Video: How to program a key on Honda FR-V

This video shows how to add a new key by following ignition ON/OFF sequences guided by the diagnostic tool.

Technical overview

Vehicle	Honda FR-V
Year	2006
System	Immobilizer (IMMO 3)
Procedure type	Key programming (Add key)
Difficulty	Easy
Time required	~5–10 minutes
Prerequisites	Working key, compatible scanner with IMMO

Step-by-step procedure

Connect the diagnostic tool

Plug the scanner into the OBD2 port
Turn ignition ON using an already working key

Enter immobilizer menu

Open:
IMMO / Key Programming / Anti-theft system
Select vehicle manually if auto-detect fails

Select “Add key” function

Choose: Add key / Program additional key
Follow on-screen instructions

Follow ignition cycle prompts

The scanner will ask you to:
- Turn ignition OFF
- Turn ignition ON
- Repeat multiple times

⚠️Warning: This is normal, timing matters. Follow the ignition prompts exactly when the scanner asks.

Insert the new key when prompted

The scanner does not always say when to insert the new key. Use the key you want to add after the first ignition OFF prompt.

Switch from the original key to the new key
Turn ignition ON

Wait for confirmation

Scanner will confirm successful programming
Immobilizer light should behave normally

Test the new key

Turn ignition ON
Start the engine
Verify no immobilizer warning

Additional information & compatibility notes

This procedure is guided entirely by the scanner, no manual coding required If the process fails:

Retry with correct timing during ignition cycles
Ensure battery voltage is stable

Some Honda systems may:

Require all keys to be present
Delete old keys during programming (depends on tool/software)
