Roewe 550 battery is dead, how to open the door? The mechanical key won't open either. What's the problem?

The solution to the dead battery of the car is as follows:

1, manual cart helps to start. When many people can cart, it is simple and saves money, but it is time-consuming and laborious.

2, take the wire to help start, in the case of other cars around, you can save time, effort and money. The old driver mentioned that when we buy a car, we usually send it to the fire line, suggesting that we put it in the trunk for emergency. If our car is in a residential area or underground garage, we can ask a car owner for help, so we can start it easily. In fact, the 4s shop is also for the sake of customers, which can be said to be very humanized.

3. Being driven away by someone else's vehicle. If the parallel line is fruitless and there are cars around, you can take the car away.

4. The mobile phone emergency charging treasure is started, and there is a car emergency charging treasure nearby, which saves time but costs money. If there is no fire line, you can prepare a car charging treasure. You may think it is similar to our mobile phone charging treasure as soon as you hear this name. Actually, it's not like this. Its current is very high, up to 654.38+100000 mA. It has a special wire to connect the current on the car, which can help the current work. Moreover, the price of car charging treasure is not very expensive. Generally, it can be bought for several hundred dollars, and we can prepare one at any time. When you buy, you must choose a well-known and guaranteed one, so the safety will be higher, because it is a current device after all. If the quality is inferior, it will not only guarantee safety, but also cause harm to the car.

If you don't have any friends to turn to for help, and you are not sure about it, it is safer to ask the 4S shop to rescue you, or ask the people in the nearby repair shop to use batteries to supply power. Just call them and ask them to bring the battery cable to pick you up! You can also remove the battery yourself, then go to the repair shop to charge it and put it back, and you can get a taxi.
