How to change the battery in a Toyota Camry V55 and v50 key?

What kind of battery is in the key?

The Toyota Camry key usually uses a CR2032 3V battery. If you can't find an item with these specifications, you can install CR2016 3V. Both of these batteries have the same diameter, only the second one is slightly thinner. It should be understood that such a power source will last less, since its capacitance value is less than that of the recommended battery.

Step-by-step instruction

Now let's move on to step-by-step instructions for replacing the power supply. But taking into account the fact that the Toyota Camry v55 key fobs are structurally different from those used on the v50 model, replacing the battery in the key of these cars is carried out differently. Therefore, we will divide our story into 2 parts.

Comparison of key fobs of different models

In the photo above, the key for v55 is on the left and the key for v50 is on the right.

Toyota Camry v50

Toyota Camry v50 key fob If you turn the key fob with the logo towards you, positioning it properly, on the surface of the right side wall you can find a button with the inscription Push. You must click on it.

If left in this position, the emergency key can be easily removed from the housing.

Removing the emergency key

Upon closer inspection, you will notice that its tip has a certain shape. Thanks to this, the key fob can be disassembled without additional tools, which means it can be done while sitting in the car.

Key tip shape

We insert the key into the slot made specifically for this.

Mounting slot

Now it needs to be rotated axially to release the upper and lower parts.

Separation of components

As a result, we get two halves of one device.

The battery is closed with an insulating cover, which is secured with special plugs.

Insulation cover holders

They must be disconnected to access the battery. This can be done using a key. After removing the cover, the battery is exposed.

Location of the battery in the key fob

Sometimes the battery fits very tightly into the socket, so there is a special cutout into which a screwdriver or the key itself is inserted. Using them as a lever, the battery can be easily removed.

Removing the battery

Installation of a new element is carried out in the reverse order, so we do not consider it necessary to describe this operation in detail.

How to change the battery in a Toyota Land Cruiser key

Modern cars are equipped with chip keys. They are combined with protective mechanisms: immobilizer, ignition, etc. Without them, it is impossible to start the car. It is important to quickly change the battery in the Toyota Land Cruiser 200 key when it fails.

Design and appearance of the TLK 200 key fob

The Toyota Land Cruiser 200 key fob has a standard appearance for a chip: a black box with the manufacturer’s emblem on one side and the “Start”, “Stop” and “door lock” buttons on the other.

The TLK 200 key is an example of a technology called Smart Key. The key fob is equipped with a built-in radio tag, the job of which is to send encrypted signals to the main module installed in the car.

The range is 1-2 meters. If the key is removed from the car, the security mode is activated: the doors, trunk and hood are automatically locked.

If there is no tag when a person gets into the car, then he will not start the engine - the ignition and immobilizer are blocked.

Premium cars, which include the Kruzak 200, start when you press the Start button. The car reads the signal sent by the chip, recognizes it, opens the central lock and gives the owner access to the interior. After this, the person needs to press a button to start the engine. This mode is called Hands Free.

Recently, developers have been trying to complicate the mechanism of signal transmission between the key fob and the car, using cryptographic encryption. It works as follows: the immobilizer sends a message to the transponder (key), which encrypts it and transmits it back to the car. The car unit in parallel compiles a code for the set of letters and numbers sent to it and compares the result with the received signal from the key fob. If the data matches, then the car opens and is ready to go.

Due to the complexity of the mechanisms, it is necessary to monitor the battery charge level in the key fob.

If it runs out, then you need to replace the battery in the Toyota Land Cruiser 200 or 150 key as soon as possible.

When to change the battery

The battery life in the key fob depends on the type of installed energy sources. If the key is equipped with rechargeable batteries, they will last 3-4 years. They need to be charged periodically. If the key fob contains regular batteries, then their service life is much shorter.

The service life of the batteries is individual and depends on how often the owner uses the car, opens, closes, and starts it. It is recommended to use the key fob only in the immediate vicinity of the car. This way, less power is wasted, which extends the life of the battery.

The Toyota Land Cruiser “Keyless Go System” notifies the driver that the battery in the key is low and that it needs to be replaced.

A dead battery in a key fob is often a problem that takes drivers by surprise. They think there is still time for a replacement, but in reality there is none left. Because the key does not work, the owner cannot either lock the car or get inside and start it. In this case, you need to replace the battery in the key on a Toyota Prado 150 or TLK 200.

If the battery is discharged and there is no way to change it, then you can try several ways to temporarily bring the battery back to life:

• lightly tap it on something hard;
• press the edges of the battery with pliers, a chair leg or other object, thus activating the energy reserves that remain in it without harming the case;
• if there is nothing suitable at hand, then you can use your teeth to press the ends of the body;
• resuscitation of the battery with a short-term charge from the battery;
• warm up the battery a little by friction (on trousers, seat, etc.).

If the key fob is powered by a battery, then any attempt to restore its functionality independently using “folk” methods will lead to its breakdown.

Which battery to choose to put in the keychain

When it's time to change the battery in the Toyota Prado 150 or 200 key fob, it is important to choose the right battery type and power. To make the key fob work like a clock, it is best to buy a new battery of the same type as was installed at the factory.

Toyota Land Cruiser Prado and Kruzak 200 of any year have built-in 3-volt CR1632 batteries. You can buy them at any hardware or automotive store for pennies.

Guide to replacing the battery in a Toyota car key

Due to the fact that there is not much information about replacing the battery, drivers are often intimidated by this procedure. In fact, changing the battery in the key of a Toyota Land Cruiser Prado 150 or 200 is easy and quick. This will require a little dexterity and knowledge of how to open the key body.

Important rules for using the key fob

Replacing the battery in the latest generation Toyota Rav 4 key does not require special tools or skills. However, precautions should be observed during daily use, which are recommended by the manufacturer.

1. Don't press the buttons too hard.
2. Observe the temperature conditions for storing the key.

In order for the key to always work properly, it is necessary to timely replace the battery in the Toyota Corolla key.

Keys in foreign cars are not just products for unlocking doors or igniting the engine, but a modern high-tech device. It usually takes the form of a small key fob with several buttons. Inside there is an electronic circuit that performs several important functions, namely:

• Controls the vehicle alarm.
• Allows the vehicle system to identify the owner.
• Protects the vehicle from theft.

Most foreign cars are equipped with an immobilizer. Thanks to the built-in chip with a code, the car’s on-board computer identifies the owner. Only after the system has identified you can you turn the key to start the car. Otherwise, the motor will simply block. It is worth noting that such an advanced system can create problems for the owner. As a rule, this is due to the fact that the battery in the key has exhausted its resource.

When to change

One fine morning you press the key button, but the car does not react at all. No worries. Most likely the battery just died. In this case, you will not be able to perform any manipulations. It is recommended to replace it immediately without wasting time. In some cases, when using a key, the system may display a message that it is not recognized. This may also indicate that the charge is coming to an end.

Battery life varies from person to person as it depends on frequency of use. Car owners recommend using the key only in the immediate vicinity of the car, where the signal is strongest. In this case, less battery power is wasted, which extends the service life.

Replacement process

At first glance, it seems that the structure is non-demountable. Many drivers ask how to change the battery in a Toyota Corolla key. Every car owner can do this independently in just a few minutes.

First you need to prepare a regular flat-head screwdriver. You should also buy a new battery. The design uses a flat “tablet” CR 2016 3V. Its estimated cost is around 100-200 rubles.

There is also a CR2020 model, but it is thicker.

If you are interested in the question of how to replace the battery in a Toyota Corolla key, then follow these instructions:

The installer will be shown how many keys are “registered” and how many more can be added. In the right corner of the new plate there is a column “Pre-start CHK”. Click on the animated “Start” icon, which starts the stopwatch for 30 seconds. At this time, you should bring the programmable key fob with the Toyota icon to the sound signal. When finished, click “Next” and exit the program. They close the laptop, disconnect it from the car’s on-board computer and check the results of their work.

A duplicate key, if available, can be programmed as follows:

1. Press and release the brake and gas pedals at the same time.
2. Insert the working key into the lock, but do not turn it.
3. After this, within 15 seconds, press and release the gas pedal five times.
4. Then, within 20 seconds, press and release the brake pedal 6 times.
5. Now, in 10 seconds, the programmable key is inserted into the Toyota Camry ignition switch.
6. In another 10 seconds, press and release the gas pedal once.
7. After about 80 seconds, the security lamp will go out, the key fob is removed from the lock, and the brake pedal is pressed and released once.

The work is done, the key can be used for its intended purpose.

How to get a new key and how much it will cost

In order to obtain a Camry unlocking device, the owner should contact a Toyota dealer or a service center offering a car key restoration service, where they will help make and program the device correctly.

The car owner must decide, based on the technical equipment of his car, which type of key will be suitable: smart, transponder or without a chip. Many of them are similar, but have different characteristics in terms of the list of capabilities and structure.

Information that should be provided to the technician when recreating the car key:

1. Year, make and model of the vehicle, for example: 2012 Toyota Camry.
2. VIN number of 17 characters to determine the type of device being requested.
3. Documents on car ownership.

A screwdriver with a hot tip is best. An electrical probe will not work - many of them do not have a hardened tip, which can bend when opening the case. In addition, their size is too small and they will damage the plastic.

Also, if you are using a smart key with a retractable ignition switch, you can remove it and use it instead of a screwdriver. Or use another flat shape, for example, from an apartment.

The battery is changed as follows:. It is better to choose one that is more expensive and from well-known manufacturers - if the chip gets into water, it will do nothing, but the door opener circuit board can be damaged by alkali spilled from a cheap battery with a leaky case.

How to change the battery in a Toyota Camry key

• What to do
• Instructions
• Conclusion

A key fob for a Toyota Camry is a very useful device, because it greatly simplifies the process of driving a vehicle.

The main task is to understand the best way to replace the key battery. Such a replacement actually requires a minimum of time and effort.

Despite this, many owners of the Toyota Camry V50, as well as the Camry V40, cannot understand what the process of replacing the battery is.

What to do

The most unpleasant moment is the complete discharge of the battery. If the battery is completely discharged, remote control of the Toyota Camry is no longer possible. Using the key fob you will not be able to open the doors or the tailgate in a timely manner.

In addition, there will be serious problems with starting the car, because the anti-theft system will still work. It is not surprising that replacing the batteries in the Toyota Camry key becomes an important and urgent task.

To replace it, a small flat screwdriver is traditionally used, with which you can complete the task in the shortest possible time.

You need to be prepared for the fact that replacing the battery in the Toyota Camry key will not lead to a quick solution to the problem.

If the vehicle key fob still does not work successfully, it will need to be re-programmed to suit the vehicle's requirements.

This is due to the fact that when replacing the battery, the memory of electronic devices may be completely cleared, after which they are temporarily unable to successfully perform their tasks. For further successful use of the key fob, it is advisable to contact the car service employees, because they will be the ones who will be able to re-program it in order to resume the previous functions.

It should be noted that many Toyota Camry owners try to replace all batteries when cold weather sets in, so a new battery is also selected for the key fob. At the same time, contacting the service center employees to install a new battery is an impractical step, because the payment for their services promises to be excessively high. It is best to carry out the planned event yourself, because it does not involve particularly complex processes.

Instructions

So, how do you replace the battery in your key?

To carry out the procedure, you will need a car ignition key, a new battery, a screwdriver, and a paper clip.

1. At the very beginning, you should open the key using a suitable screwdriver. It is best to choose the right size, as otherwise the plastic key may become deformed.
2. The key fob is best opened carefully, moving clockwise. With the right approach, the case will definitely open.
3. Another building will be visible inside. This is where the battery is hidden. After the housing is opened, the main replacement stage can be carried out. In this case, the fastening of the two parts of the second body is held on by two latches, so they need to be opened using a paper clip or fingernails.
4. Now you need to pry the battery up and pull it out. A spring mechanism is used to secure it. Now the battery can be changed.
5. The assembly process is carried out in reverse order.

Conclusion

Knowing how to change the battery in a Toyota Camry key, you need to remember: the replaced element can work successfully for up to three years, but it is best to change it once a year.
