Scytek A10

I need help with my wife's Scytek A10 that was installed from the dealer on her 2007 Nissan Sentra. It has a 2 button remote. When you would lock the doors, the siren would chirp. LED light would flash advising its armed. Now all she has is the ability to unlock her doors but the alarm will not arm. LED is solid red. Fuses on the alarm are good. I can enter into the programming mode by turning on the ignition and pressing the valet button 5 times. It makes a long chirping sound. But I cannot figure out for the life of me how to reset the alarm to factory default. In the manual it says to press transmitter button 3 but the thing only has 2 buttons. From the sound of what this alarm is doing, can you give me a clue as to what is wrong?

Sounds like you are in Valet Mode.  Try this procedure to exit Valet Mode:

Valet Mode

 

The Valet Mode temporarily disables the security system so the vehicle may be operated by a mechanic or parking attendant.

To activate or deactivate the Valet Mode:

1. Turn on the ignition.

2. Press and hold the override switch for 5 seconds.

    · The siren will chirp once and the LED light will stay ON to confirm the Valet Mode is on.

    · The siren will chirp twice and the LED light will turn OFF to confirm the Valet Mode is off.

3. Turn off the ignition.

 

While in Valet Mode the remote transmitters will continue to lock and unlock the doors, and operate the optional auxiliary functions
