Transmitter Keyless,replacement Key Blank, No Transponder Chip and Electronics/Battery,
Best replacement for broken or worn keys, or great for an additional key.
Take the internal electronics (include immobilizer/transponder chip) from original remote and place them to our key shell, then it is OK! There's no programming needed.
This item isn't a remote key, it's just a remote key shell. NO interior (remote/electronics/ignition or transponder chips) unit inside.
