Key fob partially working 2012 CLS550
I have two key fobs for my car. One works totally fine (keyless go for all doors and trunk and push button start).
The other “problem” key only works in some ways:
works: push button start, fob buttons lock/unlock/trunk
DONT work: keyless go for all four doors and trunk.
I changed battery and tried resynching the key following these directions:

seems like all the suggestions only are around, fuses, cables, handles, etc. all don’t make sense with one key working fine.
help!
