GF80.61-P-0005LE Keyless-Go, Function
- with CODE (889) Keyless Go


Keyless-Go (KG), general
The Keyless-Go system allows access to the vehicle and starting the vehicle engine without using the transmitter key (A8/1). It is sufficient to just carry the transmitter key

Operation of the central locking (CL) via the transmitter key remains possible parallel to the Keyless-Go functions. The anti-theft alarm system (ATA) (with code (551) Anti-theft alarm system (ATA)) functions in the same manner as when locking/ unlocking the CL with the transmitter key.

The Keyless-Go system comprises the following partial functions:
^ Function sequence for position definition of transmitter key
^ Function sequence for locking/unlocking:
^ Function sequence for engine start/stop

The following partial functions are described in separated documents:
^ Locking/unlocking, function
^ Engine start/stop, function

Function sequence for position determination of transmitter key (on model 216)

A position determination of the transmitter key is required for the individual functions. When the
- Trunk KEYLESS-GO antenna (A2/35),
- Left door KEYLESS-GO antenna (A2/39),
- Right door KEYLESS-GO antenna (A2/41),
- Center console KEYLESS-GO antenna (A2/60) and
- interior Keyless-Go antenna (A2/61)

are activated by the Keyless-Go system, the transmitter key can determine the area (A, B, C, D or E) in which it is located.







Function sequence for position determination of transmitter key (on model 221)

A position determination of the transmitter key is required for the individual functions. When the
- Trunk KEYLESS-GO antenna (A2/35),
- Left rear door KEYLESS-GO antenna (A2/39),
- Right rear door KEYLESS-GO antenna (A2/41),
- Center console KEYLESS-GO antenna (A2/60) and
- interior Keyless-Go antenna (A2/61)

are activated by the Keyless-Go system, the transmitter key can determine the area (A, B, C, D or E) in which it is located.







The determined position is transmitted by the transmitter key via radio signal. The rear window antenna amplifier module (A2/12) edits the signal and relays it to the KEYLESS-GO control unit (N69/5).
