How easy is installation and programming?

Oktiger sensors come pre-programmed to the correct 433MHz profile, so no special coding is required during installation. After physically mounting the sensor and reassembling the tire, follow your vehicle’s relearn procedure or use an OBD2 TPMS tool to activate pairing with the ECU.

• Pre-programmed—no need to write new IDs into the sensor.
• Relearn via owner's manual procedure, TPMS scanner, or OBD2 tool.
• Important: technician must only ACTIVATE/RELEARN, not reprogram the sensor.
