What type of key pad does it have? Email me a picture of the keypad. Email address is my signature. Not sure if I can help as I have never seen a WP with keypad but I will try. There should be a way to by pass it like the Info Link modules.

If it has a drive/tow switch, make sure it's not on or the plug disconnected.
