What are the reasons for no response when starting the Howo key?

If there is no response during ignition, it may be due to a dead battery or a damaged starter. The following is an introduction to Howo: 1. Vehicle Introduction: Basic configuration of Howo, 375 horsepower, EGR National III engine, bunk air conditioning, HW15710 transmission, ZF8098 imported steering gear, AC16 axle, HF9-ton front axle, 1200 tires, cargo box size: 8200*2300*1000, designed and produced for mining-type structures. 2. Correct use of Howo differential lock: The inter-wheel differential lock on the rear drive axle allows the left and right wheels to automatically differentiate when the car turns, thereby avoiding tire wear and mechanical damage. When the car slips on smooth or muddy road surfaces with one-sided wheels and cannot move out, engage the differential lock. At this time, the left and right half shafts become a rigidly connected shaft, and the car will naturally move out of the faulty road surface.
Last time I drove a HOWO truck, the key wouldn't start the engine and I was really anxious. There could be several reasons, like the key battery being dead—smart keys rely on battery power to transmit signals, and when the battery runs out, it stops working. Try simply replacing the coin battery. Or the car battery might be dead, especially in cold weather when it's prone to losing charge. If the dashboard doesn't light up, that's likely the issue. Sometimes the anti-theft system acts up, interfering with signal reception. I started panicking, but a friend suggested trying manual unlocking first—use a spare key or the mechanical slot to start the car. That time, the issue turned out to be a stuck starter motor, and I had to spend some money to replace it. It's a good idea to regularly check the battery life and key condition during maintenance. Avoid forcing the key to turn to prevent damaging more components. If all else fails, call for roadside assistance—safety first.
As a car enthusiast, I've researched HOWO starting issues. When the key ignition doesn't respond, it's mostly signal chain failure: the key's RFID chip may be aging or the button has poor contact, causing signal transmission failure; if the vehicle's receiver module gets damp or damaged, it can't recognize signals. More serious is the starting circuit problem - blown fuses or burned-out starter relays will cut off the circuit. I've measured battery voltage with a multimeter - if it's below 12V, just replace the battery; if the horn sounds but the engine won't start, it might be a relay issue. Don't overlook loose circuit connections - I've fixed issues just by cleaning dust. Have a professional shop check the ECU and anti-theft system to avoid bigger troubles. Regular maintenance of keys and batteries is crucial.
