Need to Replace Key..not working 2006 Mazda 6
 

Hello, my key for my 2006 Mazda 6 has stopped working and my spare (never used) does not work either. Can the batteries be replaced on these? I tried to pry open without success. If these keys have non replaceable batteries, would a auto parts store like Auto Zone or O'Reilly be a good place to get one? Thanks

What doesn't work? The car won't start or the keyless entry not work?

Ugg, sorry for not being clear..at all. The unlock, lock, and trunk key do not work. Battery replaceable? Thank you.

Is it the flick out key type?

YES! That's the same as mine and will give it a go. I tried poking around in various places with a small screwdriver, but the video shows exactly where the releases are located. Thank you very much.

Update: got the battery key replaced and working fine!

FOB keys always take apart and clean them , these keys boxes are a real PIA ... and off course new battery helps too
glad to see your all set

Spot on pinstat! The key box was dirty! A bit tricky to open, but the new battery got it working fine again. I'm betting this car will roll to 275,000-300,00 mile mark since everything is working well. Smog check guy said emissions were as clean as new.
