Why Your Mitsubishi Spare Key Isn't Working
Low battery is the most likely cause of your Mitsubishi key fob not responding to lock or unlock commands. This will require a replacement battery, which can be purchased from the dealer or from an automotive locksmith.

The procedure for replacing the battery of a car key fob is relatively simple and can be done at home using a screwdriver.
Keyless Entry
Mitsubishi's keyless entry system is a useful feature that allows you to unlock your vehicle without having to press a button on the fob or insert the key into the lock. The system is based on an integrated receiver inside the car that senses the signal from the key fob. The car will recognize the signal and open the doors as you come closer. This makes it much easier to get into the car if your hands are full or you're in an urgent situation.
The standard feature on all Mitsubishi models is keyless entry. Certain models allow you to open and close the power liftgate from a distance and start your engine by pressing a button. The system can also be used to activate the headlights if you are driving in the dark.
If you've lost your Mitsubishi key fob, don't panic. There is a method for re-syncing the key fob to your vehicle. The key fob must be within a specific distance of the car's receiver to allow the system to function. You won't be able to use it if the key fob isn't near.
First, make sure that your key fob is powered enough to operate. Then, hold and press the lock and unlock buttons until your vehicle's light flash three times. Then, push the unlock button until the light flashes two times. The key fob will be resynchronized with the vehicle. It will be able to lock and unlock your car and also perform other functions that you have programmed.
Your key fob could be having a battery issue if it is not responding to commands. This is more likely when you've been using your keyfob for a long duration of time. It's not difficult to fix. With a little patience and a few tools, you can easily replace the battery on your key fob. It's not as difficult as you think, and you can save money by doing it yourself rather than paying someone else to complete the task.
Transponder Keys
When it comes to car key replacement, there's a variety of choices. You can either call a locksmith or go to the dealership. Depending on your situation, one option may be superior to the other.
The most popular kind of car keys are transponder keys. These are advanced versions of car keys that have a microchip inside them, which makes it difficult for thieves to take your car. The car will only start if the key is recognized by the car. This is crucial as it stops thieves from using fake keys or hotwiring to start your car.
The chip is usually located inside the head of plastic of your car key. When you insert the transponder in your ignition, it will send an indication (a portmanteau combining "transmitter", "responder" and "transponder") to your car's anti-theft device. The immobilizer then compares the signal with the one stored in the transponder to verify that it's the correct key. The car will then allow it to start.
These are advanced types of keys for cars, and they're a great way to protect your Mitsubishi Galant from theft. These keys are compatible with remote key fobs that combine the key and remote into one unit.
A locksmith for cars will be able to cut and program the keys for you. The locksmith must be aware of the model, make and year of your vehicle. They can help you choose the correct key for your vehicle whether it's a steel key or transponder key.
There are also keys that don't have chips, but function with Mitsubishi's system. These keys are known as proximity keys and cost less to manufacture than other kinds of keys. However, they're not as reliable as a regular key or a transponder key. Avoid keeping a proximity-key near objects that could damage it, such as electronic devices or metal objects.
Key Batteries
Modern Mitsubishi vehicles are equipped with key fobs that permit drivers to lock and unlock their vehicle from afar. These safe and convenient devices are made of sturdy materials that are designed to last an extended period of time. Like all electronic devices requires regular maintenance and replacement of parts. When a Mitsubishi key fob battery is damaged it could cause the device to stop working completely. The process of replacing the battery is done in just a few minutes.
To change the Mitsubishi key fob battery, you'll require just a few basic items. You'll first need a small screwdriver. Find an indentation on the top of your Mitsubishi key fob, and make use of the screwdriver to open the case. Replace the old battery and remove the physical key. Close the case for the fob and then insert the key again to complete the procedure.
Remotes
Mitsubishi vehicles are full of convenience features to ensure that your journey is as smooth as possible. Key fob is one of these features that allows you to lock and unlock your car from a distance. If, however, your Mitsubishi key fob stops working it can be a frustrating and challenging to fix. Luckily, there are ways to solve the problem that will get your vehicle back in operation quickly.
The first step is to be aware of the various types of key fobs that are available for your Mitsubishi Galant. Models from 1993-2005 use a regular metal key, while models from 1996-2012 have a remote fob that combines the functions of a remote and key in a single device. If you own key fobs from the second category, you'll have to program it in order to take advantage of all its features.
Most modern Mitsubishi models are equipped with the ability to start your engine remotely from a distance using the key fob, or the My Mitsubishi Connect app. G28 can choose to remote start your car on the home screen of the app which can be accessed by clicking on an icon that appears like an engine. When you tap the icon, you'll be prompted to enter your 4-digit security PIN to begin the engine.
You can also press the button on your key fob to turn off the engine should you change your mind. The icon on your key fob will change to a "STOP", which will blink when you are within range of the vehicle.
You may have to replace the battery if your Mitsubishi key fob does not respond. It's important to use the correct type of batteries for your key fob, since different types require a specific voltage in order to work properly. Avoid storing your keyfob near any objects that could damage the battery.
