⭕ This solution requires KLON programming
KLON is a two-stage programming process, and it exists for a good reason:
it means you don't have to sacrifice one of your keys. On a modern
vehicle a spare key can cost several hundred dollars, so this saves real money.
Completing it requires a iDatalink ADS-USB programming tool, which is not
included. There is no alternative method. The
ADS-USB-ECO is a lower-cost option that does the same job.
Buying from us? This usually isn't a problem. We pre-program modules
before they ship on most vehicles, so it arrives ready to install. Just tell us your
year, make and model at checkout.
