Body, Locking and Security, Comfort Access, and Wiring Diagrams and Functional Description for BMW G05 X5 xDrive40i SAV
The remote key will be referred to as an ID transmitter for automobiles with comfort access.
Without actively using the ID transmitter, the vehicle can be unlocked and locked using the comfort access. The ID transmitter within the passenger compartment or close to the car is automatically recognized by the vehicle.
I appreciate your post. Yes, I am aware of the CA system, but the fact that it never turns off (except when the car is inactive for a while) makes it vulnerable when you park your car and carry something in your pocket or purse. However, I do prefer the convenience of being able to unlock and start remotely and not have to wait until I can actually touch the car’s handle. I could carry the key card or my cell phone that has been programmed with a copy and leave the fob at home, or I could use the connecteddrive feature, which allows me to open doors or start the car over the internet for $50 per year.
I haven’t left the house without the key fob yet, but I know that a lot of people do. Sure, there’s less risk of that occurring in my small town of Augusta, Georgia, than, say, Los Angeles or New York City, but still… the X5 is reportedly one of the most stolen vehicles. However, it does strike me as strange that the fob may be completely disabled with just a few key pushes, and yet I cannot see any mention of this in the instructions. Here is a little video made by a man who discovered he could do it on his recent Toyota Tacoma:
To summarize, hold down the lock button while pressing the unlock button twice. Until another button is touched, the RF transmitter stops transmitting the CA freq/code. If the owner remembers to use it, Easy Peasey should entirely resolve this issue. If you click the lock button twice, MB reportedly behaves in the same manner.

Does anyone know if this may be done without removing the batteries by pressing a series of buttons; it seems that a double click on the lock button works on Merc keys.
The fact that thieves are adopting remote key reading technology more and more worries me.
When you’re at home, apparently keeping the key in the refrigerator works (makes sense). I’m also aware that signal blocking pouches are available, but those take away somewhat from the simplicity of keyless entry because they add yet more item to juggle in your pocket.
Yes, that’s true, but if it could be disabled with a single double-press of the lock button, like Mercedes does, and then reactivated with the usual single press to unlock, I wouldn’t mind pressing a couple more buttons to dissuade criminals.
To realize how susceptible our automobiles are, one simply needs to skim through the many news releases describing how simple it is to steal cars with keyless ignition.
Can keyless entry be completely disabled? It will take more effort than a standard keyfob if you have to click the button twice to turn it on and off.
Actually, I wasn’t referring to keyless entry; instead, I believe I was referring to comfort access, which requires me to click the top button on the key fob to unlock the vehicle.
According to reports I’ve read, thieves can copy your key onto a blank, open your car, and drive away if they can detect and amplify the signal from your key within an acceptable range (I’m not sure how close their detector needs to be). They don’t need to access your car’s OBD port, therefore it appears that the entire process only takes a few seconds.
Yes, but the peace of mind is undoubtedly worth a few extra button presses to turn the key off and stop it from sending a background signal.
It appears like Mercedes has taken this into consideration because all it takes to turn off the keys is a double-press of the lock button.
How can I make a BMW key function to start my car?
It is still important to activate your new BMW key fob after purchasing one that has been customized for your car. recent automobiles:
- Use your current fob or key blade to unlock your car.
- Insert the fob in the ignition slot or hold it up to the key marking on the side of the steering column.
- Keep pressing the start/stop button until the no key warning goes away.
- To start your car, depress the start/stop button once, then release it.
Before using the Comfort Access option in E-series vehicles with keyless entry, you might also need to reprogram your car to delete your old key profile. It is important since E-series automobiles only let you save two Comfort Access-equipped keys in the memory of the vehicle. In order for the Comfort Access to function if you purchase a new key, you must first deactivate the old one and code your vehicle.
Please be aware that this procedure cannot be completed using a key that has previously been paired with another vehicle or a used key. Additionally, older BMWs require a distinct key programming procedure.
not using a key to start the engine
This one may undoubtedly come in handy during freezing winters or sweltering summers. Many of you might not be aware of this, but you can really run the engine of an E-Series car while you’re somewhere else without needing to leave your keys in the ignition.
Simply turn the ignition key once and press the start/stop button to get started. Then turn off the engine, remove the key, and press the start/stop button once more. Simply because the CAS control module is still awake and has read the signal from your key, your engine will start without a key. Now that the climate control is on, you may turn it on while inside your home, walk out of the car, lock it, and leave it to cool or heat up.
BMW keyless start may also be very helpful if you own an E-Series BMW with comfort access or any F/G-Series vehicle when you need to start your car fast and leave. The road is yours once you get inside your BMW and make sure your key is nearby.
How can I turn the engine on and off?
There is no need to fiddle with a key to start the engine because your BMW comes equipped with our Comfort Go system as standard. The ignition can be turned on by merely pushing the Start Stop button once while the key fob is still in the vehicle. The engine remains off but all systems start up. By depressing the brake pedal and then pushing the Start Stop button, the ignition and engine are started simultaneously. For models with manual transmissions, just depress the clutch pedal while applying pressure to the brake pedal, and then push the Start Stop button. Your BMW has an Auto Start Stop function that turns the engine off when you brake to a standstill, such as waiting in traffic or at a light, in order to minimize fuel consumption and emissions. The moment you let up on the brake pedal to resume moving, the engine fires up. Simply tap the tiny button located above or next to the Start Stop button to disable this feature if you wish. The Auto Start Stop feature has been turned off, according to an LED light. To reactivate, merely push the button once more. For comfort or safety, there are several circumstances under which Auto Start Stop won’t turn off the engine or when it will. The owner’s manual contains a complete description of these conditions. Keep the brake pedal depressed while stationary and push the Start Stop button to completely turn off the engine. The controls and audio outputs will continue to function. When the handbrake is engaged and the proper gear is chosen, it is safe to get out of the car. When the car is locked, the music and display are then turned off.
How do I stop the signal from my car key?
The key fob’s signal must be blocked if keyless theft is to be avoided at all costs. While some manufacturers, like Mercedes and Subaru, permit users to turn off their key fobs once they exit the vehicle, there is a good alternative for other users.
When at home, putting your keys in a metal-lined “Faraday box” or pouch will block the signal that your key fob is sending out, making it impossible for burglars to steal it. Even though keeping metal tins around the house is typically a good idea, a dedicated Faraday pouch might be more portable and prevent signal relay theft when the owner is abroad. There are some that defend against the same relay-based security vulnerability that threatens current bank cards and cellphones.
However, it’s crucial to not take the box or pouch for granted. Check to see if your car doors are still open when the fob is within the pouch to make sure it works.
How can car key fob signals be blocked?
Due to their metallic lining, signal blocking pouches can prevent entry to your automobile by preventing your car key fob from broadcasting its code to the vehicle. The pouch’s metallic lining Image prevents unauthorized parties from intercepting signals from the remote key fob.
How do I deactivate my wireless key fob?
When starting and especially when restarting the automobile, completely disabling keyless is a pain (cue grabble for keys and hold next to start button).
To effectively end keyless entry, learn to put your key in sleep mode when you need it (when you go home or are out and about, for example). Red light blinks twice while you hold down the lock button and hit open twice. Now keyless entry is blocked. When a key is pressed, it becomes active again since the car needs to be opened.
Can key fobs be turned off?
Yes, your key fob can be removed from the system if you lose it. If the key fob is picked up by someone else, this will stop it from being used. Make sure to carefully follow the instructions since different security systems will have a different procedure for erasing the key fob.
A BMW can operate without a key fob.
You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.
Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.
Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
