Keyboard not working properly after switch replacement

Hello.

I just finished replacing the switches on my Masterkeys Pro keyboard. The problem is that now 5 switches do not work, more precisely tab, caps lock, q, a and f8. All the switches look soldered correctly and I didn't notice any lifted pads. I tried to put back on one of the original switches but it didn't work either. One thing I noticed is that if I touch one of the pads where the non-working switched are soldered to, the keyboard does register an input, so I guess the pcb is fine.
Still, I can't figure out what exactly went wrong. Can anybody help me figure this out, please?

Thanks.

Do you have a multimeter? If so, can you use it to check continuity?

No, I don't have one.

Can you attempt to handwire the connections where the traces normally run for the switches that aren't working and let us know if that works?

I hand wired the tab switch to the tilde one. The tab still does not work, but the tilde now work as the tab key... I soldered the left pins.
