8 Easy Steps to Change Battery In Subaru Key Fob
Click inconsistencies and reduced signal range indicate an underlying battery issue – probably a cell running out of power. For instance, you may note that unlocking the car was delayed for up to 3 seconds, or your vehicle’s headlights didn’t blink upon unlocking.
We’ve curated some steps for an easy battery replacement. But you need a few tools before you begin. Make sure you keep a tape, a screwdriver, and a butter knife handy.
Once you have the items, proceed with the replacement.
1 – Detach the Mechanical Key
To begin with, you’d need to detach the mechanical key.
You’ll find a button mounted on the fob’s back if you look closely.
Press this button to remove the mechanical key. If you cannot accessibly reach the tiny groove of the button, you can press it down with a screwdriver.
As the button presses down, use the other hand to detach the mechanical key.
2 – Use a Screwdriver to Open the Housing
You’d need to open the housing to uncover the control module. While you can directly use the screwdriver for the purpose, it is better to tape it to prevent damaging the control module.
Now insert the screwdriver tip to separate the housing. As soon as you split it into two, you’ll find that one houses the control module while another is used as a covering.
3 – Remove the Control Module
Once you separate the housing, you’ll discover the control module, including the battery. Gently lift out the module to remove and replace the battery.
As a rule of thumb, mark the housing that features the control module. This step will make it easier for you to place back the control module.
4 – Take out the Battery
Generally, metal contacts keep the battery in place. You can use a butter knife to displace the battery from its position. However, do it cautiously to prevent damaging the control module.
5 – Place the New Battery
Although CR 2025 3V and CR2032 3V are two popularly used batteries for fob battery replacements, you can always check your vehicle’s manual to find an ideal replacement.
Just make sure that the battery fits right and touches the metal contacts properly for effective results.
6 – Add the Control Module
Once you insert the new battery, place the control module into the marked housing. If you’ll return the control module to the right housing, closing it will be straightforward. Otherwise, you’ll struggle at this step – which explains why we suggested marking the relevant housing.
7 – Cover the Housing
Cover the housing featuring a control module using a second housing. Pressing one against another is all it takes to close the housing.
8 – Insert the Mechanical Key and Test
Now return the mechanical key to its original place. Fortunately, it’ll be a lot easier than the removing process.
But your battery replacement doesn’t end here. Testing the key fob is a must to ensure appropriate battery replacement. Use it to lock and unlock the car. Besides, try other features to ensure it’s working correctly.
If the key fob fails to function, your vehicle may have an underlying issue. While it’s a bitter pill to swallow, cars – being gadgets – are prone to technical problems.
You can always contact a professional mechanic to identify and fix the underlying vehicle problems, and if your car is insured, it’s even better; the company takes responsibility for repairs.
Subaru Replacement Tips
Let’s face it; anyone is rarely on budget, and key fobs are pretty expensive. Besides, they require re-programming after buying. Therefore, it is always good to know a few tips for Subaru key fob battery replacement.
Not only will it save you money, but it’ll keep you from additional stress.
Check Your Car’s Insurance or Warranty
Before you purchase a new key fob, knowing if your damaged or lost key is covered under any car-related policies is essential. This cost-saving measure will cut down on or eliminate out-of-pocket expenses.
If your insurance or warranty covers the lost keys, you’ll keep yourself from replacement hassles.
Reach Out to the Dealer
If it’s been 5 years since you bought your car, we recommend reaching out to the dealer for a key fob battery replacement. Why? Because an aftermarket fob might not function with your vehicle.
Yes, you can program a few fobs, but they follow up with risks.
Generally, removing the mechanical key and programming the fob will take around an hour.
If you can afford to pay for an aftermarket fob, a dealer can adjust it for you. But, it is pretty risky and not advised by pros.
Replace the Shell
If your key fob is operating adequately, but there’s an issue with the shell, you can always replace it – instead of buying a new fob.
A thin blade screwdriver is all you need to mount the new shell. It’ll only take a minute or a 2 to swap the control module from the old shell to the new.
You can always consider the above-discussed steps for shell replacement, but you won’t need to remove the battery this time.
Place an Online Order
Is your car 10 years old? If yes, go for an aftermarket fob. You can order them online because they aren’t always available in the stores.
An automotive locksmith or a professional mechanic can manage the programming for you.
Contact the Locksmith
If you’re not into DIYing, get in touch with an experienced locksmith. Not only will it save the costs of buying a key fob, but it’ll also minimize the time you’ll cluelessly spend trying to fix the fob.
Because most locksmiths are mobile, driving to your office or home isn’t a problem for them. Besides, it’ll eliminate the trouble of taking your car to the locksmith’s shop.
