Replacing the Remote Battery for Ford Focus, C-Max

Model: Ford C Max MK 1 - Years 2003-2010
Part: Key

In this video tutorial, you will learn how to dismantle and replace the battery in the remote control of a Ford C-Max, as well as other Ford models like the Focus. First, take your remote control and detach the back by prying it open; then remove the key by pulling it out. Using a screwdriver or something sharp, remove the cover by prying it off and separate the remote into two parts. At this point, you will have access to the battery: remove it and replace it with a new long-lasting one. It is recommended to clean all electrical contacts in the meantime!

How to change the time on a Toyota Yaris

In this video we see how to change the time on a Toyota Yaris, specifically when it comes to switching from daylight saving time to standard time and vice versa. We go to the multifunction screen and press "settings": from there we go to press the clock, simply click on daylight saving time, and the clock will change the time for us, without doing anything else. All we want to do is just adjust the time format to 12 or 24 hours, as is customary in the area where we live: for example in Anglo-Saxon countries it is common to set the time to 12 hours, while in the European Union it is normally set to 24 hours.
