nuck Report post Posted July 8, 2020 Either by a dealer of by yourself? My Lexus and BMW keys had to be new according to the dealers, however I have seen a locksmith encode the Lexus key so there is that. I have never heard of any similar issue with the MKX except you need two smart keys in your possession to encode a 3rd. Share this post Link to post Share on other sites

It's not that easy to code the keys on your own, you need the software to do it and it's not readily available. So, it's always important to contact a locksmith or dealership for new smart card key.

If you have both registered keys available, the process described in the video will program a third key. Share this post Link to post Share on other sites
