How to Unlock a BMW with Keys Locked Inside? 

As we said earlier, there are different ways to unlock a bmw with keys locked inside. Among them, the most possible methods are going to be described below: 

Use the spare key 

BMW cars usually come with a set of keys. So, once the first key gets locked inside the car, it’s better to try to find the second key to unlock your bmw. 

Unfortunately if you lost your spare key or couldn’t find it anymore. But don’t worry. Here  are more methods you can try to unlock a BMW with keys locked inside. 

Use the key fob

When you own a bmw, you’re probably enjoying a keyless entry system. So, if you have the key fob in your pocket or wallet, it will surely help to open the door.

To do so, press the ‘Unlock’ button of the keyfob until the door opens. But if the key fob doesn’t work or you have left at your residence, then the following tricks are available for you. 

Access the car’s online app 

With the blessings of technology, you can add a key to your compatible iPhone or Android mobile phone to lock, unlock, or start the BMWs. It even works without taking out the phone using the Ultra Wideband Technology. 

To unlock a bmw with keys locked inside, make sure that you are logged into your My BMW App. Now open the app and go to “Unlock and Drive” to unlock the car. 

Use a clothe’s hanger 

One of the most common ways to retrieve bmw keys is using a straightened wire coat hanger. This process has five simple steps. 

  • Find a coat hanger and straighten it out with a pair of pliers. But make sure that you leave the curved end in its original shape. 
  • Now insert the hanger between the car window.
  • Then grope for a small pin with the hanger. Move the hanger around in the gap until you feel a small pin. 
  • Now loop the curved end of the hanger around the pin and pull it back towards the rear of the car.
  • Remove the coat hanger from the door after successfully unlocking the door. 

Unlock the car’s door with a string 

This is one of the most popular ways to unlock a bmw with keys locked inside. According to these methods, you’ll need to have a shoelace, or a fishing line, or any type of string that is thick enough. 

So, have a shoelace or a string and make sure that it is long enough (at least 2 m) to cover the window diagonally. Now make a slip knot in the middle of the string. 

Then slide the string in through the top of the door and try to fit it over the knob. Once you put the loop over the lock mechanism, pull the string ends apart to tie the knot and pull up. Here you go the car is unlocked!

Try a long rod and a wedge 

Another important way to unlock a bmw is using a long rod, a wedge, and an airbag. You can also use a car’s antenna as an alternative to a rod. This method can be so tricky but not so difficult at all. 

First, pull out the door frame by pushing the wedge and pumping the airbag. Keep it doing until you can put your finger between the gaps. Now take the rod and insert it through the gap. Once your tools are inserted, push your car’s unlock button.

But if your bmw features the anti-theft system, this process is not gonna work. In this case, you can push the car’s door handle to unlock it with the same rod.    

Using a metal scale

A metal scale can also be a useful tool that can help you to unlock your bmw with a key. To do so, first you should have a metal scale. 

Then bend it from the end. Once you’re done, gently push the scale near the lock toggle. Keep pushing, until the door is open.
