Another key fob question

[Soetekouw]

I don't have any problem with my key fobs, but I have had my car for 4 years and I am sure the battery is geeting low.

Can I open up the fob and replace the battery (CR2032??) without losing any programming code and having to reprogram everything? Thanks.

I've replaced my battery, cr2032, without problem.
Dale K: seems your key fob has a couple of issues. If you can resolve the difference in flash frequency, you might want to try the fix I posted again. It did work for me, albeit some time ago. Both of my fobs flash normally.

OK,

Here are my symptoms, pretty similar:
Key (or better remote) started to work spotty
Sometimes it worked then it didn't
Then my first key fob stopped working altogether.
Used the 2nd key and this one started to like 6 months later.
The red lights flashes slower or not at all.
Of course I replaced the batteries etc.

At the end I bit the bullet and got one new key fob from Porsche for around $250 and that took care of all the problems. Seems like the key fobs have a limited life span. In my case it was 8 years...

new owner here of a 2008 boxter. we also have a 2000 passatt which has a similar key fob. i like the fact that the vw blade folds and is not always extended. anyone ever try a vw key programmed to the P? i need to get another key as car only had one key.
