Mazda 3 Key Fob Replacement
There are occasions when a Mazda 3 owner might need to change the battery in their key fob. This is a simple task you can perform yourself.
To change the battery, find the small button on the back of the key fob. Press the button, then remove the cover.
Lost Keys
The loss of your car keys was an inconvenience that was minor. It was comparatively inexpensive to replace them in any hardware store, dealer, or locksmith. The car's high-tech key fob can do much more than just lock and start the vehicle. However, this added convenience comes with the cost of replacements.
The key fob is equipped with a security chip that transmits an individual code to the computer in the car that allows it to unlock and start it. The key fob is capable of controlling some other functions, such as closing the windows if you're in a hot parking area and summoning your car to you for easier reversing into a tight spot (a feature that is available on certain Genesis GV60 and Hyundai Sonata sedans).
Luckily, Mazda's remote fobs aren't nearly as expensive as those from other automakers. You can even replace the battery of your key fob by yourself with a little bit of knowledge. You'll require a flathead screwdriver as well as the new CR2025 to complete this. Make sure you use the directional buttons along with the red button to lock and unlock the doors prior to changing the battery.
If you're looking to cut costs, find an Mazda 3 keyfob online that is OEM. It doesn't require programming by an authorized locksmith or dealer. You'll find many options on eBay but they might not have the same design or color as your current key fob.
Lockouts
A driver being locked out of their car is one of the most traumatic things to happen. There are some tricks that drivers can employ to gain entry into their car. First, they can try calling the local locksmith or Mazda dealership. This is a great idea since it's likely to be cheaper than calling a tow truck and will be faster as well. The dealer or locksmith will require a key code from the database to cut you a new key fob which usually costs about $100. It is essential to keep the code secure.
Another thing people can do when stuck outside of their vehicle is to examine the underside of the key fob in search of an auxiliary button. There is typically a small, round button that can be pressed and held. This will open the doors of the vehicle, allowing the owner to open them manually.
Another method to gain entry into a locked vehicle is by using the emergency override feature. mazda key programming allows you to use the key fob override any functions that have been suspended by the theft deterrent system. This will activate the hazards lights and sound to confirm that the doors, fuel filler lid or liftgate are shut.
Transponder Chips
You'll need to replace it if your key fob is equipped with an embedded transponder in the head of the L-shaped key. These chips are equipped with an identification code that allows you to start your vehicle.
The antenna ring emits radio frequency energy when you insert your key made of metal and switch it on. This energy reaches the chip's transponder located in the key. The chip responds by sending an encryption code to the ring. This tells the car that the key is valid.
Most Mazdas use a rolling code transponder chip that alters its code each time you turn the key. This means that the key will not work on your vehicle until you have a second copy with the exact code in the ignition.
It's not difficult to create your own replacement key. If you're able to locate an original key, insert it in your Mazda and set the ignition to ON. If the key is able to start your car, you can then copy the data from it onto the other key. You could also try the eraser procedure on your key fob to remove the current code, if required. This method isn't 100% guaranteed to work since some transponder chips can fail to function properly.
Programming
The loss of your car keys is expensive and time-consuming. Fortunately, Mazda has made it easy to program and add a third key. It's done in a couple of steps, and you won't need to pay an agent for this service. If you have a spare car keys, this is the best method to avoid having to pay for towing charges and dealer charges.
You'll need to buy an extra battery for your key fob. You can purchase one at a big box retailer or hardware store for around $10. To open the fob, you'll need an screwdriver with a flat head. The screwdriver's head should fit into small slots on the back of the fob. Once you've removed it you'll have to replace the old battery with the new one.
Now you can program your new key fob. To do this, simply insert the first working key into the ignition, and turn it to ON. It should be on for about five seconds and then turn off the ignition. Repeat the process using another key that is working before switching to the new (or additional) key. Once you've done this the new key should be capable of starting your Mazda. If it doesn't, there may be a problem with the key fob.
