Scroll down for the quick video tutorial or keep reading for the step-by-step guide on your BMW x1 key fob battery replacement.

Remote Key Fob Type: Non-Comfort Access
Battery: VL2020

The tools you will need:

• Flathead screwdriver/nail clippers
• A box cutter
• A desoldering iron
• A desoldering vacuum
• A solder

Step 1

Pull out the valet key from the top of the key fob.

Step 2

The next thing is to separate the key fob into two halves. To do that, look around the edges of the device, and you will see a line. What you want to do is score around that line using a box cutter. This may take you a couple of minutes to cut through the layers. Once you’re done, remove the back cover and set it aside.

Step 3

You should be holding the cover with the internal circuit board. Gently remove the circuit board and you will see the rechargeable VL2020 battery attached.

Step 4

At the back of the circuit board are two points (aka, the legs on the battery) where the battery is attached. You need to desolder them to replace the battery.

Step 5

Place your desoldering iron on each point and heat it up using the desoldering vacuum. The desoldering vacuum will suck up the solder. Doing this repeatedly will desolder the points and you can remove the two legs the battery is attached to. This process may take a while.

Step 6

Now. take your new VL2020 battery with ninety-degree offset legs and place it through the points on the circuit board (ensure the new battery is a fit for the key fob).

Step 7

Next thing is to solder the new battery to the circuit board. Turn the device to the other side and use your solder on the two points. The new battery will stay attached.

Step 8

Finally, return the circuit board to the piece of plastic and place the cover on it. Click the device together.

That’s all it takes. Told you it wasn’t so difficult.

Now confirm that your key fob is working fine by testing it on your BMW: press any button or unlock and lock your car door to see the response.
