I replaced my speakers on the laptop and was re-assembling the laptop but had some difficulty getting the keyboard flat ribbon cable inserted into the connector on the main board.

Is there a special tool or technique to doing it at all?
I had it connected a few times but some of the keys [ie: Q to U, A to K etc] on the left half of the keyboard did not work.
Re-inserted the cable and got those to work however lower case not working.
Before opening the laptop - all the keys worked as they should without problems.
See attached photo of the cable I am referring to.
Cheers and best regards
PS I wish I had just bought headphone instead of opening it to replace the speakers now!
