Car Alarms: Disable Prestige anti theft system, valet mode, toyota camry

Question
I just now bought a second hand Toyota camry, didn't knew that it has a anti theft system. Until I used a jumper to charge the discharge battery to start my car, now different kind of sound has started and lights blinking when I try to start my car.The car gets started but the noise is not stopping until I take off the keys and lock the car.I don't have the remote , can you please help me in disabling the alarm.
Thanks !!

Answer
To start, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no alarm at all.

Let me know how it goes.
