Keyless Entry Woes

[jaljjh07@yahoo.com]

Yeah I have tried with the batteries in both ways and still nothing. Any other ideas??!!

[Goliat6288]

i just read the whole thread. It could be the remote itself. Has it gotten wet? look up on ebay to see if you could find a cheap one. I would suggest looking for the keyless module first and typing it into ebay to see if any matching remotes come up.

i ordered a new one and it does the same thing i got it from ebay it could be bad but i hope not

I run through the diagnostics and when I get to this point:

•Horn sounds twice and hazard lights flash

The horn sounds twice but the hazard lights do not flash. They do work if I press them manually.

Anybody know what the next step is?

Thanks!

After going to the delaership every weekend for close to 3 months, someone finally gave me an old remote with all the buttons graphics worn off. No big deal. A salesman shows me how to program it(ignition 3 times, door jam 3 times, etc). Remote worked fine for a few months. Then it slowly started losing signal and I'd pretty much have to be right next to the car for it to work before it finally gave out all together. I replaced the battery and it didnt work. I took the remote to Auto Zone where they have an actually signal strength test to see if your remote is still functioning. The remote was shot. No signal. I went back to the dealership and demanded a new remote and refused to pay the $125+ for a brand new remote. After close to an hour of arguing with the sales manager, he gave me another used remote, no charge. Of course now they wanted $85 dollars to program it. I Already know the steps to program it and couldnt justify spending that much cash for them to perform that crazy easy procedure. I took it to Auto Zone and this remote was working but for some reason when I follow the programing steps the remote doesnt do anything. Ive done that diagnostic test. Everything went perfect. I called the dealership and they said it could be a problem with the Keyless control module. I cant find any information on that part anywhere on the net. I called auto zone to see if they carried that part or even knew where it was located in the car with no luck. If the diagnostic test ran smoothly then wouldnt that mean the module/receiving end in car is functioning properly? If not then does anyone know where the module is located? Also if anyone has some answer as to why I cant program this remote. Im trying to avoid going to the dealership at all cost. I dont trust them and think everyone there is a worthless parasite.

dON'T KNOW IF THIS WILL HELP, BUT IT DID FOR BOTH OF MY FOBS----OPEN THE FOB AND CHECK TO SEE IF THE LITTLE BUTTON IS SOLDERED ONTO THE CIRCUIT BOARD PROPERLY--MINE WAS NOT SO I BOUGHT A SOLDERING IRON FOR £10 AND RESOLDERED THE BUTTON ONTO THE BOARD AND LOW AND BEHOLD IT WORKED PERFECTLY--DONE THE SAME TO THE SECOND REMOTE AND THIS NOW WORKS TOO!!!RESULT AND ALL FOR A TENNER.

Would reprogramming the keyless system allow my mazda 6 to start? after i place the metal ring on the ring underneath the steering wheel the red light goes off but when I try to start the car the car shuts off. No electrical at all.

Hey nice points provided by you... Very useful one...

I've spent a good long while combing these forums, trying to find a solution to my problems, and after finding one, I figured I'd post for the benefit of others who are still doing the same.

When I got my Mazda6 (2005 model year, about a year ago), the previous owner gave me two keys, and three key fobs. He stated that two of them (which he had gotten from the original owner) stopped working, right around the same time. So, they did what many people on this forum suggested: buy a used remote from eBay and try to reprogram it.

I found the instructions for programming myself, and tried them to no avail. I would enter programming mode successfully, but would not get any reaction from the car after pressing buttons. I tried with all three remotes, numerous times. I tried all three remotes with new batteries, both inserted correctly and incorrectly. Nothing worked.

After doing the diagnostic (4 key turns instead of 3), and receiving a satisfactory response from the car (all systems normal), it seemed to me that the keyless entry receiver must have a problem receiving signal (possibility of a bad antenna). After checking output at a local Autozone (using their RF signal tester), it seemed as though the remotes themselves worked fine.

For awhile, it seemed that the situation was hopeless, and that I would have to replace the whole receiver, which I imagined would cost millions of dollars (especially since I was quoted at $150 from the dealer for a key fob by itself). The only other option was that the remotes WERE bad, but still transmitting something (maybe not the exact signal the car needed). Maybe they had gotten damaged, and no longer produced a usable signal. Maybe the used remote from eBay had the same problem, but was tested as working and sold as fully functional.

On a lark, I purchased a NEW (not USED) remote ($75, free shipping) from eBay. I got it in the mail a couple days later, and knowing the procedure by heart, opened the package in my car, entered programming mode, and...

SUCCESS. First try. I was a happy man.

Moral of the story:
It seems like most people here have this problem: One day, one remote stops working. They try the other one, and that doesn't work either. They replace the batteries, and they still don't work. Then, they find out about the reprogramming procedure, are very excited, try it, and then are not very excited when it fails.

If this sounds like your story, don't waste your time stressing about what could be going on. For me, all I needed was a new (not used) remote, and I was good. It's possible you could still get a used remote that will work from eBay, but it's a craps shoot; it seems that a lot of them out there are broken in some way (though they still transmit signal). Save yourself the hassle and just buy a new one.

I kept double-tapping the lock button yesterday while sitting on the couch watching football. She chirped back every single time
