There is a tiny screw by the attachment to the key ring. Walmart had a small enough screwdriver to open it and slide out the battery and replace it with a new one.
If you take your key an press firmly on the Saab emblem while at the same time pull on the very top of the key, the metal key will pull out an u can unlock the doors or truck if need, the car will start with a dead battery in the remote key
Remove the metal key from the 2004 vw remote. There should be a small place under the key to push to open the case, and replace the battery.
You hold down the Saab logo and pull the end of the key fob so the actual key comes out. Then inside there is a small rectangle, you use that key you just pulled out to use as a lever so the two pieces of the key come apart, it is a really easy task, you will see the battery and you will know exactly which kind of battery to buy.
There is a small hole in the side of the key head. Insert a paperclip into the hole, and pry the back off.
Call a locksmith.
I work on Saab's another Swedish car. i have seen something simler,basically the security control module doesn't recognize the key. On Saab their is something called a transponder inside the key itself(inside the handle-the part you hold)its a electronic chip no battery needed. your best bet is to take it to the dealer for reprogramming. If by some chance their is a remote built into your key you might want to replace the battery first, then check your owners manual to see what they say on key fob battery replacement, you probably got to stand next to the car and push one of the buttons a few times to get it in sync with the car.
put new battery in
There is no battery inside the key to replace. The key actually charges through your ignition. If its not functioning you will just have to order a programmed key from the dealership.
From SAAB., Your nearest dealer can get a key to match your barrel.
