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.

- From the key fob, take off the emergency key blade.
- Using the metal blade, unlock the driver’s door. (An alarm may sound.)
- the ignition slot with the key in it.
- If your BMW lacks an ignition slot, set the keyfob—not the metal blade—next to the steering wheel’s right side. Take note of the steering wheel’s key symbol.
- Put your foot on the brakes and keep it there. Make sure to depress the clutch if your BMW has a manual transmission. Select Stop/Start from the menu.
The dashboard can display a check control message claiming that the key was not recognized. Either the ignition module has an issue or your key is faulty.
One more time, repeat the process, making sure there is never more than a two-second pause between each step.
A Straightforward, Economical Fix for the Car Not Starting
We replaced the key fob’s battery after returning to the store. The customer returned to her vehicle, and guess what? It launched right away.
The key fob’s dead battery was the root of the entire issue. The car was unable to detect the key or its transmitter because of the dead battery. It wouldn’t start the car, lock or unlock the doors, or do anything else. And the window’s small movement was the only hint we had.
The lesson of the story is that the majority of modern cars require the transmitter from the key fob to operate. Don’t wait to get a new key fob battery if you think your old one is fading. You can become stranded if you procrastinate. Additionally, if your automobile suddenly refuses to open or start, consider whether the key fob battery might be to blame.
What do I do if my key fob stops working?
The Family Handyman claims that you can still start your car even if the battery in your key fob dies. Put the metal key back in the fob after using it to unlock your doors; then, instead of pressing the “start” button with your finger, use the fob. Many manufacturers utilize this backup device to make sure the car can start even if the key fob is dead.
Now, the Mini has a slot where the key fob can be inserted to start the vehicle. But at this time, this design seems a touch dated. This is why it’s always a good idea to consult your car’s manual.
Some Mazdas and a few other vehicles may have an actual key slot along the steering column, according to the Family Handyman. The least frequent method to start a car with a dead key fob is this, though.
How is a BMW key fob with push-button start programmed?

Will a dead key fob prevent a car from starting?
If your key fob isn’t detected inside the car, the keyless entry system won’t start the engine. The system probably won’t be able to tell when the key fob is inside the car if it has a dead battery, which will prevent the engine from starting. By pressing down while placing the fob on the start engine button, you can get past this problem. Even though this should enable your engine to start, it is still beneficial to change the fob batteries whenever you have the opportunity.
Why won’t my BMW key fob function now that the battery has been changed?

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.
Will a dead key fob deplete the battery in my car?
We frequently receive inquiries like these at the shop. Yes, it is the correct response. Your key fob can eventually deplete your battery if you keep it in your car when it is not in use. Even when not in use, the key fob continuously transmits a signal to the vehicle, which consumes a tiny amount of electricity. So, if you keep your key fob in your car for a long time, the battery will ultimately die. If you find yourself in this predicament, you might try using a jumper wire or a portable battery pack to jump start your automobile.
Additionally, it may not be a good idea to leave your key fob in your car overnight or even just hanging nearby. The key fob may speak with your automobile if it is too close, which could drain the battery.
