Car Alarms: car alarm problems, valet mode, toyota 4runner

Question
I own a 1999 Toyota 4Runner Limited.  I had to change the battery in the remote and now it won't work at all.  Is there any way to test the battery or to reset the alarm?

Answer
Seems the system is reset, and needs
to be done again.

Probably when, or if it lost power.

Right, Ok, try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, press and hold in the valet/override
button, found under the dash area, usually to the left
of the leg, drilled into a plastic panel.
Might even be part of an on glass antenna
in the windshield if it's a remote starter,
until the installed LED (the blinking light)
in your dash area goes off, and the siren chirps twice.
(Your valet switch might be the toggle (on/off) type.
in this case, key on, flip switch in opposite direction,
key off.)

This should reset the alarm and allow you to
go on your way.

Just Repeat these steps to place it
back to valet mode.

That should do it.

Good luck.
