I work on banking equipment so I deal with locks every day.
For a different electronic lock I recommend these. They are very reliable

But make sure the wires are put in the correct spot or you kill the lock. Battery in the bat hole
If you wish to get dial lock know there are multiple grades. Consumer and higher quality, the cheaper ones are not well made
Good used ones can be had off of eBay. There are many dial locks that came off of ATMs that are available

With the videos on YouTube anyone can install one who can change their own oil and tires
Use lock tite (blue) on the screws that hold the lock to the door
Do not close and lock the door until you have locked and unlocked the door many times
Take photos of the inside of the door so if it ever needs to be drilled the photos help mitigate the number of holes needed
FYI the flat keypad. Ie membrane keypads have open edges that will wick water into the buttons and short and corrode the aluminum conductors in the keypad
I seal the edges with clear silicone rtv to make the keypad more waterproof. Put on the edge and wipe off with a paper towel leaving the edge covered
