A dedicated tool that activates compatible TPMS sensors during your vehicle’s relearn procedure — useful after a tire rotation, a seasonal wheel swap or a sensor replacement.
01 · Fitment first
✅ Confirm your exact vehicle before you order
PainA brand name alone does not confirm compatibility.
FixMatch your model, year and any listed VIN, regional or variant notes against all six supplier fitment lists below.
Not sure about an entry? Confirm your exact vehicle and sensor compatibility before ordering — especially if a model name, VIN note or regional variant is unclear.
02 · Position matters
📍 Get close to the valve stem
PainAn activation tool only works when the antenna is close enough to the sensor.
FixPosition the antenna near the tire sidewall beside the valve stem, then follow the tool instructions and your vehicle’s relearn procedure.
03 · A clear relearn routine
🔁 Enter. Activate. Confirm.
PainRelearn steps vary by vehicle, so it helps to follow one fixed order.
FixStart your vehicle’s relearn mode, activate each sensor in the specified order, then check for the completion signal.
04 · Purpose-built controls
🔋 TX and LOWBAT indicators
PainYou want to know the tool did its part before moving to the next wheel.
FixAn I/O switch plus TX and LOWBAT indicators keep the tool simple to operate during the procedure.
05 · Keep it ready
🛠️ Useful now, ready for the next tire job
PainTire rotations, seasonal wheel changes and sensor replacements come around again.
FixGive this tool a place in your garage so it is on hand for the next compatible relearn.

Before you buy
Your questions, answered.
Will it work with every vehicle?
No. Match your exact model, year and any listed variant or VIN notes against the fitment images. Also confirm compatibility with your vehicle’s sensors and relearn procedure.
Can it clear any tire-pressure warning?
No. Relearning sensor positions does not correct low tire pressure or repair a failed sensor. Check tire pressures and address faults according to your vehicle’s instructions.
Do I need a separate tool for each tire?
No. The same tool can activate compatible sensors one at a time during the relearn procedure. Follow your vehicle’s required wheel sequence.
How do I put my vehicle into relearn mode?
Consult the owner’s manual or service instructions for your exact vehicle. The entry steps and completion signals vary by model.
What if a sensor does not respond?
Check tool power, antenna position, vehicle relearn mode and sensor compatibility. Follow the tool and vehicle troubleshooting instructions; a failed sensor may require separate diagnosis.

Bought this after rotating the tires on my Sierra. Put the truck in relearn mode, worked my way around the wheels, and every sensor activated on the first pass. Beats making a trip to the dealer for one small job.

Simple tool that does one job. The TX light let me know each activation went through so I wasn't guessing. I checked the fitment charts before ordering and my year and model were listed.

I'm not a mechanic and I still managed this. Followed my vehicle's relearn steps, held the tool by the valve stem, and went around in order. Nice to have on hand for winter wheel swaps.

Read the compatibility list carefully first — my car was on it, my husband's wasn't. Good little tool once you confirm the fit.
