Exactly! My little Citroen C1 diesel stands for weeks at a time. When I want to use it I simply unlock, get in and start it up.

vaseline on the door seals stops a door iceing shut, Iām sure a lot a trampers carry Vaselineā¦
They would probably us it all by Friday 
only prob Iāve ever had was a knackered battery but apart from that itās been ok for a Ā£500 Clio.
the good thing about having a cheap run around that only moves @ weekends is the discount insurance you can get.

throw a set of jump leeds in the boot and if you have rear disc brakes park car in gear chock the wheels and leave handbrake off as pads can freeze onto the disc
+1. I always leave the car in gear with the handbrake off.
Like I say personally Iāve only had issues with ice, not brakes or flat batteryāsā¦and it was a particularly bad week for snow, must have been nearly a foot of iced snow on the car when I got back to it.
I guess really there isnāt a lot that can be done about that though.
Join the AA on its cheapest deal, always handy for when you get back late on Saturday evening and the place is deserted.
Leave the handbrake off and keep the key fob warm in the cab. If it doesnāt have a key fob, ā ā ā ā on the door lock to unfreeze it.

If you ā ā ā ā on your lock, it will unfreeze this time, but the water from your urine will stay in the lock and from then on, you will have to ā ā ā ā on your car everytime 
Not to mention corrosion problems 
The deicers to the lock usually will bring the same results.
Better idea is to go to the key cutter and cut a spare key to your car without bothering with immobiliser and stuff - just the metal key. It will cost pennies.
Then heat it, even with cigarette lighter, and use it to open the doors, even if you will have to repeat it a few times. By that method, you will not only not put any new water into the lock, but also likely you will get some of the water off, as the melted ice from the lock will then refreeze on the key making a thin film of ice.
The advice about handbrake is good, as in some models it frozes easily - I always leave my car on gear in winter - just the old habit from the times I was driving an FSO
If your car has alarm, disconnect it. It uses power, draining your battery, and, letās be honest, did anyone ever seen someone reacting to car alarm?
A pal of mine used to get a taxi, was cheaper for him than a car stood there for a week doing nowt.
Iāve got some ānight beforeā de icer from Halfords. It doesnāt prevent icing up but the ice which does form is soft and slushy

Could start another thread here. What sort of old banger ( car not wife ) do you use and how reliable is it.
Iāve had a succession of them over the years. Ford Capri - rubbish but fun. Maestro - absolute crap. About 3 metros - good value. Peugeot 106 diesil - invented by Satan. Astra - solid & reliable. Currently wrecking an avensis - itās been good so far.
Iāve just bought a 2001 X Skoda Octavia estate with a 1.8 petrol turbo under the bonnet. 150 BHP 
and great VW build quality. Averaging 38 mpg which isnt bad I reckon.
When I did it in the dim and distant past I used a taxi. No way was I going to leave my car on the bomb site that passed for a car park where I was working.
I think a lot of the problem is that when you drive in on Monday morning, the car doesnāt get thoroughly thawed out and dry, so you leave it all nicely warm and damp, ready to freeze solid.
Ive got an 850 T5, could do with a new battery though as at the end of the week it is slightly slower to start than normal but theres plenty of, lorries, tractors or forklifts to drag it round the yard to get it going and quite a few of the lads live in their trucks in the yard so always someone to help out.
I had a classic car and had a gizmo fitted to the battery terminal with a small red key which you could remove when leaving the car for long periods of time. Worked really well and is good as a immobiliser too! 
I think it was called battery saver?
As for iced up locks and doors, tepid water is perfect for this just a bucket of warm water will unstick most stuck doors or locks. Not too hot though as it may crack the glass!!
