How to open the car door if the key is lost

If you want to drive, the first step must be to open the door with the key, and then start the car. If you lose the car key because of your carelessness, how to open the door?
 
Try a Coat Hanger
The coat hanger trick is a classic; you’ve probably seen it in a few movies. All you need is a coat hanger and pliers.
“Use the pliers to unravel the coat hanger so you have one side hooked and one that’s straight,” says Laura Gonzales, marketing manager at Audi Bellevue in Washington state. “You’re going to slide the coat hanger between the window and the weather stripping. Once the hook is below the window, you can start fishing around for the control arm. Once you find it, pull onto it and your door will open.”
 
Use a Strip of Plastic
If you have the locking mechanism up top instead of on the side, you can use a strip of plastic instead, which may be easier than a shoelace. You will still need to pry the door open somehow, with or without an air wedge.
 
Use a shoelace
Good news: If you own an older car with manual locks and you’re wearing shoes with shoelaces, you might not need to call roadside assistance. Just tie a slipknot in the middle of the shoelace, creating a loop the size of your index finger. Then wiggle the shoelace around the right corner of the driver’s side door until the slip knot is inside the door’s seam. Now, holding the shoelace with both hands, move it in a back-and-forth motion like you’re flossing a giant tooth. Doing so will shift the slip knot further down the window and toward the lock on the car door. Carefully maneuver the loop over the lock, then pull the ends of the string to tighten the loop. When you think you have a solid grip around the lock, gently pull up on it to unlock the car door. Ta-da! You’re in! You can also use a sturdy piece of string in lieu of a shoelace.
 
Calling for professional help
If you lock your keys in the car and need professional help, call emergency road assistance and ask if they will be able to open the door. If not, ask them to send a local locksmith. The good news is that each car key is coded by the auto manufacturer, and if you have the key code number and personal identification, a locksmith can make you a new key. Write down the key code number and leave it where someone at home can read it to you in an emergency.
 
Door locks are one of the important guarantees for home security. But now people lose their keys for various reasons, they can't get in when they get home, and they don't know how to open the door without the key. They want to ask the lock-picking company to unlock the lock, but they feel that the lock cylinder is wasted. In fact, as long as you prepare Lock Picking Tools yourself, you will not be afraid to face this situation.
