Mercury 1996 Sable Manual page 168

If the key has been coded, the anti-theft
indicator will come on for two seconds. The key
can then be used to start the vehicle. Repeat
until all spare keys have been coded.
If the key coding failed, the anti-theft indicator
will flash and the vehicle cannot be started with
the new key. Coding failure can be caused by
the following:
The new key was not inserted within 15
seconds, or
16 keys have already been programmed, or
The key does not have an electronic code.
Try the coding procedure again. If it fails again,
see your dealer or a qualified technician.
Windows
Using the Power Windows
Each door has a power control that opens and
closes the window on that door. The driver's
door has a master control panel that operates all
four windows.
The power windows only operate when the
ignition key is in the ON or ACC position or
when the ignition has been turned from the ON
to the OFF position and/or the key has been
removed and no front doors on the vehicle have
been opened.
The power window controls are illuminated.
Do not let children play with the
power windows. They may seriously
hurt themselves.
