How to Replace the Battery in a Toyota Prius MK2 Remote

Model: Toyota Prius Xw30, MK 2 - Years 2009-2015
Part: Key

Let’s see how to replace the remote battery for the Toyota Prius MK2: no special tools are required, just the new CR1632 battery which can be found at any electronics store or supermarket (as well as online). First, extract the mechanical key by pressing the side button on the remote, then insert the tip of the mechanical key into the side slot and pry to separate the two halves of the casing. Once opened, remove the circuit board and use a small screwdriver to pry out the battery from its housing. Place the new battery in with the positive side facing up, replace the circuit board, close the two halves, and test the operation.
