Good Day

I purchased a 2007 Mazda 3 not to long ago, but the key fob was not working. After changing the battery and realizing that was not the issue, I searched and found programming instructions (unlock/lock, turn key on 3 times, open/shut door 3 times). I tried it a few times, no luck. Recently I thought I would give it another shot, but now my power locks don't work at all. The power locks no longer work on the driver or passenger side, nor does it work when I attempt to unlock the car from the outside (either opening the drivers side door or the hold to open all four doors). Please help!

Thank you so much for your time,
Tash
