Find the small button on the back of your key fob. Press the button and then remove the cover.

Lost Keys

Before the 1990s losing your car keys was a minor inconvenience. It was fairly inexpensive to replace them in any hardware store, dealer, or locksmith. Your car's high tech key fob can do much more than simply secure the vehicle and open it. However, that added convenience comes with cost - higher prices for replacements.

The key fob features a security chip built into it that sends a specific code to the car's computer in order to allow you to unlock and begin the engine. The key fob is also able to be used to control other features, like opening your windows in hot parking spaces and summoning the car to you in order to reverse into a tight space (a feature available on some Genesis GV60 sedans and Hyundai Sonata sedans).

Fortunately, Mazda's remote fobs aren't as costly as those from other automakers. If you have the right knowledge you can replace the key fob's battery yourself. You'll require a flathead screwdriver as well as a brand new CR2025 to do this. Use the red and the directional buttons to lock and unlock your doors before changing the batteries.

If you're looking to cut costs and save money, look for a Mazda 3 keyfob online that is OEM. It doesn't need programming by a locksmith or dealer. eBay has a variety of options but they might not be the same color as your existing key fob.

Lockouts

A driver who is locked out of their car is one of the worst things that can happen. Luckily, there are few strategies that drivers can utilize to get back into their car. The first step is calling the local locksmith or Mazda dealership. This is a good option since it's likely to be less expensive than calling a tow truck and will be faster too. The dealer or locksmith will require a key code from the database in order to create an additional key fob, which is usually about $100. This is why it's vital to keep the key code in a safe location.

If you are stuck in the car, the second thing people can do is look for an additional button on the bottom. There is usually small, round button that can be placed and held. This will open the doors of the vehicle and allow the driver to open them manually.

The emergency override feature is a second way to gain access to an automobile that is locked. This allows you to use the key fob to bypass any functions that are suspended by the theft deterrent system. This will trigger the warning lights and sound to confirm that the doors, lids for the fuel filler or liftgate are closed.

Transponder Chips

You'll have to replace it if the key fob has a transponder that is built into the metal head of the L-shaped key. These chips contain an identification code that allows you to start your car.

When you insert your key and turn it to the ON position, the antenna ring emits a burst of radio frequency energy that gets to the transponder chip that's in the key's metal. The chip then responds with the code that's transmitted to the antenna ring telling the car that it's a valid key.

Most Mazdas are equipped with a transponder chip with a rolling code which changes its code each time you turn the key. This means that the key you're using isn't going to work on your vehicle until you have a duplicate that has the exact same code in the ignition cylinder.

It's not hard to make your own replacement key. If you're able to find an original key, insert it inside your mazda replacement key and set the ignition to ON. If the key is able to start your car, you'll then be able to copy the information to the other key. If necessary, you can also use the eraser on your key fob in order to remove the code. This method isn't guarantee that it will work because some transponder chips can fail to function properly.

Programming

Losing your car keys is an expensive and lengthy process. Mazda has made adding and programming a third car key easy. It's done in a few simple steps and you won't have to pay an agent for this service. If you have a spare car keys, this is the most efficient way to avoid paying for towing charges and dealer costs.

You'll need to buy new batteries for the key fob. You can buy one at a big box store or hardware store for around $10. To open the fob, you'll need a flathead screwscrew. The screwdriver's head must fit in a small slot or a space on the back of the fob. After removing the case, replace the battery that was in it.

Now you can program your new key fob. To do this, put the first working key into the ignition, and turn it to ON. After about five seconds, and then switch off the ignition. Repeat the process with a different working key, and then your new (or spare) key. After this is done the new key should be capable of starting your Mazda. If it doesn't, there may be a problem with the key fob.
