To replace the battery, carefully remove the case screw located at the end of the
remote transmitter where the key ring attaches to its case. Use a small blade
Phillips screwdriver. Before removing the battery note the direction of its
terminals. Install the new battery exactly the same, using caution so as not to
bend, or otherwise damage the battery contacts. Replace the case cover and
carefully tighten the screw. Do not over-tighten the screw. Test the transmitter
to be sure it arms and disarms the alarm.
