The dealer usually charges about 10% to 15% less for the replacement key than a locksmith would charge. However, you will likely have to tow the car there to program the new key or remote. Therefore, the total price is usually higher.

Furthermore,

consider that if you have a locksmith come out and make you a new key outside regular business hours, the price may increase.

Finally,

If you have previously had your ignition cylinder replaced, which is quite common in older cars, this probably means that the code for the key may not be useful. In such cases, the key will have to be cut manually by a locksmith, or you will have to change the ignition again, and here the dealer can’t help.

Tips for Mazda CX-3 key fob replacement – What to ask and verify before and after you get a new key fob:

Mazda CX-3 key fob replacement - Emergency key and battery

Mazda CX-3 key fob replacement – Emergency key and battery

Very often when people get a replacement key fob, there are certain things they forget to check and ask the dealer or locksmith.

 

We gathered here the most relevant information and tips to make sure you won’t face a problem down the road.

First,

Make sure to get the key code of your Mazda CX-3 key fob – Every key fob, has a unique code which locksmiths and dealers use to know the exact cuts to match your ignition, door and trunk cylinders.

Ask and keep your key code in a safe place

Ask and keep your key code in a safe place

Obviously, this code is different from one car to another. This key code costs money, and before the locksmith or dealer cut you a new key fob, they must pay to get the code from the Mazda database, which may cost them up to $100. Make sure you write down this key code and keep it in a safe place. In case you lose your Mazda CX-3 key fob again in the future, it will cost you less to get a replacement, and the process will be faster.

Second,

Verify they cut you the emergency key, and that it works on the doors cylinders and trunk – Every key fob comes with an emergency key attached to it. The emergency key can be used to access the car in case the battery is dead.

Make sure they cut you the emergency key and that it works for each door and the trunk to avoid a future lockout situation. It should work smoothly, just like your house key. Don’t be lazy, check it on site.

Finally,

know which battery your Mazda CX-3 key fob has – These key fobs, like all key fobs, are battery operated. Make sure you know the type of battery you need and keep a spare one. (Mazda CX-3 key fobs usually use CR-2025 battery)

 

Q: Can I get a Mazda CX-3 key replacement by its VIN?

Mazda CX-3 key replacement by VIN

A: That depends on the year of manufacture of your car and the type of key you had.

The VIN gives dealers or automotive locksmiths the option of accessing the key code on file – i.e., to cut you a replacement key by code which makes the process fast and easy. There are however two things to consider:

  1. If your vehicle is older than 10 years, Mazda dealers will no longer have its key code record, so an automotive locksmith will be your only option to get a replacement key.
  2. For vehicles equipped with a transponder system and/or a remote/intelligent key/fob key, the codes should be available. However, as coding is required, you will have to either tow the car to the dealer, or have an automotive locksmith come and code the key on site.

Q: Mazda CX-3 key programming – which keys can you program yourself? Which keys require a programming tool? & more

Automotive locksmith programming a Mazda CX-3 key on-site

Automotive locksmith programming a Mazda CX-3 key on-site

A: Mazda has different types of keys. Some require programming, and some don’t. All transponder chip keys and/or smart key fobs need to be programmed. This process requires a special programming machine that only an automotive locksmith or the dealer has. There is no need to program non-transponder metal keys.

To make things simple, we divided all Mazda keys into two categories:

  1. No programming needed (Non-transponder keys).
  2. Keys that need to be programmed (Transponder or remote keys). These keys required the expertise of an automotive locksmith or the dealer.

 

No programming needed:

Mazda non-transponder keys are metal keys that have no chip in them, so no programming is needed.

Mazda CX-3 has none of this key type – all Mazda CX-3 keys have a chip and need to be programmed.

 

For Mazda CX-3 keys that need to be programmed, you will need an automotive locksmith or the dealer:

Car key coding machine for Mazda key fobs and transponder keys

Car key coding machine for Mazda key fobs and transponder keys

These keys, also known as remote smart keys, intelligent keys or key fobs, and transponder keys, have a security chip. Programming is needed. Also, a special machine is needed to program them. An automotive locksmith or dealer should do it for you. This process must be followed for most models made after 1998.
