Hi all

I have recently purchased an 04 Passat from a non VW dealer.

I have been supplied with 2 infared key fobs.

One of the fobs works perfectly, the other will do everything except unlock the car using the unlock button. The faulty key will unlock / lock the drivers door and start the car so it appears to be programmed ok,

I have looked at key fob threads on here and tried re-programming without success.

So would a low battery do this?

Does anyone have any ideas?

Many thanks.
