First of all disconnect the battery for 30 minutes. This might reset any electronic glitches.
If you apply about 1 bar of air pressure to the PSE air lines, this will be enough to actuate the components on this line.The central locking lines should be marked with ZV at the PSE or are yellow.
Check the batteries in the key- they are used only for central locking signal.
Check if the central locking is working from the interior pushbutton.

Best regards,
