How to replace it

As soon as your key fob battery dies, its functions become inoperable – which can be extremely annoying! However, replacing it yourself is relatively straightforward and only costs a few dollars to complete the task.

Pressing the auxiliary key button on the back of your fob to release its metal key is the first step toward opening its case. Next, find a notch in one of its halves and poke in a tape-wrapped flathead screwdriver to pry open its case.

Once the two halves of your key fob are separate, change out the CR2032 battery by placing its positive side facing upward. Reassemble your key fob pieces until you hear a click; this should allow you to start your car! These steps should work for all Mazda flip keys; for specific instructions please refer to your owner’s manual.

Tools you’ll need

Key fobs are essential in starting up your vehicle and are responsible for sending an electronic signal whenever either the lock or start button is pressed. When they stop functioning correctly, it’s often due to battery drain.

To replace it, you will require a new CR2032 battery – also used in clocks, calculators and photo equipment. Additionally, you’ll require a flathead screwdriver and something to pry apart the two halves of the key fob.

Look for a small space or notch on the seam that separates the front and back of your key fob case. Use either a coin, screwdriver, or thin knife to pry open this opening. Once removed from its case, locate its square compartment holding batteries, remove old one then insert new battery in same way – also be sure to set its orientation correctly!

Where to buy it

If you are having difficulty opening or starting your car using the keys fob buttons, a weak fob battery could be to blame. A new battery can usually be purchased at your local hardware store or big box retailer for around $10.

A 3-Volt coin battery like the CR2025 or CR2032 should work in most fobs; to find out which battery you need for your particular fob, consult its owner’s manual. Once you find the appropriate type, install it with its positive side facing up, ensuring its positive terminal faces up; snap two halves of its case closed again after installation.

If you don’t feel confident opening and replacing the battery yourself, most dealerships provide services to do it for you. However, they may decline programming an aftermarket fob remote key (with an aftermarket key blade). Therefore, for best results it would be wise to visit an automotive accessory or battery specialist shop who specialize in parts for your vehicle as they will also help find you a replacement key fob and cut its original key so as to fit with it.
