It’s a common question for Mazda 3 2012 owners: can you program a new car remote yourself? The short answer is yes, Mazda 3 remotes are designed to be programmable. However, the process depends on your current situation, specifically how many working keys you already have.
If you are fortunate enough to have two functioning keys, you’re in a good position. Mazda allows owners with two existing keys to program additional remotes themselves. This is a convenient feature that saves you a trip to the dealership and potential programming fees. You can add up to eight keys in total using this self-programming method. This makes it easy to have spare keys or add remotes if you purchase new ones online.
However, if you’re in the situation of only having one working key, the process becomes a bit more involved. In this case, you will need to visit a Mazda dealership to program a second key. Due to security protocols, dealerships use specialized equipment to connect to your car’s computer and program new keys when you only have a single existing key. This process at the dealership typically takes around 45 minutes. Be aware that the cost for this service can vary. While some dealerships might offer programming for around $50-$75, others could charge upwards of $150 or even perform it for free as a courtesy. It’s always best to call your local dealer to get a price quote beforehand.
Once you have that crucial second programmed key from the dealership, you unlock the ability to program any subsequent keys yourself, saving you time and money in the future. A smart move after getting a second key professionally programmed is to consider purchasing a third regular key. Having three keys provides a safety net. If you happen to lose one, you can easily program a replacement yourself, ensuring you always have at least two working keys and avoiding the need to return to the dealership for programming services again.
Regarding remote types, for the Mazda 3, flip remotes from other Mazda models like the MX-5 (three-button) and Mazda 6 sedan (four-button) are compatible. Many Mazda 3 owners opt for the four-button Mazda 6 remote, even though the trunk button might not function on the Mazda 3. The MX-5 remote tends to be significantly more expensive.
It’s important to note the model year of your Mazda 3. If your Mazda 3 is a 2007 or newer model, using original equipment manufacturer (OEM) flip keys becomes more challenging. Mazda changed the Keyless Entry Unit (KEU) in 2007, making OEM flip keys from earlier models incompatible. For 2007 and newer Mazda 3s, aftermarket housings are often the only practical solution if you desire a flip-style key. These housings allow you to transplant the circuit board from your original remote and the transponder chip from your existing key into the aftermarket flip key casing.
