Stock Keyless Entry Fob Doesn't work
Ok, I've done some searching on this and I'm only finding threads about upgrading to the switchblade key fob.
So I get up this morning and my 2004 stock key less entry fob doesn't seem to open the car. I figure its the battery, so I swapped a new one into the unit. Still no workie. My other fob also appears to have a dead battery, so I swapped it out too. No luck on getting that unit to open the car either.
Do you have to reprogram after you simply swap a battery? Thanks guys

Hi Brillo.
That sucks.
As far as similar problems, I found this post by dannobre:
You might want to PM Dan and see what he found after the fact.
Good luck.

Taka has an easy Thread here on how to do...

You should not have to reprogram after changing a battery. The Fob simply transmits an embedded unique number code that the car electronics has recorded as valid. Changing the battery should not alter the code that is transmitted. I doubt the fob is sophisticated enough to be sending anything complicated like the rolling codes of a garage door opener. Make sure the battery is in correctly and any connections are clean and unbroken.

I think when you re-program the new key you have to have your old ones handy to re-do ALL at the same time....probably because a new code is issued, so the old code will no longer work in the keys that you thought were OK.

What year is your car? If you own a 2004 and uses the keychain FOB, you will: 1. Need to have the dealer program the FOB. OR 2. Buy a switchblade (like the one from eBay linked below) and follow the programming instructions for the Switchblade FOB.
MAZDA SWITCHBLADE KEY/FOB
I have tried Takahashi's versions of programming the FOB for the 2004 RX-8 and niether worked. It did on the switchblade, however. The only sure way of reprogramming the 2004 FOB when the battery dies is through the dealer using the Mazda-Modular Diagnostic System.
