Key remote works intermittently.

What is your question?

When key isn’t working the unlock button on drivers side will not unlock passenger door and trunk release on dash does not work either. The vehicle will start with key and this reactivates the use of the trunk release and door lock inside the vehicle. Key remote was not remedied by changing battery in key. Ordered a new key and tried to program it but it would not program the ignition. Kept throwing error code. Do I have a bigger issue than the remote? Where do I go from here?

What makes this problem better or worse?
