Experts. I disconnected the battery last night and lost all alarm fuctions. Does somebody know the programming instructions for the 457GW so I can reprogram this and my alarm. Please advise ASAP. Thanks

The only "programming" the 457G requires is passlock learning, and that is done everytime you start the vehicle with a key automatically.
When you say you lost all functions, what is not working? Is the alarm responding to the transmitters?

I have the clifford 3.5. When I push any key on the remote is beeps for no signal or antenna. I have already checked the connections and tried reprogramming the alarm, but it will not program. And I am thinking it will not program because is doesn't see the door trigger. So that is why I want to look and the GM 457 module.

I have seen some DEI pieces in GM's that lock up when the battery is being reconnected, they do not like the surges from the side post terminal being reinserted. Try just disconnecting the fuses to the system and reconnecting, this may clear up your issue.

I disconnected the antenna connector from the alarm module and plugged it back in and all works well now. It must have been locked up. THANKS for the help. You guys are the ISH.
