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.

Can a key fob with a low battery prevent a car from starting?
Yes, a key fob with short battery life may prevent your automobile from starting. The key fob for your automobile is an electrical gadget with a battery inside that powers signals sent from the key fob to your car. Your car’s computerized systems get alerts in accordance with the key fob commands you press, and the vehicle subsequently reacts as necessary.
This function depends on the battery in your car’s key fob; if it runs out, you might not be able to start your car without a jumpstart. Your ability to start your car may be affected if the battery in your Honda keyless remote is low.

How long does it take to charge a BMW key battery?
The EWS ring antenna from KL R charges the battery inside the key head inductively using a coil antenna included into the key. Integrated electronic circuitry in the key regulates the charging process.
- The lifespan of a vehicle is the same as the service life of a radio-control key when operated normally.
- The battery will eventually run out if the FZV keys are not utilized (i.e., kept in a drawer) after about 1.5 years.
- Approximately 30 hours are needed to fully charge a drained battery.
- After a 30-minute charging period, the remote control can be used roughly 15 times (driving time).
A transponder chip houses the important information. The transponder chip is a wireless EEPROM that may be read and written. It is powered by the steering lock’s ring coil. When the key is in the ignition switch, power is delivered electromagnetically from KL R.
Data is transferred and the battery is charged using the power supply. The transponder chip has undergone new development, enabling this.
Every time a FZV key is pressed, as in prior systems, the battery charge level is also displayed. Three consecutive low power condition messages are received by the FZV electronics before the GM sets a fault signaling a low battery in a particular key. The bus system also notifies the LCM, and an instrument cluster matrix message is sent to the driver to warn him or her.
When five consecutive messages showing a charged battery status are received, the fault will be immediately removed if the battery is recharged (used to drive the automobile).
