Sounds like you may need to return it. I had a brand new one that did something similar then suddenly started working and has been working fine. My issue was that it was stuck open and the bolt did not close when I tried. Not sure what I dod. But I called support and they said to return it. Then it started working so I have kept it. Your issue sounds different and the spring may be gone or stuck.
