I have BE469s and they do work with Hubitat (mine work quite well in fact).
Mine are currently the BE469ZP version (Z-Wave plus, 500 series chipset), but I used to also use the older non-plus BE469NX version.
BUT, getting them to work is all in the initial pairing. I don't think they support Network Wide Inclusion (NWI) (at least the BE469NX does not) so you have to bring the hub and lock close together when pairing.
When pairing, I found you get the best results if you install the lock where you plan to use it, and then bring the Hub to the Lock (in my case, using a long Ethernet cable so the hub can be next to the lock). Some say to bring the lock to the hub when pairing, but I found that it works better the other way around (bring the hub to the lock). I think its because if you pair where the lock is to be used, the lock better learns its neighbors.
Then, after you pair everything, have the hub do a manual "Repair Z-Wave" from the Z-Wave Details page. Now, there are many who will tell you this isn't necessary, but if you are using the "older" 469NX which isn't "Z-Wave Plus", it needs to learn routes back to the hub, and in my experience, the "Z-Wave Repair" is needed if you have the non-plus devices.
Finally, as mentioned, I changed all mine out for the "ZP" versions. I was able to buy a number of used locks on ebay for about $20-40 with shipping. It doesn't matter which "finish" you find on ebay (Bronze, brass, nickle, etc)- you can swap out the internal mechanism and put it into your lock with just a few screws. That also helped.
So, if you haven't considered the foregoing, maybe it will save you a bit instead of replacing.
Or, as you say, just buy new locks if you have the extra $ to spare.
