As the sole driver of my vRS , I only use one of the 2 supplied remote key fobs; one I use daily, the other is now buried in the depths of my desk. As long as the battery does not go flat on the unused one, does anyone know if this spare one will continue to work after several months of laying about? I'm assuming here that they use a 'rolling' code, and if they do, how does the idle one keep up with the one in daily use?

I didn't use my spare for a few months, then the battery went dead on the main fob. Worked fine. I'd guess at maybe 7 months mine went without use?

The car keeps track of the two keys separately. They each have their own rolling code.

I used my first until the battery went flat after around a year, then moved on to the second. The first still works as I needed it yesterday because I locked the keys in

I heard that once the battery goes completely flat, then the key needs to be reprogrammed by the dealer, at a cost of some

I'm not so sure if that 15 second rule is the case. When I bought my car, one of the fobs didn't work, so as part of the deal (I bought it s/h), I asked the guy to get a new battery in the fob (it was an independant garage, not a Skoda dealer). I can't imagine he would have taken the key to a main dealer, nor ensured that he spent no longer than 15 seconds on the battery? Besides, I would assume that since the fob was lifeless when I first tried using it, the battery had been totally flat for a while?

i too am the only driver of my skoda but i rotate the keys weekly as i did with my previous car

I'm sure Lummox could have answered this :bigcry:

It's a good question and an answer that could affect us all, we NEED to know!

I just changed the battery in my Passat 1.8T the other week. It took me way more than 15 seconds, more like 5-10 minutes and there was no problem with the remote keys after that. I can't imagine there would be any different with a Skoda

Right, you meant the battery in the key.... Never mind

I've changed the battery in my fob lately, worked fine with a battery from Tesco.
