80q alarm problem

[Tom Love]

I replaced the drivers door handle and lock today and now there is a problem. I went to start it and the ignition was dead and the alarm went off. I cycled the key in the door and it shut off. Open the door and it goes off again. so on and so on so I remove the #19 fuse to disable the thing but I lose the central locking. Is there a better way to disable the antitheft system? Any ideas what is causing the problem? TIA for any help.
