Review on 🔐 Rungao Keyless Entry Door Lock Handle for RV Caravan Trailer Car Camper - Secure and Convenient by Sadik Pinger

This thing sucks. Will not program. Do not expect customer service from either the seller or Revain. I tried to send it back and was told to chop up the salt. Your money is gone. The battery for the key ring must also be sent in. It could be CR2032. But no. You'll have to contact the batter company to get a battery smaller than AAA. I tried to give this one zero stars but it won't let me. RUN FROM THIS ARTICLE.
