Default Automatic Windows Issue

I'm currently own 95 LS 400, the previous owner lost the remote key so I'm stuck with the valet key.

the issue is when i turn the driver side key to 'unlock' and hold it, only driver side window slides down.

is that normal? or all windows including sunroof should open as well?

all of them, with an ordinary key, never tried it with a valet key, could be designed that way (my thinking)..
95 has no "chip", lockout, go get a regular key.

Possibly related ...

I have a '91, and have disabled the alarm system by grounding the green wire in the driver's footwell. By doing that, the feature that allows all 4 doors to unlock with the key in the driver's door key cylinder (by turning a second time) is also disabled. No idea why, but it is confirmed. If I undo the alarm-disabling-ground wire, that feature comes back.

I doubt the valet vs. regular key has any effect on your problem.

Also, my '91 never had the windows-down feature.

on 95-97 only the D/S window does this with the key. On 98-00, they made this standard on all 4 windows.

I see, is it possible to program it to open all of the windows?
I saw on youtube that all of the windows slides down with oem remote by holding the unlock button (its toyota celsior). i can't see whether its 95-97 or 98-20 since he/she recorded from behind. Here's the video:

Its not possible. The 98-00 have a totally different body control module that controls the windows, even the harnesses are somewhat different between the UCF20 and UCF21 LS400s.

That car in the video is a 98+ you can tell by the center headrest on the rear seat.

thanks a lot for your answers. apparently 95-97 can only slide down the D/S window.
