Compass key battery model is 3V, CR2033. Method to disassemble Jeep Compass key: Wipe the key surface clean with paper, then use a screwdriver to remove the remote cover. Gently remove the key blade, insert the screwdriver into the slot, turn it clockwise to completely separate the two parts of the remote. After removing the cover, install the new battery following the same method as the old battery. Basic principle: The key emits weak radio waves which are received by the car antenna. The electronic control unit (ECU) identifies the signal code, then the system's actuator (motor or electromagnetic coil) executes the lock/unlock action. This system mainly consists of a transmitter and receiver.
