Program Compustar Remote, Unlock All Doors

I just purchased a new truck and it has a compustar remote start. I can’t get the remote to unlock all doors instead of driver door, what do I need to do? I added a dronemobile to it because the antenna was taken out. Is there something I change on module or in the programming of remote?

We would need more info to assist you. What Year, Make and Model of truck? What Model Compustar system? What bypass module ( if any )? Depending on the vehicle and the bypass model used, it might be possible to set the Compustar or the bypass module to "double pulse Unlock output" and get all the doors to unlock but... Changing the Compustar programming options requires either the remotes or an OP-500 programmer. It's not a simple switch setting. Don't think you can do it with DromeMobile, either. That being said, you can get a 4 button Remote Kit that includes the antenna, antenna harness and two 4 Button remotes for $30 off eBay. Search on "RF-1WG15-AM"Soldering is fun!
