I worked at a Toyota Dealership, a lot of times when new keys were cut they'd need to be programmed. I work and live in New Zealand by the way.
Unfortunately the owner to my understanding couldn't program/re-program the key, you must take it into your dealership to have it done. It involves the key itself in the car with the Toyota Mechanic doing a code via opening and closing doors, it's a weird process. But that's how it's programmed. I don't believe it can be done yourself. It's a security measure.

Take it to the dealer
Take it to the dealer.
To reprogram the alarm remote for a Porsche boxster, one must put the key into the ignition and turn to position 1, first click. After, you must then turn the ignition off and leave the key in for approximately 15 seconds. The last step is to start the car; this will successfully reprogram the remote.

If it is the same as the 306, which I would of thought likely, off the top of my head you get your spare key and set it to 'a' position in the ignition barrel. The new remote key you then point at the infra red receiver and hold the button down for 5-10 seconds. Hopefully then if you remove the spare key, the remote locking should then work.
use your key and reprogram your remote from the dealership
One reason that your remote key will not unlock your Mazda 6 is that a fuse is blown. You may need to replace the batteries in the remote or reprogram the remote. A bad body control module is another reason the remote will not unlock the doors.
You turn the key to the ll position or second click and press the remote pad to open the car. The central locking and indicators for the immobilizer should activate and that is the key programmed. Hope this helps.

That's your remote control for unlocking / locking the doors etc ( key FOB )
In cars with central locking, or remote locking, a solenoid is fitted to the locking mechanism. When the remote button is pressed (usually on the key) a signal is sent to the central locking control system. The received signal closes an electronic gate in the controller and current from the cars battery is switched to the solenoid on the lock. The force generated locks or unlocks the door as required.
