How to replace the battery in the Lexus RX key remote.

Model: Lexus RX MK 3, Al10 - Years 2008-2015
Part: Key

Today's instructions will show us how to disassemble and replace the battery of the Lexus RX key remote. First, let's take our remote and start by removing the physical key from inside it; we can use the slot created to pry open the remote into two parts, thus accessing the circuit board and the battery, as shown in the video. At this point, let's remove the old battery and replace it with a new one of the correct type (in this case, a CR 1632 3V); we will insert it in the correct orientation and reassemble the two parts of the remote!

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
