If both flip keys quit working at the same time most likely there is an internal electrical fault with the control unit/ecu for the power locks.In some cases this is the remote control door lock receiver or another ecu at fault internally needing replaced then programmed.I would start with having the fault codes checked to see what codes are set for this model here and if any codes are set those codes will need diagnosed to locate and repair this issue here.

It is odd for both of these to fail like this so short after the vehicle was built.This doesnt sound like a program or relearn issue here but more like a fault with the receiver or ecu that receives the signal from the remotes/fobs themselves.You can try to hold the lock and unlock down on the key remote standing next to the vehicle to see if this relearns the remote as this will on some models.
Other then this you will need to have the fault codes checked with a scan tool or computer that plugs into your vehicle to see what codes are set and if any are set they will need diagnosed to locate and repair the fault here.If no codes are set on a newer model like this here on most models this may require the use of a dealers scan tool or computer to reprogram the remotes.
