Introduction
Go to step 1 ↓If the key fob for your 2018 Jeep Compass stops working, it is more than likely time to replace the key fob battery. This is something that does not require much skill or time.
Most vehicles have key fobs for many functions of a vehicle, such as starting the vehicle, locking and unlocking a vehicle, lifting the trunk, and emergency panic alarm.
Key fobs typically need a battery replacement after a year or two of everyday use.
