The key is locked in the car. Tell me about it.

The car keys are locked in the car. The unlocking method is as follows:

1, take the spare key to open it. Although it is simple, some people really forget it. Mainly driving with a master key every day. The spare key is always in the corner of the house. When I am in a hurry, I will forget that I have a spare key.

2, 4S shop rescue, if you don't have a spare key, call 4S shop first to rescue, 4S shop has many ways to unlock, you can use a special computer (if the connector can be plugged in), you can connect the door opening line, you can also hook it with wire. However, because unlocking can't make much money, many 4S stores are reluctant to unlock, which wastes a long time and manpower. It is better to earn more by doing maintenance in the store, and you may find reasons to shirk it and tell you that you can't go or don't open it.

3. Find an unlocking company. If the 4S shop doesn't work, you can only find the lock company. Professional car unlocking company technology is still very good. You can unlock the lock in a few minutes without destroying the lock core, and the charges are different.

4. If you are in a remote place, or where the unlocking company can't go, you can only smash the glass. Don't smash the glass. It is best not to smash the small triangle glass or the left front door glass. If you smash the small triangle glass, some triangle glasses are not cheaper than the big glass. More importantly, many 4S stores don't stock it, because few people replace this kind of glass. Once it is in stock, it will become a backlog. If you break the left front door glass, it will be enough for you to drive, especially in winter.
