How to Replace the Battery in a Ford Fiesta Key?
1 Answers
The car owner needs to prepare the replacement battery in advance. When purchasing the battery, make sure to buy the same model as the original battery. Then, pop out the mechanical key, locate the fastener on the key casing, and remove the outer shell of the key. After opening the key casing, remove the old coin cell battery and replace it with a new one that meets the specifications. When installing the new battery, pay attention to the positive and negative poles. Do not reverse the battery's polarity, otherwise the key will not function even after replacement.
