Open a BMW with a Dead Key Fob

How to Open a BMW with a Dead Key Fob

Mechanical keys are necessary for all models up to the new electric version, a mechanical key can be used with them, but you’ll have two additional options as well.

• First, if you are already inside, click here for help getting started!
• Second, for video help, click here!
• Finally, if you need another manufacturer, click here.

Retrieving the Mechanical Key

For your BMW, press the button on the back of the remote control (or ‘clicker’) and pull the key ring end to remove the integrated key. The integrated or mechanical key can be used to unlock the driver’s door.

In 2014, BMW added themselves to the list of manufacturers hiding the keyhole or lock cylinder, and introduced a new, slightly redesigned key fob. The button in this case, is on the side, as shown. Press it and pull the key ring end to remove the mechanical key.

In 2015, in higher end models, BMW introduced a Display Key. The mechanical key is separate and should be carried in a wallet or purse! The Display Key itself can be recharged in the car (see the end of this page). If the Display Key goes dead and the mechanical key is not available, roadside assistance will be necessary.

EVs+

With the latest EV line, the iX, i4 and i5 so far, come new key fobs. The i4 and i5 have a traditional looking fob, very much like the second one above. Push the button on the side and pull the key away. However, it will need to be used in a very tight space and so needs to be “undressed”. Slide the frame down the key and remove (right). ICE powered 4- and 5-Series use this as well.

In the iX and newer (2022+) 7-Series ICE models the mechanical key is behind the chrome cover on the key fob. Look for the button shown (first image). Press it and pull away the cover in the direction of the larger arrow. Then rotate the mechanical key out from the fob starting with the key’s tip (second image).

Opening Your BMW

i4, i5, 4- and 5-Series

The electric models we noted above use a mechanical key for entry, as well. Lift the handle (right) of the i4 or i5 to expose the keyhole (black arrow). Newer ICE-powered 4- and 5-Series models use this handle as well.

iX and newer 7-Series

In the iX, note a small door on the far right in the entry opening. Push to release it and pull  it away to expose the key hole in the same spot (right). This handle has since spread to the ICE-powered 7-Series beginning in 2022 and will likely find its way to other models.

Note that once the key has been used in the lock, the door used to expose the key hole is now used to open the driver’s door itself. Pull it away to the left until the door unlatches. The actual door handle will not operate.

Both handle styles also feature a proximity detection pad. It is located somewhat in the middle of the driver’s door handle on the i4 (first image) and at the front of the driver’s door handle on the iX and 7-Series (right image). It is the knurled spot seen in the image. Touch an activated key card or the back of a smart phone with the BMW app to the spot and the door will unlock.

X1, X5, X6 and X7

Hiding the key hole was first seen in the X5 model in 2014 and the X1, X6 and X7 SUVs have been added since. Insert the integrated key into the opening of the driver’s door handle indicated by the arrow in the image. Press upwards and remove the cover. The cover comes off onto the key itself, and quite easily. Unlock the door using the integrated key in the now exposed door lock.

Yes, the effect is that of pulling off a piece of your car, but it is necessary to get inside! The cover can be snapped back on, but the priority now is to simply get inside your car. Check out the video here for more help.

7-Series

Starting 2015 in the 7-Series only, a new style hidden key hole a new cover removal process is featured. The directions from BMW are a little confusing, so do this carefully. It turns out to actually be quite simple.

It starts as a one-piece door handle (above) that must be pulled outward. With the handle pulled outward with your left hand, slip a finger from your right hand behind handle. Feel for a metallic release and push it outward. This will release the cap, which can be pulled away with the thumb and fingers of your right hand, exposing the key hole (right).

Again, you are removing a piece of your car. Its still ok!

Let go of the handle and use the mechanical key to unlock the door using the key cylinder now visible through the handle. Note that if you have a display key, the mechanical key is not integrated into the fob. It is supplied separately. Keep it with you at all times, or you will need roadside assistance.

5-Series, X5 and X7

A modified version of this was introduced in the 540i for the 2017 model year. It has since been introduced in the X5 and X7 SUVs. The same metal clip is behind what is a smaller cap. The cap is the last bit of chrome at the back of the driver’s door handle and is roughly the same size as the clip, making it easier to feel for.

Like the 7-Series, pull the handle out and slip a finger from your other hand behind handle. Feel for the metallic clip and give it a push. In this case, the cap will practically fly off. You are still removing a piece of your car and its still ok! Let go of the handle and use the mechanical key to unlock the door using the key cylinder that is now visible through the handle.
