Let’s be clear right away: if your CK-3 QC struggles to detect the sensors, it’s not a product defect. It’s simply a matter of distance… and that’s easy to work around.

Key point to understand:

• If the sensor is more than 1.60 m away, pairing may become unreliable


• But once connected, it works perfectly, even beyond 2 m

So the trick is simple: temporarily bring the sensor closer during pairing.

Simple and effective method

Use the front wheel to pair… both sensors. Yes, even the rear one.

Step 1: Pair the rear sensor

• Take the “rear” sensor


• Place it on the front wheel valve (without tightening fully)


• Start pairing


• Fully tighten the sensor → the small “pschit” from pressure activation triggers detection

Once paired, you can reinstall it on the rear wheel

Step 2: Pair the front sensor

Same process, nothing easier:

• Position the sensor on the front wheel


• Start pairing


• Tighten to trigger detection

And that’s it.

Summary

• Problem = distance during pairing


• Solution = temporarily bring the sensor closer


• Once paired = works perfectly, no real distance limitation

With this method, you eliminate 100% of pairing issues.
Simple, logical… effective.
