2012 Jetta Key Fob
Press Silver Button
Flip Out Metal Ignition Key
This automotive maintenance tutorial was specifically written to assist owners of the 6th generation MK6 (2011, 2012, 2013, 2014, 2015 & 2016) Volkswagen Jetta in changing the battery in the key fob remote control for the keyless entry system.

Owners of other VW Group vehicles with similar key fobs such as the Passat, CC, Tiguan, Golf, Touareg, Beetle, GTI, SportWagen, Eos, Rabbit, Bora, Vento, Audi A3, A4, S4, A6, S6, A7, A8, Q5, Q7, A5, S5, and TT may also find these DIY instructions to be helpful.

A replacement "coin" cell (A.K.A. "button" or "watch") battery is part number CR2032.

They are available from various manufacturers such as Panasonic, Energizer, Sony, GE, Maxell, Philips and Duracell.

No tools are required to replace the battery.

A small flathead screwdriver may be useful for prying out the old battery.

Thumb In Slot On side
Pull Off Battery Cover
Old Battery In Socket
The first step is to press the small round silver button at the top of the key fob to eject the flip out or "switchblade" style metal ignition key.

Turn over the key fob so that you are looking at the back side and locate the rectangular cover on the bottom half.

Place your thumb inside the void on the side of the fob where the metal key used to reside and gently pull off the rear cover.

Pop Battery Out of Holder
Old CR 2032 Battery Removed
Slide In New CR2032 3V
Either pull out the old battery with your fingernail or carefully pry it out with a small flathead screwdriver.

Slide a new CR2032 3 volt coin cell battery in to the socket with the "+" positive side facing up towards you.


"+" Positive Side Up
Line Up Rear Battery Cover
Push Battery Cover In Place
Make sure that the new battery is fully seated inside the fob.

Line up the rear cover over the fob and gently push it down in to place.

Cover Flush With Fob
Close Flip Out Ignition Key
Test New Fob Battery
Check that the rear battery cover is flush with the rest of the fob on all sides.

Swing the metal ignition key back in to the fob to make sure that it closes properly.

To test the new battery, stand near your Jetta and press the "Lock" or "Unlock" buttons. If the new battery is working properly, you should see the parking lights flash and hear the door locks opening or closing.

Be sure to write down the battery change in your vehicle's service records.
