I have the Bauer keyless lock and I'm mixed. It works well, but tends to default back to the factory code randomly.
Edit to add- I noticed that when the batteries are brand new it's no issue, it will work for a long time after the default starts happening so maybe once the batteries have a little use the voltage gets low enough that it defaults, but not so much it quits working. I have considered wiring in a direct feed from the house batteries.
Their customer service is great, my original had an issue, my dealer couldn't do anything with it so I called Bauer directly, they sent one second day air with a label to return the original. No fuss, no issue.
