Jaguar EPace - key-less malfunction

I bought an ePace Dynamic, HSE (with key-less start and door lock) from CMH in October 2018. I discovered 6 months later that the car was actually registered in April 2018 so my warranty and terms of service were affected. CMH undertook to extend the warranty on their own account - is that good enough? BUT the problem with the car, from early on, is that the key-less feature doesn't work (most of the time). Four returns to CMH and still pathetic. Anyone else have the same problem?
