IMMO OFF – Deactivation of the immobilizer for Honda models

Are you having problems with the immobilizer on your Honda, or would you like to unlock your control unit for racing, modification, or spare parts use?

We offer a reliable and lasting Immobilizer deactivation/HISS/IMMO OFF for numerous Honda models with modern ECU.

Whether it's a defective key, damaged transponder, defective ring antenna, missing lock set or conversion project – in many cases the original engine control unit can be programmed so that the vehicle starts without an active immobilizer.

🔧 Sequence

For the procedure, we usually only need the original ECU/engine control unit.

Deactivation is performed via software and is permanent – ​​depending on the model, without a functioning key, transponder or ring antenna.

The control unit will be tested, programmed, and then returned to you.

📄 Important NOTE

A valid proof of ownership of the vehicle is required for this programming.

Acceptable formats include, for example:

• Vehicle registration certificate
• Purchase agreement
• Proof of ownership
• Invoice for the vehicle or ECU

We will not perform IMMO-OFF programming without proof of ownership.

💡 Note regarding the error message in the speedometer

In some Honda models, after disconnecting the ring antenna, if components are missing, or if there are defects in the immobilizer system, an error message or warning light may still appear in the speedometer.

However, after successful deactivation, the vehicle can be started and driven normally.

Depending on the model, ECU version and speedometer unit, the display may react differently.

✅ compatibility

In principle, there is almost every Honda model with a genuine ECU/engine control unit the option to deactivate the immobilizer.

This affects many modern Honda motorcycles with fuel injection and HISS/Immobilizer system.

Examples:

• Honda CBR models
• Honda CB/CB-R models
• Honda Africa Twin models
• Honda Fireblade models
• Honda Hornet models
• Honda Transalp models
• Honda VFR models
• Honda CRF models with ECU
• many more Honda fuel-injected models

⚠️ Not suitable for old carburetor-CDI systems

For older Honda models with a classic carburetor CDI, without a modern ECU and without a corresponding immobilizer system, this type of software-based deactivation is not possible.

Whether your model is suitable depends on the installed control unit and the generation of electronics.

✅ Original Honda ECU/engine control unit
✅ valid proof of ownership

Shipping the vehicle is not necessary in most cases.
