clifford 770 remote not working sometimes

I have a Clifford 770 installed in my Honda civic. Recently the remote stopped working sometimes. I have replaced the battery twice and still nothing. Neither remote seems to work. It will be like this for a couple days and then magically the remote will work a few times. It's getting very annoying to have to open the car with the alarm going off then enter my code to stop it. Please any help.

Are you parking near any industrial radio transmitters? Police, emergency responders? Otherwise check your antenna connections at the antenna and the brain end. Replace the batteries in both remotes, erase them from alarm memory then re-pair them with the alarm.

I will have to try that. I don't park next to any type of the things you described. It's just weird. It will not work for a few days to a week or so and then it will just work fine sometimes. I also noticed that the proximity sensor does not work all the time. I bought the car with the alarm on it, and it was fine for over a year and then one day it started doing it.
