How to replace a car key battery?
Replacing a car key battery is usually quick and simple. Most fobs have a small slot where you can gently pry open the casing with a flat tool or coin. Once it’s open, just pop the old battery out and slot the new one in, making sure the positive and negative sides are the right way round. Close it back up and you’re good to go.
