How to Unlock Your Mazda 3 With a Broken Key Fob

Automotive technology can be great, with remote vehicle access having helped us unlock and lock our doors for years now. But what happens when the technology stops working? Like many technologies, the key fob on your Mazda can suffer from a dead battery and need to be replaced. So, what do you do in the meantime? We can show you how to easily unlock your Mazda 3 with a broken key fob.

Whether your key fob is damaged or just has a dying battery, there is a way for you to unlock your vehicle and start the car. Just follow the steps below:

Press and hold the auxiliary key release button on the underside of the key fob.
Grab the looped end at the top of your key fob.
Pull out the auxiliary key.
Use the auxiliary key to unlock the driver’s side door.

How to Start the Mazda 3 With a Broken or Dead Key

Now that you’ve managed to enter the vehicle with the auxiliary key, you’re going to need to know how to start your Mazda 3. At this point, the auxiliary key can be put back into the key fob, as the key fob can still be used to start your vehicle. This will only take a few extra steps.

Make sure the shifter is in the Park (P) or Neutral (N) position.
Depress the brake pedal.
The light on the engine start button should flash green.
Take your key fob and touch the back of it to the push button start.
When the green light on the engine start button stops flashing and remains continuously illuminated, press the push button start normally to start the engine.
It is recommended you allow the vehicle to idle for about 10 seconds.

Technology may be great, but it always helps to have a manual back up on hand. Thankfully, Mazda has you prepared for any situation.
