Understand the BMW Keyless Ignition System
The keyless ignition system is a common feature in most modern luxury cars, including BMW models. With this technology, you can start your car without using a physical key or even pressing any buttons on the remote control.
What is a BMW Keyless Ignition System?
A BMW keyless ignition system allows drivers to start their vehicle by pushing a button located inside the car while carrying a fob that sends out a code when it is within range of the car’s receiver. It provides convenience and ease-of-use for drivers as they do not need to insert a traditional key into the ignition slot to get started.
The BMW keyless ignition system also comes with an advanced security feature where the engine shut off automatically if it doesn’t detect the right key fob signal or if someone tries to break-in.
How does a BMW Keyless Ignition System work?
The BMW keyless ignition operates via radio frequency identification (RFID) technology. The system relies on the communication between two parts: the transponder chip which is embedded in the key itself and the receiver inside the car’s computer system.
When the driver approaches the car with the key fob, the computer recognizes the unique RFID signature from the fob and unlocks the doors without requiring any action from the driver. Once inside the vehicle, the driver then presses the brake pedal and pushes the start button to begin the engine.
If you forget to turn off the engine before getting out of the car, the keyless ignition system will automatically switch off the engine after a certain period of time, therefore reducing unnecessary fuel consumption and pollution.
“Once behind the wheel, the starting process involves simply depressing the brake pedal and hitting the Start/Stop button. There’s no need to insert anything into the ignition—it all happens seamlessly when you’re within range and hit that Start/Stop button.” -Car and Driver
It is important to note that there may be instances where the key fob battery dies or gets damaged, thus losing its RFID signature and rendering it useless. In such cases, drivers can use a backup method by putting the physical key hidden inside the fob to manually unlock and start their vehicle.
“If the remote control key is malfunctioning, for example if its batteries are flat, the car can still be unlocked with the spare key tucked in the back of the primary remote.” -BMW Malaysia
The BMW keyless ignition system is an innovative technology designed to offer convenience and security as well as reduce fuel consumption and pollution. Drivers don’t have to worry about misplacing or losing keys as they only need to carry the key fob around, making starting your car effortless even from a distance.
Try to Use a Spare Key Fob
If your BMW is equipped with an electronic fob, you may be able to start the car with a spare key fob if you’ve lost or misplaced your primary fob. Here’s how:
Locating the spare key fob
Before attempting to use a spare key fob to start your BMW, make sure you have one on hand. If the spare fob was supplied when you purchased the vehicle, it should be in a safe place such as a locking drawer or home safe. If you don’t have a spare fob, contact your BMW dealer to order one.
Programming the spare key fob
If you are using a new or unprogrammed spare key fob, you will need to program it before it can be used to start your BMW. Follow these steps:
- Insert the primary key into the ignition and turn to the “on” position without starting the car.
- Press and hold down the “Unlock” button on the working key fob while pressing the “lock” button three times. Then release both buttons.
- Within five seconds of releasing the buttons on the working key fob, press any button on the spare key fob. The doors should lock and unlock to confirm successful programming.
- Repeat Step 3 for additional spare key fobs if desired, up to four total fobs per vehicle.
Note: These programming instructions apply specifically to BMW models that use a diamond-shaped key fob. Other models may require slightly different programming steps, so consult your owner’s manual or dealership for guidance.
Using the spare key fob to start the car
Once you have a spare key fob programmed and ready to go, starting your BMW without the primary key will typically involve these steps:
- Insert the spare key into the ignition slot.
- Press down on the brake pedal.
- Push the “Start/Stop” button while holding the clutch down (for manual transmissions) or keeping the transmission in park (for automatic transmissions).
- The engine should turn over, allowing you to start driving your BMW as usual.
If all else fails or you don’t have a working spare key fob available, contact a BMW dealer or certified auto locksmith for assistance with unlocking and/or starting your vehicle.

Manually Unlock the Doors
If you own a BMW, you know that it comes with some advanced features such as keyless entry. However, what happens when your BMW key fob malfunctions or loses battery power? In such cases, you need to know how to start your BMW without the key. This guide explains how to unlock your BMW’s doors manually in a few simple steps.
Locating the manual lock on the door
The first step is to locate the manual lock that allows you to unlock the doors physically. The position of the manual lock might vary depending on the model and year of your BMW vehicle. Typically, for most BMWs, the manual lock is located behind a small flap cover near the door handle on the driver side.
Unlocking the door with the key
If there is no power left in your car’s batteries and you have no other way of opening the doors except using physical manipulation, use the emergency trunk-release cable. Reach through the center rear seat pass-through into the trunk access compartment and pull the release cable. At this point, use your key to turn the door lock manually. If you do not have a key, you may be able to apply a stronger magnet to the outside of the driver’s-side door near where the lock cylinder is positioned. Most models from recent years require at least two strong magnets; older ones may only require one.
Opening the door from the inside
If you are already inside the car but unable to open the door normally, seek out the unlocking mechanism and operate it to get out. Depending on which BMW model you’re attempting to reach, its release mechanisms could be electronic or mechanical.
Disabling the alarm
When you disconnect the battery, or when your BMW experiences a sudden power outage, it triggers an alarm that goes off and can be quite irritating. To disable this alarm while you are unlocking the doors of your BMW manually:
- Locate the hood switch found on the driver’s side fender well under your hood.
- Pull up on this switch to cut the alarm.
If you have tried all these steps but no luck, consider contacting BMW roadside assistance for help.

Use a Jump Starter Pack
Locating the car battery
The first step in jumpstarting your BMW without a key is to locate the car battery. In most models, you will find the battery under the trunk floor mat or engine bay. If you have trouble finding it, consult your owner’s manual.
Once you have located the battery, park another vehicle with a fully operational battery close enough so that both batteries can be connected with jumper cables.
Connecting the jump starter pack
Now, connect the jump starter pack to your BMW’s dead battery by following these steps:
- Attach one end of the red (positive) clamp on the jump starter pack to the positive terminal on your BMW’s battery.
- Attach the other end of the red (positive) clamp to the positive terminal on the booster car’s battery.
- Next, attach one end of the black (negative) clamp on the jump starter pack to the negative terminal of the booster car’s battery
- Finally, attach the other end of the black (negative) clamp to an unpainted metal surface near the dead BMW battery. This completes the circuit.
After all clamps are securely attached turn on the boost and start the vehicle with the good battery to get its current flowing into the dead vehicle. Allow this for about 5-10 minutes before starting your BMW. It should start up properly now.
“Jump-starting recreationally parked cars may seem like something best left to mechanics. However, given proper instruction and safety precautions, the average person can easily jumpstart their flat battery.” -Robert Duffer
A jump starter pack is a quick and effective way to start your BMW in case of an emergency. Keep one in the trunk of your car so you’re never caught off guard! It’s crucial to maintain the right safety levels when handling electricity, always ensure all terminals are safe before starting or connecting any cables as a wrong move can result to serious injury.
Replace the Battery of the Key Fob
The BMW key fob is an essential component to start your BMW car without a physical key. However, if your BMW key fob battery dies, you won’t be able to unlock or lock your vehicle using it. Fortunately, replacing the battery of the key fob is an easy process that you can do at home.
Locating the battery compartment
The first step in replacing the battery of the key fob is to locate the battery compartment. Depending on the model of your BMW, the location may vary. Generally, you can find the battery compartment by searching for a small slot on the back of the key fob. Some models have a specific button that opens the battery compartment, so make sure to check your owner’s manual if you’re having trouble finding it.
Removing the old battery
Once you’ve located the battery compartment, you need to remove the old battery. To do this, use a small flathead screwdriver or another thin object to pry open the cover of the battery compartment gently. After removing the cover, take out the old battery and dispose of it properly. Be careful not to damage any other components inside the key fob while doing this.
Installing the new battery
After removing the old battery, it’s time to install the new one. Make sure to buy the correct type of battery specified in your owner’s manual or consult with a professional if you’re unsure. Once you have the right battery, simply place it in the battery compartment with the positive (+) side facing up, and snap the cover back into place. Double-check that everything is securely in place before moving on to the next step.
Testing the key fob
Finally, you need to test the key fob to make sure that it’s functioning correctly. Hold the key fob near your car and press any button on it to see if it unlocks or locks your vehicle. If it doesn’t work, try repeating the process again, or replace the battery with a freshly charged one.

Seek Professional Assistance
If you’re wondering how to start a BMW without a key, it’s important to note that attempting to do so can damage your vehicle and possibly even cause injury. As such, seeking professional assistance is the safest and most practical option.

In some scenarios, you might need to provide proof of ownership or other identification documents before any steps can be taken. This is especially true if you’ve lost your keys altogether.
To wrap up, starting a BMW without a key is not advisable and can lead to severe damage or even harm. Instead, it’s best to contact a professional who knows how to solve the problem in the safest way possible.
