GPS Smart Lock IL002 – Complete FAQ & Integration Guide
Frequently Asked Questions (FAQ)
In this section, we answer the most common questions about our GPS smart lock. As a result, you can quickly decide if this solution fits your logistics or asset tracking needs.
1. What is a GPS smart lock and how does it work?
Answer:
A GPS smart lock is an intelligent locking device that combines a physical lock with GPS tracking, GPRS communication, and sensors.
How it works:
- The lock connects to your tracking platform via GPRS or SMS.
- It sends real-time location data (latitude, longitude, speed, direction).
- You can remotely lock/unlock using RFID, password, or platform command.
- If someone tampers with the lock, you receive an instant alert.
In other words, it’s a lock that talks to you.
2. Do I need a special GPS tracking platform?
Answer:
Not necessarily. The device uses an open TCP/IP protocol with ASCII commands and binary data formats.
- You can integrate it with your existing GPS platform using our protocol manual.
- Alternatively, we can recommend compatible platforms.
- The lock also works with SMS commands from authorized phone numbers.
As a result, you are not locked into a proprietary system.
3. Can I unlock the device without an RFID card?
Answer:
Yes. The GPS smart lock supports three unlock methods:
| Method | How it works |
|---|---|
| RFID card | Swipe an authorized key (up to 50 keys supported) |
| Password | Enter a 6-digit code (default 888888, changeable) |
| Remote command | Send (P43,888888) via GPRS or SMS |
For example, a driver can unlock using a password if they forget their RFID card.
4. What kind of alerts does this GPS lock provide?
Answer:
The device supports 10 independent alert types. Each alert can be sent via GPRS, SMS, or both.
| Alert Type | Trigger Condition |
|---|---|
| Lock rope tamper | Rope cut or unplugged |
| Unauthorized RFID | Swiping an unrecognized card |
| Unlock alert | Successful unlock event |
| Wrong password | 5 consecutive incorrect attempts |
| Vibration | Shock or cutting attempt |
| Enter geofence | Asset enters a virtual boundary |
| Exit geofence | Asset leaves a virtual boundary |
| Low battery | Battery level drops |
| Back cover opened | Physical tampering |
| Motor fault | Mechanical or electrical failure |
5. What is geofencing and how do I use it?
Answer:
Geofencing is a virtual boundary you draw on a map.
- The lock supports up to 10 polygon geofences (up to 50 nodes each).
- When your asset enters or exits a geofence, you receive an instant alert.
Use cases:
- Alert when a truck leaves the warehouse
- Notify when cargo arrives at customs
- Trigger an alarm if a container enters a high-risk area
In addition, you can restrict unlocking to inside a specific geofence using the command in usermanual.
6. What happens if the device loses cellular signal?
Answer:
The lock has a blind zone data buffer.
- It stores up to 28,000 position records and 2,400 lock/unlock events in internal flash memory.
- When the signal returns, all data is uploaded automatically in FIFO (first-in, first-out) order.
Consequently, you never lose critical data — even in tunnels, remote highways, or basements.
7. How long does the battery last?
Answer:
Battery life depends on your configuration.
- Default settings: Sleep 30 minutes / Awake 10 minutes → weeks of operation.
- Real-time tracking mode: Continuous reporting → shorter battery life.
- Power-saving mode: Minimal reporting → extended battery life.
The device reports battery voltage and percentage in every position update.
It also detects charging status for rechargeable configurations.
*For example, you can adjust the reporting interval using the P04 command to balance battery life vs. real-time visibility.*
8. Can I update the firmware remotely?
Answer:
Yes. The GPS smart lock supports Over-The-Air (OTA) firmware upgrades using the P99 command.
- You specify the OTA server IP and UDP port.
- The device downloads and installs the new firmware automatically.
- No physical access is required.
As a result, you can add new features and security patches without visiting each device.
9. Does the device work internationally?
Answer:
Yes. The lock features dual SIM slots with single standby operation.
- It automatically selects the SIM card with the stronger network signal.
- You can configure APN settings for different carriers using the P06 command.
- The device stores data during network gaps and uploads later.
Therefore, it is ideal for cross-border logistics and international freight.
10. How do I integrate this lock with my existing system?
Answer:
Integration is straightforward thanks to the open protocol.
Step 1: Set your server IP and port using command (P06,1,<YOUR_IP>,<PORT>,<APN>,,,0)
Step 2: The device connects via TCP and sends binary position data starting with 0x24 ($)
Step 3: Parse the data using our field definitions (latitude, longitude, status, alerts, etc.)
Step 4: Send commands back to the device using ASCII format, e.g., (P35) to acknowledge alerts
For example, a complete Python parsing script is available in our protocol manual.
11. What is the Unit ID and where do I find it?
Answer:
The Unit ID is the last 10 digits of the device‘s IMEI number.
- IMEI example:
860298043396604→ Unit ID:8043396604 - It is used as the device identifier in all command responses and data transmissions.
12. Can I send commands via SMS instead of GPRS?
Answer:
Absolutely. SMS is a backup communication channel.
- Send any command (e.g.,
(P02),(P43,888888)) from an authorized phone number. - The device will execute the command and respond via SMS.
- This is especially useful when GPRS is unavailable or for simple queries.
In addition, you can configure up to 5 authorized phone numbers using the command.
13. How do I reset the device to factory settings?
Answer:
Use the P13 command:
(P13) → Response: (8043396604,P13)
What is preserved: Host IP, port, APN, and authorized phone numbers.
What is reset: All other parameters (reporting intervals, alert settings, RFID keys, password, etc.).
As a result, you can recover from misconfiguration without losing network connectivity.
14. What is the difference between power-saving mode and real-time tracking mode?
Answer:
You can switch between modes using the P00 command.
| Mode | Behavior | Best for |
|---|---|---|
| Power-saving mode (default) | Sleeps 30 min, wakes 10 min, responds to external wake-up sources | Long-haul logistics, battery-sensitive applications |
| Real-time tracking mode | Stays awake, reports position at short intervals (5–60 sec) | High-value cargo, real-time monitoring |
| SMS mode | Relies primarily on SMS commands | Areas with poor GPRS coverage |
For example, you can use power-saving mode on a cross-country truck, then switch to real-time mode when entering a high-risk city.
15. Is technical support available for integration?
Answer:
Yes. Our team provides:
- Complete protocol manual (V2.4) with command examples
- Sample code for parsing binary position data
- Command reference cards for quick lookup
- Email and chat support for integrators
Therefore, you are never alone during the integration process.
16. How much is the online tracking platform monthly fee?
Answer: No monthly fee, in other words, that means you can track your car for free in our online tracking platform only if you purchase our device.
17. Is the installation too complex for install by myself?
Answer: No, it isn’t. The vehicle security system installation is not that complex as it usually involes connecting wires with the vehicle’s power, ACC line and ground wire. What’s more, we provide detailed installation manuals as well. And if you are not familiar with automotive electrical systems, maybe a professional technical is bettter. And we also provide 7/24 online technial support.
18.What does the IP66 waterproof mean?
Answer: IP66 means the GPS tracker with alarm device is completely dustproof and waterproof. It also means that can install in areas like the engine compartment where water and dust is possible.
19. How long does the remote controller battery last?
Answer: Normally 1-2 years. Or, you will get notification when the battery power is low.
