[QUOTE=buffalolake;786393]I have been using this one since August of 2014.
RV Lockâ„¢
I have the model with the built in keypad. Price was a bit steep, but it is still one of my favorite trailer mods. I can use a key fob remote, or type in a code of my choosing to lock/unlock the door. I have a backup key in case the batteries die. On rainy days I can lock/unlock from the cab of my truck. Lock uses AA batteries, supposed to last about 6 months. The only complaint that I have had was that it barely covered the factory lock opening. Key FOB works great as well.
Ditto on RVLock. I have one with the remote keypad. Mounted it next to the door about 8-10" below entry knob so we can reach without climbing steps. I have the full body paint CC and there is a \small amount white that is nogt covered by the new handle. Have had to change batteries a few times over the last 2 yrs. They make a newer version that has keypad and handle all -in-one.
