BMW 3 Series key battery replacement

Model: BMW Serie 3 E46 - Years 1998-2006
Part: Key

Let's see in this guide how to disassemble and replace the battery of the BMW 3 Series key, but also of the Z4. First of all, we take our key in hand and start to pry on the small lateral crack, using something thin, in order to open our key in two parts; then we remove the small battery from the electronic board, trying not to damage the contacts of the latter, as shown in the video. At this point we install the new battery, of the right type (in this case a LIR 2025); we just have to assemble our key again!

How to Remove the Brake Disc on Mitsubishi Pajero

How to remove the brake disc along with the brake pads on a Mitsubishi Pajero? First, lift the vehicle on a column lift to a suitable height for working. Next, remove the wheel (using a telescopic spanner or air drill) with the respective bolts. Undo the locking bolt of the brake caliper, and remove it from the caliper support. Remove the caliper support from the wheel hub using a socket spanner. Once the brake disc is free, undo the screws with a fixed spanner and detach the disc from the wheel hub. Disconnect the various wiring and brake fluid pipes from the wheel assembly. Replace them with new parts (always use original and compliant parts). Prepare to install the new disc along with the respective pads, brake caliper, caliper support, etc.
