I have managed to loose my OEM keyless entry for my '04 Mazda3 and have two questions:
1. Can you reset the pesky door alarm by just reseting the ECU, can I simply turn it off somehow without pulling the battery?
2. Where can I buy a new FOB (besides the dealership which I'm sure will be $$$)?
I did some searching and I think I found out how to program a new clicker, is this the correct method?:
-Open driver side door and leave open.
-Lock and Unlock the drivers door using the power door lock switch on the door
-Insert key into the ignition.
-Turn Key to ON position and return to Lock (off) position. Do this 3 times within 10 seconds. LEAVE key in the ignition in Lock (off) position.
-Close and open the drivers door 3 times. Leave door open after this step
-ECU should respond by locking and unlocking the doors once.
-Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors.
-Additional remotes, repeat Step 7 for up to 3 remotes total.
-Remove the key from the ignition and the ECU will respond a final time with a series (about 4) of door locks and unlocks. You're done!
Thank you all for your help, this problem has become quite annoying.
