Lockouts

One of the most devastating things that can happen to a driver is becoming locked out of their vehicle. There are, however, a few tricks that drivers can apply to gain access back into their vehicle. It is best to first call their local Mazda dealership or locksmith. This is a great option, as it will likely be less expensive and quicker than calling a tow-truck. The locksmith or dealer will require a key code from the database in order to cut you a new key fob, which is usually around $100. This is the reason it's essential to save the code in a secure place.

If you're stuck in the car, the other thing people can do is look for an auxiliary key that is located on the underside. There is typically an oblong, small button that can be press and held. This will open the doors of the vehicle, allowing the driver to open them by hand.

Another way to enter an unlocked vehicle is using the emergency override feature. This will allow the key fob to bypass the functions that are suspended by the theft-deterrent system. It will typically activate the hazard warning lights and beep signalling that the doors, fuel-filler lid or liftgate are locked.

Transponder Chips

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

The antenna ring emits a burst radio frequency energy when you insert your key made of metal and turn it on. The energy reaches the chip's transponder located in the key. The chip responds by sending an encoded message to the antenna ring. This tells the car that the key is in good condition.

Most Mazdas utilize a transponder chip with a rolling code which changes its code each time you turn the key. This means that your key will not function with your vehicle until you have a duplicate that has the exact same code in the ignition.

It's possible to create your own replacement keys. If you can find a key that works then insert it into your Mazda. Turn the ignition on. If the key starts your vehicle, you'll be able to copy the data from it onto the other key. If you need to, you can also use the eraser on your key fob to remove the code. This method is not guaranteed to be effective because some transponder chips recycled may not work correctly.

Programming

The loss of your car keys is costly and time-consuming. Fortunately, Mazda has made it easy to add and program the third key. You can do it in just a few steps and you won't have to pay the dealer for the service. You will not have to pay for towing or dealership charges if you have an additional car key.

The first step is to buy a new battery for the fob. You can purchase one at a big box store 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 tiny slots on the back of your fob. After taking the case off, replace the battery that was in it.

Now you can program your new key fob. Insert the first key that is working into the ignition and turn it ON. After about five seconds, then switch it off. Repeat the procedure with a second working key, and then with your new (or spare) key. Once you have done this then your Mazda should be able to be started with the newly programmed keys. If it doesn't, there could be a problem the key fob.
