Replacing the battery in a Saab alarm is necessary from time to time. If you are having a hard time locking or unlocking your vehicle using the remote keyless entry remote, the most likely culprit is a dying battery. Thankfully, replacing the battery in an alarm remote is an easy process, as long as you have the right tools and battery on hand. The procedure for changing an alarm battery varies between Saab models, so be sure to follow the instructions unique to your model.

Find the right battery. The size of battery used is stated in your owner's manual. Alternatively, a dealership may look up the correct battery size and give you this information over the phone or in person at the parts department.
Open your key. The procedure varies from model to model, but all will require a small flat-tip screwdriver to pry the remote open. If you have a first-generation 9-3 (from 1998 to 2002), your alarm remote is a separate dongle that hangs from your key chain. Pry the remote apart at the seam near the bottom.
If you drive a second-generation 9-3 (from 2003 to present), opening the key requires an extra step. Press the griffin logo on the back of your key and pull on the key chain rang on the top. This will release the emergency door key from the remote control. Once the key is removed, use a flat-tip screwdriver to open the remote.
On all 9-5 models from 1999 through 2009 and 9-7X models from 2005 through 2009, the key and remote are integrated in a common unit. Look for a small opening that allows a screwdriver to be inserted, and use this to pry the key open.
Replace the battery. With the remote opened and the battery visible, you should be able to remove the battery with your fingers. If the battery is too far down to reach or corroded in place, you may use your small flat-tip screw driver to break it loose. Insert the new battery in the same orientation as the battery that was removed.
Reassemble the alarm remote. Make sure that the remote or key snaps back together properly, or it could unexpectedly come apart while you are driving or carrying it. Once the key is reassembled, test it for proper function. If the alarm and remote keyless entry features are not working, check to make sure the battery is pushed in firmly.
