Morning Andy

Welcome
The suspension is self levelling, so if there is a leak somewhere the compressor will run when it senses power. If the suspension remains within ride height tolerance for a while after locking giving the car time to "go to sleep" shut down all systems bar the clock then it shouldn't run until the car is unlocked. Check the airbags for leaks with soapy water then work back through all the air connections to the compressor to find the leak.
With the key it may just need pairing again.

Happy New Year

Compressor running a bit after unlocking sound normal enough to me. If both keys are the same then it's probably not the key at fault and as said battery drain is a nightmare but the heater resistor can do this look for defrosting on windscreen as a sign it's on when it shouldn't be.

Look for threads covering the FSR = Final Stage Resistor (aka the Hedgehog). Part of the climate system just behind the dash besides the pedals. It’s a diy job, and yes as above if it fails it will keep the fans running and kill the battery. Not an expensive part.
