Lockouts

A driver who is locked out of their vehicle is one of the worst things to happen. There are, however, a few techniques that drivers can employ to get back into their car. First, they should try calling the local locksmith or Mazda dealership. This is a great idea because it will probably be cheaper than calling a tow truck, and it's faster as well.

The antenna ring releases a burst of radio frequency energy when you insert your metal key and switch it on. The energy reaches the chip's transponder located in the key. The chip then responds with an encoded code that is sent to the antenna ring, telling the car that it's an authentic key.

Most Mazdas come with transponder chips that have an evolving code that changes each time you turn it. This means that the key you're using isn't going to work on your vehicle until you've got a copy with the same exact code inside the ignition cylinder.
