My 2014 Landrover Discovery 4 was stolen when they picked the lock and paired a new key with it using the ODB port. As it is keyless start, that is all they needed to drive it away. I still have both of the original keys.

The manufacturer's response was about people doing illegal things. It seems a retrograde security step from older vehicles where you needed the key to get the immobiliser to work, to the new vehicles where if you can get in, you pair a new key and drive it away in minutes.

In my head, it should be a requirement that you

• have an existing working key present, or
• enter a pin number somewhere

before being able to pair a new key.

Is there a technical reason why this should not be the case?

To recap, this question is only covering pairing new keys and keyless start, this is not asking about keyless entry.
