This automotive maintenance tutorial was specifically written to assist owners of the first generation (2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 and 2017) Volkswagen Tiguan SUV in changing a dead or weak battery in the key fob remote control for the keyless entry system.

Owners of other VW or Audi vehicles such as the Jetta, Passat, CC, Atlas, Touareg, Golf, Beetle, A3, S3, RS 3, A4, S4, A5, A6, S6, A7, S7, RS 7, A8, Q3, Q5, TT and Q7 may also find these DIY instructions to be helpful.

The compatible replacement coin cell (A.K.A. "button" or "watch") battery is part number CR2032 3V Lithium which is available from various manufacturers such as Panasonic, Sony, Duracell, Energizer and Maxell.

No tools are required to access and replace the battery.

Release Metal Ignition Key
Void On Left Side
Pull Off Battery Cover
The first step is to press the chrome silver button on the top left of the fob to release the switchblade style metal ignition key.

Then insert your thumb into the void (opening, notch, space) where the metal ignition key used to reside.

Battery Cover Removed
Old Battery In Socket
Pry Out Old Battery
Firmly pull open the back cover on on the fob in between the VW logo and the silver metal key ring loop on the bottom.

Set the rear cover aside in a safe place.

Either turn over the fob and gently tap it on the table to dislodge the old battery or use the flathead screwdriver to pry it out.

If you use the screwdriver to remove the old battery, avoid damaging the metal electrical contacts or the green plastic circuit board below it.

"+" Positive Side Symbol
Push In New Battery
New Battery Installed
There is a "+" symbol on the battery cover to indicate that the positive "+" side of the battery should be facing up towards you and the "-" negative side should be facing down into the socket.

Push a new number CR2032 battery into the holder with the blank "-" negative side facing down.

Make sure the new battery is securely in the socket.

Line Up Rear Cover
Snap Cover In Place
Test New Key Fob Battery
Line up the battery cover over the back side of the fob housing.

Pop the cover back into place.

Make sure the cover is securely in place and flush with the fob at every edge.

To test the new battery, stand near your SUV and press the "Unlock" or "Lock" buttons on the key fob.

If the new battery is working properly, you should see the parking lights flash and hear the door locks opening or closing.
