Default Keyless start

Twice recently my wife has gotten in the Q and she could not get it to recognize the key was in the car and she had to use the key to actually start it. Has anyone else ever had that problem or have a suggestion? She has gotten out of the car and gone back in the house and tried again and it still won't recognize it.

Default Maybe the battery in the key is low. Anyways, best chance is take it to the dealers. Something

like this would be covered under warranty. If it is a battery problem, and you ask them to change the battery out, they will charge you big money for it.

Default I had the same problem. dealer changed batteries for my 2 keys

the voltage of key should be more than 3.2v.

My old key batteries are 2.8v and 2.6v. after batteries changed, it goes back to normal.

Default X 2. We had the same problem. After replacing the main antenna it worked fine. Just recently.......

the rear passenger door will not let you arm the alarm by pressing the buttom so I ran the VAG-COM on it and sure enough a fault code came up. The antenna in that door is now bad. Going in for the 15K service in a few weeks and will get it fixed then.

Default How long did they last.

Were you surprised by them being dead?

I am just curious to know the approximate life span of advanced/Remote Key batteries though I suppose it varies by the amount of entries/mileage as much as time.

It looks like the battery in the remote died today.

Default 1 year battery life span.

battery was not 100% dead but you start experiencing requiring few times to open a door or car start telling key is missing once in a while.
