How to change battery in key fob Dodge Journey?

Dodge Challenger key fob replacement is not too difficult but straightforward and easy. All you need is a new battery and a small flat blade screwdriver.

First step: Remove the emergency key from the key fob by pressing down that small sliding button to release the metal key.

Second step: Insert the tip of the small flat blade screwdriver in the slot where the metal key was and twist it gently to pry apart the key fob.

Be careful not to scratch the two halves of the key fob, and do not bend them too much since they are fairly fragile. You can use a shim or another small piece of flat metal if necessary in order to get enough leverage on the screwdriver for prying apart the key fob housing.

Third step: Remove the old battery carefully with the help of the screwdriver. Dispose of the old battery properly.

Fourth step: Insert the new battery in place and gently press it down. Be sure that you follow the correct battery orientation when replacing the battery.

The Dodge Challenger key fob uses a CR2032 3V Lithium Battery. This battery type is easy to find at any local store that sells batteries. You might have to remove a small adhesive label or plastic protector so it can fit into the key fob housing without interfering with other components inside.

Fifth step: Carefully put back together both halves of the key fob until you hear them click firmly in place again. You should be able to fix this without any tools or extra force, but if you feel that it resists too much, then stop and check the battery orientation again.

Sixth step: Return the mechanical key back by sliding it to its original position and make sure that it locks in place.

And the last step: Test the new battery by pressing any button on the key fob while holding down the lock/unlock buttons simultaneously for at least three seconds until you hear a beep or see lights flashing. This means that your 2020 Dodge Challenger Key Fob is working properly.
