    my mazda 3 2004 is driving me crazy. It has a great deal of trouble starting up in the morning - especially if its cold and I'll have to try and start the car at least 3 times before it can start up. A mazda dealer says its the fuel pump, but the car is so young and I am skeptical about paying 1000 to fix this problem. ANy advice??

If you have the manual there should be a fault tree code to fix your problem.

Mazda 6 Sport.recently changed batteries & Key doesn't always work;car start,open or lock doors. Red key light sometimes comes on? Any ideas?


use a scan tool to reset the ECM program as the battery removal may have corrupted the CPU program for all that you mention
if you changed the fob key battery ,it may be necessary to reprogram the key to the immobilizer.

It won't start. There is a car with a key light on and it says


The security system is activated, did you have a key made? If so it must be programmed. If the key is original then try the spare key, if that doesn't work you will need the system scanned for faults by the dealer.

After changing the fan belt at a garage, my Mazda 6 would not start. We trried using the extra key remote, but the car still will not start. What is the problem/solution? Is there a special Security...


Hi there,

Your Mazda 6 keys have transponders built in and only the correct key I.D. will activate your vehicle's immobilizer.

I'm at a loss as to how changing a fan belt could have altered your vehicle's immobilizer system - are you absolutely certain the garage hasn't disturbed any of the electronics?

First, we need to establish whether your vehicle's immobilizer still considers your keys as valid.

- Insert Key # 1 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 1 is considered still vaild.
- quickly turn Key 1 back to LOCK position and remove key.

Wait 5 seconds...

- Insert Key # 2 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 2 is considered still vaild.

Note: if Security light does not behave as above and keys still won't start your car, then your keys are no longer validated by the PCM

If this is the case, then unfortunately unlike other manufacturers, only Mazda will be able to re-program your key's ID into your vehicle's PCM. Contact your local Mazda Dealership to discuss.


Regards,

Scott

Lost my main set for a Mazda 323 (1999). Located the spare set, which starts the car, but the immobilizer kicks in. Is there a way of pairing my key to the car, or disconnecting the immobilizer, or is this...


The spare key is the valet key, You can call the dealer and have them cut you new keys for you car. You will need the VIN number and your registration for the car. If it doesn't have chip in it, they can make it for you in a couple of minutes. If it has the chip in it, they will have to order it. Without the chip, the key will cost between $20 and $30 dollars.

Hi. My mom just got a 2008 Mazda 5. On the way home from buying it, it would not start after she got gas, and was towed to mazda then yesterday, on a longer trip, it would not start again after she turned...


This model uses an engine immobilizer as part of the anti-theft. You could leave the wrong key in the ignition for days, with no success. The key has an electronic resistor built into it that the car's ignition will read. Even if the key is cut correctly, if the chip inside doesn't transmit the right signal, the car will not, under any condition, start............

GM's PASS-KEY System, such as those used on a Chevrolet, allows for any key that was cut to fit the ignition, but did not transmit the right code, to start the car after 17 minutes delay. The idea was that a thief would not want to wait around very long. Your mom's Mazda is more demanding, and therefore, more secure. Please review section 3, pages 20 through 22 of the owners manual. I've posted the link to a digital copy of it below this message. Do consult with your selling dealer, because this rarely happens on next-to-new cars. They should replace her keys and reprogram the immobilizer for free. It should definitely be covered under warranty, especially since she's only driven it such few times.

Hope this Helps!

1989 b2200 will start but won't stay running.


Many cars these days are equipped with an immobilizer. (you can find more information about the immobilizer in your owner's manual). The immobilizer allows the engine to run only if the correct key is used. If your car has an immobilizer, you probable see a "Security" or Key-shaped light coming on on the dashboard every time you turn the ignition ON. If this light is flashing when you turn the ignition ON, it could mean that there is some problem with an immobilizer or the system does not recognize the key. If the immobilizer doesn't recognize the key, the engine wold not start at all, or would start and then die in few seconds.
You can try a spare key, if it won't work, your dealer is the place to call. Sometimes, the key is just need to be reprogrammed. On some cars you can find the information how to reprogram the key in the owner's manual.
