Stuck#3 key in laptop keyboard

[Roy]

Hello group
Recently I noticed that when I open one of my sony notebook s, I
notice that there is something thats blocking the particular letter
key from being pressed to produce a letter on the document I am
preparing. It’s some sort of a tiny movable obstruction something like
1-2mm in
diameter.I am not sure where it came from.
I would like to remove it but am not sure if such notebook
keys can be pried open like the desktop keyboard.
Or do I really have to carefully detach the whole keyboard and remove
the obstruction?
This unit is one of the 17 inch VAIO AR series.
To keep that keyboard usable I have to poke the area where the
obstruction is occuring allowing to roll aside, but that is not a
permanent solution.
Now I am pressing that obstructed #3 key sideways so that it will work
as if I press is frontally it won’t.
I would like to hear what are the suggestions of people that have
similar experience or knowledgeable in removing notebook keyboard
obstruction.
TIA
Roy

I wonder if this obstruction is  a broken off part on the
keyboard or if it's something from the outside world that
become lodged in there.  If a broken off part, that could be
why the key doesn't work so well, but if it's something from
outside the laptop then however it got in is in theory a gap
big enough to get it out again.

Some keyboards can't be taken apart, they're non-servicable.
You might as well pull the keyboard module out and examine
it to see if this is the case.  Gently prying up on it or
flexing it might help, (once it's out of the laptop) but I
can't assure you that it wouldn't break.  Same goes for
trying to pry that key off to gain access to the area.

A last resort might be running water over the removed
keyboard module.  If you're lucky and it's a food particle
that may dissolve it, though you'd then need to shake excess
water out and let it air dry for a relatively long time as
the construction of it may trap water inside such that it
drys very slowly (multiple days dry time).- Hide quoted text -

I was also thinking about that possibility about broken part as I
meticulously keep my laptop to prevent any undue ingress of foreign
matter. Its not my habit of doing some dining while using my notebook
either.
I am reluctant to pry it often as I am far from the Sony service
center ( I am travelling overseas ) if something wrong went with my
DIY repair. I am somewhat clumsy tinkering with delicate things...
So my last resort if for a competent laptop repair specialist to sort
out this problem but have no idea what would be the ball park figure
for such dissection...in USD?
Thanks
