There are arrangements where you continue to pay for cars and houses without owning them. They're called leases and rental agreements. They typically cost a lot less for the consumer than outright purchases and at the conclusion of the lease/rental term the consumer is free to return the car/house to its owner without compensation for depreciation or wear & tear (though car leases usually impose mileage restrictions and routine maintenance requirements).
Rental cars and houses do exist, but you could still have fully owned cars and houses whose doors lock without paying a subscription. It doesn't have to be the full thing either. Certain tiers could disable only air conditioning for example.

For cars maybe, but not for houses. Property law for land is very old and very well established. If someone else is able to lock you out of your house then they are the title owner, not you. If you are the title owner then you’re well within your rights to have a locksmith replace the lock on the door.
This is happening right now with cars. Regular payments or some features on the car you bought outright stop working.
Mercedes restricts the performance of some cars if you don't pay $1200 a year for the “Acceleration Increase”. You have to pay more if you want to use the power you already paid for.
BMW offer heated seats for £10 a month. The car has heated seats that work fine, and you paid for the hardware already, but they are turned off if you don't pay more.
Neither of these are anything to do with ongoing costs to the company, like support or mobile connection, they just want ongoing revenue.
