Avital remote start programming

I I have a 2011 Ford Fusion with an avatar remote start that was installed professionally about 3 years ago. I replaced the battery in the remote start does not work when I hit the button on this remote start remote the carsdash lights go on like normal but no start. Any help does i t with one remote. Other remote doesnt work altogether.

Just played around with it one remote works fine when the key is in the ignition starts up without it nothing... I don't know the model its a one button remote.

If I understand you correctly it remote starts when the key is in the ignition. If this is the case, it sounds like you have a problem with your immobilizer bypass. This is the black box that simulates a key in the ignition so the vehicle will start. Maybe a pinched/loose wire, etc. If you're still in the area, why not take it back to the place that installed it?

My ex once told me I have a perfect face for radio.

It happened right after i replaced the battery of the car. So i figured it had to be a programming issue. I checked the wiring all is tight any way i can test to see if its a bad bypass? I work nights and crazy hours ao i figured id try myself before bringing it back to the place thats an hour away

If you want to check the bypass, you need to make sure it's got what it needs: power, ground, ignition, etc. Pull out your multimeter and start testing wires at the bypass plug. If it's got all the right inputs and no output, then it's bad. If you are not getting the trigger signal from the Avital to the bypass, then there's a problem with the Avital.

I don't have any experience with Avital, so I can only offer general guidance.
