Lockouts

A driver being locked out of their car is among the most unpleasant things that can occur. Luckily, there are few tricks that drivers can apply to gain access back into their vehicle. First, they can try calling the local locksmith or Mazda dealership. This is a viable option, as it will likely be less expensive and faster than calling a truck. The locksmith or dealer will require a key code from the database to create the new key fob which typically costs around $100. This is the reason it's essential to keep the code in a safe place.

If you're stuck in the vehicle, another thing you can do is search for an additional button on the bottom. There is usually an oblong, small button that can be press and held. This will open the doors of the vehicle, allowing the owner to open them by hand.

This will allow you to use your key fob to disable any functions that were suspended by the theft deterrent system. This will trigger the warning lights and sound to prove that the doors, the lid for the fuel filler, or liftgate is closed.

Transponder Chips

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

When you insert your key and then turn it to ON, the antenna ring sends out an impulsive radio frequency energy that will reach the transponder chip within the key's metal. The chip responds with an identifier that is transmitted to the antenna ring, telling the car that it's an authentic key.

The majority of Mazdas have transponder chips that have an evolving code that changes every time you turn it. This means that your key will not work on your vehicle until you have a duplicate that has the exact same code in the ignition.

Fortunately, it's not impossible to create your own replacement keys. If you can locate an original key that works and fits into your Mazda. Then, turn the ignition on. If the key is able to start your vehicle, you can copy the information to the other working key. You can also try using the eraser method on your key fob in order to erase the current code, in the event that it is needed. It's important to note that this method is not 100% guaranteed to work, since some transponder chips recycled from the past might not work correctly.

Programming

You'll also require a flathead screwdriver to open the fob. The screwdriver's head must fit into a small slot or a space on the back of the fob. Once you've removed the case and battery, you'll need to replace the old battery with the new one.

It's time to add the new key fob for your vehicle. Insert the first key that operates into the ignition and turn it on. It should take about five seconds and then turn the ignition off.

If it does not it could be due to a issue with the key fob or vehicle.
