How to open a locked car door lock without a key

There are many different ways to unlock a locked car without a key will be introduced in this article! The first method is that you can use the Lishi Lock Pick, which is a specific locksmith tool to unlock you car. And except for this, we also list some other ways for you in the following.
 
Use String
Here’s a tip for the next time you have to send the dreaded “locked keys in car” text: Keep a roll of string around, and you’ll never have to cash out for a locksmith again. The video below shows you how to unlock a car door without your keys.
 
Just tie a slip knot in the string per the video’s instructions, creating a loop the size of your index finger at the end. Then, wiggle the string with the loop into the upper right corner of the driver’s window. Now, holding the string with both hands, move it gently in a back-and-forth motion (like you’re flossing a giant tooth). Doing so will shift the string further down the window and toward the inside lock.
 
This is where things can get tricky. Carefully maneuver the loop over the lock, pulling the ends of the string to tighten the loop at the same time. When you think you have a solid grip around the lock, gently pull up on it to unlock the car door. Voilà! You’re back in action — and back on the road.
 
Use a Long Rod
As long as you can pry the top part of your car door open at least a little bit, you can use a wooden wedge, air wedge, and a rod to unlock your car. Grab the wooden wedge first and slide it in through the top part of the door. To not damage the paint, put a cover (preferably plastic) around the wedge. Slide the air wedge in next to the wooden wedge and pump air into it to create more separation between the car and the door. Push in the wooden wedge the most you can until you have a sizable gap. Finally, slide the rod in through the door gap and carefully unlock your door via the locking mechanism on the side.
 
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. Never leave home without one of these items—or these other must-haves on our road trip essentials checklist.
 
Use Your Antenna
On older model cars with a specific style outer handle, like in the screenshot below, you can potentially unlock the door from the outside using nothing but the antenna from your car. Just unscrew the antenna, carefully maneuver it up through the inside of the door handle, and move it around until the lock starts jiggling. Once you see you're making a connection, push your antenna forward and the door will unlock.
 
These are the useful ways to help you unlock your car if you lost your key! Try all these methods and find which is suitable for you.
