My car (an Audi) after 9 and a bit years has decided it can't be bothered to take any notice of it's remote key locking, unless I actually put the key in the door lock and turn it. If I do this, then everything is fine for a few minutes and then the said car becomes all uncommunicative again.
What's that all about?
RTFM reveals nothing relevant to this problem.
Grrrr! 😆
Alarm or locking ?
If the car alarm becomes unsync'd with the key fob, you need to do something like arm (or de-arm) the alarm via the fob whilst the key's turned in the *ignition*. Or something like that...that *is* in TFM, tho' - but mebbe not be the problem you've got..
The locking and the setting of the alarm occur simultaneously.
The problem is the car won't respond at all.
I hate to point out the patronizingly obvious but have you got a battery in the keyfob. After nine years might be flat!
I don't know much about it but I believe the keys are more than just keys. Mine is the immobiliser as well. If the battery is flat the car won't work!
The batteries in the keys have been replaced and this happens with both sets of keys in any location.
I am unocking the driver's door, putting the key in the ignition and swithcing on, then pressing the unlock button, removing the key. I think this might be wrong, but the manual is rather vague about the task. After doing this. all then works fine, but only for a few minutes.
The vehicle's battery has a good level of charge.
This appears to be some sort of electronics issue within the vehicle.
Is there anyone with direct expereince who can fill me in? Thanks in advance!
Is there an independent VAG specialist near you you could contact?
You may find it's a well know fault with a (possibly) simple and inexpensive solution if you give them a ring
My Passat needed recoding as a key kept forgetting how to operate the central locking, though it worked fine in starting the car. The independent VW specialist charged me a tenner to reset, and it's been fine since.
This may work but no guarantees.
