Hi i need help So i have a vintage laptop and i really want to use the keyboard. then i found this guy that made his old laptop keyboard and he made it work whit usb whit a tensey. and then i tought can i do that and if i can how can i do it. my keyboard inside have the to transparent cabels and the matrix is also transparent and it is like paper. is there a way still to do it?

It is certainly possible, it depends on how much work you are prepared to put into the project.

If the aim here is to make the existing keyboard drive a current gen computer via USB then:

The photos suggest the keyboard is a matrix wired thing
https://en.wikipedia.org/wiki/Keyboard_matrix_circuit
that would be interface with the matrix library
https://www.pjrc.com/teensy/td_libs_Keypad.html

And the outputs of that fed into
https://www.pjrc.com/teensy/td_keyboard.html

So all the parts are there but quite a lot of assembly required to finish things up. Depends a great deal on how much electronics stuff you have done before. Suggested starting points would be:
Look at the old keyboard and try to trace at least a couple of keys to where they go into the circuit board
Using a multimeter confirm you can get a short circuit when the relevant key is pressed - it is possible there is corrosion on the touching surfaces from age and this whole project cannot work without a lot of repairs.
Download Arduino and the Teensyduino add on https://www.pjrc.com/teensy/td_download.html
under tools select board time teensy LC
look in files->examples->teensy->USB_keyboard and files->examples->keypad and see if you can see what you would be doing to graft the two together
Edit the keyboard example to include the keypad functions and confirm you can get it to compile

By this point you should have a good idea of what it would take to finish the project without having ordered any parts.
 
Metering where the transparent plastic PCBs terminates into the conventional PCB connectors is probably the easiest option, middle of your first photo but really pretty much anywhere you can get an electrical connection works.

It would also technically be possible to keep the control PCB and intercept the interface off there but would suggest not attempting that unless you've done reverse engineering interfaces before.
 
do you happen to know the name and model of the vintage laptop? looks like an ALPS keyboard. that company is not around but a Canadian company named Matias http://matias.ca/switches/click/
is selling some of the stuff that ALPS made back in the day.. i can't positively make out all the various
numbers on the keyboard sheet. maybe you could post them? it looks like the old membrane and rubber dome type as shown on this page, what you have are the membrane.
