How to fix unlocking option key fob?

[jagjot]

I have vw polo 1.6 16v gti, MKV, year 2000.

I recently got my key fob configured to unlock and lock the car.

But for some reason when I try to un-lock my car. I have to press multiples times. on an average 5 to 7 times. Every time I click unlock my cars indicator flash but doesn't unlock.

Any Ideas?

Check your central locking pump, it could be leaking as its a pneumatic system. It lives behind the drivers side tail light in a polystyrene cradle.

Thank you... I bought used pump from scrappy and changed it still door unlocking not working properly. also noticed when clicking unlock button lights are flashing but pump is not making any sound (means not even starting / trying to unlock)...
any more ideas?

Does the car unlock alround when you physically use the drivers door lock or has your central locking failed period? I'm just going through a process of elimination.

yes, if use key car unlocks an locks fine.
with the fob locks fine only unlocking has a problem.

Is this with both keys or just the new one? If it's the new one only it sounds like a dodgy button on the fob.

I just have one key.

earlier I was only using key to unlock and lock the car.

It sounds like a problem with the key. If it locks first time every time the receiver in the car must be ok.

Hi Folks,
I bought a brand new fob from vw garage and got it configured again to my car. but still locking is working fine and unlocking blinks lights but - only unlocks after few unlock button clicks.

Looks like car is receiving the signals but pump is not getting the current first time (only after few clicks).

any more ideas?
