Changed Battery and now I cannot remotely lock or unlock doors

What is your question?

Had the battery changed. Take out the old and replace with a new battery. Once done I have had problems locking and unlocking the doors remotely and some times the alarm goes off by itself. 2012 Toyota camry

What makes this problem better or worse?

when locking by hand using the buttons the alarm will go off.
