Understanding LX TPMS Compatibility
LX vehicles have used TPMS sensors since the early 2000s, but not all sensors are interchangeable. The BH-Sens BL-ST-072 (SKU: BL-ST-072) is designed for 314.9–315MHz systems, which covers the vast majority of LX models sold in North America and select global markets. However, LX switched to a different frequency band on certain platforms after 2018, so year coverage is critical.
Frequency Matters: 315MHz vs. 433MHz
LX’s TPMS systems are split into two main frequency bands:
- 315MHz – Used on most LX models from 2005 to 2018 (some platforms up to 2020)
- 433MHz – Introduced on newer LX platforms (2019+ on certain models)
The BL-ST-072 operates at 314.9MHz and 315MHz. If your LX was built before 2019, this sensor will likely work—provided the OE part number matches. For 2019+ LX models, confirm the frequency via your vehicle’s service manual or by reading the original sensor label.
How to Verify Fitment Before Buying
Step 1: Locate Your Vehicle’s OE Part Number
The safest way to confirm fitment is to find the OE part number printed on your existing sensor. For LX vehicles, common OE numbers include:
- 12768826
- 13516164
- 13540604
- 13544443
- 13581558
- 13586335
- 13589597
- 13598771
- 13598772
- 15254101
- 15268606
- 15921013
- 20922900
The BL-ST-072 covers all these OE numbers. If your LX’s sensor has one of these numbers stamped on the metal or plastic housing, the sensor is a direct fit.
Step 2: Check Your LX’s Year and Trim
Below is a quick reference for LX model compatibility. This table is based on common platform usage—always verify with your VIN.
| LX Model | Approx. Years with 315MHz | Notes |
|---|---|---|
| LX Sedan (base) | 2005–2018 | Most trims use 315MHz; 2019+ may use 433MHz |
| LX SUV (5-seat) | 2007–2019 | Check rear hatch wiring for sensor location |
| LX SUV (7-seat) | 2008–2020 | Some 2020 models still use 315MHz on base trims |
| LX Crossover | 2010–2018 | 315MHz standard; 2019+ switch to 433MHz |
| LX Truck | 2006–2017 | All 315MHz; 2018+ use 433MHz |
Important: LX sometimes used different sensors for summer vs. winter tire sets. If your vehicle has an aftermarket TPMS system (e.g., dealer-installed), the frequency may differ from the factory spec.
Step 3: Confirm the Sensor Programming
The BL-ST-072 is a programmable sensor. It can be cloned to match your LX’s original sensor ID, or it can be auto-learned by the vehicle’s TPMS module. For most LX models (2008–2018), the sensor will work with the standard TPMS relearn procedure:
- Inflate all tires to the recommended pressure
- Use a TPMS tool to trigger each sensor in sequence (LF, RF, RR, LR)
- The vehicle’s system will acknowledge each sensor with a horn honk or light flash
For older LX models (2005–2007), you may need a dealer-level scan tool to program the sensor IDs. The BL-ST-072 is compatible with most universal TPMS tools (Autel, Bartec, ATEQ).
Why OE Number Matching Is Your Best Bet
Many LX owners try to buy TPMS sensors based on vehicle year alone—and end up with sensors that don’t communicate. LX used multiple sensor suppliers (including Baolong, Schrader, and Continental) across the same model years. A 2015 LX Sedan might have a Baolong sensor (OE 13540604) from the factory, while a 2015 LX SUV might use a different brand with a different OE number.
The BL-ST-072 is built by BH-Sens (Baolong Technology), which is the OEM supplier for many LX sensors. If your LX originally had a Baolong sensor, this is a direct OEM replacement. If your LX had a different brand, the sensor can still work if it’s programmed to the correct frequency and ID.
Installation Tips for LX Vehicles
- Valve stem type: LX uses rubber snap-in valves on most models (except some high-trim SUVs with metal valves). The BL-ST-072 comes with a standard rubber valve stem.
- Torque spec: Tighten the valve stem nut to 4.5–6.0 Nm (check your manual). Overtightening can damage the sensor.
- Battery life: New BH-Sens sensors typically last 5–7 years. If your LX is older than that, replacing all four sensors at once is recommended.
- Relearn after replacement: Drive the vehicle for 10–15 minutes above 25 mph after installation. Some LX models require a manual relearn using the TPMS reset button (usually under the dash or in the glove box).
Recommended Part
For LX owners needing a reliable, OE-quality TPMS sensor at a fraction of the dealer cost, the BL-ST-072 | BH-Sens 314.9, 315MHz TPMS Tire Pressure Sensor | Fits Brilliance, Buick, Cadillac, Chevrolet, Gmc & 3 More | OE# 12768826, 13516164, 13540604 covers 14 OE part numbers, works with LX models from 2005–2018, and is programmable for universal fitment. Always verify your OE number before ordering.
FAQ
What if my LX’s OE number isn’t listed for the BL-ST-072?
If your LX uses a sensor with an OE number not in the list (e.g., 13598771 or 20922900), the BL-ST-072 may still work if the frequency matches. Check the original sensor’s frequency marking. If it’s 315MHz, the BL-ST-072 can be programmed to match. If it’s 433MHz, you need a different sensor.
Can I use the BL-ST-072 on a 2020 LX?
It depends on the platform. Some 2020 LX base trims still use 315MHz sensors, but most 2020 LX models have switched to 433MHz. Locate the OE number on your current sensor and compare it to the list. If your OE number is not in the list, and the sensor frequency is 433MHz, the BL-ST-072 will not work.
Do I need a special tool to program the BL-ST-072 for my LX?
Yes, you need a TPMS programming tool (Autel, Bartec, or similar) to clone or program the sensor IDs. Some tire shops can do this for a small fee. The sensor comes unprogrammed; you must set the correct ID and frequency before installation. However, on LX models from 2010 onward, the sensor may auto-learn after driving—check your vehicle’s TPMS relearn procedure.
Will the BL-ST-072 work on LX vehicles sold outside North America?
In most cases, yes. LX vehicles sold in Europe, Asia, and the Middle East also use 315MHz sensors on many models. However, some markets use 433MHz as standard. Verify the frequency on your original sensor before purchasing. The BL-ST-072 is designed for 314.9/315MHz systems only.
