity
• Door open / closed status
• Wireless relays

For anyone moving temperature-sensitive freight or storing goods in containers, that’s cargo security and cargo integrity from one unit.

Simple, no-contract subscription

The hardware is backed by Btracking’s tracking platform, with monthly service starting at $12.95 and no contracts — so you’re not locked into a multi-year commitment to protect your assets. The BSX100 itself starts at $349.99, and it’s available in a North America CAT M1 version and a Global CAT 1 version for international operations.

Who SolarLock is for

If any of these sound like your operation, SolarLock was built for you:

• Fleets parking loaded trailers in unsecured or semi-secured yards
• Logistics and intermodal operators managing shipping containers and boxcars
• Construction and agriculture businesses leaving machinery and equipment on remote sites
• Anyone who needs to grant access to a driver or crew member without physically being there

Secure it, see it, control it

The BSX100 SolarLock turns a vulnerable, parked asset into one you can lock, locate, and open on your terms — powered by the sun, alerting you the moment something changes, and ready to unlock from your phone, an RFID card, or anywhere with a signal.
