Fault in Open&Start system or radio
remote control.
If the central locking cannot be operated or
the engine cannot be started, the cause
may be one of the following:
z Electronic key out of reception range, or
out of range of radio remote control,
z Radio remote control battery voltage too
low – see previous page for instructions
on how to change battery,
z Frequent, repeated operation of the
radio remote control outside the
reception range (e.g. too far from
vehicle, remote control is then no longer
recognised).
z If the central locking system is
overloaded as a result of repeated
operation at short intervals. The power
supply is cut off for a brief period.
z Interference from higher-power radio
waves from other sources.
Keys, doors, bonnet
To remedy the cause of the problem, move
electronic key or radio remote control to
another location or change the remote
control battery. If the problem persists we
recommend that you consult your Vauxhall
Authorised Repairer.
