How To Lock A BMW With Key?

Simply pressing the unlock button on the key fob’s top will unlock your BMW. Within the settings menu of the automobile, you may select whether to unlock all the doors or simply the driver’s door. The alarm system will also be engaged and all the doors, the boot, and the fuel cap will lock when you press the BMW roundel in the key fob’s center. When the lock button is pressed and held down, some models will also fold in the wing mirrors, close the sunroof, and any open windows. Press the boot lid button on the key fob’s bottom to open the boot lid while standing outside the vehicle. For BMWs with automated tailgates, holding it down will unlock the lock and open the boot. There is no need to be concerned if, in the odd case, neither supplied key fob is functional. The integrated key can unlock and lock both the glove box and the vehicle.

Using your BMW comfort access technology is method 1 of 1.

Lock and unlock doors as the first step. You must press the corresponding button for each function if your BMW is an older model without door sensors.

Simply touch the top arrow-shaped button to unlock the door. The driver’s side door will unlock after you hear the car beep two or three times; press the button once more to unlock the passenger doors. To lock the doors, press the round BMW logo in the center of the button.

Step 2 is to walk up to the vehicle and grip the handle. To unlock the door, simply go up to the vehicle while holding the smart key in one of your pockets and touch the interior of the handle.

When you exit the car while holding the key in your pocket, tap the ridged sensor on the handle’s upper right side to lock the door once more. It’s not necessary to push the buttons on the key if your later BMW car has more sophisticated comfort access technology, but it is an option.

  • Advice: Refer to your car’s manual if you’re unsure of the degree of comfort access technology it has.

Step 3: On older models, open the trunk. The trunk will unlock by just pressing the bottom button on your smart key, which should display a picture of a car.

Step 4: Use comfort access to unlock. With the smart key in your pocket, approach the trunk, wave your foot under the rear bumper, and the trunk will unlock.

Step 5: Start your car using an earlier model. Press and release the aStart/Stopa ignition button while the key is in the ignition, the buttons are facing up, and your foot is on the brake.

Your car should start once you click this button, which is to the right of the steering wheel.

Step 6: Start the automobile with a newer model. Press and release the aStart/Stopa button while holding the smart key in your pocket in the center console and your foot on the brake.

This is to your steering wheel’s right. Once you press it, the car should start.

Stop using an older version in step seven. Press and release the aStart/Stopa button once when the parking brake is engaged and your automobile is in the parked position.

The engine ought to shut off. As soon as the engine is turned off, press the key inward first, then pull it outward to release it, and put it somewhere safe so you won’t lose it. When you leave, be sure to lock the car by pressing the smart key’s center button.

Stop using the newer version in Step 8. When you stop your automobile, apply the parking brake, and briefly press and release the Start/Stop button.

When you leave the car, be sure to take your smart key with you and lock the door by touching the top right corner of the handle from the outside.

Anyone can benefit from BMW’s Comfort Access technology if they are bringing home groceries and have full hands, or even just for ease and convenience in general. Ask a Mechanic for some helpful suggestions if you are having problems with your Comfort Access technology, and make sure to get your batteries checked if you observe it acting strangely.

Remote starting

It’s cool to start the engine without the key. However, it is much more convenient to start it without even getting inside your car. However, your BMW must have the S1CRA “remote engine start” option in order for you to use your key fob to initiate the start-up process. Enter your VIN decoder here, and we’ll send you a PDF file containing all the vehicle’s specifications, including whether the S1CRA option is available.

For instance, to start your engine in the 2019 BMW X5, you must immediately press the lock button on the key fob three times while holding it down. You would also need to make sure that the’remote engine start’ capability is turned on in your iDrive settings beforehand. To achieve that, you must:

1) Access the iDrive menu.

2) Select “Car.”

3) Click “Settings.”

Choose “Climate controls” in step 4.

Pick “Preconditioning/ventilation” in step 5.

Visit “Remote engine start.” 6)

Choose “Start engine for climate control” (7).


Alternately, while the doors or trunk are open, you can push the black BMW emblem on the keychain, and as soon as you close them, it will lock automatically and sound the alarm.

When unloading groceries, I do this since I know my hands will be full. I fill up with an armful of groceries, hit the lock on the key fob with my elbow, tuck it away in my pocket, and then open the trunk. As soon as the trunk is closed, the doors lock and the alarm goes off.


Locking the vehicle with the key or the remote and then opening the trunk, setting the keys inside, is a terrific additional method for locking the key in a BMW with the Type-2 system.

If I don’t have a key fob, how can I lock my BMW?

If you don’t have a key and want to lock your car, enter from the passenger side, use the central locking button to lock the doors, open the passenger door, and then exit by pushing the knob (the black object that rises when you open the door) down and closing the door.

My BMW will it lock with the key inside?

Locking the vehicle with the key or the remote, opening the trunk, placing the keys inside, and then closing the trunk lid is a wonderful additional method for locking the key in a BMW with the Type-2 system.

Why won’t my BMW lock?

Modern automobiles come with technology that makes a number of tasks simpler and more practical. These conveniences rely on a number of intricate components that are vulnerable to damage, which makes this technology fail. There are various indicators that a BMW’s door locks are failing:

  • Your locks will become jammed. Even if you can make the locks function, they might occasionally become stuck in one. This is a warning indication of impending failure that has to be looked into right now.
  • Simply said, they won’t lock anymore. Although this is a clear indication of failure, there are a number of potential causes for it, and not all of them involve the BMW’s actual electrical system.

Sometimes, a problem with your key fob causes the doors to fail to lock. These key fobs are powered by batteries, which have a limited lifespan. Changing the batteries in the fob might be the answer.

If your fob is not the problem, a blown fuse can be. Your BMW won’t have the electrical power it needs to keep one or more parts of the car operating if any fuse blows.

If none of the aforementioned are the cause of the problem with your locks, your BMW may be dealing with poor wiring. Over time, wires deteriorate and become damaged. Although this is typical, the wires still need to be changed. The wires could corrode due to other broken components, leading to early wire aging.

When you enter or exit your car, your doors lock securely with the help of more components than just wires and fuses. Actuators are systems that are activated to physically operate the locks, and these systems degrade over time just like any other component might. Your locks might engage without being actuated by the fob or become stuck if the actuators aren’t working properly.

Is the BMW x3 auto-locking?

The Doors/Vehicle Access options have a setting for “lock in a few minutes.” But it’s possible that it won’t lock as quickly as you’d like. When the car was previously unlocked but no doors were opened, that locks the car. Without touching the handle or the key fob, there is no way to automatically lock the car.

My BMW key fob can I leave in the car?

Lock the vehicle with the bmw app while leaving the key inside. I appreciate the responses; nice. You can leave one key fob in the car and lock it with the other if you’re carrying both of them. Use aluminum foil to encase the Fob.

How is a Smart car manually locked?

How To Lock And Unlock Your Smart

The current smart key has three buttons, and your car should come with two of these keys.

Press and release button B once to unlock the automobile. The car will flash each of its indicators once to let you know when it has unlocked.

Press and release button A once to lock the automobile. The car will flash the indicators three times to let you know when it has locked.

When the lock button is hit, the indicators should flash twice. If they only flash once, one of the doors or the boot is not closed completely. Make sure the boot and both doors are properly closed before attempting to lock the car once more.

The key fob’s battery needs to be changed as soon as possible if the indicators flash nine times. The battery will have enough power to lock and unlock the car for about 100 additional times after this.

You can learn how to replace the key battery by clicking here. Since the boot can be opened with the key, it is a good idea to keep an extra battery there.

What does a BMW key’s diamond button do?

Does anyone have any knowledge of what the key fob’s diamond button is meant to do?

The included manual is incredibly succinct. It refers to a “Headlight courtesy delay feature,” although it’s not entirely clear what this feature performs. “If the standby state is switched on and the high-beam headlights are enabled, the low-beam headlights remain on for an of time,” the text states. Even if “… for a period of time” is meant to be “… for a length of time,” that still doesn’t adequately describe what this feature is.

According to the description, it can only be used when the automobile has just been turned off and the high beams are on. However, when the car is locked, the button appears to have some effect. The inside lights occasionally come on. The headlights occasionally come on. It is quite unpredictable and challenging to duplicate.

What experiences do others have? Has anyone figured out what this button’s actual purpose is?

It is unfortunate that it cannot be set to perform things like open the windows or sunroof, switch on the heating, or other things!

Mine has two options (330e in Belgium): turn on the lights in the house or turn on the air conditioning. In the options for the car, I can select the default function.

It briefly illuminates the headlights in my automobile. Excellent for illuminating the path to your front entrance or finding your car at night in a big parking lot.

Check the “Home lights” setting under “Exterior Light Settings” on your iDrive to make sure it is not set to 0 seconds.

My headlights now turn on for 10 seconds when I hold the diamond button on the key because I set mine to that duration (G20 330i).
