Car Alarms: volvo 740 security alarm, valet mode, volvo 740

Question
While cleaning the battery cables on my 1989 volvo 740 station wagon, I removed the positive cable and when I replaced it, the security alarm went off and I have not been able to quiet it other than removing the battery cable again.  What must I do?

Answer
Right, 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/override
button, found under the dash area, usually to the left
of the leg, drilled into a plastic panel.
Might even be part of an on glass antenna
in the windshield if it's a remote starter,
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 opposite direction,
key off.)

This should reset the alarm and allow you to
go on your way.

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

That should do it.

Good luck.
