This is not a fault with the remote control system as manually it is also not functioning correctly. I would suggest scanning for trouble codes within the Body Control Module system.
Possible causes for such problems are :
1. Wiring circuit. Connections could be bad somewhere and if any repairs were done prior to this, those are the areas to check. A poor ground would also cause this.
2. Faulty Body Control Module.
3. Bad door lock actuators.
