How to Fix Common Mazda 3 Key Problems
The Mazda 3 is an elegant compact car with a premium interior and a nimble handling. It's also a great value when compared to other small cars available.
Lost keys can be a real problem. It is costly to replace keys that are lost, and also taking your vehicle to the dealer to re-program your key.
Key not locking or unlocking the doors
It's dangerous to leave doors unlocked particularly when the vehicle is in motion. If the door is locked when the vehicle is in motion, passengers may be thrown out or injure themselves. Keep the keys out of reach of children to avoid this problem. Children might find them intriguing and may play with them. This could cause the power window or other controls to be activated and even cause the vehicle to move.
If you notice that the key fob won't lock or unlock the doors, the battery might be dead. The button-cell battery inside the keyfob is limited in its life span, so it is important to replace it on a regular basis. A good battery can last between two and four years. When replacing the battery, it's important to choose a replacement battery with the same voltage and size as the one that was originally.
Another reason why the key fob might not be working is a key pairing issue. It's possible that the keyfob wasn't properly connected to the vehicle at the time it was purchased. In this situation, the dealer will need to reset it. This can be accomplished in under an hour. The dealership can also reset the onboard computer to clear any residual electrical charge. However, this won't make the key fob more able to lock or unlock the doors.

If your Mazda 3 has been working for a while, but then suddenly stops and then it's possible that it's the remote keyless receiver module. This is especially likely if the key fob's internal chip is damaged. This could be due to several reasons, like dropping the key or being exposed to water.
Fortunately, the key fob's electronic chips are protected by rubber seals and should be fine even with a splash of water. Submerging the key fob into the ocean or in pool water can cause a significant issue due to the fact that salty water is extremely conductive and may harm the electronic components.
If your key fob is not working, it's likely that you're in need of an upgrade to the battery. A quick search on the web will reveal that there are countless third-party replacement batteries. It is important to keep in mind that these batteries might not work with your Mazda 3. It is best to purchase it from the dealer to ensure that it's compatible with your Mazda 3.
Once you've replaced the battery the key fob should work again. However, if your remote doesn't respond when press the lock button, the key is likely to be in power-saving mode. Press the lock button 5 times and hold it until the red light flashes.
Reprogramming the key
Mazda's keyless entry system allows you to unlock the car and begin it without the requirement for an ordinary key. This is a wonderful convenience, but the process of reprogramming your key or remote may seem complicated for some people. It also requires a special machine that only the dealer or automotive locksmith has access to. The machine is connected to the computer in the vehicle and begins the programming procedure for the new key or remote.
The first step is having at least two keys that function for the Mazda. You can then proceed to changing the programming of a spare key. The functions of the new FOB will be temporarily disabled to safeguard the vehicle from theft. Once you've reprogrammed the new key, you can enable these functions once more.
Then, you can use the new key to open the doors and start the engine. Try it out to make sure it works. If you're worried about losing the keys, it is a good idea to keep a spare key in the back of your hand.
It is simple to add an extra Mazda key. You can save money by following these easy steps. This will save you money on a tow bill and a spare key.
