The keys are fine.
The original spare has hardly ever been used and the batteries are new.
The one that I have always used, has new batteries and the contacts are not compromised and making contact fine.
Both keys red diod lights up when pushed.
The car recognizes that the key is correct as the car start and performs fine.
I have used the drivers side door lock/unlock before and never had an issue with it locking the passanger and trunk locks as it should.
I knwo the pumps in the doors and hatch are working as when I pressed the lock/unlock button on dashboard everything works as should.
This all came about when I had a bad/dead car battery and replaced with a new one.
I'll check voltage today.
