Car Alarms: Unable to unlock with remote, but see light blinking on remote, valet mode, toyota camry

Question
This morning i had a strange problem. I am not able to unlock my car with remote even though the LED light on on remote blinks when i try to unlock(so assume remote battery is fine). Now if i try to unlock the car with key and try to start the car Alarm starts buzzing as if the the car was still locked. It is expecting me to unlock the car with remote. So, either i want to disable the Alarm system or know why the keyless remote isn't working.
By the way, this is on '99 Toyota Camry, i think it is Custom installed Alarm. I bought this car in from a dealer.
All you help appreciated, thanks for your time.

Answer
Hmmm, might need to be evaluated by a tech to
trouble shoot the isse. Until then, to try to disarm it,
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. Once in Valet mode,
it will allow the car to start and operate
like there was no alarm at all.

The next step is if wanting to remove it,
you contact a local technician to
locate it, and affect neccesary service
for you.

That should solve the troubles.

Let me know what you discover.
