Hello OwenP134,
I would recommend applying fine machine oil, or GT85 (or similar) PTFE lubricant to the latchbolt and deadbolt slots, operate a few times to work lubricant into the components.
The lock is reversible, the details for doing so can be found in the instructions under the specifications tab.
Thank you for using Q&A
