Synchronization of Ignition Keys With Radio-Frequency Remote Control

Synchronization Of Ignition Keys With Radio-frequency Remote Control

Synchronization is necessary when vehicle does not open or close when radio-frequency button is operated or when relevant malfunction is indicated in Read measuring value block function. It is possible that key code and control module code no longer match. This can occur if send button on key is operated frequently outside operational range of system.

vehicle key(s) must be re-synchronized if this occurs. synchronization procedure must not last longer than 1 minute.

- Operate either unlock or lock button on radio-frequency key to be synchronized one time for approx. 1 second.

Central locking system does not react. A valid fixed code is detected however and variable code word is stored.

- Within one minute, unlock or lock vehicle mechanically once using radio-frequency key.

key is recognized as a valid mechanical code. A new variable code is established between control module and key. Synchronization procedure is completed.

- Perform function test of radio-frequency key.
