2001 olds silhouette non functioning alarm

Disconnect the battery terminals and wait 5minutes reconnect them when the alarm sounds use your keyfob to turn it off you should be out of theft mode and functioning properly

red light blinking where ? Where is it located ? PATS - passive anti-theft system . You need to get it to a ford dealer

THE RED LIGHT ON THE DASH WILL BLINK OFF AND ON WHEN THE ALARM IS ENGAGED AND THE CAR IS LOCKED.

This is most likely your "Valet" alarm disable switch. Use to disable your car alarm so you can keep your Alarm Fob and let a Valet, mechanic, friend etc. operate the car without the alarm being functional. If it is an after market alarm, consult the mfg's manual, if OEM contact dealer for operating instructions.

Do you have an alarm system installed? These sound like the alarm indicator lights. They are supposed to deter theft and break ins.

I'm assuming its an original alarm or system that came from factory or dealer. When the light blinks is because the alarm is activated. Look underneath the radio the alarm brain might be there. There will be a label on it saying alarm or security system etc. Disconnect the harness to it and try operating your vehicle.

remove the battery from your remote and see if works

disconnect your battery for six Min's and re attach the post clips. this will reset the alarm board function. if the problem persist, the theft system is failing and will unfortunately have to be replaced or deactivated.
