What is the reason for the continuous flashing of the keybatt indicator light?

The reason why the keybatt keeps flashing is that the battery in the key is low on power and should be replaced. 'Key' translates to 'key', and 'batt' translates to 'battery'. The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Indicator and warning lights: Timing belt indicator: Some imported cars that use timing belt drives and overhead camshafts generally have a limited service life for the engine timing belt (approximately 100,000 km), after which it must be replaced. To ensure timely replacement by maintenance personnel, a timing belt service life indicator 'T.BELT' is installed on the dashboard. Exhaust temperature warning light: Modern cars are equipped with a three-way catalytic converter on the exhaust pipe, which increases the exhaust temperature. However, excessively high exhaust temperatures can easily damage the three-way catalytic converter. Therefore, such vehicles are equipped with an exhaust temperature warning device. When the exhaust temperature warning light comes on, the driver should immediately reduce speed or stop the vehicle. Once the exhaust temperature drops, the warning light will automatically turn off (however, a fuse-type exhaust temperature warning light will remain on if not adjusted or repaired). If the exhaust temperature warning light does not turn off, the cause should be identified and the fault resolved before continuing to drive.
A constantly flashing key battery indicator usually signals low battery power, which is quite common. For instance, when I drove a Ford last time, the light kept flashing nonstop, and it turned out the key battery was nearly depleted. Replacing it with a new CR2032 battery restored normal function. Many mistakenly assume it's a car issue, but the battery is often the simple culprit. Most car key batteries last 1 to 2 years, and prolonged disuse drains them faster. Don’t delay replacement too long, or you might face unlock/start failures—quite annoying. The replacement process is straightforward: pry open the key casing, remove the old battery, clean the contacts, and insert the new one. It costs just a few bucks. Keeping the key dry to avoid moisture helps extend its lifespan. It’s wise to keep a spare battery in the car for emergencies on the road.
