What to Do When the Built-in Tire Pressure Monitoring System Runs Out of Battery?

When the built-in tire pressure monitoring system runs out of battery, it needs to be replaced entirely. The batteries used in built-in tire pressure monitors are generally non-rechargeable, so once they are depleted, the entire system is effectively dead and must be discarded. The tire pressure monitoring system (TPMS) works by recording the rotational speed of the tires or using electronic sensors installed inside the tires to automatically monitor various tire conditions in real-time, providing effective safety assurance while driving. There are two main types of tire pressure monitoring systems: indirect TPMS and direct TPMS. Additionally, there is a hybrid TPMS. As an active safety device, the tire pressure monitoring system can alert the driver promptly when signs of tire danger are detected, allowing them to take appropriate measures and thereby preventing serious accidents.
Last year, I also encountered the issue of a dead tire pressure monitoring sensor. The warning light on the dashboard kept flashing, which really had me on edge. The built-in sensors are inside the tires, and their batteries typically last five to six years before dying out—something you can't fix yourself. I went to a repair shop, and the technician said they had to remove the tire, replace the entire sensor, and perform a wheel balance, costing me over 300 yuan per tire. Looking back now, it was money well spent because incorrect tire pressure can easily lead to a blowout at high speeds, and safety is paramount. For daily driving, I regularly check the tire pressure manually with a gauge to avoid false alarms from the warning light. I recommend you get it replaced at a professional shop as soon as possible—don't risk an accident—and ask them about battery recycling while you're at it.
