I can't open the back doors of my car, what's wrong with it?

The central locking on my Vauxhall Meriva isn't working. I turn the key once to unlock the drivers door and twice to unlock the back and passenger doors, however only the driver's door will actually open. I have had to put my children into the back seats through the front. Obviously it's not very safe, but I don't know what's wrong.

Likely to be sticking lock servos. There is usually an access grommet in the lock face of the door that allows you to poke the extended nozzle of a can of WD40 through and give the solenoids a squirt to drive out the moisture.
