How to open car door without key

Method 1: Use a string

You can unlock your car door without a key by using a lanyard to pull the lock.

  • Take a rope and shorten it to at least three feet. It's better to have more time, like two or three, to allow for this.
  • Tie and knot with a bow the size of your index finger.
  • Try to open the door with a screwdriver and carefully insert the cable. We try to put the cord on the car diagonally, with the loop in the middle.
  • Move the leash back and forth until the cord loop secures the buckle. You must tighten the loop when maneuvering.
  • Now that the string circle is attached to the fuse, pull it up and you're done.

Method 2: Keyless with mobile apps

Be sure to register your car with the dealer after purchase. You will link your account to the registered vehicle for security reasons.

Note that some apps differ in features, but most new models have app unlock innovation. For example, the Toyota Car app lets you lock and unlock.

Other more advanced applications allow users to immobilize stolen cars, create vehicle health reports and turn the engine on or off. Other more complicated models use sophisticated locking technology, like the Hyundai i10 car.

OThe car has an automatic lock functionSo disabling it by holding the lock button for 5 seconds saves you the hassle of getting your keys locked in your car.

Here are some apps for different car manufacturers

  • BlueLink App - This app is for Hyundai. Open the app and you will see the unlock button. Tap to deploy the pin and you're all set.
  • myChevrolet app - This app is not just limited to lock and unlock. You can also use it to start, stop and even honk your car. You can also use this if your car manufacturer is GM.

  • HondaLink - This app works like the other apps and allows your Amazon packages to be shipped to your car.

Method 3: With a screwdriver

The screwdriver is a staple when unlocking a locked car door.

  • Find the car unlock button.
  • Carefully insert the screwdriver between the door and the lock. With a screwdriver and older car models, you can easily reach and pull the lock knob. If not, proceed to the next step.
  • There is now a small gap between the door and the frame. Insert the hanger or hooked rod to reach the latch and pull.
  • Carefully remove the hanger or rod from the car, followed by the screwdriver. You must follow this order to avoid damage.

Method 4: Use a tennis ball and a drill/screwdriver

Without tools, the tennis ball can be of great use if you have the skills. The tennis ball technique is a hotly debated method of unlocking your car. However, some claim it worked, while others need more practice.

  • Drill a hole in the tennis ball with a drill or screwdriver.
  • Place the tennis ball hole on the front of the key. We will try to pull the disks into the keyhole using tennis ball pressure.
  • Pump the tennis ball repeatedly until you hear a slight click.

Method 5: Call someone

If the above hacks don't work,Calling someone might be your last resort. First, check if there are local locksmiths nearby.

If not, some locksmiths specialize in how to get into a locked car, like Pop-a-lock. They would examine your vehicle lock and make the key in less than 10 minutes. It would also be better if you know the lock type to help them make the key faster.

Be prepared to spend $4 to $10 on older car models for your service. However, prices for luxury models between $250 and $450 can skyrocket.This guide tells you how much you will be charged for this Pop-a-Lock service.

If you don't want to pay the bill and you're wondering, "Who do I call for free?" call 911 to alert the police or fire department.

Calling them is extremely helpful, especially in an emergency when there's a child or pet trapped in the car. However, in some extreme emergencies, they can break your car window if the break-in tool cannot handle the situation quickly.

Other methods you can try:

    • Open your car lock with a hair clip
