1) Are you sure you replaced the right switch? The detente switch in the shifter is generally wired NC instead of NO and will cause I-key issues if it's replaced incorrectly. If you trace the wires, the solenoid switch will wire to the solenoid and ground, the detente switch will wire to either the shift handle or direct to the shifter connector.
2) Most of the early I-key setups with faux key cylinders instead of a button have a cable connecting the cylinder to the shifter, and if it's out of adjustment it can prevent proper operation of the cylinder and fob.
If that's all good, do some old school diag on your repair. The shift solenoid gets power through the brake switch on the high side, make sure the power is getting there. On most shifters the solenoid coil will read at least 20 ohms, and the low side of the solenoid will show a good ground in the Park position if the switch is working properly.
