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.
unlock the doors manually and it should reset your alarm.
Unlock the doors with the key or with the remote.
Weak batteries inside the remote.
To program a keyless remote control for a 2003 Honda Civic Si, first, sit in the driver's seat and close all doors. Insert the key into the ignition and turn it to the "On" position, then back to "Off" five times within 10 seconds. On the sixth turn, leave it in the "On" position; the doors should lock and unlock to indicate you're in programming mode. Press the "Lock" button on the remote within 5 seconds, and the doors will lock and unlock again, confirming the remote is programmed. Repeat this step for additional remotes, then turn the ignition off to exit programming mode.
