I might have to pull it apart again but I didn't think it would be a connection thing since some of them work when I push them rather hard
If the pads under the membrane are clean, there could be another cause as
medvedev states.
Try bridging the pads while apart and powered on, that might confirm a connection problem, not membrane.
Trace the pads connections to see if you can find a common connection that might point to a group of bottons that won't work. Check for cracked traces/PCB.
Not sure on the 1052E setup, but there is often a loom or ribbon cable from the front panel PCB to the main board. Check the soldering of the sockets for cracked or bad joints.
Write stuff down, make diagrams.
