Operation: How to replace the key battery of an Audi A4

Before we can start, we will have to go and press the button located in the upper section of the key of our Audi A4, to then extract and remove the physical key from inside the electronic key. Let's start by going to disengage and extract the battery section of the key. By doing so, we will have reached the exhausted battery. We then proceed by going to disengage it from its housing. When we have completed this last step, we will be able to completely remove the battery, and we will have finished the disassembly. To mount the new battery and close the key, all we have to do is follow this short procedure in reverse, and we will have completed the replacement.

How to open the bonnet of the Volkswagen Polo

Let's see in this short and simple guide the instructions that will allow us to open the bonnet of the Volkswagen Polo. First of all we open the front door, on the driver's side, and start pulling the opening lever of the engine hood, in order to open the lock; then let's move to the front of the vehicle and unhook the tab that we find on the central part, above the manufacturer's emblem, as shown in the video. At this point we block the bonnet with the lateral rod; then we accompany the bonnet down to close it again!
