SOURCE: First: alarm went off on its own.(mazda 6 2003).

there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.

When ever a batter this new goes bad, it is either because it is not being charged, because there is something wrong with the charging system, or there is a constant drain even when the key is off.

To check the latter, with everything off, you remove a battery cable and see if the is any glow from a test light between the post and the cable. If there is, then you have something on that should not be, all the time. Then you pull fuses and disconnect things until it goes off.

To check if the charging system is not working, the easiest way it is to borrow a battery to get it started, (don't jump start a car if you can avoid it, because you can ruin an alternator when it starts, because it will kill itself trying to charge up that bad battery.) With the lights on, rev up the engine. They should get slightly brighter. Of with a volt meter, see it go from 12.5 to 13.5 volts, or so. If it does not go up, then your battery is all that was powering the car, and it won't last long like that.

The timing belt has broken. Fortunately though, according to my catalog, this is not an interference engine and the engine should not be damaged internally.

SOURCE: Mazda 6 problems 2006 when

what you may need is only a high mileage oil change should be using a castrol [in cold weather only] 30weight oil. i suggest a fram oil filter. i also suggest you use lucas oil treatment in with the oil change. your vehicle holds a 5quart oil change right? use 4 quarts of castrol oil and 1 quart of lucas oil treatment in with it that leaves one quart out.add the fram oil filter. if you are a do it your selfer you know what i mean. if not, do this,do not go to wal-mart,or a quick oil change place. use a local garage that you can trust. buy your supplies in advance, at autozone or advance auto,nappa auto, or wherever you trust for the best buy.all you need to pay for is labor only for oil change but demand they use your supplies and watch them to insure they do! the oil change is regular,but the lucas will cost $10.00 more on top of the oil can get a DEAL on fast track oil change,yeah right! do this once, and you will never use fast track again!you will get top engine lubrication which will remove that clatter. you will also gat 10.000 more miles between oil changes! you get what you pay for right? i have a 1994 ford explorer with over 400.000 miles on it now. just trying to see it i can go a million miles with it.i do my oil change every 45.000 miles. with no oil added in between oil changes.change your oil,use 30weight castrol oil in winter,use 40weight castrol in summer usea fram oil filter, the chatter will go away when you first start it. your engine will be lubricated well and you will be happy not hearing the chatter during the first start. thank you for choosing we are always here!

Security light flashing, car won't start for infiniti

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

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.

There is a flashing light from a symbol looking like a car with a key in it

This light is the security light warning, it indicates that a fault exists in the system, it will lock you out from starting the engine if not attended to soon. To find out what is the source of the problem making the light stay on you must have the dealer run an electronic scan of the systems control module.

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.

My security indidcator light is flashing every 2 seconds when my car is shut off. It stops flashing once I turn the vehicle on. How can I get it to stop flashing when the vehicle is off?

The security flashing is an indicator that your security system is armed and working.
It helps deter thiefs when they see the flashing light. They know if they try and break in your car the alarms will go off.
It is a good thing the red light is flashing.
Hope this helps ease your mind.
