Car Alarms: automate553, valet mode, dash area

Question
I have a auto mate 553 in my 2002 explorer.  All of a sudden it stopped unlocking the doors and when i open door manually the horn goes off until i put the key in ignition.  The valet swith is just a button underneath wheel.  Any suggestions?  Thank you.

Answer
Should be no problem really.
It appears from your expaination, that the
car alarm is in service mode.

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 hidden away spot,
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.

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

That should do it.
