BMW Remote Keys

Car access system

The Car Access System control unit includes the functionality of the RF remote control, the ignition and starter button, control of power at the terminals and the vehicle immobiliser. The CAS is also the gateway module between the K-CAN SYSTEM and the K-CAN PERIPHERY data buses

Bmw Keyless key

The antenna amplifier receives and demodulates the signals transmitted by the remote-control units. After signal processing, the data is forwarded to the CAS for evaluation.

As many as 4 remote-control units can be used.


The following buttons are integrated within the remote-control units:

-Deadlocking button

-Release button and/or selective unlocking of driver's door

-Boot lid button (tailgate push button)

-Interior lighting/Panic button

Each of the two remote keys contains a mechanical integrated key.

Rechargeable battery of the remote key

Depending on the vehicle equipment, an integrated rechargeable battery or an integrated regular battery provides the voltage supply of the remote key. A regular battery is fitted if the vehicle has Comfort Access (CA). In all other cases, a rechargeable battery is fitted.

The regular battery cannot be charged. The battery must be replaced by qualify auto locksmith if there is no longer any voltage supply for the remote key.

The rechargeable battery cannot be replaced individually and is charged when the remote key is locked into position in the ignition lock. A 125 kHz interface within the ignition lock executes the recharging. The rechargeable battery voltage is monitored independently by the remote key and is transmitted to the central gateway module via the data bus K-CAN


Emergency key

The emergency key is a basic mechanical spare key that is inserted into the housing of the remote-control unit. The emergency key does not include transponder functionality for the EWS electronic vehicle immobiliser.

The emergency key can only be used to unlock and lock the door locks manually in the event that the central locking system fails, etc. It can be used to unlock and lock the lock barrels on doors and tailgate as well as the lockable storage compartment. 


Spare key

A spare key with an ignition-lock adapter is also furnished with the vehicle. The spare key consists of a mechanical key bit along with an integral transponder, and is substantially smaller than the remote-control units.

The spare key offers the same functions as a remote-control unit:

-Access and driver authorisation for the vehicle

-Transponder functions for the EWS electronic vehicle immobiliser

-Individual encoding

An adapter is needed to insert the narrow, flat spare key in the ignition lock and lock it in place. Because the adapter is only required for starting, it can be stored within the vehicle.

Remote key

The functions of the central locking system remote key are activated by pressing the buttons on the remote key. If a remote key is in the ignition starter switch and the transponder is recognised by CAS, all commands from every remote key are suppressed by CAS.

Central deadlocking

When the CAS recognizes the central deadlocking command, the control module of the central locking system implements this function. The interior light is switched off immediately.

If the button is pressed again within 10 seconds the anti-theft alarm response to programming sequence the tilt sensor and interior motion sensor is deactivated. The convenience closing feature for the power widnows is the exception.

Unlocking and selective unlocking of the driver's door

If the vehicle locks are engaged, pressing the release button will disengage them provided that the CAS has not been selective unlocking. The power module activates the interior light. 

If selective unlocking has been encoded, the first time the button is pressed only the driver's door is unlocked. Pressing the button a second time unlocks the entire vehicle.  The auto locksmith  will  activate by replacement time the button is pressed.

Depending on the programmed code, it may also be possible to open the windows and the slide/tilt sunroof by pressing the button.


Boot lid/tailgate operation opening

When pressure is maintained on the button for opening the boot lid/tailgate for longer than 0.5 seconds, the boot lid/tailgate's lock is disengaged. If the vehicle is equipped with a power tailgate then the programming command that will reverse the tailgate's current status will start and then proceed for as long as pressure is maintained on the button. If the boot lid/tailgate is open then it will close; if it is closed then it will open.

The delay period between actuation and the reaction at the tailgate can be specifically encoded.

Interior door unlocking button

If the button has been assigned the "panic alarm" function then pressing the button for longer than 3 seconds will trigger the anti-theft alarm system. The panic alarm can be cancelled by pressing any of the buttons on the remote key. This deactivates the panic alarm. The button must be pressed again to execute its own assigned function.

Each time the button for the interior light function is pressed the power module switches on the interior light.


Safety smart key emergency functions

Should a remote-control smart key unit be lost, it is possible to disable it using the diagnostic interface.

First, the CAS Car Access System will need to read replacement out data from all of the remaining remote-control/key units to determine which unit has been lost. It determines which remote key is missing based on the remote key numbers that are still present.

The selected remote control/key unit can be disabled using the "Disable/enable key" diagnostic service.

Should the remote-control/key unit be discovered again at a later date, it can be enabled again using the same process.

Emergency operation

In the event of a failure in the central locking system, the vehicle can be unlocked and locked manually using the emergency key. (lock barrels on door and boot lid/tailgate as well as the locking storage compartment)
