Battery Replacement Under norlnal use, the batteries in your key chain transmitter should last about two years. You can tell the batteries are weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works,it's probably time to change the batteries. Your transmitter housing snaps apart for easein battery replacement. To open the housing: 1. Insert a dime between two halves of the transmitter housing near the key ring hole. 2. Remove the bottom by twisting the dime. 3. Remove and replace the batteries with two Duracell @-type batteries (DL2016 or equivalent), positive side down. 4. Align and snap together the back and top transmitter housings.

Your steering wheel will be locked, and so will your ignition and transmission. And remember to lock the doors. 2-12
