Help all power locks dont work with fob

hey members in need of some help. I have a 2005 rsx. I noticed the hatch locked stopped working. Thought it was the actuator but then the passenger lock followed and then about a month later the driver did as well. I doubt all three actuator went out in small amount of time. The locks all work if i lift them manually. They do not respond to the keyless fob or the lock/ unlock lever on the driver door. When i lock all doors i am able to put the alarm on.
I have a hunch it might be the keyless entry receiver from what ive researched. I appreciate any input. Thanks in advance
Alex
