How do I reset my Python car alarm?
Usually all you have to do to reset the alarm is cycle the key through the ignition. But from what you're describing (with the LED on constantly) it sounds like it's in Valet mode. You can fix this one of two ways. Press Lock, Unlock, then Lock (one button at a time). Or if you know where your Valet switch is, turn the key to Run, turn it off, press the valet button once. This should do it. Oh, and btw, it's nice that you included a picture of the keyfab, but DEI uses that keyfab for a lot of their systems (I've got it myself and I have a remote start.) If you feel like digging around in your dashboard, the model number of your alarm should be written on the brain (big black box).
