Nope. Even if there was a means to start reverse communication, there is nothing you could do to make it discoverable because the fobs lack a speaker.
Some vehicles, but not the i3, have two-way key fobs with some form of sound generator.

Can you track a missing key fob?
Despite being highly technological, key fobs don’t come with a built-in tracking feature just yet.
Fortunately, you have lots of third-party tools at your disposal to monitor your key fobs till then!
This is essentially a tiny keychain-sized fob that you can attach to your key fob (or your phone, wallet, vehicle keys, or anything else that has a propensity to disappear!)
These key trackers connect to your phone via Bluetooth; don’t worry, even the most affordable models typically have a range of several dozen meters.
Your key tracker might, depending on the manufacturer you select:
- Make a noise to aid in finding it
- GPS can be used to locate it.
- When you are a specific distance away, notify you.
Once everything is set up, all you’ll need to do to find your key fob is pull out your phone and use the app that is included — no more frantic searching or needing to go back a step or two!
A dead key fob will a BMW start?
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.
What It Does
The processors and keys of some automobiles can hold more data than those of others. More personal information is reportedly stored in the key fob of BMW vehicles than any other automaker.
Your car key is very much trackable to anyone nearby if it offers keyless entry and push-button starting capabilities. A signal that your key produces can be tracked, even hijacked, copied, and used to break into your car. Although it does not happen frequently, it does happen more frequently in our modern, technologically enabled environment.
Not simply the automobile keys are capable of storing data and being exposed. The internal computer, keys, locks, and immobilizer systems in current cars can all be hacked. Once the security is breached, a hacker has access to the vehicle and can then install viruses and tracking software, copy or decode keys, and even take your car. You may really use a very straightforward solution to stop key cloning and data scraping when it comes to your keys.

Maybe—but don’t get your hopes up—if it’s the proper kind of remote and you have lots of time and technical know-how.
You’ve once again misplaced your automobile keys. You’re certain they’re in your home, but despite looking under the refrigerator and between the cushions of your couch, you were unable to locate them. You have a keyless remote that appears to be in communication with your automobile, and you are wondering if there is any way to make it speak with you and let you know where it is. “Theoretically, it is feasible, according to electrical engineering and computer science doctoral candidate Phillip Nadeau, “but it depends on the kind of remote-entry system we’re talking about. Even then, it can be difficult based on the manufacturer and technologies employed.”
Remote Keyless Entry (RKE) and Passive Keyless Entry (PKE), the two primary categories of keyless remotes, operate in various ways. Only when you push a button on the remote control do RKE devices send a radio signal to your car. Nadeau says that “these gadgets are often solely outfitted with a transmitter.” Unfortunately, this prevents you from calling the remote. It can’t hear you any more than a skeleton key can.
Your chances are improved if you have a PKE remote. You don’t need to press buttons with PKE devices to lock or unlock your automobile. According to Nadeau, “the car transmits a signal that simultaneously powers the remote and requests a legitimate authentication code to open the car.” Similar technology is used by RFID card scanners to grant you entrance to a building without requiring you to take your ID card out of your pocket. A PKE remote, in contrast to an RKE device, includes both a transmitter and a receiver, allowing it to hear you call it using specialized radio equipment while you’re just acting like your automobile! Theoretically, you could create a special gadget that doubles as a radio transmitter and receiver, retransmitting the signal from your car and waiting for a response from your keys. However, if you have the technological know-how to build such a device, it should work. This is not a simple or cheap option.
According to Nadeau, as long as you have a lot of free time. “To elicit a response, the interrogator must be a short distance from the distant.” Most of the time, this proximity restriction is helpful since if PKE remotes had a long range, someone might steal your automobile while the keys are safely inside your home! However, it also means that in order to locate your keys, you will need to search every inch of your home with your tools. You might as well go back and rummage through that junk drawer one more time rather than spending the time and money developing some fancy radio equipment in order to find your keys.

Step 5
A call from the BMW dealership letting you know your replacement key has arrived should be expected. You can either pick up your replacement key there or ask the service manager to send it to you.
- Before requiring you to replace the entire engine control unit, BMW would only let you order nine replacement keys. Your BMW’s engine control unit replacement could cost $5,000 or more.
- vehicle’s license plate number
- driving permit
- registration for vehicles
- Avoid calling a locksmith to assist you in finding your misplaced key. While a locksmith might be able to help you get back into your car, interfering with the sophisticated locking mechanism could result in long-term damage.
What should I do if my BMW key is lost?
If you still have one key, you must bring your car, one piece of personal identification, one form of address identification, and the V5C logbook to your selected BMW Center*. You will need to make arrangements for your automobile to be delivered to your preferred Center along with the necessary documentation if you have lost both keys and are unable to access the vehicle.
* A photocard driver’s license cannot be used for both address identification and personal identification.
To keep you safe, our Centers are required to adhere to these security precautions. Additionally, you’ll have to sign for your new key upon picking it up.
The cost of a BMW key fob
The price of a 2020 Toyota Sienna fob was comparable. Dealers, however, gave prices as low as $150 to replace a key fob for a 2017 Honda Accord. A number of BMW retailers claimed that the additional security features built into the 2020 X5 key fob justifies the roughly $500 they spend to replace and program one.
Does BMW have keyless ignition?
I’ll use the following scenario as an example: The passenger exits the vehicle with the key in their bag as I begin to park, and I later receive a notice that the key is missing.
How far/how long can the vehicle be driven in this manner? What follows is? Will it quit or keep running until you manually turn it off?
I’m not sure if it’s a problem; as long as the driver’s key starts the vehicle, I don’t think it matters if a passenger has a key.
Yes. However, he meant that while the passenger has the key and walks away with it, the driver does not.
I can relate because I’ve been in a similar circumstance before. Sometimes when I hand my wife the key, she keeps it in her bag while I’m driving. And when we arrive there, whether it be home or another location, she exits the vehicle carrying it. And when that occurs, the auto issues a missing key message.
Until you turn off the engine, you can keep driving. To remotely unlock and lock the vehicle without a key, remember to configure the ConnectedDrive app on your phone. I was once in a scenario where this helped me.
So that I always have a spare key, I’m considering just keeping the key card in my wallet. The fact that I might never use it and prefer slim wallets is the only thing keeping me from doing it.
I used to have mine working fine and kind of cheated by putting the card in the rear of my iPhone case, but I eventually gave up on the notion out of concern for losing my phone.
There is a rumor that the upcoming iOS upgrade will have a feature that can be used as a car key, however it is unclear if this will work with the G20.
How do I locate my electronic car key?
Electronic vehicle keys, which were originally made available in the 1990s, are a practical way to open your car door or trunk from a short distance. This saves you the time and hassle of having to enter a key into a lock and turn it, which can be uncomfortable in inclement weather. Being unable to access and operate your vehicle due to the loss of your electronic keys might be upsetting. There are a few things you may do if your electronic keys go missing.
The garbage, drawers, refrigerator, your handbag, your shirt and trouser pockets, your coat pockets, and, if your car is unlocked, the ignition, seats, and floorboard of your vehicle, should all be searched for your keys.
If you have a sonic key finding gadget, use it. Your electronic key will respond by making a loud noise and flashing a bright light when you press the “find” button on one of these gadgets. The sound and light will make it much simpler for you to locate your key if it is close.
Retrace your movements from when you last used your car keys, being vigilant and diligent in your search. Examine areas like the gutter or the shrubs close to your parking space, as well as areas like your desk, where you may have accidently left your keys after getting out of the car. Call your friends to see whether you left your keys with them if you were at their house, in a shop, or at a restaurant.
How can I locate my missing keys?
Put your detective hat on and attempt to recall when you last had access to your keys and everything you did after that. Retrace your steps and check every area of your Texas home where you might have dropped your keys unintentionally. As you get ready for the day, it is simple to toss them on the kitchen counter, next to the bathroom sink, or even next to your shoe rack.
