Urgent help!!! R36 won't unlock

[Domatron]

Hey guys

I just got to the dog park and now my car won't unlock. It's a 2009 R36 wagon. It's never done this before. Unlocked perfectly 5 mins ago when I left the house. When I press the unlock key nothing happens. Even if I hold it down for a while. If I push the lock key the lights flash. The auto tailgate still opens with the key but the doors stay locked when I do that.

Is the problem my key or could it be something else?

Please help!

Thanks

Sorted. YouTube to the rescue...

Looks like the unlock button on my remote is stuffed though

Confirmed. Just got home and tested the spare key. Everything works as it should.

Does anyone know if these keys can be repaired? Or do I just have fork out for a new one?

Try a new battery in the remote.

Glad you got it sorted, but yeah; might be time to also change the batteries in both sets of keys!

[Domatron]

Thanks will give that a go

I had exactly the same issue about two months ago. I just got the spare out and I am using that now!! Might try a new battery but it is a little weird that the other two buttons work and the unlock doesn't!!

You can pull it apart and check the tactile button on the remote PCB, your key isn't really old enough for this to be broken but if this is the only button not working then this is probably your problem. replacement buttons can be bought fairly cheap and you will need to be able to solder on the new button.

Out of interest, did you try unlocking it the old fashion way of turning the key in the lock?

Yup. I always knew about the key I just never knew where the keyhole was until watching the YouTube video...

Thanks for the advice. Would I be able to get replacement buttons from somewhere like Jaycar? And if not where's the best place?

Probably but you would need to take the circuit board in to get the correct one

I have a couple of genuine Passat keys in stock, if I remember tomorrow I can pull one of them apart and have a look as I most likely have the correct buttons for them too.

Sorry for the slow reply. Attached is one of the PCB's from an OEM remote that I have, if you look on Ebay for tactile buttons you should be able to find them as this type is common.
