“Can I replace the key fob battery myself?” This is a question many car owners ask, and the answer is generally yes, you can. Replacing the key fob battery involves prying apart the key fob and replacing the coin battery inside with a new one. If you’re not mechanically inclined, you can always seek help. It’s important to note that we are primarily discussing car key fobs here because apartment key fobs typically don’t use batteries. If you’re curious about apartment key fob batteries, check out our previous blog post, “Do Apartment Fobs Have Batteries? Learn Where The Power Lies”, where you can learn why apartment key fobs don’t have batteries and how they function.
So, if you’re considering replacing your car fob battery, yes, you can do it yourself. However, if you’re unsure or prefer professional assistance, we recommend visiting our trusted partner Pop-A-Lock or coming to our headquarters at FobToronto, where we offer battery replacement services. *Please note that we do not specialize in car key fob copying services, and we are not responsible if the remote is damaged while trying to open it and change the battery, as it’s not our primary area of expertise. Additionally, keep in mind that because we don’t typically handle car key fobs, we might not always have the specific battery you need. However, most car fobs use a limited range of 2-3 battery types, so we likely have what you need.
What Happens if Your Car Key Battery Dies?
The battery in your key fob is essential for its operation. It powers the remote functions and, in push-to-start (PTS) vehicles, is crucial for starting the car. A dead battery can prevent your car from starting, which is why it’s important to replace it when needed.
Most smart keys come equipped with an emergency blade (E-blade), which is a mechanical key placed inside the fob. The E-blade can be used to open the driver’s side door in an emergency, such as when the battery is dead.
How Do I Know If My Car Key Battery Is Dying?
One of the first signs that your key fob battery is dying is when the transmitter starts losing its range. If you notice that you have to be closer to your car than usual for the key fob to work, this could be a sign that the battery is weakening. Other indicators that your key fob battery needs replacing include:
- The key fob isn’t sending out a signal.
- You have to press the button multiple times before your car responds.
- The key remote is inconsistent or unreliable.
