Remote fob eats batteries

[chrisa72]

I have an 02 Boxster S. When I purchased the car three years ago, one fob worked the other didn't. I replaced the one that didn't and it works fine. The one that did work has become unreliable and only works intermittently. I have discovered that when I replace the battery in the fob, it works perfectly and from a good range but the performance tails off over a couple of days. It is as though there is a current drain taking place within the pcb of the fob itself. For when I put another new battery in the fob, the same cycle happens again. Secondly I am able to program the memory of the electric seats to the key that doesn't work very well but not to the new one. I have tried all the usual recommendations like putting the key in the ignition, turning it on and pressing the remote button etc. Doing the same in the door lock as well but I have a feeling that it is the fob itself that is shot and I have to position myself over the barrel for another shafting from my dealer!

You don't have a sticky button do you? like the trunk or something you might not notice". I'd take it a part, look for corrosion, a bent contact moisture, etc. There are no moving parts except the battery contacts and the key stem if its loose.

I agree with pk2 likely a worn out button or stuck button.

Member Tool Pants posted a picture a few years back of the inside of a key fob where you could see the buttons were worn and deformed.

A good fix is to buy one of those nice Design Keys and transfer your immobilizer pill to the new key.

Hi. I have been having the same issue with my key fob - 996 911TT. I would put in a new battery and within a couple of days the battery would be dead. I tried different batteries with the same result. I too thought the old fob buttons were a problem and bought a new fob and used the old fob board in the new fob housing. And sadly the same result - dead battery within a couple days. There doesn't seem to be any follow up. Was there a fix??? thanks
