Car Alarms: 95 Camry Alarm with TDS Remote, valet mode, valet service

Question
I recently got my car repaired from a mechanic and since then the Alarm System is not working. The remote works for locking and unlocking the car but the parking lights don't flash when the car is locked and unlocked. The alarm also wouldn't go on when I open the car with my key (earlier locked with remote). The LED on the Dash is permanently ON.

Appreciate your help.

Answer
Sounds as if it's in Valet / 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,
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.

Thant should restor it to usable
service.

Have a good day.
