ADT New door sensor does not pair

New ADT door/window sensor does not pair, I got it from ebay but without battery, I think I wrongly installed battery before scaned the code, I do not know if this is the case. Pairing process fail after some minutes and hub goes to “System Inactive” while pairing attemp, I Restarted the sensor many times to pair (blinking led) without results. I read I have to restart ADT hub but Im not sure of it, anyone can help me please?
