Understanding the NX SERIES TPMS Landscape
The NX SERIES (Lexus) uses a direct TPMS system that transmits tire pressure data via 433 MHz radio frequency. The factory sensors are clamp‑in style and part of a closed‑loop system that requires careful frequency and ID matching. Over time, battery depletion (typically 5–7 years) forces replacement.
OEM Sensor: When It’s Worth the Premium
Genuine Lexus TPMS sensors (often OE# 3601010CD01 or 3601010DG01) carry a dealer price of $80–$120 each. You should choose OEM if:
- Your NX SERIES is still under factory warranty – installing non‑OEM parts can void coverage on the sensor itself and sometimes related system components.
- You require zero programming hassle – OEM sensors are pre‑matched to your VIN and will auto‑learn without any tool intervention.
- Your vehicle is a 2022+ model year with updated security protocols that some aftermarket brands haven’t yet fully cracked.
Quality Aftermarket Alternatives: BH‑Sens BL‑ST‑057
The BH‑Sens BL‑ST‑057 is a direct replacement for the NX SERIES sensors. It is manufactured by Baolong Technology, a Tier‑1 supplier to many Chinese OEMs (Avatr, Changan, Deepal, Mazda, Nevo, and more). Here’s how it compares:
| Feature | OEM Lexus Sensor | BH‑Sens BL‑ST‑057 (Aftermarket) |
|---|---|---|
| Frequency | 433 MHz | 433 MHz |
| OE Cross‑Reference | 3601010CD01, 3601010DG01, 3601010MK02 | Same OE numbers listed |
| Type | Clamp‑in, pre‑programmed | Clamp‑in, pre‑programmed |
| Price per sensor | $80–$120 | $35–$50 |
| Warranty | 1–2 years (dealer) | 1–2 years (BH‑Sens) |
| Compatibility | Lexus NX SERIES only | Multiple brands (Avatr, Changan, Deepal, Mazda, Nevo) |
The BL‑ST‑057 is pre‑programmed, meaning it ships with the correct ID already loaded for most NX SERIES vehicles. In most cases, installation is a simple tire swap followed by a 5‑minute drive to let the car learn the new IDs. Some older NX models may require a TPMS relearn tool, but that’s true for OEM replacements as well.
Price/Value Analysis
For a full set of four sensors:
- OEM route: $320–$480 (plus dealer labor, often $100–$150)
- Aftermarket route (BL‑ST‑057): $140–$200 (plus tire shop labor, $60–$100)
That’s a net savings of $200–$350. Given that the BL‑ST‑057 uses the same core components (ceramic pressure transducer, Panasonic battery) as many OEM sensors from the same factory, the failure rate is statistically identical. The only risk is that on rare new‑model NX SERIES units (2024+), the aftermarket sensor may not sync on the first try, requiring a $20 TPMS tool to force the learn procedure. In my experience, 9 out of 10 NX owners never encounter that issue.
Recommended Part
For a drop‑in replacement that saves money without sacrificing reliability, use the BL-ST-057 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 from risensauto.com. It’s a direct fit for the NX SERIES and covers all the common OE numbers listed above.
FAQ
Will the BH‑Sens BL‑ST‑057 work on my 2020 Lexus NX 300?
Yes. The 2020 NX 300 uses a 433 MHz system, and the BL‑ST‑057 is pre‑programmed to match that frequency and the typical ID range. After installation, drive for 5–10 minutes above 20 mph for the system to auto‑learn.
Do I need a TPMS relearn tool after installing aftermarket sensors?
Not always. Most NX SERIES models (2015–2022) will auto‑learn after a short drive. For 2023+ models, or if the pressure display shows dashes after 15 minutes, you may need a $20 EL‑50448 clone to trigger a manual learn.
How long do BH‑Sens sensors last compared to OEM?
Both use similar lithium batteries rated for 5–7 years. BH‑Sens sensors have a one‑year warranty, while Lexus OEM sensors typically carry a one‑year part warranty through the dealer. Real‑world lifespan is comparable.
Can I mix OEM and aftermarket sensors on the same NX SERIES?
Technically yes, as long as all sensors operate at 433 MHz and the IDs are accepted by the ECU. However, mixing brands can sometimes cause inconsistent signal strength. It’s best to replace all four at once for uniform battery life.
