Central locking on my passat 05 only opens drivers door when using key fob have to use button on door inside car to open rest

I'm guessing this is a safety feature so you don't get car jacked. Try pressing the button for longer. Might even be a child lock feature, check child locks.

Check your car setup. Read the manual on MAXI DOT and look for Main Menu > Settings > Comfort > Central Locking. Within the Comfort menu you can also reset to factory which should set central locking to automatic.
I hope this helps.

usually if you unlock the drivers door twice it will unlock the other doors.

turn key twice when opening, ie turn right. once drivers door will unlock, turn twice passengers doors will unlock, and locking is turn anti clock wise once will lock all doors, turn twice will set door dead locks.dead locks will stop openand lock internal button working and handle from opening door. the same actions can be applied to the remote one press drivers door, two press passenger doors, press and hold unlock button for 5 seconds and rear window will open.

I have this on a Passat 1998 model and it's frustrating, im at the point where all 4 doors wont unlock and the 2 front ones work with the key but need to be closed with the key again.The boot opens and closes with the remote.I removed and cleaned all four door barrels when they opened intermitently and under the passenger side footwell is the ecu for the windows&alarm which i removed and cleaned as well as soldered 2 dry joints.If i activate the fob i hear the relay in the ecu click and double click to lock and the boot lock works which indicates the electrics are ok.Doing a google there are 1000sssds of queries with passat/vw door lock problems and the main cause is dry solder joints in the door lock mechanisms in the door.I found out from the main dealer when replacing my bootlock(the old one was damaged in a theft attempt) that a new modified part was available and the same for door locks????leading me to believe this is a widespread problem.The only thing is to remove the door parts and inspect the catch and circut board for dry joints.This link may help you. http://forums.vwvortex.com/zerothread?id=1542461 copy and paste this into your browser or google the website if you dont know how.

hit the unlock button twice. most fobs are programmed so you hit it once, drivers unlocks, and again for all the rest.

My 1998 passat done the same, try remove the drivers side window/childlock control on the armrest and clean the multipoint switch as that got my drivers side door opening/closing on the fob as well as the passenger rear door unlocking and working again as it was deadbolted and would not open inside or out.

Was it working before and it just stoped working? Either its not programed to the vehicle or the unlock button is bad. the buttons do wear out over time.

You have the wrong KEY if it won't turn any locks.
You can use the KEY fob from another Passat.
The one you have was most likey not the original
and the car was reprogrammed to except that FOB.

The Fuse panel Is inside the DRIVES side.
Open the Driver door. Look at the side of the DAShboard.
THat Giant "B" Shapped plastic cover pops off.

Check the fuses...IF any are broken,black or no good.
REplace them

if your unlocking the doors with a key and the engine is starting it wont have a key fob,if your opening the doors with the key and the alarms going off and it wont start then it will have a key fob
