How to Use Your BMW Key Fob Remote
Although pre-programmed for your car, your key still needs to be activated in order to be used.
Hold your new key fob flat on the dim battery indicator next to the steering column to accomplish this. After then, keep pressing the start/stop button until the “no key” warning light goes out. To check that activation was successful, press the start/stop button once more.
If this doesn’t work, you might need to activate your new key while removing your old key fob from the signal range to avoid interference. To accomplish this, first unlock your BMW with the existing key before having someone carry the key a short distance away from your car. After that, you can push the start/stop button while holding your new key against the steering column.

How do I connect my car’s key fob to it?
Press and hold the “LOCK” and “UNLOCK” buttons on the key fob simultaneously until the locks cycle one more to program your keyless-entry remote.
Reversing step 6 by closing the door before entering the key may help if the above method doesn’t work because some Toyotas have a different approach.
How is the BMW key reset?
Remove the ignition key from the car. Press the BMW logo three times while holding down the unlock button, and then let go of the button. Repeat step 3 within 30 seconds after the initial key programming if you want to program any more keys. To finish the procedure, start the engine.
Why won’t my BMW key turn?
You’ll need a CR2032 battery if your key fob is functioning well but your BMW key fob battery has to be changed. Make sure you’re using the appropriate size of these tiny cells, sometimes referred to as “watch batteries.”
Why won’t my BMW key fob function now that the battery has been changed?
A dead battery is the most frequent cause of a key fob not functioning. Having said that, your keyfob might be having more serious issues. You might require a key fob replacement or perhaps auto door lock repair if your key fob stops operating after a battery change.
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.
How do I start my BMW remotely?
You can activate Remote Engine Start by pointing your BMW key fob at your car and pressing the lock button (the BMW Roundel) three times in a row.
Why doesn’t my automobile recognize my key fob?
Key fob battery failure The most frequent cause of a keyless entry system failing to send signals is a faulty battery in the key fob. Use the extra key fob to unlock the car and turn on the ignition if one is available. Use the key that is included in the spare fob if it is not available to unlock the door.
How is a key fob reprogrammed?
Turn the key back to the “Off” position while holding down the lock button on the fob. At least three times, go through this process, finishing with the key in the “On” position.
This notifies the electronic control modules in your automobile that the signal is coming from your key in the ignition, and it then saves the information.
Why did both key fobs fail to function?
As you may think, the battery is the main cause of failure for an electric key fob. Although you might need a ride to get to the store to get a replacement fob battery, this is a reasonably simple problem to fix.
Can I program my own car key?
There are a few manufacturers who will let you program a single key even if you don’t have a working key. Remember that you’ll still need to have the key cut to suit the ignition, which necessitates presenting the locksmith with evidence of ownership.
Nevertheless, it is far easier to do this than to program a second or third key:
- Turn the ignition to the on position after inserting the key. Just the electronics, leave the engine off.
- After 10 minutes and 30 seconds, switch off the light by turning the key.
- Restart the key, then wait another 10 minutes and 30 seconds before turning it off once more.
- Thirdly, repeat the procedure.
- To program the key, turn it back to the on position.
- In order to test your new key, start the engine.
Does my key fob require reprogramming after a battery change?
After changing the battery, you typically do not need to reconfigure the key fob. However, you might need to reprogramme it by re-pairing it with your vehicle if you’ve replaced not only the batteries but also some of the internal cabling and electronics.
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.
What occurs when the battery in your key fob runs low?
The transmitter’s range decreases as the fob battery gets weaker. This implies that for the key fob to operate, you must be close to the vehicle. When a smart key fob is in your pocket or handbag for automobiles with push-button starts, the car might not always detect it if the battery is low.
Does my BMW require reprogramming after a battery change?
Let’s first focus on what BMW battery registration genuinely is before delving into the procedure. Battery registration, to put it simply, is the process of notifying your car that a brand-new battery has been installed. Importantly, it must be done every time you replace the battery in your BMW, model year 2002 or later.
The car adapts the amount of energy required to recharge to operate at peak levels as your battery ages and gradually loses its ability to charge. The battery needs more charging the older it is. By registering your battery, you can inform your engine control module (also referred to as DME — Digital Motor Electronics) that a new one has been installed. As a result, the vehicle will reset the old battery statistics and won’t attempt to overcharge the new battery under the assumption that the old one is still in place.
In addition to registering, you must also code your BMW computer. No matter how different or similar your new battery is from your previous one in terms of specifications, it will still be necessary each time you change it.
What occurs with an unregistered BMW battery?
The servicing procedure “Register battery replacement” must be executed after installing a new battery. To let the power management system (software in engine electronics and an intelligent battery sensor) know that a new battery was put in the car, the battery replacement must be registered. The power management won’t work effectively if the battery change is not registered, which could result in certain tasks being restricted by particular electrical consumers being turned off or having their power consumption lowered. Power management will charge the new battery as if it were the old, worn-out battery, resulting in the replacement battery failing sooner than expected.
Important! The on-board computer’s display may show inaccurate values if the new battery hasn’t been recognized because of outdated information in the power management system (check control message “Recharge battery” appears even though the battery is new).
The power management in the Digital Engine Electronics (DME) or Digital Diesel Electronics (DDE) is alerted by a servicing function when a battery needs to be replaced. The following actions are carried out:
- 2. Changing a battery with a different capacity but the same kind (registration/conversion)
- 3. Changing to a new type of battery (for programming, conversion, or registration)
- 4. Software updates for the entire battery management system
For vehicles with EfficientDynamics, changes to the charging profile also impact how the Start/Stop system functions.
Car 1:
The battery is being replaced with an identical one. To inform the car that the battery is new, you register replacement so that the charging profile can be modified appropriately. If you don’t, the car will try to charge an outdated battery and eventually fail.
Car 2:
You replace a Standard LA battery with an AGM (or vice versa). Because the charging profile will be for the wrong sort of battery and accelerate battery failure, if you don’t register the replacement, it will toast the new battery for similar reasons to Car 1 but even worse. You MUST utilize a “conversion” in this scenario to switch the battery type. Register a replacement after that.
The vehicle must remain stationary with its new battery installed for at least 3 hours after a battery replacement. Until then, it is impossible to determine the new battery’s charge level with any degree of certainty. Possible The battery’s complete discharge-related Check Control signals are then hidden.
After a power supply interruption, some systems’ range of use may be constrained. Individual settings might also be lost.
Depending on the equipment specification, settings or activations are required. For instance:
- Autonomous engine start-stop function (MSA) vehicles: The MSA function is only operative after a learning period (the vehicle must not be awakened for approximately 6 hours).
The lifespan of a battery in these cars, whether an AGM or ordinary battery, can be significantly shortened by skipping the battery registration step. On a late model BMW, skipping battery registration can be one of the problems that results in premature battery failure. For more information, see the topic on Energy Diagnosis.
