Lockouts
One of the most devastating things that can happen to a driver is getting locked out of their vehicle. Luckily, there are few tricks that drivers can use to get back in their car. You should first contact their local Mazda dealership or locksmith. This is a good option for a variety of reasons, and it's likely to be less expensive and quicker than calling a tow truck. A locksmith or dealer needs to purchase a key code from the database in order to make a new fob. This will cost approximately $100. It's important to ensure the security of this code.
Another thing that drivers can do when they are stuck outside of their vehicle is to examine the underside of the key fob for an additional button. There is usually small, round button that can be pressed and held. This will unlock the vehicle's doors and allow the driver to open them by hand.
Another way to get into a vehicle that is locked is using the emergency override feature. This will allow the key fob to override functions that are not controlled by the theft-deterrent system. This will activate the alarm lights and sound to ensure that the doors, fuel filler lid, or liftgate is closed.
Transponder Chips
You'll have to replace it if your key fob has a transponder that is built into the head of the metal L-shaped key. The chips have an unique identification number that works with your car to start the engine.
When you insert your key and then turn it to ON, the antenna ring releases the radio frequency energy that gets to the transponder chip that's in the metal key. The chip responds with an identifier that is transmitted to the antenna ring, telling the car that it's a valid key.
Most Mazdas are equipped with a rolling code transponder chip which changes its code each time you turn the key. This means that the key you're using isn't going to work with your car until you have a duplicate using the same code in the ignition cylinder.
It's not difficult to create your own replacement key. If you're able find an operational key, put it inside your Mazda and set the ignition to ON. You can copy the data from the key to another key if it is able to start your Mazda. You can also try using the eraser process on your key fob to erase the current code, if needed. It is important to note that this method isn't guarantee that it will work, as certain transponder chips that have been recycled might not function correctly.
Programming
The loss of your car keys can be an expensive and time-consuming experience. Mazda has made adding and programming an additional car key simple. You can do it in just a few steps and you do not have to pay the dealer for the service. You will not have to pay for towing or dealership fees if you own an additional car key.
You'll first need to purchase an additional battery for the key fob. You can purchase one at an hardware store or a big box retailer for about $10. You'll also require an open-ended screwdriver that is flat to open the fob. The screwdriver's head must fit in a small slot or a space on the back of the fob. After you've removed your 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. To do this, insert the first working key into the ignition, and then turn it ON. It should be on for about five seconds then switch off the ignition. Repeat the process with a different working key, and then your new (or spare) key. After you've completed this and your Mazda should be able to be started with the newly programmed keys. If not there may be a issue with the key fob or the vehicle.
