Anyone have a problem like this. My girlfriend just bought a new house (built in 2005)about 3 months ago in a new development, anyways when I would stop over and get out of the z and lock it with the remote everything worked great. so last week I get out of the car and the remote is not working so i'm thinking the battery. So later that night I pull up in my drive way and do I reset with the remote and everything is good. Last night pull up in her drive way and same problem. Could it be a invisible fence that one the neighbors put in there yards? She just got direct, tv but I don't think that would cause interference?
