It sounds like you may have a problem with the PSE pump under the rear seat. It supplies vacuum when activated by the switch to work your locks. Remove the rear seat to give it a visual and smell for a burnt aroma. The switch I believe was integrated into the vacuum element for the front doors. Someone please correct me if I am wrong.
I remember the alarm modules being behind the false floor on the passenger side under the dash. An easy way to see if you have a functioning alarm is to reach through an open window and unlock the car when the car is locked. Opening the door without deactivating the alarm with the key should set it off. The lock cylinder on the front doors will have an electrical lead for the alarm on/off. Good luck.
