Key Fob Programming
« on: April 23, 2010, 12:39:59 AM »
Have recently bought a Mazda3 1.6d and up to now am well pleased with it. The car only came with one key/remote fob.
Was quoted £250 at the dealer for second key - after picking myself up I searched around and ended up getting one off ebay. I can get it cut to match the original but i'm not too sure about programming it. Is this something I can do myself or am I at the mercy of the dealer again ?? Any help would be appreciated.

Excellent forum BTW.

The dealer will tell you they have to programme the key but you can do it yourself.  If you do a seach you will find some topics on the subject.

i think you have to have 2 keys that work to program another one. can have up to 4 assigned to the ECU. Your owners manual will tell you for sure.

on my USDM i needed 2 fobs to program another fob.

Thanks for replies - yep i've had a look around for details of how to do it but it does seem as though you need 2 keys to start with.
Looks like I may be at the mercy of the dealers, however I will try it myself first. Will update with outcome.
Cheers

I think there is a confusion on words here.

A key can only be programmed by the dealer as its a PATS system. The remote unit can be programmed by the owner.

to program a key fob you need to have the drivers door open and turn your igniton on and off 3 times waiting 2 seconds each time and then close and open your door 3 times again waiting a second or 2, then press the unlock button on your key fob and it should be programed in, you may need to do this a few times, if its the key you need then you have to go to mazda to have that done, hope this helps matey

I bought a remote fob off eBay for my 2004 Mazda 3 1.6D TS. It's a Visteon 41804. I've tried the above to programme the fob as well as trying these instructions from the States http://www.mazdas247.com/forum/showthread.php?74405-Programming-a-Spare-Remote-for-Mazda3 but I cannot get the car to go into programme mode. As far as I understand it after the 3 ignition on/offs and 3 doors open/closed the doors should lock then unlock signifying that the cars controller is in programme mode. Mine does not lock/unlock at this point so I don't even get the chance to try the fob programming. What does happen though is when I remove the key after all of the above the doors lock/unlock twice. Any suggestions?
I read somewhere to try ignition on/off 4 times to go into the diagnostics security test to reset all remotes for the car but that does not appear to resolve the issue either.
Thanks
Jamie

Try again.. It sounds like you are not quite doing it right.

Step 1: Open driver side door and leave open.

Step 2: Lock and Unlock the drivers door using the power door lock switch on the door

Step 3: Insert key into the ignition.

Step 4: 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.

Step 5: Close and open the drivers door 3 times. Leave door open after this step

Step 6: ECU should respond by locking and unlocking the doors once.

Step 7: Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors.

Step 8: Additional remotes, repeat Step 7 for up to 3 remotes total.

Step 9: 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

Willpower,
I go through steps 1-5 as you suggest but the car does not respond as per step 6 - it never locks/unlocks the doors once. Can I just confirm step 2 though? Whilst I have the drivers door open and try to lock the doors using the power door lock switch/central locking switch on the drivers door it immediately unlocks again - presumably as the door is open. So I cannot unlock the door at this point.
Hope that makes sense.
Thanks
Jamie

That is correct. You must leave the door open in order to continue. I know this works as I have done it myself. If you are following all the steps correctly and it still doesn't work for you, then I am at a bit of a loss.

Willpower,
I've seen elsewhere a reference to resetting the process of programming remotes by switching on/off the ignition 4 times - do you know anything about this and whether I could find a step by step detail of how to do this?
Thanks
Jamie

Do you mean the same as in Step 4 ?   This entails switching the ignition on/off 4 times. Once on /off , then again 3 times within 10 seconds.
Are you only doing it 3 times  ?

Willpower,
Yes I mean as in Step 4 but switching on/off the ignition 4 times instead of 3. To reset the programming do you need to go through steps 1 to 3 then as step 4 switch on/off the ignition 4 times with the drivers door open? Do you need to complete steps 5 and 6 thereafter to complete the reset?
Thanks -  I walk my dog and the lack of a remote means I have to take him onto the roadside to open the car so I'd rather get the remote working.
