Lost Keys

Losing your car keys used to be an inconvenience of a minor nature. You could replace keys at any hardware store, locksmith shop, or dealer and it was affordable to do so. The car's high-tech key fob can do much more than simply lock and start the vehicle. However, that added convenience comes with costs - more expensive replacements.

The key fob is equipped with an embedded security chip within it that sends a specific code to the car's system to enable you to open and start the engine. The key fob is capable of controlling some other features, including rolling down the windows if you're in a hot parking lot and summoning your car for easier reversing into an area that is tight (a feature offered on some Genesis GV60 and Hyundai Sonata sedans).

Mazda's remote controls aren't nearly as costly as other car manufacturers'. With a little know-how you can replace the battery in your key fob on your own. You'll require a flathead screwdriver along with the new CR2025 for this. Use mazda replacement keys and directions buttons to lock or unlock your doors before changing the batteries.

If you're looking to save money on the cost of a Mazda 3 key fob replacement you can find one online that is OEM and does not require programming by a dealer or locksmith. You'll find plenty of options on eBay however they may not have the exact color or logo as the key fob you currently have.

Lockouts

One of the most devastating things that can happen to a driver is being locked out of their car. There are several tricks drivers can employ to get inside their vehicle. It is best to first call their local Mazda dealership or locksmith. This is a good idea because it will probably be less expensive than calling for a tow truck and it will be faster as well. A dealer or locksmith must purchase a key code in the database in order to make a new fob. The cost is around $100. It's important to secure this code.

If you are stuck in the car, the second thing you can do is search for an auxiliary button on the bottom. There is usually a small, round button that can be pressed and held. This will open the doors of the vehicle, allowing the owner to open them by hand.

Another method to gain entry into the vehicle locked is by using the emergency override feature. This will allow you to use the key fob override any functions that have been disabled by the theft deterrent system. This will usually activate the warning lights for hazard and sound to confirm that the doors, lids for fuel-filler or liftgate are shut.

Transponder Chips


You'll need to replace it if the key fob is equipped with a transponder built into the metal head of the L-shaped key. The chips have an unique identification number that allows your vehicle to turn on the engine.

When you insert your key and then turn it to the ON position the antenna ring emits an impulsive radio frequency energy that will reach the transponder chip within the metal key. The chip responds by sending an encoded message to the antenna ring. This tells the car that the key is legitimate.

Most Mazdas use a rolling code transponder chip that alters its code each time you turn the key. This means that the key you're using will never work with your car until you have a second copy with the same exact code in the ignition cylinder.

It's not difficult to create your own replacement key. If you can locate an appropriate key and fits into your Mazda. Then, turn the ignition on. If the key is able to start your car, you can then copy the information to the other key that works. You can also try using the eraser process on the key fob to erase the current code, if necessary. It is important to note that this method is not guaranteed to work, as some recycled transponder chips may not respond correctly.

Programming

The loss of your car keys is costly and time-consuming. Luckily, Mazda has made it easy to program and add a third key. You can do it in only a few steps and you do not have to pay the dealer for the service. You will not have to pay for a tow or dealership fees if you own an extra car key.

You'll need to buy a new battery for the key fob. You can purchase one at an online retailer or at a hardware store for approximately $10. You'll also need a flathead screwdriver to open the fob. The screwdriver's head should fit in a small slot or a space on the back of the fob. Once you've removed the case, you'll need to replace the battery that was in the case with a new one.

Now you can program your new key fob. To do this, put the first working key into the ignition, and then turn it on. For about five seconds, and then turn it off. Repeat the process with another key that works before switching to the new (or extra) key. Once you have done this the Mazda should have the ability to be launched using the newly programmed keys. If it doesn't, there may be a problem with the key fob.
