Exterior door lock failure

If you are talking about the one with the keypad & remote, it was standard for a while but isn't anymore.  I didn't have one on mine, others that had it will need to chime in.

The deadbolt cylinder on my 2015 177 disintegrated while I was unlocking to leaving on a weekday trip.  It could not be saved - couldn't even get the key into the lock. I had to drill the cylinder to get the door open. The good news is the local RV dealer (Arrow Trailer Supply, Ontario CA.) Had several in stock. Price tag was $34. Works as original since it was an exact replacement.
  Thank goodness I was in my driveway when it broke. This would NOT have been amusing in a remote campground!
  The dealer ordered a warranty replacement a month ago but I haven't received it yet. I will be traveling with my cordless drill and suitable drill bits as a result of the experience..

Second trip out this week and the deadbolt failed and locked us out. Had to call out a locksmith at about $140.00.  We could go back to the dealer and fight for a replacement but at this point have no faith in a lock you can buy on Amazon for something like $30.  Thinking of trying the digital lock, does anyone have any experience with one?  Thanks!

Sounds like you have it all locked up.

I just got off the phone with Brandon at Fastec.  Two replacement cores, an extractor key, and duplicate keys are on the way.  He estimates that it should take about two weeks for shipment.  To this point, it seems like pretty decent service.    This vid illustrates the replacement process: https://www.youtube.com/watch?v=HM26DIjIP_g&feature=youtu.be
