What should I do if the car remote control key fails to start?

The manufacturer took this situation into consideration in the design:

1, open the door

There is usually a metal key piece on the remote key. Generally, there is a switch on the remote control key, and you can pull out the key piece by dialing it. This key piece can be directly inserted into the keyhole of the door, and the door can be opened and locked.

Step 2 start the car

Due to different brands, there are usually three ways to start the car when the remote control key fails.

(1) Stick the remote control key on the one-button start button and start it after a short pause (this method is suitable for most cars).

(2) Find the slot of the remote control key (often hidden in a certain part of the car, such as the armrest box, under the cushion of the water cup slot, etc.). ), insert the remote control key into this slot, stop for a while, and the car can start after sensing the key.

(3) Find the hidden mechanical keyhole (usually hidden behind the one-button start button and need to be removed), insert the key piece into the remote control key and start it like an ordinary car.

Finally, don't forget to replace the battery.

Precautions for using intelligent key.

1, don't put it with electronic equipment. Because intelligent key uses low-intensity radio waves, it may not work normally in the presence of magnetic field interference. Often putting smart car keys and mobile phones together will be disturbed by the frequency of mobile phones, and there will be failures. If intelligent key receives high-intensity radio waves, it may consume too much electricity. Therefore, don't put intelligent key near the TV or computer.

Don't throw it about. For intelligent key, the most feared thing is to fall to the ground from the sky, because the internal circuit of the key has weak impact resistance and is easy to be damaged in a serious collision.

3. The smart car key will burn out the internal circuit after entering the water, leading to failure. Once intelligent key is flooded, open the shell and lay it flat, dry it with a hair dryer, and then send it to the repair shop for inspection. Don't throw the key hard, because it is the easiest way to let the water flow to other important lines, and don't unlock it immediately with the remote control, because it may cause the circuit board to burn out.

4. intelligent key should not be exposed to high-temperature direct environment, such as dashboard or hood.

Don't leave the spare key in the car. Unlike ordinary mechanical keys, intelligent key won't lose the car keys, because it involves the anti-theft technology of the whole vehicle. Simply make one and you can continue to use it. It is understood that each manufacturer has formulated a strict keyless door opening and key matching process for its after-sales service department, so remind car owners to protect spare keys as much as possible.

6. Don't use the wrong battery. It is very prudent to replace the battery of the smart car key. Once something goes wrong, the circuit board in the key will burn out. Before replacement, the car should read the battery replacement diagram. When removing the key, pay attention to the original position of each part and try to choose the original battery. When installing, carefully distinguish the positive and negative poles of the battery, and do not put them in the wrong position; At the same time, pay attention to the sealing ring at the bottom of the key, and don't damage it when replacing it, otherwise it will burn out the circuit board.

7. Don't touch metal objects. When intelligent key comes into contact with or is covered by metal objects, intelligent key may not be able to work. In the process of bumping and jumping, too many falling objects on the key will wear the limit elements and contacts of the electrical switch through the lock core, which will lead to its relaxation and premature damage, and over time, the engine will not start or stall due to power failure.
