What to Do When the Car Has No Power and the Key Won't Open the Door?
2 Answers
There are two solutions when the car has no power and the key won't open the door: 1. Call a professional from a 4S shop to unlock the door: Alternatively, you can also contact a locksmith company to unlock the door. It is best not to force entry into the car by breaking the glass, as this may damage the vehicle. 2. Normally, the mechanical key can unlock the door: If the car has no power and the spare mechanical key also fails to open the door, it indicates that the door lock cylinder is damaged. To avoid the situation where the car has no power and the key won't open the door, here are some suggestions: 1. It is recommended to occasionally use the mechanical key to unlock the door: If the mechanical keyhole of the door is not used frequently, it is prone to rust. Once the keyhole is rusted, the mechanical key cannot unlock the door. During car maintenance, you can apply some lubricant to the keyhole. 2. It is advised not to leave the car parked for long periods without use: This can easily lead to a dead battery. A dead battery will cause many systems in the car to malfunction. The performance of the battery will decline as the number of charge and discharge cycles increases.
Last time my car battery suddenly died, pressing the key fob did nothing, and I couldn't open the door – it was really frustrating. I immediately remembered there's a hidden mechanical key slot in the trunk. Using the physical key, I twisted it and got the door open. If your key doesn't have a mechanical part, don't panic, buddy. Try locating the 12V charging point under the car or wheel arch, then use a portable power bank or get a jump start from a kind stranger's car – power can be restored in about ten minutes. This has happened to me several times. Always remember to turn off lights and power-consuming devices after parking to avoid draining the battery. It's best to keep a portable charger in your car for emergencies. Get your battery health checked regularly at the shop – they typically need replacement every two to three years, otherwise winter breakdowns become likely. If you really can't handle it, call roadside assistance with your phone and have it towed to a repair shop for circuit inspection. Don't tinker recklessly and risk sparking or frying the chips.
