- 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).
