Keyless Transmitter Programming/Deleting - Manual Method: Notes
2008 Honda Odyssey EXSECTION Notes
NOTE:
The keyless transmitter attaches to the ignition key and is separate from the immobilizer transponder. It is not necessary to use the HDS when replacing or deleting an existing transmitter.
- Adding a key (transponder) can only be done with the HDS. If the key being added has a new remote transmitter, it can be programmed with the HDS at the end of the "ADD A KEY" function ( IMMOBILIZER KEY REGISTRATION ).
- If one or all keys (transponders) are lost, the remote transmitters must be deleted manually. This will assure that all of the old keyless transmitters have been cleared from the keyless receiver unit memory.
- When replacing the power window master switch (has built-in keyless receiver unit), you must have all of the remote transmitters that need to be programmed to the car.
- The keyless receiver unit can only store 5 keyless transmitters.
- During programming, pushing the same remote button 5 times will delete all other remotes.
