My RVLock (purchased in Dec. 2014) has recently stopped locking the rv when using the remote but will unlock it. A few weeks ago I discovered that the lock mechanism isn't locking when I input the code either with the touch pad or the remote fob. The mechanism does work to unlock if you lock it with a key. I have talked to RVLock and bought two new circuit boards. With the new touch pad board the lock works but the mechanism only travels half the distance each time you activate it. This means you have to activate it twice to get it to lock or unlock. Has anyone else had this problem? Any suggestions?
