Method 1: Use a String

You can unlock car door without keyusing a string to pull the lock.

  • Get a rope and cut it to at least one meter. It is better to have it longer to around two or three for allowance.
  • Tie it and make a knot with a loop the size of the index finger.
  • Try to pry the door with a screwdriver and gently insert the string. We are trying to put the string diagonally into the car with the loop in the middle.
  • Move the line back and forth until the loop of the string hooks the lock. You should tighten the loop while maneuvering it.
  • Now that the circle of the string is attached to the safety, pull it upwards, and there you have it.

Method 2: Without key using mobile apps

Make sure that you register your car with the dealer upon purchase. They will pair your account to the registered vehicle for security purposes.

Note that some apps vary in features, but most new models have an unlock innovation from the app. For instance, the Toyota car app enables you to lock and unlock.

Other more advanced apps allow users to immobilize stolen cars, produce vehicle health reports, and start or stop the engine. Other more complicated models use sophisticated locking technology like the Hyundai i10 car.

This car has an auto-lock feature, so disabling it by holding the lock button for 5 seconds would save you the trouble of getting your locked keys in the car.

Here are some apps for different car makers

  • BlueLink app – This app is for Hyundai. Open the app, and you will see the unlock button. Tap it to provide the pin, and you are all set.
  • myChevrolet app – This app is not limited to only locking and unlocking. You can also use this to start, stop, and even horn the car. You can also use this if your carmaker is GM.
  • NissanConnect – The NissanConnect app is for Nissan cars, as the name suggests. The NissanConnect is a standout because it diagnoses your vehicle and gives you health reports.
  • Toyota app- Recently, the company has also added the smartwatch feature so you can lock and unlock the car through your wrist.
  • HondaLink – This app works like the other apps and lets your Amazon packages be sent to your car.
  • FordPassTM – The app also allows you to pay your monthly lease aside from unlocking your car.

Method 3: With a Screwdriver

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

  • Find the unlock button of the car.
  • Carefully insert the screwdriver between the door and the lock. Using a flathead screwdriver and older car models, you can easily reach the lock button and pull it. If not, follow the next step.
  • Now there is a slight gap between the door and the frame. Insert the coat hanger or any rod with a hook to reach the lock, then pull it.
  • Carefully remove the coat hanger or the rod from the car, followed by the screwdriver. You have to follow this sequence to avoid any damage.

Method 4: Use a Tennis Ball and a drill/screwdriver

Without tools, the tennis ball can be of good use if you have the skill. The tennis ball technique is a long debated method of unlocking the car. However, some have claimed it worked, while others need more practice.

  • Create a hole in the tennis ball with a drill or a screwdriver.
  • Place the tennis ball hole in front of the key. We will try to pull the discs inside the keyhole through the pressure applied by the tennis ball.
  • Pump the tennis ball repeatedly until you hear a slight clicking sound.

Method 5: Call Someone

If the hacks mentioned above did not work, calling someone can be your last resort. First, check if there are any local locksmiths available in the area.

If there is none, some locksmiths specialize in how to get into a locked car like the Pop-a-lock. They would look into your vehicle lock and make the key in less than 10 minutes. It would also be better if you knew your lock type to help them make the key faster.

For their service, prepare to shell out $4 to $10 for older models of cars. However, prices can skyrocket for luxury models between $250 and $450.

If you do not want to foot the bill and wonder, ‘who do I call for free?’ You can call 911 to alert the police or the fire department.

Calling them is extremely helpful, especially in an emergency when a locked child or a pet is inside the car. However, they might smash your window car in some extreme emergencies if their lock-picking tool cannot handle the situation swiftly.
