Q: Vehicle shifts into lock on its own

Hello. It is possible that there is an issue with the actual switch that activates the 4 wheel lock. However, it is more common that a problem with the shift lock solenoid on the transfer case is the cause of the problem you are experiencing.

It would be a good idea to have a certified technician, like one from YourMechanic, come and inspect the transfer case and its electrical components in order to pinpoint the problem and recommend necessary repairs.
