Changing mazda 3 car keys in Your Mazda 3 Key Fob
There's nothing more annoying than returning to your vehicle after a long day and realizing that the key fob battery is dead. This is a straightforward solution that can be accomplished at a major box retailer or hardware store.
Incorporating a spare key fob to your Mazda 3 can be an affordable solution to free yourself from having to be towed to the dealership and having them reprogram your keys.
Battery Replacement
You can replace the battery on your Mazda 3 keyfob at home. But, it is best to replace the battery when it fails, or when the key fob displays a message in the multi-information display saying, "Low key fob battery. Replace battery."
To open the key fob case you'll need a tape-wrapped flathead screwdriver as well as some patience. Locate a notch or gap in the bottom portion of the metal of your Mazda 3's key fob and insert the head of the screwdriver into it to cut off the lower half. Repeat the procedure for the top piece of metal but be careful not to scratch the rubber ring at the bottom of the case.
You'll find a slot on each side of the fob case that houses the battery. Make use of the tape-wrapped flathead screwdriver to gently open the case, starting with one side and moving to the other. Remove the old battery and put in the new CR2025 to ensure that it's in the right orientation for proper polarity. Attach the cap to the battery again and secure both sides of your key fob case by pressing until they click.
Once you've replaced your battery, test the fob to ensure it is working by locking and unlocking your doors. If everything is in order you're now able to use the Mazda 3's remote functions to drive again!
Pairing Issues
This could mean that the transmitter in your car is damaged. This is usually a matter of an expert repair and may need a new key fob.
If you've tried to replace the battery and reprogramme the key fob but it hasn't worked the chip inside the key fob may be defective. This can happen when the key fob has been dropped on hard surfaces and exposed to salt water or even touched by dirty hands.
You will need to locate the tiny "key" that is inserted into the seam, in order to remove the circuit board to identify the problem. You can then check the chip for damage or corrosion. To avoid damaging the chip, it is recommended to clean the chip with a new paper towel.
If you are unsure it is possible to check the battery connector terminals for cracks, or breaks. If this is the situation it is possible to solder the terminals back to their place will usually bring back functionality to the key fob. You can also check the buttons for damage or wear. If the buttons are loose, they can easily be soldered back into place in the event that a button has physically snapped off.
Interference Signals
Few things are more frustrating than glancing at the "No Fob Detected" message when trying to start your vehicle. It usually happens at the most unpopular time, such as when you're running late for work or when you have to pick up children from daycare or school. The good thing is that there are steps you can take to investigate the issue and figure out the root of the problem.
Interference signals can cause the remote key fob to stop functioning properly. This could be caused by objects like buildings, weather conditions, and transmitters that operate on the same frequency. Interference can also occur when you have aftermarket equipment installed in the vehicle that transmits at the same frequency as the key fob.
Additionally, if the key fob is exposed to water or salt seawater, it may be damaged. The rubber seals on the electronic chip could be damaged by water, especially when it is submerged over an extended period of time, such as in the ocean or a pool at the beach. This could cause the chip to cease working and will require replacement of the key fob. If you have a programmeable key it is possible to clean the chip with isopropyl alcohol or an electronic cleaner to aid in its get back to its original functionality. If this doesn't work, it is likely that the chip has burned out and requires replacement.
Locking/Unlocking of the Doors
The buttons on the fob's key send electronic signals to the solenoid of the car, which transforms this signal into a mechanical action. It locks and unlocks doors. If your door lock fails to work it could be because of an issue with the solenoid. This requires professionals from repair shops to look into.
A dead battery of 12 volts can also prevent the fob from functioning properly. This happens when the battery's charge is lost or if the contacts get corroded and stop transferring electricity. The good news is that a new battery can solve this issue in only minutes.
If the key fob isn't working after you replace the battery or program it again then the problem may be with the receiver module. This device interprets radio frequency signals sent by the key fob to control the vehicle. It can be expensive to repair if the device becomes defective.
To confirm if this true, place your spare key in the key slot. Then, turn the ignition ON. Press the key fob two times within 10 seconds, but without removing it. The Mazda 3 system will now connect the key to the car and you can use it as your primary remote for driving. This allows you to program up three keys.
