Will This Battery Work in Your Tiguan Key?
Not every Tiguan key uses the same cell. Parts catalogues list both CR2025 and CR2032 batteries for Tiguan keys, and Volkswagen’s manual says to fit a battery with the same voltage, size and specification as the original. Run this quick check before you buy.
A CR2025 has the same 20mm width as a CR2032 but is thinner (2.5mm against 3.2mm). Never force a CR2032 into a holder made for a CR2025. The listing advertises Tiguan fitment for 2009 to 2024 only.

Tiguan Key Battery Replacement Difficulty
This is an easy job. The documented process is just opening a cover, swapping one cell and closing it again, with no programming step. Most of the effort goes into picking the right battery. Tap a slice to highlight it.
- 25% Opening the key cover
- 15% Swapping the cell
- 40% Choosing the correct battery
- 20% Checking polarity & testing the remote
The score and effort split are an editorial estimate based on the documented cover-and-cell procedure, not an official Volkswagen rating. Volkswagen recommends having the battery changed by an authorised Volkswagen dealer or service facility, and warns that changing it improperly or using the wrong battery can damage the key.
How to Replace Your Tiguan Key Battery
Tap each step to tick it off as you go.
- 1Confirm the battery typeCheck the code on the old battery or in your owner’s manual. Use a CR2032 only if your key calls for one.
- 2Open the battery coverOn a folding key, unfold the key bit and slide the back cover off in the direction shown in your manual. If your key has a removable emergency key, take it out first and follow your manual to open the cover. Some flip keys open by prising the casing apart at the hinge.
- 3Remove the old batteryNote which way it sits, then use a thin object to pry it out of the compartment. Keep the used cell away from children and pets.
- 4Insert the new CR2032Press the new cell in with the polarity matching the markings in the compartment. Do not assume which side faces up on every key.
- 5Refit the coverPlace the cover back and press it down until it clicks into place.
- 6Test the remotePress lock and unlock near the car to confirm everything works.
Recheck the battery type, polarity and seating, and make sure the cover is fully closed. Obstacles, bad weather and nearby transmitters on the same frequency can also block the remote. If the problem continues, the Tiguan owner’s manual has a separate procedure for synchronising the key.
Other Devices That Use a CR2032

Tiguan Key Battery: FAQ
What battery does a Volkswagen Tiguan key use?
It depends on the key. Parts catalogues list both CR2025 and CR2032 for Tiguan keys, so check the code on the old battery or your owner’s manual before buying.
Can I use a CR2032 in place of a CR2025?
Not as a general rule. Both are 3V and 20mm wide, but a CR2032 is 3.2mm thick and a CR2025 is 2.5mm thick. Volkswagen says to fit a battery with the same voltage, size and specification as the original.
Does this pack fit every 2009 to 2024 Tiguan?
The listing advertises that range and asks buyers to match their key to the pictured fitment guide. That is a fitment claim, not a guarantee for every key. Confirm your key takes a CR2032.
Is the Deluxe CR2032 rechargeable?
No. It is listed as single use, and a CR2032 is a non-rechargeable lithium coin cell. Never try to recharge it.
Do I need to programme the key after changing the battery?
The documented battery change does not include programming. If the remote still does not work, the Tiguan owner’s manual has a separate procedure for synchronising the key.
Do both batteries in the pack go into one key?
No. A Tiguan key takes one button cell. The pack holds two separate replacement cells.
How long will the battery last in a Tiguan key?
No reliable runtime figure is published for this pack. Life depends on how often you use the remote functions and on temperature.
How should I dispose of a used CR2032?
Tape over the terminals straight away and take the cell to a battery collection centre. Follow your local disposal rules and keep used cells away from children.
