How to install a new battery in the Subaru Impreza “Silver Sides” key fob
Total Time: 4 minutes
1. Remove valet key from back
Flip the key to the back. Search for and press the small button behind the key and pop out the valet key.
2. Use screwdriver to open battery cover
Insert a flathead screwdriver into the slot beside the valet keyhole and twist. The battery cover will come apart in halves as soon as you twist.
3. Work with circuit board half
After opening up the remote, one part has the circuit board. Set the first half aside as you are going to be working with the half that houses the circuit board.
4. Flip circuit board, remove battery
Gently remove the circuit board from the back casing and flip it over. The other side of the circuit board houses the dead battery. Hold down the board with one hand and use the flathead screwdriver to reach into the space between the plastic housing and the battery with the other hand. Insert and twist the screwdriver into the space until the battery pops out.
5. Insert new CR2032 battery, positive side up
Install the new battery into the battery hole with the positive side (the part with texts) facing up. Push the battery down towards the bottom first and click the top.
6. Reattach circuit board, ensure battery fits
Return the circuit board to the back cover. Ensure that the battery sits in the battery-shaped hole on the back cover.
7. Reassemble halves, replace valet key
Place the two halves back together, but be careful so that the plastic on the other half does not fall off. Click the two halves and they’d snap right into place. Finally, replace the valet key.
There you go! Start enjoying your remote keyless entry again.

Tools you will need:
- 1x CR1620 battery
- Flat-head screwdriver
Get a small flathead screwdriver. Insert the screwdriver into the top of the key where the key ring attaches. Once you get enough space, use the screwdriver to work your way around the key and split it into two halves.
After the back casing comes off, you’ll see an internal piece. The inner piece houses the battery. Remove the internal piece and set the casings aside.
Now, put a flat-head screwdriver under the latch at the top of the inner piece and push it up. Repeat the same for the second, third, and fourth latches until you can easily pull the inner piece apart with your fingers.
Put the corner of the flathead screwdriver under the battery hole and carefully pry the old battery out of the inner piece.
Swap the old battery with a new one in a reverse order i.e with the positive side (the part with lettering) facing down. Click the battery into place with your finger.
Click the internal piece back together by pressing them against each other slightly. Carefully place the inner piece back into the fob case with the buttons away from you to fit into the casing. Finally, replace the second cover of the fob key.

Frequently Asked Questions
When should you replace the battery in your Subaru key fob?
The batteries in a car key fob should last for three to four years under normal conditions. As a bonus, there are a few telltale indicators that the fob’s battery is about to die. Lower than usual signal strength is the first warning indication. Most key fobs today can communicate with a car up to 50 feet away, but this will be almost impossible when the remote battery is low.
Will the car stop if the battery in the key fob dies?
Nothing will happen if the battery on your key fob dies while you’re driving. Since the key fob just functions as a door unlock and engine starter, the vehicle will continue to function normally. The keyless remote does not affect the car’s ignition or engine once it’s in motion.
What kind of battery does a Subaru Impreza key fob take?
The Subaru Impreza key fob battery varies. Some Subaru Impreza key fobs use the CR 2032 battery model, some use the CR2025 batteries while others use the CR 1620 battery model. Save yourself the stress of searching for a store or dealer of a quality brand of any of these batteries by buying on Amazon. You’d not only get the best brand, but you’d also get the best price and value for your money when you buy the batteries on Amazon.
Sometimes, you’d discover that unlocking is delayed and your driver’s headlight won’t flash when you unlock the vehicle. The general functioning of your key fobs will not work well if the remote battery is low. You will realize that waiting till your keys fail you before getting them replaced is not going to be as easy as you think.
It is best to not wait until the battery has died before replacing it. The key fobs will send a message to show you that is time to change the old one. Pay attention to your car, do not ignore the warning signs.
Follow the simple steps in this post and replace your fob key battery as soon as you begin to see low battery signs.
