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.

A number of updates and new services for BMW automobiles have just been published. BMW owners may now choose from a variety of other options in the ConnectedDrive Store to add to their vehicles in addition to the “Uneven Road Surface alert” feature. One of them allows you to remotely preheat the temperature of your BMW vehicle, and it is called “Remote Engine Start.” While Remote Engine Start has been a feature of BMW vehicles from MY 2019, it is now also available as a new “Function on Demand” that can be added to eligible cars that weren’t initially equipped with it. This functionality can be purchased through the ConnectedDrive Store.
Through Remote Software Upgrade, the new functionality can be downloaded and installed wirelessly. This is a fantastic feature for the sweltering summer and icy winter months. You can preheat the interior by turning on the heat or the air conditioning while starting the engine from inside your house or place of employment.
Simply tap a button in the My BMW app to turn on Remote Engine Start, and your BMW’s engine will start, allowing the cabin to reach the ideal temperature. A triple-click of the lock button on the BMW key fob will also activate Remote Engine Start.

Repeat the procedure in case the engine stalls. If not, your efforts were successful.

Can a dead key fob be used to start a push-button vehicle?
Okay, so you don’t have a spare battery and your key fob is dead. Not to worry. With a dead key fob, starting and unlocking your car is actually quite straightforward.
The system is typically built to function with a remote that is entirely or partially battery dead. Naturally, the specifics of utilizing a dead key fob will vary depending on the model of your automobile, so consult your owner’s manual for details. Here are a few tried-and-true methods that apply to a variety of automobiles.
Why is my key fob unable to unlock my car?
It can be quite aggravating and even hazardous if your key fob won’t open the door to your car, especially if you have a young child or pet locked inside. Here are a few explanations for why your smart or remote key fob isn’t opening the door, along with solutions.
Any of the following could be the source of your issue if nothing happens when you push the unlock button on your remote control or key fob:
Your remote control or smart key fob’s battery is either dead or too low to maintain a strong signal. Replace the battery by opening the fob.
Your vehicle’s receiver(s) for the keyless entry system may not be receiving the signal from the key fob. When pressing the unlock button, try holding the fob close to the door handle. If it opens the door, there might be an issue with the key fob’s battery, the keyless entry antenna, or the wiring.
The unlock button on the key fob itself can be problematic. Try the panic, trunk release, and lock buttons. If the other buttons function properly, a faulty unlock button is the issue. You’ll require a fresh key fob (which will have to be programmed to your vehicle). The fob may be damaged, the keyless entry antenna, or the wiring may be at fault if none of the other buttons function after you have tried a new battery in the fob.
Your key fob’s entry code is missing. Every time you use the key fob to unlock or start your car, the rolling code that many automobiles employ changes. It can be necessary to have the fob reprogrammed by a car dealer if a communication error has corrupted the coding inside.
The electric door locks might be broken. The power door locks could not be able to unlock due to a problem with the wiring or control circuitry or even a blown fuse. To find the defect, the electrical system will need to be further diagnosed.
Your car’s battery is nearly dead or very low. Before the power doors may unlock, the car battery may need to be changed or given a jump start. Of course, you won’t be able to open the hood until you find another way to enter the car.
If your push-button car won’t start, what should you do?
Your automobile may have a dead battery if your keyless entry system is functional but your engine won’t start. Check the battery voltage with a voltmeter to make sure that this is the issue. The battery needs more voltage to start the automobile if it has less than 12.4 volts.
