Car Alarms: 92 chevy blazer car alarm, car stereo system, chevy blazer

Question
my son is trying to install a car stereo system in his car and the alarm system is going off and won't stop.  we called a mechanic who said to put the key in the door, but the car door key does not fit.  what now?

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.
