What to Do When the Anti-Theft Lock of a Great Wall Pickup Truck is Locked?

Check the fuses in the two fuse boxes located in the cab and engine compartment to see if any are blown. Verify whether the power supply to the anti-theft system is functioning normally. Since the negative wire of the vehicle's electronic control system is relatively thick, the possibility of a break in the middle is low. The main focus should be on checking whether the negative grounding wire of the engine's electronic control system is loose. With prolonged use of the car key, moisture may enter, causing the internal chip to malfunction. Try using a spare key to see if the vehicle can start. If the fault persists after the above checks, the most likely issue is a damaged anti-theft device, which can be resolved by replacing it with a new one.
I ran into this exact situation last week when my car suddenly went into anti-theft lockout mode while parked in the community, which nearly gave me a heart attack. First, I tried using the remote key fob to lock/unlock the doors, but got no response. Then I pulled out the spare mechanical key, inserted it into the driver's side door lock and gave it a firm twist, only to find it still didn't work. At this point, I started panicking more until I remembered my friend's warning about battery issues causing anti-theft system malfunctions. After popping the hood to inspect the battery, sure enough I found oxidized terminals. I used a wrench to remove the negative cable, waited five minutes, then reattached it tightly - finally the car came back to life. I'd suggest you try this power cycle reset before calling a tow truck. If it still doesn't work, contact a mechanic immediately. Final reminder: regularly checking your battery condition can save you lots of headaches.
