Quick Answer: For most BYD vehicles (2025+), a quality aftermarket TPMS sensor like the BH-Sens BL-ST-096 delivers identical fitment and function to the genuine BYD part at roughly half the cost. Unless your car is still under factory warranty or you need a dealer-only programming session, aftermarket is the smarter buy.
What to Check Before You Buy
Before picking a sensor, confirm three things: your BYD model year (2025+ for this sensor), the original OE number (EUEA3609200B or 110964), and whether your car uses 433MHz or 315MHz. The BL-ST-096 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD (2025+) | OE# EUEA3609200B, 110964, BLST096 operates at 433MHz, matching the latest BYD systems. Also verify that your tire pressure monitoring system supports auto-learn or universal relearn tools — most 2025+ BYDs do.
OEM vs Aftermarket: The Real Differences
| Criteria | OEM (BYD Genuine) | Aftermarket (BL-ST-096) |
|---|---|---|
| Price per sensor | $60–$90 | $25–$35 |
| OE number match | Exact | Covers EUEA3609200B, 110964, BLST096 |
| Build materials | Factory-sourced | Equivalent brass valve, sealed electronics |
| Warranty | 1–2 years (dealer) | 2–3 years (aftermarket) |
| Programming | Dealer scan tool required | Works with Autel, Bartec, or DIY relearn |
| Availability | Dealer order, 2–7 days | In stock, shipped same day |
The only real quality gap used to be battery longevity. Modern aftermarket brands like BH-Sens use the same Japanese battery cells as OEM, and independent tests show 5–7 year lifespans. The plastic housing and valve stem materials are virtually indistinguishable.
Price/Value Analysis
Replacing all four TPMS sensors on a 2025 BYD Atto 3 or Seagull costs about $320 at the dealer (parts + labor). With the aftermarket BL-ST-096, that drops to around $120 for the sensors and a quick tire shop installation. That’s a 62% savings. The catch? If your BYD is still under the original 6-year/100,000 km warranty, any non-OE part could theoretically void coverage for that specific system. Check your local dealer’s policy — most only deny claims if the aftermarket part caused the failure, which is rare with a properly matched sensor.
Where to Buy
Skip the dealership mark-up. Longwei Parts stocks the BL-ST-096 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD (2025+) | OE# EUEA3609200B, 110964, BLST096 pre-programmed or as a blank that can be cloned. Many shops will mount and program it for $15–$20 per wheel. If you’re a shop owner, keep a dozen on hand — they work across multiple BYD platforms (Han, Tang, Yuan, etc.) and drastically reduce customer wait times.
Bottom Line: For a 2025+ BYD with a dead TPMS sensor, the BL-ST-096 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD (2025+) | OE# EUEA3609200B, 110964, BLST096 is a reliable, cost-effective replacement that matches OE fitment and performance. Skip the dealer markup unless you’re chasing a warranty claim.
