my 2006 vauxhall vectra has no door locks and battery is dead how do i open the doors ?

There MUST be a VAUXHALL trouble line to tell you! TO BAD the OWNER';s manual is INSIDE THE CAR then! TRY calling the PARTS DEPT at a VAUXHALL dealership near YOU! BYE NIOW and GOOD LUCK. You may have to uise a CLOTHES HANGER to get the hood open! GOOD QUESTION!  CALL THE DEALERHSIP for HELP! By CALLING the dealership they may EVEN be able to open it from a SATELLITE< but MAINLY find a way to OPENTHE HOD 

have to give it a 'jump' ................................

Apparently, YOU don't.

look for a tutorial on youtube

The fob has a hidden key.  Use the key to open the hidden key slot in the door handle.

Get a locksmith to open the doors then change the battery. If you're a member of the AA call them out because they have ways of unlocking your car.
