There are occasions when a Mazda 3 owner might need to change the battery on their key fob. It is easy to complete this task yourself.

Find the small button located at the back of your key fob. Press it, then take off the cover.

Lost Keys

Losing your car keys was a minor inconvenience. You could replace keys at any hardware store, locksmith store, or dealer, and it was fairly inexpensive to do it. Today, your car's advanced key fob does much more than just lock and start your vehicle with ease, and that added convenience comes at a price: more expensive replacements.

The key fob has a security chip that transmits an individual code to the computer in the car to allow it to be unlocked and start it. The key fob is also able to be used to control other features, like rolling down your windows in hot parking areas and requesting the car to come to you so you can reverse into a tight space (a feature that is available on certain Genesis GV60 sedans and Hyundai Sonata sedans).

Mazda's remote controls don't cost nearly as costly as other car manufacturers'. You can even replace the battery of your key fob by yourself with a little bit of know-how. You'll need a flathead screwdriver and a brand new CR2025 for this. Use the red and directional buttons to lock and unlock your doors prior to changing the batteries.

If you want to save money on the cost of a Mazda 3 key fob replacement, look for one online that is OEM and does not require programming by a locksmith or dealer. You'll find many options on eBay but they might not have the exact design or color as your current key fob.

Lockouts

One of the worst things that can happen to a driver is becoming locked out of their vehicle. There are, however, a few strategies that drivers can utilize to get back in their car. First, they should try calling their local locksmith or mazda key fob dealership. This is a great option as it is likely to be less expensive than calling a tow truck and will be faster too. A locksmith or dealer needs to purchase a key code from the database to make you a new fob. It will cost around $100. This is why it's important to save this key code in a safe location.

If you're stuck in the car, the other thing people can do is look for an additional key on the underside. The button is usually smaller and round, but can be activated. This will unlock the doors of the vehicle and allow the owner to open them manually.

Another way to get into a locked vehicle is by using the emergency override feature. This will allow the key fob to take over the functions that are suspended by the theft-deterrent system. This will usually activate the warning lights for hazard and sound sound for confirmation that the doors, lids for fuel-filler or liftgate are locked.

Transponder Chips

You'll need to replace it if the key fob is equipped with a transponder that is built into the metal head of the L-shaped key. The chips are unique in identification number that is used by your vehicle to start the engine.

The antenna ring emits a blast of radio frequency energy when you insert your key in the metal and turn it on. This energy reaches the chip's transponder located in the key. The chip responds with a code that's sent to the antenna ring, telling the car that it's a valid key.

Most Mazdas have a transponder chip with a rolling code that changes each time you turn it. This means that your key will not work on your vehicle until you have a second copy with the exact same code in the ignition.

It's not difficult to make your own replacement keys. If you can locate an original key, insert it in your Mazda and turn the ignition to ON. You can copy the information from the key to the other key, if it starts your Mazda. You can also use the eraser process on your key fob to erase the current code, in the event that it is needed. This method isn't 100% guaranteed to work because some transponder chips that are recycled might not work properly.

Programming

Losing your car key can be an expensive and time-consuming process. Fortunately, Mazda has made it easy to add a third key. This can be accomplished in just a few steps and you won't need to pay an agent for this service. You will not have to pay for towing charges or dealership charges if you have an extra car key.

First, you'll need to purchase an extra battery for your key fob. You can buy one from the hardware store or at a big box retailers for around $10. To open the fob, you'll require a flathead screwscrew. The screwdriver's head should fit into a small space or a space on the back of the fob. After removing the case replace the battery that was in it.

Now it's time to set up the new key fob in your vehicle. Insert the initial key that works into the ignition and turn it on. It should be on for about five seconds then switch off the ignition. Repeat the process using a second working key, and then with your new (or spare) key. After this is done the new key should be in a position to start your Mazda. If it doesn't, there could be a problem with the key fob.
