key battery

[djomlas]

when i got my car the key wasnt opening the doors...changed the battery and put the key in ignition, turned all the way without turning the car on, took it out, pressed the button and worked fine. that was about a month ago. last week for soem reason it stopped again, was blinking and everythign but nothing was happening, and then today no light at all. bought a new battery and now it works again.
what would make the life of battery last only 1 month?
any thoughts?

i had the same problem in my 2003 audi a6. it seems there was a batch of defective keys which kept draining the batteries. check with a dealer or search for a tsb re:key defects.

The remote sensing in the car turns off after a couple of weeks to save battery life. You have to turn the ignition on to reactivate it. Maybe that's what you're experiencing?

Mine's a 2002- 3 weeks of life for mine.
Can't be...
I'll be doing a search on defective keys. That wouldn't be good.
btw Mine's never opened either trunk, although at times I do hear some faint clicking when I press the button.

How long should the battery last anyway?
