The solutions when the car is completely dead and the door cannot be opened are: 1. Take out the mechanical key, pry open the protective cover of the door handle on the left side of the car door, find the key slot, and use the mechanical key to open it; 2. If the door does not have a keyhole, seek help from a car 4S store or let a professional repairman solve the problem. The methods for maintaining the battery are: 1. Start the car regularly to charge the battery; 2. When the electrolyte is insufficient, add distilled water or a special replenishing fluid; 3. Frequently check whether the small holes on the battery cover are ventilated during daily driving; 4. Check whether the positive and negative terminals of the battery are oxidized; 5. Check whether any part of the circuit is aged or short-circuited; 6. Turn off electrical equipment when leaving the car.
I once encountered a situation where the remote key fob failed when the car was completely dead, and the doors were locked and couldn't be opened. The solution is to find the spare mechanical key—many remote keys hide a small physical key inside. Pull it out and insert it into the lock hole under the door handle, then gently turn to unlock. If you don’t carry a spare key, you can call for roadside assistance, as insurance companies or 4S shops often provide free unlocking tools. Remember not to force the door open yourself, as it can easily damage the paint or the door lock mechanism. For prevention, regularly check the battery's condition and replace it every two to three years. If the car is parked for a long time, start the engine to charge the battery for 10 minutes. These habits can help avoid trouble.
When a car is completely dead, it's common for the doors not to open. From a safety perspective, try using the spare key first. My habit is to keep the mechanical key in my wallet, so I can easily open the door if I forget. If there's no key, contact professional rescue services—they can open the door without damage using airbags or pry bars. Avoid risky DIY attempts to prevent vehicle damage or mishandling. Cars left outdoors for too long are prone to power leakage and depletion. Develop a habit of regular short drives to recharge the battery, and install a battery monitor if necessary for early warnings. These small daily practices can save you from major repair costs.
