Alarm going off |Windows central locking not working 1997 mercedes e320

Question by jonathanc.dickson posted 6 months 2 weeks ago in E-Class

I replaced the battery in my car after it had been sitting for quite some time. Before the battery was replaced my windows would not go down, sunroof would not work and central locking system not working. After replacing the battery now I can't get the alarm to stop going off when starting the car. the car will run with the alarm going off. Any suggestions on what the problem could be.
