Video tutorial

On the Peugeot 308, the remote control battery is changed by opening the key without damaging the plastic, so the first step is to work calmly on the body of the key. In the video, it starts by removing the emergency metal key: once freed, the slot where leverage is applied to separate the two halves of the shell becomes visible.

At this point, still on the Peugeot 308 key, a small flat tool is inserted into the gap and a slight twist is made to open the casing.

The shell separates, revealing the internal part, where the battery compartment is visible. The battery is lifted from its seat and replaced with a new one, being careful to place it in the same position as the old one. Once the replacement is complete, the Peugeot 308 key is closed by aligning the two halves until they snap back together, then the metal key is reinserted into its housing.

Finally, it is checked that everything is stable and that the remote control buttons are free and do not get "stuck.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
