I have the factory keyless entry or alarm or whatever it is but it is acting up. First thing is the chirping. Sometimes it chirps, sometimes it doesn't. Seems totally random when it stops or starts. Second thing is it seems to get "lost" sometimes. I get out and hit the button and it tries to unlock. Hit it again and it will lock. Or sometimes I will walk up and hit the button and it will lock again, rather than unlocking. I finally just stopped using it. Any suggestions? I miss the keyless entry as all of our other vehicles have it and it is a nice convenience.
