By activating a dormant software lock on their newest iPhones, Apple is effectively announcing a drastic new policy: only Apple batteries can go in iPhones, and only they can install them.
If you replace the battery in the newest iPhones, a message indicating you need to service your battery appears in Settings > Battery, next to Battery Health. The "Service" message is normally an indication that the battery is degraded and needs to be replaced. The message still shows up when you put in a brand new battery, however. Here's the bigger problem: our lab tests confirmed that even when you swap in a genuine Apple battery, the phone will still display the "Service" message.
It's not a bug; it's a feature Apple wants. Unless an Apple Genius or an Apple Authorized Service Provider authenticates a battery to the phone, that phone will never show its battery health and always report a vague, ominous problem.

Thanks for asking, fliptop. I actually DID remove and keep the sensors from those old alloy rims.
So, I called the wholesale club (that does free seasonal swaps) where I buy tires to ask about installing used sensors. It’s $13.98 a tire. I’d seen the $200 figure for new sensors advertised on the placard in the shop, and assumed wrongly that they don’t offer the service for sensors bought elsewhere.
Still undecided because I’m a cheapskate.
