Car Alarms: Is it broken, valet mode, dash area

Question
My car alarm keeps going off when I lock it. I just changed the battery. Do I need a new remote or do i just need to reprogram it?

Answer
Seems the system is reset, and needs
to be done again. Probably when 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/overide
button, found under the dash area, usually to the left
of the leg, drilled into a plactic panel,
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 oposite 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.
