Central Locking Not Working Right

[BRENDAN1]

my 2000 avensis 1.8 se key had a flat Battery i changed it and used the internet to find how to get the key fob to lock and unlock the car. this worked for two days now the central locking will lock the whole car but will not open all of the car it only opens the drivers door. Even putting the key into the door to unlock all the doors will only open the drivers but will lock all the doors ok. we have to unlock passenger door and back doors manualy. can anyone give me ideas on what might be wrong with it.

Hi,

What did you find on the Internet, in addition to just changing the Battery in the key fob, after which it should be working as before?

I used the internet to see how i could get my keys central locking to work to lock the car left drivers door open key in ignition and pressed the unlock button twice this worked but now has stopped for some unknown reason and will lock whole car but only open drivers door, this is the same when you put the key into the car door will lock all the car and only open driver door
