Hi I have a auto page alarm and remote start. It worked fine but now the blue LED light just stays on it doesnt blink even if the alarm is armed or not. The alarm sound itsnt working when I lock or unlock it doesnt beep either. My remort start isnt working. And its killing my battery! Does anyone know why its doing this!

contact manufacturer-or local auto stereo stores most shops offer low cost replacement alarm systems

i have an autopage alarm system and i can't program my remote to it

The first problem is, you went to bestbuy. The second issue is the remote should not lose the pairing because the battery was removed. Your remote is probably defective.

If the led is solid blue when the key is out of the ignition that means your in valet mode. Which would disable the alarm, but not the starter.
Simply turn key to IGN position then back to OFF.Push the valet button which is on the antenna next to the led and the led should turn off.Close door on vehicle and lock vehicle.Siren should now chirp.
Cheers!!

Your alarm is in valet.Open the driver's door, press lock, unlock, lock. The blue light should go out and the chirps should sound when locking and unlocking now.

Your system is in valet. To take the system out of valet with remote: open any door, press lock, unlock, lock. Now check the LED; it should be off. Close the door and arm the system to check.
OR
Turn the key on then off. Within ten seconds press and release the valet switch. The LED should be off now. Close the door and arm the system. The alarm should chirp to confirm that it is armed.

disarm system get inside the car turn key to ON position with door OPEN push the black valet button one time turn key off
now your out of Valet mode
or

open your door hit ARM then DISARM then ARM and that should also remove Valet mode if you don't know where the valet button is at.

You need to adjust the tachometer sensing wire, it usually wraps around a spark plug wire so I can sense when the car starts. On my spy alarm, the wire was grey. Hope this helps.

the alarm is in valet mode .open a door press lock unlock lock on the remote and it should take it out of valet mode

this "could" be a bad ground, however, usually when these units lose ground, they activate the siren at a really low level, because they are trying to ground through the siren.

I would say to check where the antenna plugs into the main unit,(brain) but honestly, in 17 years of dealing with DEI alarms, 99.9% of these problems are due to the transmitter - it may blink the LED like it is supposed to, but that doesnt gaurantee it is sending a signal. I would recommend buying a new transmitter and programing it to the brain.
