Look no dealer can change your entry code because it requires a module change. On all Factory entry modules for drivers door keyless pad, It 5 digit code is on the module it self.
Locate it or the original card from owners manual its there as well . Scanning the system from a Module Scanner will also reveal its code. Most dealers charge up to $200.00 for that service

You can actually add your own code if you know the original code
