Technical Description and User’s Manual of the Volvo SPA Standard Key
1 General operation of the key
The Volvo SPA Key has implemented a HF transmitter. It can transmit the information when pressing a
button for locking or unlocking the vehicle by an uni-directional command via Remote Keyless Entry
(RKE) or there can be a bi-directional communication when Keyless Entry & Start functionality is requested via a LF Wake Up command issued by the vehicles antennas and the key responds in HF.
With Keyless Entry or Start the Volvo SPA Standard key reacts on a LF Wake Up-Signal from the vehicle
(initiated after activating of the sensor of the vehicle, i.e. at sensor at the door handle or the Push Start
Button, which recognizes the wish to lock/ unlock the vehicle or to open the trunk or to start the vehicle)
from the vehicle and after that the key responds in HF on the RKE frequency for authorization purposes.
When the authorization is successful the vehicle performs the desired action.
On the Volvo Standard Key there are four separate buttons, from which three of them are dedicated to
locking&unlocking the vehicle and open/close the trunk. The fourth button on the Volvo Standard key has
the functionality of activating or deactivating the “PANIC” feature.
In general the following functions are provided:
- Lock the car (Keyless Entry and RKE)
- Unlock the car (Keyless Entry and RKE)
- Open/Close the trunk of the car (Keyless Entry and RKE)
- Activate or Deactivate “Panic” feature (only RKE)
- Engine Start of the vehicle (Keyless Start)
When the battery power is too low, the key can start the vehilce with the emergency back up function via
the LF-Transponder interface @134,2 kHz (by placing it near the transponder coil located near the steering column inside the vehicle) which operates at a very short range (< 10cm).
2 Operating frequencies of HF transmission
2.1 2-channel
Two channels are implemented on the 434MHz variant (excl. South Korean variant) and on the 315MHz
variant. The following table shows the carrier frequency of the individual channels for each frequency
band.
Frequencies
Frequency Variant Channel 1 (CH1) Channel 2 (CH2)
315MHz
434MHz (excl. S.
Korea)
434MHz S. Korea
