How To Change Battery In 2011 Toyota Rav4 Key Fob

I’ll walk you through the process of disassembling your Toyota RAV4 key fob so you can replace the internal battery at home in this brief lesson. If you look closely at this key fob, you might have something that resembles it exactly, however some of them have a shiny finish inside. I think some of them have three buttons. I have four. The model with three buttons might be yours.

Do not be concerned; the button and device are same. Sorry, same batteries, same opening procedure. So on and do as instructed. We’ll install a new battery for you. One of these CR 2032 batteries is required.

Check out the link in the description below if you don’t know where to acquire one or if you’d want to order one online. You may go there to purchase one on Amazon for just a few dollars. And that will be the precise battery you require for this gadget. Simply looking at the bottom is the first step. You can see that this tiny switch will be held down to release the internal battery.

Leave that alone. A keyhole is present here. The key immediately emerged from there. And directly across from it, parallel to it, there is a little slit in the plastic that we will use a standard flathead screwdriver to open this item. So, keyhole once more.

The region I’m referring to is this one. Therefore, place your flathead screwdriver there. The back side, not the button side, should be facing up for the greatest results. And by just entering and turning our screwdriver in the appropriate location, we can now remove this, set that aside, and remove this. If this tiny rubber component disappears, these buttons may also come out.

Therefore, carefully place it down while keeping it orientated in this direction. And this is the only thing we’ll be working on: this tiny component. You can see a small hole up top, directly above the battery. That’s the approach we want to take. You can either use a flathead screwdriver or try poking it out from the corner.

It is preferable to use a smaller screwdriver or just a tool that can fit within that hole. If you have a tool that is the correct size, it just pulls out really easy, so I’m going to use this tiny precision screwdriver here. This is definitely something you can use in a pinch, and I have. You simply sort of get under, it requires a little more energy, and you risk slightly scratching the surface. So I definitely wouldn’t advise that.

If you don’t have anything similar, you can pry this out using a paper clip by folding it out, inserting it, then releasing it. Possibly a toothpick, a Bobby pin, or something similar as well.

After changing the battery, does a key fob require reprogramming?

A remote key fob needs to be associated with your vehicle particularly in order to be secure.

This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.

Standard programming sequence

Your key fob can typically be reconfigured by following this typical procedure:

Instead of starting and then returning to the locked position, turn the key into the run position. Repeat this multiple times.

You’ll typically hear a chime or other sound when you’ve cycled the key enough times. At that point, you can push the lock or unlock button on your key fob to hear another chime.

How can I tell if the battery in my Toyota key fob is dying?

A key fob is one of several electrical components in contemporary vehicles. When you press the button to open the door, a transmitter electronic chip inside of it broadcasts the signal. A small battery powers the key fob. In a smart key fob, the battery may last for 2-3 years, whereas it may last for 4-6 years in a standard key fob.

The smart key fob also contains a receiver, so when it is inside or close to the car, it must connect with the car more frequently, which accounts for the disparity. A key fob battery is often not rechargeable and needs to be changed when it runs out of power.

What symptoms indicate a weak fob battery? The transmitter’s range decreases as the fob battery gets weaker. This implies that for the key fob to operate, you must be close to the vehicle. If the smart key fob battery is low, a vehicle that has a push-button start may not always detect a smart key fob that is in your pocket or handbag. Key fob battery low may also appear as a warning on the driver’s display in some vehicles.

If the fob battery is low, will the car start? The security (immobilizer) chip inside the fob operates without a battery in the majority of cars, but only when it is quite close to the vehicle. Therefore, even if the fob’s battery is poor, the car should still start. To start the engine, you might need to place the smart fob into a certain slot or hold it nearer to the “Start” button. For instructions, consult your owner’s handbook. It’s also possible to store a traditional mechanical key within the fob. If the main battery of a car is exhausted or the fob battery runs out, this key can open the driver’s door.

How can the battery in the fob be tested? Many key fobs have a tiny LED light that turns on when one of the buttons on the fob is pressed. If the LED light is completely dark, either the fob’s battery is dead or the fob is experiencing some other issue. You can use a voltmeter to check the voltage of the fob battery if you already have it out. The battery has a mark indicating the voltage.

This battery is defective since it displays 2.858 Volts. A reliable 3-Volt battery should register somewhat higher than 3 Volts.

A 3-Volt battery is weak if it displays less than 3 Volts. As an illustration, the 3-Volt battery in the picture displays just 2.8 Volts; it is defective and needs to be replaced.

What kind of battery is needed for a key fob? The batteries used by various automobiles vary. Three-volt batteries come in two main varieties: CR2025 and CR2032. The owner’s manual will list the precise type. These kinds of batteries are available at any dealership or in any electronics store.

The battery for the fob can be changed easily. To find the instructions and safety measures, consult the owner’s manual. There are a ton of how-to videos on YouTube as well. A tiny flat or Phillips screwdriver can be required.

For instance, we used a little flat screwdriver to pry open the key fob in the top photo at the locations specified in the owner’s manual. Take care; the plastic tabs holding the fob’s components together are fragile and are likely to break. There may be small screws or other easily lost items in some automobiles.

Keep an eye out for the battery’s installation when replacing it. The “+” symbol is written on the one side of the battery. The new battery must be installed exactly the same way in order for it to function.

Visit your dealer; they should be able to change the key fob battery for you if you are not mechanically inclined. Most of the time, it only takes a few minutes. The rates we received from different sellers were all within $10. If only the fob battery needs to be changed, a key fob doesn’t require any programming.
