Compatibility Overview: What Works with Your BLAZER
The Chevrolet Blazer (2019–2024 models) comes standard with a direct TPMS system that monitors each tire individually. The system uses clamp-in sensors transmitting at 433MHz. Most aftermarket replacements are pre-programmed (they come ready to pair without cloning) or programmable with a tool.

How to Verify Fitment Before You Buy
Step 1: Confirm Your Blazer’s Year and Trim
The BL-ST-097 covers 2019–2024 Chevrolet Blazer (all trims: LS, LT, RS, Premier, and SS). If you have a 2018 or earlier Blazer, this sensor will not work — those models use a different system (315MHz for some older years).
Step 2: Check the OE Number on Your Old Sensor
Remove the wheel and look at the silver sensor bolted to the valve stem. The OE part number is printed on it. Common numbers that match the BL-ST-097:
- 13530661
- 13533166
- 13538565
- 13538566
- 13538761
- 13549707
If your sensor’s number is one of these, the BL-ST-097 is a direct plug-and-play fit.
Step 3: Verify the Frequency
All modern Chevrolet Blazer TPMS sensors run on 433MHz. You can confirm by checking the vehicle’s owner’s manual (under “Tire Pressure Monitoring System”) or by using a TPMS diagnostic tool to read the sensor ID and frequency.
Step 4: Re-Learning After Installation
Once you replace the sensor, the system needs a re-learn procedure. This typically requires a TPMS activation tool (or you can drive the car at 20+ mph for 10 minutes — some models auto-relearn). If you have a scan tool like Autel or Bartec, follow the on-screen prompts. The BL-ST-097 is pre-programmed, so no cloning is required — just install and re-learn.
Common Compatibility Pitfalls (What to Avoid)
- Wrong frequency: Do not buy a 315MHz sensor for a 2019+ Blazer — it will not communicate.
- Aftermarket vs. OE: The BL-ST-097 matches OE specifications exactly. Some cheap knockoffs may have a different valve stem length or fail to seal.
- Trim-specific variations: The Blazer RS and Premier have the same sensor part numbers. No special exceptions.
Recommended Part
For a direct replacement that eliminates guesswork, use the BL-ST-097 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Buick, Cadillac, Chevrolet, Nevo | OE# 13530661, 13533166, 13538565 — it covers all 2019–2024 Blazer models and multiple GM cross-references. It’s pre-programmed, so you don’t need to copy sensor IDs.
FAQ
Does the BH-Sens BL-ST-097 fit the Chevrolet Blazer EV?
The Blazer EV (2024+ models) uses a different TPMS frequency (likely 433MHz as well, but confirm). The BL-ST-097 is designed for ICE Chevrolet Blazer models. We recommend checking the EV owner’s manual or contacting the manufacturer for EV-specific sensors.
Can I install the BL-ST-097 myself?
Yes, if you have basic tools: a tire demount machine or a shop to break the bead, and a torque wrench (tighten to 4–5 N·m or 35–44 lb-in; check your manual). After installation, the re-learn procedure may require a trip to a tire shop if you don’t own a TPMS tool.
Will using a pre-programmed sensor void my Blazer’s warranty?
No — aftermarket sensors that meet OE specs (like the BL-ST-097) are legal replacements. GM cannot void the warranty because you used a compatible aftermarket part. Keep the receipt for documentation.
What if my Blazer shows “Service Tire Pressure System” after installing a new sensor?
That typically means the sensor was not learned. Re-run the re-learn process. If it still fails, the sensor may be defective or the battery may be dead (though BH-Sens sensors have a 5–7 year battery life). Double-check the OE number match.
