So I have a 2016 LR4 and I have lost the key fob and it is a complete push button start. I have another Land Rover key that I was trying to see if I can program but I was told that without the key that did work I have to be replace the DCM and KVM which will run about $3,000.

Anyone know if it's possible to reprogram a key without changing the KVM and DCM?

Again, the original key that started with is lost and there are no additional functioning keys.
