I understand shutting down the car is a two stage process. You must lock the car twice, to obtain the maximum level of shutdown. Much like the European residential door locks of "double turn".

No need for any waiting... Double Lock in the UK locks the doors so the inside occupants cannot open any door. Illegal in the USA and most of the world.
Open the windows, do the 'double lock' press, then open the doors using the inside handles. If openable, NOT double locked. The extra beep just means the doors were ALREADY locked.

So the question still remains, does locking the doors impact battery drain?

Yes. Locking the doors shuts off Convenience Mode, which would otherwise stay on for around 20 minutes.
Convenience Mode is the state the car goes into when you unlock it or after you've stopped the engine - it's different from the ignition-on state you get by pressing the start button without your foot on the brake. The ignition is off, but a lot of the ancillary systems are powered up so you can do things like move the seats, listen to music, etc. Convenience mode ends when you lock the car; if you don't, it will eventually power everything down, but that takes up to half an hour while draining the battery since the engine is off and the alternator isn't running to charge the battery.

Great, Stuart. Guess I missed that when I got the car. Thanks for clarifying!
I’ll throw in my two cents so you guys can tell me I’m doing it wrong.
I leave the car in the garage, unlocked, and lately top down. I get in and out a lot without starting it, usually to open the hood, which fires up the HU Jaguar logo and the little annoyingly loud fan. (I know, that’s much later)
After reading recent replies here, I went and locked it last night. Which turns on a little blinky red light on the dash.
But alas, I’ll probably get in and out of it several times today, so it will stay unlocked.
Throwing caution to the wind!

Leaving the top down will cause permanent creases in the fabric and leave the interior vulnerable to all sorts of bugs and pests - spiders, moths, chipmunks, and worse.
Just imagine what this little guy (and his mama) could have done if my garage door was open. Taken by my Ring Floodlight Cam mounted under the roof of my garage.
but if locked via fob doesn't that initiate the alarm system which must be using some power?

Good point. The break even point between power taken during a 20-30 minute shutdown vs the power drain of the alarm, would determine which strategy is best for your individual situation.

As I have previously stated, my alarm is active even WITHOUT locking the doors.

@Cee Jay I now recall you said that, and scrolled back to reread your post. Does that only happen with the passenger door, or even with the driver door if you don’t have your key? Does it happen both top up and down?
I often go to the garage and open the driver door without the key nearby. Never tried the passenger door, as it’s next to the wall.

Yes the damn wall. The bane of every DIYer’s existence.
In the past, I have always locked my doors every time when pulling into my garage. However........Because of the oppressive engine heat the XK is giving off especially in the summer, I open my hood to slow down the cooking of the vulnerable plastics. My choice, the health of the cooling system or the battery. Naturally, I can't lock the car with the hood open, but I do automatically connect to my CTEK regardless if I'm pulling out the next morning. I'm OCD about keeping my battery fully charged at the same time trying to extend the life of the cooling system's plastics.
